Over the last two decades, more than 5 million U.S. households, stretching from California to Georgia and Maine, have installed solar panels on their rooftops, harnessing solar energy and cutting down on electricity costs.
However, this progress may be abruptly halted.
A recent domestic policy bill approved by House Republicans aims to cut tax incentives for homeowners and solar leasing companies, which have significantly contributed to the rise in rooftop solar adoption, by the end of this year. Analysts and industry experts warn that if this legislation is enacted, it would result in an immediate slowdown in installations.
Ben Airth, policy director at Freedom Forever, one of the largest residential solar installers in the country, stated, “This is setting us back.” He remembers a time when solar installations were primarily undertaken by wealthy environmentalists preparing for retirement.
According to an analysis from energy data firm Ohm Analysis, residential solar installations could decline by 50% next year if the House bill is enacted. Without tax credits, homeowners would take an average of 17 years to recoup their solar investments. A more pessimistic forecast from Morgan Stanley predicts an 85% decrease in rooftop solar demand by 2030.
Republicans also seek to limit tax breaks for other renewable energy technologies, such as wind turbines and large solar farms, but the repercussions for rooftop solar could prove to be even more drastic. Rooftop solar costs 2-3 times more per unit of power than large solar arrays installed on agricultural land and in deserts, making the residential sector more susceptible to subsidy alterations.
The Senate is currently drafting its version of the domestic policy bill, while solar industry executives are lobbying in Washington for more progressive energy credit initiatives. They emphasize that the solar sector currently employs around 300,000 workers and that rooftop systems significantly reduce homeowners’ electricity expenses.
Nonetheless, some conservative Republicans are explicitly opposed to any restoration of renewable energy tax incentives.
Texas Republican Chip Roy criticized, stating, “We’re devastating our energy infrastructure, wrecking our grid, ruining our landscapes, and compromising our freedoms.” He added, “I don’t support that.”
The existing uncertainty is jeopardizing an industry that is already grappling with high tariffs and soaring interest rates. Last week, Solar Mosaic announced it would provide loans for homeowners to install rooftop panels, following its bankruptcy declaration. Recently, Sunnova Energy, one of the largest rooftop solar providers in the U.S., followed suit.
Experts suggest that even if rooftop solar ultimately becomes unsubsidized, rising electricity prices nationwide could still make solar energy more financially appealing. Nevertheless, the transition may be challenging, likely resulting in increased bankruptcies and layoffs.
Zoe Gaston, a leading analyst for residential solar at Wood Mackenzie, mentioned, “But that market will inevitably be smaller.”
Significant Tax Revisions
For the past 20 years, Congress has provided tax credits for the installation of solar panels on rooftops. However, these subsidies faced major reductions through the 2022 Inflation Reduction Act, which allocated hundreds of billions of dollars toward technology aimed at tackling climate change.
The legislation has extended the residential solar credit, allowing homeowners to recoup 30% of their solar system costs until 2032. It has also broadened the Investment Tax Credit for businesses constructing low-emission power sources like solar and battery technologies.
These changes have led to a surge in solar leases, allowing homeowners to avoid upfront costs for rooftop systems that can exceed $30,000. Instead, the solar company owns the panels and applies for tax credits, while homeowners lease the equipment and ideally save money through lower utility bills.
Currently, over 50% of residential solar systems are financed in this manner, making rooftop solar more attainable for schools, hospitals, and small businesses.
The House Republican bill seeks to eliminate the solar tax credit for residential properties by the end of 2025, meaning immediate qualification for investment tax credits will not be permitted.
Moreover, the House bill forbids businesses from claiming tax credits if they utilize components sourced from China, which dominates the solar supply chain. Many companies have expressed that the legislation is written so broadly that it would inhibit their ability to claim credits effectively.
Gregg Felton, CEO of Altus Power, which develops solar projects for rooftops and parking lots, remarked that the House bill “adequately represents the industry’s impact.”
If Congress significantly cuts support for renewable energy, experts predict that companies will still invest in large solar arrays, as they frequently represent one of the most cost-effective methods to increase energy generation, even without subsidies. Conversely, rooftop solar remains more expensive, requires more labor, and carries greater risks.
Kenny Plannenstiel, COO of Big Dog Solar, an Idaho-based installation firm, noted that rooftop solar has gained traction in emerging markets like Montana and Idaho.
“There is substantial interest among those wanting to take control of their energy future, as well as among those concerned about grid reliability,” Pfannenstiel added. With the tax credit in place, “the financial argument for these customers installing solar and battery systems has become much stronger,” he explained.
If the credits disappear, some customers may still desire solar panels, Pfannenstiel noted, but the market will “shrink significantly.”
The repercussions could be far-reaching. If a solar leasing company goes under, there may be no one left to service the solar panels, resulting in job losses for thousands of installers and electricians.
In recent years, over 30 solar plants have commenced operations in the U.S., but a slowdown in demand could lead to their closure.
Freedom Forever, a California-based solar installer, noted that two years ago, none of their components were sourced from the U.S.; now, approximately 85% are, including inverters manufactured in Texas and Florida. This shift is driven by the Inflation Reduction Act, which provided extra credits for utilizing domestic components.
Without these credits, Airth cautioned, “the industry will revert to relying on the lowest-cost components, often produced overseas.”
Debates Over Rooftop Solar
The fight for tax credits in Congress is not the sole hurdle for rooftop solar. While the technology remains favored by homeowners, certain states are starting to retract support amidst considerable backlash.
Electric utilities and some analysts argue that rooftop solar users increase costs for everyone else, as solar households pay lower monthly utility bills but depend on the grid for backup power. This shifts the cost of grid maintenance onto other households, often those with lower incomes. (Supporters of solar disagree, claiming utilities overlook the many benefits of rooftop installations, such as avoided transmission expenses.)
The conflict has been particularly intense in California, the nation’s leading rooftop solar market. In 2022, regulators significantly decreased the compensation that new solar households could receive for the electricity they generate. As a result, rooftop installations plummeted by 85% statewide, affecting installers, manufacturers, and distributors.
Currently, some officials advocate for a reassessment of the existing solar grant program’s impact on Californians who may not afford solar panel systems, as stated by Democratic state legislator Lisa Calderon.
Rising interest rates have further complicated the affordability of rooftop solar systems, making it costlier to secure funding for new equipment. Additionally, both the Trump and Biden administrations have imposed increased tariffs on solar products from China.
Some stakeholders within the rooftop solar sector argue they have to focus on cost-cutting measures.
Not only is rooftop solar pricier than large utility-scale solar farms, but the price of a U.S. home solar installation is three times that of a similar system in Australia. Some analysts attribute the difference to the regulatory challenges.
“Eventually, our industry may function without tax credits,” stated Chris Hopper, co-founder of Aurora Solar, a software company specializing in home solar systems. “I believe we can navigate these credit phase-downs over a reasonable timeframe.
“However, sudden changes would be devastating,” Hopper emphasized. “Rapid adaptation is simply not feasible.”
