Solar power is now among the cheapest forms of electricity on Earth. Yet the industry still behaves as if it can’t survive without government support.
Since President Donald Trump signed the “One Big Beautiful Bill” last July 4, the solar industry has sounded alarms.
The law ended the residential solar tax credit immediately and set a firm deadline—this coming July 4—for commercial and utility-scale developers to begin construction if they want to qualify for the remaining 30% Investment Tax Credit. Industry groups have warned of collapse. Lobbyists have flooded Capitol Hill. Obituaries for America’s solar industry are already being drafted.
They’re premature.
The solar industry doesn’t have a subsidy problem. It has a confidence problem. July 4 isn’t a deadline to fear but a milestone that signals American solar is ready to compete without training wheels.
The numbers tell the story. According to the International Renewable Energy Agency, the cost of utility-scale solar has fallen roughly 90% since 2010—from about 46 cents per kilowatt-hour to roughly 4.3 cents today. Solar is now one of the cheapest sources of new electricity generation in the world, trailing only onshore wind. Over the past decade the industry has grown at an average annual rate of about 28%.
The U.S. now has roughly 262 gigawatts of installed solar capacity—enough to power about 45 million homes, according to the Solar Energy Industries Association.
Demand for electricity is also rising quickly. Data centers, the reshoring of manufacturing, and electrification across the economy are creating the largest sustained expansion of American power demand in a generation. Solar is one of the fastest and least expensive ways to meet much of that need, and that advantage doesn’t disappear on July 5.

All of this means solar is no longer a fragile startup industry. It is one of the most remarkable energy scale-ups in modern American history. The industry simply hasn’t fully accepted that reality.
Solar companies continue to push for the return of tax credits largely because those credits once worked. Two decades ago solar panels were expensive, financing was scarce, and the economics of large projects were uncertain. The Investment Tax Credit gave developers the margin they needed to take risks markets weren’t yet ready to support.
Much like early government incentives helped launch industries ranging from advanced nuclear to biotechnology and aerospace, targeted support helped get American solar off the ground. It bridged the gap between promising technology and a self-sustaining market.
But subsidies are supposed to phase out when industries mature. Solar’s tax credit regime never quite got that memo.
Instead of fading as solar became cost-competitive, the subsidies persisted—and their structure began quietly working against the industry they were meant to help. Because the credit was calculated as a percentage of total project cost, developers were rewarded for how much they spent rather than how efficiently they produced electricity.

Analysis by Resources for the Future suggests investment-based credits such as the ITC can steer projects toward higher capital spending rather than operational efficiency, raising total system costs.
Recent bankruptcies tell part of that story. In 2024 SunPower filed for bankruptcy despite billions in federal subsidies flowing through the industry. Dozens of other companies failed in 2024 and 2025. Subsidies didn’t save them; in many cases they simply prolonged flawed business models.
There has also been a geopolitical cost. Much of the global decline in solar prices has been driven by China’s manufacturing dominance. Today China controls more than 80% of global solar panel production and most key upstream supply chains, according to the International Energy Agency report on Solar PV Supply Chains.
The Investment Tax Credit accelerated America’s dependence on that system. By rewarding rapid deployment, it encouraged developers to buy panels from whichever suppliers could ship fastest and cheapest—often Chinese manufacturers.
The result has been two decades of building American energy infrastructure with components largely produced by a strategic competitor.
The new law attempts to correct that imbalance by tightening limits on components from Chinese-controlled supply chains. Critics argue that ending subsidies while restricting Chinese inputs will devastate the industry. In reality, it may provide a long overdue stress test.
Costs may rise temporarily as supply chains shift and domestic manufacturing scales up. But the long-term result could be a solar sector driven by innovation and competition rather than subsidy optimization.
After decades of public support, policymakers aren’t sending the solar industry to its funeral.
They’re celebrating its graduation.
