Poland Solar PV Boom drives record installations, rooftop and utility-scale growth, EU-aligned incentives, net metering, PPAs, and auctions, pushing capacity toward 8.3 GW by 2024 while prosumers, grid upgrades, and energy management expand.

 

Key Points

A rapid expansion of Poland's PV market, driven by incentives, PPAs, and prosumers across rooftop and utility-scale.

✅ 2.2 GW added in 2020, triple 2019, led by small-scale prosumers

✅ Incentives: My Current, Clean Air, Agroenergia, net metering

✅ Growth toward 8.3 GW by 2024; PPAs and auctions scale utility

 

Photovoltaics (PV) is booming in Poland. According to SolarPower Europe, 2.2 gigawatts (GW) of solar power was installed in the country in 2020 - nearly three times as much as the 823 megawatts (MW) installed in 2019. This places Poland fourth across Europe, behind Germany, where a solar power boost has been underway (4.8 GW added in 2020), the Netherlands (2.8 GW) and Spain (2.6 GW). So all eyes in the industry are on the up-and-coming Polish market. The solar industry will come together at Intersolar Europe Restart 2021, taking place from October 6 to 8 at Messe München. As part of The smarter E Europe Restart 2021, manufacturers, suppliers, distributors and service providers will all present their products and innovations at the world's leading exhibition for the solar industry.

All signs point to continued strong growth, with renewables on course to set records across markets. An intermediate, more conservative EU Market Outlook forecast from SolarPower Europe expects the Polish solar market to grow by 35 percent annually, meaning that it will have achieved a PV capacity of 8.3 GW by 2024 as solar reshapes Northern Europe's power prices over the medium term. "PV in Poland is booming at every level - from private and commercial PV rooftop systems to large free-standing installations," says Dr. Stanislaw Pietruszko, President of the Polish Society for Photovoltaics (PV Poland). According to the PV Poland, the number of registered small-scale systems - those under 50 kilowatts (kW) - with an average capacity of 6.5 kilowatts (kW) grew from 155,000 (992 MW) at the end of 2019 to 457,400 (3 GW) by the end of 2020. These small-scale systems account for 75 percent of all PV capacity installed in Poland. Larger PV projects with a capacity of 4 GW have already been approved for grid connection, further attesting to the forecast growth.

8,000 people employed in the PV industry
Andrzej Kazmierski, Deputy Director of the Department for Low-emission Economy within the Polish Ministry of Economic Development, Labour and Technology, explained in the Intersolar Europe webinar "A Rising Star: PV Market Poland" at the end of March 2021 that the PV market volume in Poland currently amounts to 2.2 billion euros, with 8,000 people employed in the industry. According to Kazmierski, the implementation of the Renewable Energy Directive (RED II) in the EU, intended to promote energy communities and collective prosumers as well as long-term power purchase agreements (PPAs), will be a critical challenge, and ongoing Berlin PV barriers debates highlight the importance of regulatory coordination. Renewable energy must be integrated with greater focus into the energy system, and energy management and the grids themselves must be significantly expanded as researchers work to improve solar and wind integration. The government seeks to create a framework for stable market growth as well as to strengthen local value creation.


Government incentive programs in Poland
In addition to drastically reduced PV costs, reinforced by China's rapid PV expansion, and growing environmental consciousness, the Polish PV market is being advanced by an array of government-funded incentive programs such as My Current (230 million euros) and Clean Air as well as thermo-modernization. The incentive program Agroenergia (50 million euros) is specifically geared toward farmers and offers low-interest loans or direct subsidies for the construction of solar installations with capacities between 50 kW and 1 MW. Incentive programs for net metering have been extended to small and medium enterprises to provide stronger support for prosumers. Solar installations producing less than 50 kW benefit from a lower value-added tax of just eight percent (compared to the typical 23 percent). The acquisition and installation costs can be offset against income, in turn reducing income tax.
Government-funded auctions are also used to finance large-scale facilities, where the government selects operators of systems running on renewable energy who offer the lowest electricity price and funds the construction of their facilities. The winner of an auction back in December was an investment project for the construction of a 200 MW solar park in the Pomeranian Voivodeship.


