Everyone likes rooftop solar in theory. Panels keep getting cheaper, and the tax break on them is real.
So why does the U.S. home-solar market feel stuck? Shuki Nir, the CEO of SolarEdge, has a short answer: money.
He said financing problems are the root cause of the sluggish U.S. home-solar market. His comments came in a report released at 3:02 p.m. Eastern time on August 5, 2026.
That answer carries weight because SolarEdge is an equipment supplier whose sales depend on installers' ability to finance their projects. Installers need cash to buy gear, and that cash is tied to tax-equity financing. So when lending goes cold, the company's customers are directly affected.
Lenders will not put that cash to work unless they trust the tax breaks behind the deal.
Installers across the country are caught in the middle. They pitch the panels, handle the paperwork, and then scramble to line up financing while the rules are up in the air.
The weak link right now is the federal tax credit for rooftop solar equipment. The rules around it are unsettled, and that makes life difficult for everyone in the chain.
Installers are having a harder time raising money because lenders cannot tell what the tax break will be worth.
Financiers who invest in tax equity, the money put into solar projects in exchange for the tax benefits, are waiting on new U.S. Treasury guidance.
The Treasury's new rules are designed to keep Chinese and other barred foreign parties from receiving U.S. clean-energy incentives.
Think of tax credits as the fuel for the whole system. When the fuel is uncertain, everyone from the bank to the installer to the homeowner hits the brakes.

Because that risk has grown, investors are demanding bigger returns, and solar leasing becomes less financially viable as a result.
Leasing is how many homeowners avoid a giant upfront bill, so when leasing math gets worse, demand for panels cools.
Homeowners feel the shift too. If you are not sure what your tax credit will be worth down the road, it is hard to sign a long-term lease.
The uncertainty alone is enough to make people hit pause.
Nir expects the pause to end. After the Treasury finalizes the guidance, he says, the market should spring back.
"The belief is that once this clarification is finalized, we will see a rebound in the market," CEO says.
Investors seemed to like the message. SolarEdge was trading at $34.93.
The stock was up 28.36%.
JPMorgan Chase sat at $359.93.
That was up just 0.67%, a sign this was a solar story rather than a whole-market story.
The big lesson is that solar stocks are policy stocks right now. A single comment from a CEO about Treasury guidance can move a share price sharply in a day, and that cuts both ways.
When the rules finally land, expect more movement. The direction depends on what the guidance says and whether it makes financiers comfortable enough to put money back to work.
For anyone watching the home-solar market, whether as an investor or as a homeowner, the takeaway is simple.
The technology is not the problem. The market is stuck on a rule that Washington has not finished yet.
That gives the slump a clear cause, and the cause has a clear fix.
The companies caught in the slump are not dealing with a broken product or a fading fad. They are dealing with a rule that is stuck in Washington.
Once Washington finishes the job, the pieces that make rooftop solar work should click back together.
The panels are fine. The paperwork just needs to catch up.
