Why 4 in 10 Americans Are Quietly Walking Away From Solar Panels

Something unexpected is happening on America’s rooftops. After years of breakneck growth and soaring enthusiasm, a significant portion of American homeowners are quietly stepping back from solar panels. The residential solar industry in the United States experienced one of its most difficult years in recent memory in 2024, as installations nationwide declined 31% compared to 2023. This isn’t just a temporary blip. It reflects a convergence of financial pressure, policy reversals, industry instability, and growing awareness gaps that are pushing roughly 4 in 10 Americans away from a technology that once seemed like a no-brainer.

A Sharp and Unexpected Decline in Demand

The 4.7 GW installed in 2024 marked the first annual contraction of the residential solar industry since 2017. Last year was predicted to be a year of recovery off the slowed growth of 2023, but challenges persisted. That’s not the kind of headline the solar industry was hoping for. Chief among those challenges were higher-for-longer interest rates, state policy changes like cuts to net metering in California, and stabilizing natural gas and electricity prices.

While more than 4.8 million American households now have solar panels, policy changes contributed to a projected 26% drop in installations nationwide in 2024. During the first half of the year, residential solar installations declined in 41 states, signaling that 2024 would likely be a slower year for solar growth. The numbers paint a clear picture: interest in solar didn’t evaporate overnight, but meaningful barriers are causing homeowners to pause, reconsider, or walk away entirely. Among those who say they are not likely to consider installing solar, the upfront cost is the biggest obstacle, with 39% of respondents citing it as their main reason for not pursuing rooftop solar.

Net Metering Cuts Are Rewriting the Math

For years, net metering was the financial engine that made residential solar genuinely attractive. It allowed homeowners to sell surplus electricity back to the grid at retail rates, slashing their bills significantly. That engine is now sputtering in state after state. In 2023, California changed its net metering policy to something called net billing, also known as NEM 3.0, making solar a much less compelling offer to homeowners. California leads the country in rooftop solar, so this shift sent shockwaves well beyond its borders.

The NC Clean Energy Technology Center found that 47 states, plus the District of Columbia and Puerto Rico, took some type of distributed solar policy action during 2024. The greatest number of actions were related to net metering policies, residential fixed charge increases, and community solar. About one-third of the states are either offering alternatives to traditional net metering or making significant revisions. What that means in plain terms is that the financial returns homeowners were promised when they signed their contracts are being quietly reduced. California’s new net billing tariff pays roughly 75% less for solar power sent back to the grid than the legacy net-metering program.

A Wave of Solar Company Bankruptcies Is Shaking Consumer Trust

Beyond policy changes, the solar industry has been rocked by a startling wave of business failures that have left ordinary homeowners in an uncomfortable position. Some of the biggest and most recent U.S. cases include major residential brands and financing platforms entering bankruptcy or shutting down between 2024 and 2025, including SunPower, Titan Solar Power, Sunnova, and Mosaic. These aren’t small operators. They were some of the most recognized names in residential solar. SunPower, which started as a pioneering manufacturer of high-performance solar panels and grew into one of the nation’s top solar companies, filed for Chapter 11 bankruptcy protection on August 5, 2024. The company weathered multiple recessions, a public IPO, and international acquisitions, but ultimately crashed into the rocks in 2024.

The past two years have been brutal for the U.S. solar industry, with over 100 companies filing for bankruptcy or ceasing operations, an unprecedented figure in nearly two decades of solar market growth. The fallout is deeply personal for homeowners. Homeowners are left with non-functional systems, voided warranties, and ongoing loan payments for equipment that doesn’t work. Thousands of homeowners are left without repair services or support for systems installed by solar companies that later went bankrupt. California alone has over 820,000 abandoned installations, according to Solar Insure data. Many residential installers have expressed that the recent closures of large companies like SunPower have caused potential customers to become more wary of all solar companies.

The Tax Credit Window Is Closing and Awareness Remains Low

One of the most powerful incentives for going solar has been the federal Investment Tax Credit, which offers homeowners a meaningful reduction on their installation costs. That window is now dramatically narrower than most people realize. Federal and state incentives have made installing solar panels a fairly affordable home improvement project. But new federal legislation has accelerated the expiration of the 30% tax credit for homeowner-owned solar systems, moved the deadline up by seven years to the end of 2025. Starting in 2026, the same system that previously qualified for the credit costs about $28,000 if the tax credit expires.

Yet despite the urgency, public awareness of available incentives remains surprisingly thin. While existing tax credits at the federal, state, and local levels can help reduce costs, only 34% of respondents say they are aware of such incentives in their state, highlighting the need for increased education and outreach. The total proportion of home solar installations that include extra services has regressed since 2023, indicating that homeowners could be less willing to spend money on add-on items like energy storage, oversized solar systems, and related upgrades. Wood Mackenzie downgraded its outlook for residential solar, cutting its growth forecast by 15% in 2025. The shrinking incentive window, combined with low awareness and a bruised industry reputation, is creating exactly the kind of hesitation that causes people to simply walk away.