Companies turn to solar power for self-consumption
Furthermore, Poland is now playing host to larger solar projects that do not rely on subsidies, as Europe's demand lifts US equipment makers amid supply shifts, such as a 64 MW solar farm in Witnica being built on the border to Germany whose electricity will be sold to a cement factory via a multi-year power purchase agreement. A new factory in Konin (Wielkopolska Voivodeship) for battery cathode materials to be used in electric cars will be powered with 100-percent renewable electricity. Plus, large companies are increasingly turning to solar power for self-consumption. For example, a leading manufacturer of metal furniture in Suwalki (Podlaskie Voivodeship) in northeastern Poland has recently started meeting its demand using a 2 MW roof-mounted and free-standing installation on the company premises.

Wind power grows despite Covid-19

Global Wind Power Growth will hit record installations, buoying renewable energy, offshore wind, onshore capacity, and economic recovery, as GWEC forecasts resilient post-Covid markets led by China and the US with strong investment and jobs.

 

Key Points

Global Wind Power Growth is the forecast rise in capacity driving renewable energy, jobs, and lower emissions.

✅ 71.3 GW installed in 2020; only 6% below pre-Covid forecast

✅ 348 GW added by 2024; nearly 1,000 GW total capacity

✅ Offshore wind resilient; 6.5 GW in 2020, China-led

 

Wind power will continue to show record growth, as renewables set to shatter records over the next five years despite the impacts of the Covid-19 crisis, and will make a crucial contribution to economic recovery... According to the latest market outlook by GWEC Market Intelligence, 71.3GW of wind power capacity is expected to be installed in 2020, which is only a 6% reduction from pre-Covid forecasts. This is a significant increase from original predictions that expected wind power installations to be reduced by up to 20 per cent due to the pandemic, demonstrating the resilience of the wind power industry across the globe.

From 2020 to 2024, the cumulative global wind energy market will grow at a compound annual rate of 8.5% and installing 348GW of new capacity, bringing total global wind power capacity to nearly 1,000GW by the end of 2024, which is an increase of 54% for total wind power installations compared to 2019. While some project completion dates have been pushed into 2021 due to the pandemic, next year is expected to be a record year for the wind industry with 78GW of new wind capacity forecasted to be installed in 2021. Over 50% of the onshore wind capacity added between 2020 to 2024 will be installed in China and the US, where U.S. solar and wind growth is supported by favourable government plans, led by installation rushes to meet subsidy deadlines.

The offshore wind sector has been largely shielded from the impacts of the Covid-19 crisis, GWEC Market Intelligence has indeed increased its forecast for offshore wind by 5 per cent to 6.5 GW of new installations in 2020, another record year for the industry, as offshore wind's $1 trillion outlook comes into focus, led by the installation rush in China. Up until 2024, over 48GW of new offshore wind capacity is expected to be installed, with another 157GW forecasted to be installed from 2025 to 2030 across key markets such as offshore wind in the UK and Asia.

“While the Covid-19 crisis has impacted every industry across the world, wind power has continued to grow and thrive. This is no surprise given the cost competitiveness of wind energy and the need to rapidly reproduce carbon emissions. Fossil fuel industries face market fluctuations and require bailouts to stay afloat, while wind turbines across the world have continued to spin and provide affordable, clean energy to citizens everywhere," says Ben Backwell, CEO of GWEC.

“Thanks to the localised nature of wind power supply chains and project construction, the sector has continued to generate billions in local investment and thousands of jobs to support economic recovery. However, in order to tap into the full potential of wind power to drive a green recovery, governments must ensure that energy markets and policies allow a continued ramp up in investment in wind and other renewables, and avoid unintended effects such as the Solar ITC extension impact on the US wind market, while disincentivising investment in expensive and declining fossil fuel industries," he says.

Biggest markets

China and the US will continue to be the two main markets driving growth over the next few years, with U.S. wind power surges underscoring the momentum. "We have increased or maintained our forecasts for onshore wind in regions such as Latin America, North America, Africa, and the Middle East over the next five years, with only minor decreases in Asia Pacific and Europe. However, these reductions are not necessarily a direct impact of Covid-19, but also a symptom of pre-existing regulatory issues, such as protracted permitting procedures, which are slowing down installations. In particular, offshore wind has demonstrated its resilience by exceeding our pre-pandemic forecasts for 2020, and will be an important source of growth in the decade ahead," Feng Zhao, strategy director at GWEC.

“We have seen a series of carbon neutrality commitments by major economies such as China, Japan and South Korea over the past few weeks. Since wind power is a key technology for decarbonisation, building on the evolution in 2016, these targets will increase the forecast for wind power over the next few decades. However, the right enabling regulatory and policy frameworks must be in place to accelerate renewable energy growth to meet these targets. China, the world’s largest wind power market and largest carbon emitter, has pledged to go carbon-neutral by 2060. To have a chance at achieving this target, we need to be installing 50GW of wind power per year in China from now until 2025, and then 60GW from 2026 onwards. It is crucial that governments firm up carbon neutrality targets with tangible actions to drive wind and other renewable energy growth at the levels needed to achieve these aims”, he says.

Electric vehicles can now power your home for three days

Vehicle-to-Home (V2H) Power enables EVs to act as backup generators and home batteries, using bidirectional charging, inverters, and rooftop solar to cut energy costs, stabilize the grid, and provide resilient, outage-proof electricity.

 

Key Points

Vehicle-to-Home (V2H) Power lets EV batteries run household circuits via bidirectional charging and an inverter.

✅ Cuts energy bills using solar, time-of-use rates, and storage

✅ Provides resilient backup during outages, storms, and blackouts

✅ Enables grid services via V2G/V2H with smart chargers

 

When the power went out at Nate Graham’s New Mexico home last year, his family huddled around a fireplace in the cold and dark. Even the gas furnace was out, with no electricity for the fan. After failing to coax enough heat from the wood-burning fireplace, Graham’s wife and two children decamped for the comfort of a relative’s house until electricity returned two days later.

The next time the power failed, Graham was prepared. He had a power strip and a $150 inverter, a device that converts direct current from batteries into the alternating current needed to run appliances, hooked up to his new Chevy Bolt, an electric vehicle. The Bolt’s battery powered his refrigerator, lights and other crucial devices with ease. As the rest of his neighborhood outside Albuquerque languished in darkness, Graham’s family life continued virtually unchanged. “It was a complete game changer making power outages a nonissue,” says Graham, 35, a manager at a software company. “It lasted a day-and-a-half, but it could have gone much longer.”

Today, Graham primarily powers his home appliances with rooftop solar panels and, when the power goes out, his Chevy Bolt. He has cut his monthly energy bill from about $220 to $8 per month. “I’m not a rich person, but it was relatively easy,” says Graham “You wind up in a magical position with no [natural] gas, no oil and no gasoline bill.”

Graham is a preview of what some automakers are now promising anyone with an EV: An enormous home battery on wheels that can reverse the flow of electricity to power the entire home through the main electric panel.

Beyond serving as an emissions-free backup generator, the EV has the potential of revolutionizing the car’s role in American society, with California grid programs piloting vehicle-to-grid uses, transforming it from an enabler of a carbon-intensive existence into a key step in the nation’s transition into renewable energy.

Home solar panels had already been chipping away at the United States’ centralized power system, forcing utilities to make electricity transfer a two-way street. More recently, home batteries have allowed households with solar arrays to become energy traders, recharging when electricity prices are low, replacing grid power when prices are high, and then sell electricity back to the grid for a profit during peak hours.

But batteries are expensive. Using EVs makes this kind of home setup cheaper and a real possibility for more Americans as the American EV boom accelerates nationwide.

So there may be a time, perhaps soon, when your car not only gets you from point A to point B, but also serves as the hub of your personal power plant.

I looked into new vehicles and hardware to answer the most common questions about how to power your home (and the grid) with your car.


Why power your home with an EV battery

America’s grid is not in good shape. Prices are up and reliability is down, and many state power grids face new challenges from rising EV adoption. Since 2000, the number of major outages has risen from less than two dozen to more than 180 per year, based on federal data, the Wall Street Journal reports. The average utility customer in 2020 endured about eight hours of power interruptions, double the previous decade.

Utilities’ relationship with their customers is set to get even rockier. Residential electricity prices, which have risen 21 percent since 2008, are predicted to keep climbing as utilities spend more than $1 trillion upgrading infrastructure, erecting transmission lines for renewable energy and protecting against extreme weather, even though grids can handle EV loads with proper management and planning.

U.S. homeowners, increasingly, are opting out. About 8 percent of them have installed solar panels. An increasing number are adding home batteries from companies such as LG, Tesla and Panasonic. These are essentially banks of battery cells, similar to those in your laptop, capable of storing energy and discharging electricity.

EnergySage, a renewable energy marketplace, says two-thirds of its customers now request battery quotes when soliciting bids for home solar panels, and about 15 percent install them. This setup allows homeowners to declare (at least partial) independence from the grid by storing and consuming solar power overnight, as well as supplying electricity during outages.

But it doesn’t come cheap. The average home consumes about 20 kilowatt-hours per day, a measure of energy over time. That works out to about $15,000 for enough batteries on your wall to ensure a full day of backup power (although the net cost is lower after incentives and other potential savings).

 

How an EV battery can power your home

Ford changed how customers saw their trucks when it rolled out a hybrid version of the F-150, says Ryan O’Gorman of Ford’s energy services program. The truck doubles as a generator sporting as many as 11 outlets spread around the vehicle, including a 240-volt outlet typically used for appliances like clothes dryers. During disasters like the 2021 ice storm that left millions of Texans without electricity, Ford dealers lent out their hybrid F-150s as home generators, showing how mobile energy storage can bring new flexibility during outages.

The Lightning, the fully electric version of the F-150, takes the next step by offering home backup power. Under each Lightning sits a massive 98 kWh to 131 kWh battery pack. That’s enough energy, Ford estimates, to power a home for three days (10 days if rationing). “The vehicle has an immense amount of power to move that much metal down the road at 80 mph,” says O’Gorman.

The underwater 'kites' generating electricity as they move

Faroe Islands Tidal Kites harness predictable ocean energy with underwater turbines by Minesto, flying figure-eight paths in fjords to amplify tidal power and deliver renewable electricity to SEV's grid near Vestmanna at megawatt scale.

 

Key Points

Subsea turbines that fly figure-eight paths to harvest tidal currents, delivering reliable renewable power to the grid.

✅ Figure-eight control amplifies speed vs. ambient current

✅ Predictable baseload complementing wind and hydro

✅ 1.2 MW Dragon-class units planned for Faroese fjords

 

Known as "sea dragons" or "tidal kites", they look like aircraft, but these are in fact high-tech tidal turbines, part of broader ocean and river power efforts generating electricity from the power of the ocean.

The two kites - with a five-metre (16ft) wingspan - move underwater in a figure-of-eight pattern, absorbing energy from the running tide. They are tethered to the fjord seabed by 40-metre metal cables.

Their movement is generated by the lift exerted by the water flow - just as a plane flies by the force of air flowing over its wings.

Other forms of tidal power use technology similar to terrestrial wind turbines, and emerging kite-based wind power shows the concept's versatility, but the kites are something different.

The moving "flight path" allows the kite to sweep a larger area at a speed several times greater than that of the underwater current. This, in turn, enables the machines to amplify the amount of energy generated by the water alone.

An on-board computer steers the kite into the prevailing current, then idles it at slack tide, maintaining a constant depth in the water column. If there were several kites working at once, the machines would be spaced far enough apart to avoid collisions.

The electricity is sent via the tethering cables to others on the seabed, and then to an onshore control station near the coastal town of Vestmanna.

The technology has been developed by Swedish engineering firm Minesto, founded back in 2007 as a spin-off from the country's plane manufacturer, Saab.

The two kites in the Faroe Islands have been contributing energy to Faroe's electricity company SEV, and the islands' national grid, on an experimental basis over the past year.

Each kite can produce enough electricity to power approximately 50 to 70 homes.

But according to Minesto chief executive, Martin Edlund, larger-scale beasts will enter the fjord in 2022.

"The new kites will have a 12-metre wingspan, and can each generate 1.2 megawatts of power [a megawatt is 1,000 kilowatts]," he says. "We believe an array of these Dragon-class kites will produce enough electricity to power half of the households in the Faroes."

The 17 inhabited Faroe islands are an autonomous territory of Denmark. Located halfway between Shetland and Iceland, in a region where U.K. wind lessons resonate, they are home to just over 50,000 people.

Known for their high winds, persistent rainfall and rough seas, the islands have never been an easy place to live. Fishing is the primary industry, accounting for more than 90% of all exports.

The hope for the underwater kites is that they will help the Faroe Islands achieve its target of net-zero emission energy generation by 2030, with advances in wave energy complementing tidal resources along the way.

While hydro-electric power currently contributes around 40% of the islands' energy needs, wind power contributes around 12% and fossil fuels - in the form of diesel imported by sea - still account for almost half.

Mr Edlund says that the kites will be a particularly useful back-up when the weather is calm. "We had an unusual summer in 2021 in Faroes, with about two months with virtually no wind," he says.

"In an island location there is no possibility of bringing in power connections from another country, and tidal energy for remote communities can help, when supplies run low. The tidal motion is almost perpetual, and we see it as a crucial addition to the net zero goals of the next decade."

Minesto has also been testing its kites in Northern Ireland and Wales, where offshore wind in the UK is powering rapid growth, and it plans to install a farm off the coast of Anglesey, plus projects in Taiwan and Florida.

The Faroe Islands' drive towards more environmental sustainability extends to its wider business community, with surging offshore wind investment providing global momentum. The locals have formed a new umbrella organisation - Burðardygt Vinnulív (Faroese Business Sustainability Initiative).

It currently has 12 high-profile members - key players in local business sectors such as hotels, energy, salmon farming, banking and shipping.

The initiative's chief executive - Ana Holden-Peters - believes the strong tradition of working collaboratively in the islands has spurred on the process. "These businesses have committed to sustainability goals which will be independently assessed," she says.

"Our members are asking how they can make a positive contribution to the national effort. When people here take on a new idea, the small scale of our society means it can progress very rapidly."

One of the islands' main salmon exporters - Hiddenfjord - is also doing its bit, by ceasing the air freighting of its fresh fish. Thought to be a global first for the Atlantic salmon industry, it is now exporting solely via sea cargo instead.

According to the firm's managing director Atli Gregersen this will reduce its transportation CO2 emissions by more than 90%. However it is a bold move commercially as it means that its salmon now takes much longer to get to key markets.

For example, using air freight, it could get its salmon to New York City within two days, but it now takes more than a week by sea.

What has made this possible is better chilling technology that keeps the fresh fish constantly very cold, but without the damaging impact of deep freezing it. So the fish is kept at -3C, rather than the -18C or below of typical commercial frozen food transportation.

"It's taken years to perfect a system that maintains premium quality salmon transported for sea freight rather than plane," says Mr Gregersen. "And that includes stress-free harvesting, as well as an unbroken cold-chain that is closely monitored for longer shelf life.

"We hope, having shown it can be done, that other producers will follow our lead - and accept the idea that salmon were never meant to fly."

Back in the Faroe Island's fjords, a firm called Ocean Rainforest is farming seaweed.

The crop is already used for human food, added to cosmetics, and vitamin supplements, but the firm's managing director Olavur Gregersen is especially keen on the potential of fermented seaweed being used as an additive to cattle feed.

He points to research which appears to show that if cows are given seaweed to eat it reduces the amount of methane gas that they exhale.

"A single cow will burp between 200 and 500 litres of methane every day, as it digests," says Mr Gregersen. "For a dairy cow that's three tonnes per animal per year.

"But we have scientific evidence to show that the antioxidants and tannins in seaweed can significantly reduce the development of methane in the animal's stomach. A seaweed farm covering just 10% of the largest planned North Sea wind farm could reduce the methane emissions from Danish dairy cattle by 50%."

The technology that Ocean Rainforest uses to farm its four different species of seaweed is relatively simple. Tiny algal seedlings are affixed to a rope which dangles in the water, and they grow rapidly. The line is lifted using a winch and the seaweed strands simply cut off with a knife. The line goes back into the water, and the seaweed starts growing again.

Currently, Ocean Rainforest is harvesting around 200 tonnes of seaweed per annum in the Faroe Islands, but plans to scale this up to 8,000 tonnes by 2025. Production may also be expanded to other areas in Europe and North America.

Can food waste be turned into green hydrogen to produce electricity?

Food Waste to Green Hydrogen uses biological production to create clean energy, enabling waste-to-energy, decarbonization, and renewable hydrogen for electricity, industrial processes, and transport fuels, developed at Purdue University Northwest with Purdue Research Foundation licensing.

 

Key Points

A biological process converting food waste into renewable hydrogen for clean energy, electricity, industry, and transport.

✅ Enables rapid, scalable waste-to-hydrogen deployment

✅ Supports grid power, industrial heat, and mobility fuels

✅ Backed by patents, DOE grants, and licensing deals

 

West Lafayette, Indiana-based Purdue Research Foundation recently completed a licensing agreement with an international energy company – the name of which was not disclosed – for the commercialization of a new process discovered at Purdue University Northwest (PNW) for the biological production of green hydrogen from food waste. A second licensing agreement with a company in Indiana is under negotiation.


Food waste into green hydrogen
Researchers say that this new process, which uses food waste to biologically produce hydrogen, can be used as a clean energy source for producing electricity, as well as for chemical and industrial processes like green steel production or as a transportation fuel.

Robert Kramer, professor of physics at PNW and principal investigator for the research, says that more than 30% of all food, amounting to $48 billion, is wasted in the United States each year. That waste could be used to create hydrogen, a sustainable energy source alongside municipal solid waste power options. When hydrogen is combusted, the only byproduct is water vapor.

The developed process has a high production rate and can be implemented quickly to support large H2 energy systems in practice. The process is robust, reliable, and economically viable for local energy production and processes.

The research team has received five grants from the US Department of Energy and the Purdue Research Foundation totaling around $800,000 over the last eight years to develop the science and technology that led to this process, much like advances in advanced nuclear reactors drive clean energy innovation.

Two patents have been issued, and a third patent is currently in the final stages of approval. Over the next nine months, a scale-up test will be conducted, reflecting how power-to-gas storage can integrate with existing infrastructure. Based upon test results, it is anticipated that construction could start on the first commercial prototype within a year.

Last week, a facility designed to turn non-recyclable plastics into green hydrogen was approved in the UK, as other innovations like the seawater power concept progress globally. It is the second facility of its kind there.

Solar Is Now 33% Cheaper Than Gas Power in US, Guggenheim Says

US Renewable Energy Cost Advantage signals cheaper utility-scale solar and onshore wind versus natural gas, with LCOE declines, tax credits, and climate policy cutting electricity costs for utilities and grids across the United States.

 

Key Points

Cheaper solar and wind than natural gas, driven by LCOE drops, tax credits, and policy, lowering US electricity costs.

✅ Utility-scale solar is about one-third cheaper than gas

✅ Onshore wind costs roughly 44 percent less than natural gas

✅ Policy and tax credits accelerate renewables and cut power prices

 

Natural gas’s dominance as power-plant fuel in the US is fading fast as the cost of electricity generated by US wind and solar projects tumbles and as wind and solar surpass coal in the generation mix, according to Guggenheim Securities.

Utility-scale solar is now about a third cheaper than gas-fired power, while onshore wind is about 44% less expensive, Guggenheim analysts led by Shahriar Pourreza said Monday in a note to clients, a dynamic consistent with falling wholesale power prices in several markets today. 

“Solar and wind now present a deflationary opportunity for electric supply costs,” the analysts said, which “supports the case for economic deployment of renewables across the US,” as the country moves toward 30% wind and solar and one-fourth of total generation in the near term.

Gas prices have surged amid a global supply crunch after Russia’s invasion of Ukraine, while tax-credit extensions and sweeping US climate legislation have brought down the cost of wind and solar, even as renewables surpassed coal in 2022 nationwide. Renewables-heavy utilities like NextEra Energy Inc. and Allete Inc. stand to benefit, and companies that can boost spending on wind and solar, as wind, solar and batteries dominate the 2023 pipeline, will also see faster growth, Guggenheim said.

Is residential solar worth it?

Home Solar Cost vs Utility Bills compares electricity rates, ROI, incentives, and battery storage, explaining payback, financing, and grid fees while highlighting long-term savings, rate volatility, and backup power resilience for homeowners.

 

Key Points

Compares home solar pricing and financing to utility rates, outlining savings, incentives, ROI, and backup power value.

✅ Average retail rates rose 59% in 20 years; volatility persists

✅ Typical 7.15 kW system costs $18,950 before incentives

✅ Federal ITC and state rebates improve ROI and payback

 

When shopping for a home solar system, sometimes the quoted price can leave you wondering why someone would move forward with something that seems so expensive. 

When compared with the status quo, electricity delivered from the utility, the price may not seem so high after all. First, pv magazine will examine the status quo, and how much you can expect to pay for power if you don’t get solar panels. Then, we will examine the average cost of solar arrays today and introduce incentives that boost home solar value.

The cost of doing nothing

Generally, early adopters have financially benefited from going solar by securing price certainty and stemming the impact of steadily increasing utility-bill costs, particularly for energy-insecure households who pay more for electricity.

End-use residential electric customers pay an average of $0.138/kWh in the United States, according to the Energy Information Administration (EIA). In California, that rate is $0.256/kWh, it averages $0.246/kWh across New England, $0.126/kWh in the South Atlantic region, and $0.124/kWh in the Mountain West region.

EIA reports that the average home uses 893 kWh per month, so based on the average retail rate of $0.138/kWh, that’s an electric bill of about $123 monthly, or $229 monthly in California.

Over the last 20 years, EIA data show that retail electricity prices have increased 59% across the United States, with evidence indicating that renewables are not making electricity more expensive, suggesting other factors have driven costs higher, or 2.95% each year.

This means based on historical rates, the average US homeowner can expect to pay $39,460 over the next 20 years on electricity bills. On average, Californians could pay $73,465 over 20 years.

Recent global events show just how unstable prices can be for commodities, and energy is no exception here, with solar panel sales doubling in the UK as homeowners look to cut soaring bills. What will your utility bill cost in 20 years?

These estimated bills also assume that energy use in the home is constant over 20 years, but as the United States electrifies its homes, adds more devices, and adopts electric vehicles, it is fair to expect that many homeowners will use more electricity going forward.

Another factor that may exacerbate rate raising is the upgrade of the national transmission grid. The infrastructure that delivers power to our homes is aging and in need of critical upgrades, and it is estimated that a staggering $500 billion will be spent on transmission buildout by 2035. This half-trillion-dollar cost gets passed down to homeowners in the form of raised utility bill rates.

The benefit of backup power may increase as time goes on as well. Power outages are on the rise across the United States, and recent assessments of the risk of power outages underscore that outages related to severe weather events have doubled in the last 20 years. Climate change-fueled storms are expected to continue to rise, so the role of battery backup in providing reliable energy may increase significantly.

The truth is, we don’t know how much power will cost in 20 years. Though it has increased 59% across the nation in the last 20 years, there is no way to be certain what it will cost going forward. That is where solar has a benefit over the status quo. By purchasing solar, you are securing price certainty going forward, making it easier to budget and plan for the future.

So how do these costs compare to going solar?

Cost of solar

As a general trend, prices for solar have fallen. In 2010, it cost about $40,000 to install a residential solar system, and since then, prices have fallen by as much as 70%, and about 37% in the last five years. However, prices have increased slightly in 2022 due to shipping costs, materials costs, and possible tariffs being placed on imported solar goods, and these pressures aren’t expected to be alleviated in the near-term.

When comparing quotes, the best metric for an apples-to-apples comparison is the cost per watt. Price benchmarking by the National Renewable Energy Laboratory shows the average cost per watt for the nation was $2.65/W DC in 2021, and the average system size was 7.15 kW. So, an average system would cost about $18,950. With 12.5 kWh of battery energy storage, the average cost was $4.26/W, representing an average price tag of $30,460 with batteries included.

The prices above do not include any incentives. Currently, the federal government applies a 26% investment tax credit to the system, bringing down system costs for those who qualify to $14,023 without batteries, and $22,540 with batteries. Compared to the potential $39,460 in utility bills, buying a solar system outright in cash appears to show a clear financial benefit.

Many homeowners will need financing to buy a solar system. Shorter terms can achieve rates as low as 2.99% or less, but financing for a 20-year solar loan typically lands between 5% to 8% or more. Based on 20-year, 7% annual percentage rate terms, a $14,000 system would total about $26,000 in loan payments over 20 years, and the system with batteries included would total about $42,000 in loan payments.

Often when you adopt solar, the utility will still charge you a grid access fee even if your system produces 100% of your needs. These vary from utility to utility but are often around $10 a month. Over 20 years, that equates to about $2,400 that you’ll still need to pay to the utility, plus any costs for energy you use beyond what your system provides.

Based on these average figures, a homeowner could expect to see as much as $12,000 in savings with a 20-year financed system. Homeowners in regions whose retail energy price exceeds the national average could see savings in multiples of that figure.

Though in this example batteries appear to be marginally more expensive than the status quo over a 20-year term, they improve the home by adding the crucial service of backup power, and as battery costs continue to fall they are increasingly being approved to participate in grid services, potentially unlocking additional revenue streams for homeowners.

Another thing to note is most solar systems are warranted for 25 years rather than the 20 used in the status quo example. A panel can last a good 35 years, and though it will begin to produce less in old age, any power produced by a panel you own is money back in your pocket.

Incentives and home value

Many states have additional incentives to boost the value of solar, too, and federal proposals to increase solar generation tenfold could remake the U.S. electricity system. Checking the Database of State Incentives for Renewables (DSIRE) will show the incentives available in your state, and a solar representative should be able to walk you through these benefits when you receive a quote. State incentives change frequently and vary widely, and in some cases are quite rich, offering thousands of dollars in additional benefits.

Another factor to consider is home value. A study by Zillow found that solar arrays increase a home value by 4.1% on average. For a $375,000 home, that’s an increase of $15,375 in value. In most states home solar is exempt from property taxes, making it a great way to boost value without paying taxes for it.

Bottom line

We’ve shared a lot of data on national averages and the potential cost of power going forward, but is solar for you? In the past, early adopters have been rewarded for going solar, and celebrate when they see $0 electric bills paid to the utility company.

Each home is different, each utility is different, and each homeowner has different needs, so evaluating whether solar is right for your home will take a little time and analysis. Representatives from solar companies will walk you through this analysis, and it’s generally a good rule of thumb to get at least three quotes for comparison.

A great resource for starting your research is the Solar Calculator developed by informational site SolarReviews. The calculator offers a quote and savings estimate based on local rates and incentives available to your area. The website also features reviews of installers, equipment, and more.

Some people will save tens of thousands of dollars in the long run with solar, while others may witness more modest savings. Solar will also provide the home clean, local energy, and U.S. solar generation is projected to reach 20% by 2050 as capacity expands, making an impact both on mitigating climate change and in supporting local jobs.

One indisputable benefit of solar is that it will offer greater clarity into what your electricity bills will cost over the next couple of decades, rather than leaving you exposed to whatever rates the utility company decides to charge in the future.
