One Sentence in the House Megabill Will Destroy the Rooftop Solar Model

A loophole created by the House Ways and Means text disappeared in the final bill.

Early this morning, the House of Representatives launched a full-frontal assault on the residential solar business model. The new language in the budget reconciliation bill to extend the Tax Cuts and Jobs Act passed Thursday included even tighter restrictions on the tech-neutral investment tax credits claimed by businesses like Sunrun when they lease solar systems to residential buyers.

While the earlier language from the Ways and Means committee eliminated the 25D tax credit for those who purchased home solar systems after the end of this year (it was originally supposed to run through 2034), the new language says that no credit “shall be allowed under this section for any investment during the taxable year” (emphasis mine) if the entity claiming the tax credit “rents or leases such property to a third party during such taxable year” and “the lessee would qualify for a credit under section 25D with respect to such property if the lessee owned such property.”

This is how you kill a business model in legislative text.

“Expect shares of solar companies to take a significant step back,” Jefferies analyst Julien Dumoulin-Smith wrote in a note to clients Thursday morning, calling the exclusion “scathing.” Investors are “losing the now false sense of security that we had 'seen the worst' of it with the initial House draft.”

Joseph Osha, an analyst for Guggenheim, agrees. “Considering the fact that ~70% of the residential solar industry is now supported by third-party (e.g. lease or PPA) financing arrangements, the new language is disastrous for the residential solar industry,” he wrote in a note to clients. “We believe the near-term implications are very negative for Sunrun, Enphase, and SolarEdge.”

Shares of Sunrun are down 37.5% in mid-day trading, wiping off almost $1 billion worth of value for its shareholders. The company did not respond to a request for comment. Shares of fellow residential solar inverter and systems Enphase are down 20%, while residential solar technology company SolarEdge’s shares are down 24.5%.

“Families will lose the freedom to control their energy costs,” Abigail Ross Hopper, chief executive of the Solar Energy Industries Association, said in a statement, in reference to the last-minute alteration to the investment tax credit.

When the House Ways and Means Committee released the initial language getting rid of 25D by the end of this year but keeping a limited version of the investment tax credit, analysts noted that Sunrun was an unexpected winner from the bill. It typically markets its solar products as leases or power purchase agreements, not outright sales of the system.

The reversal, Dumoulin-Smith wrote, “comes as a surprise especially considering how favorable the initial markup was” to the Sunrun business model.

“Our core solar service offerings are provided through our lease and power purchase agreements,” the company said in its 2024 annual report. “While customers have the option to purchase a solar energy system outright from us, most of our customers choose to buy solar as a service from us through our Customer Agreements without the significant upfront investment of purchasing a solar energy system.”

The new bill, Dumoulin-Smith writes is “‘leveling the playing field’ by targeting all future residential solar originations, whether leased or owned.” The bill is “negative to Sunrun with intentional targeting of the sector.

Last year, Sunrun generated over $700 million from transferring investment tax credits from its solar and storage projects. The company said that it had $117 million of “incentives revenue” in 2024, which includes the tax credits, out of around $1.4 billion in total revenue.

But the tax credits play a far larger role in the business than just how they’re recognized on the company’s earnings statements. The company raises investment funds to help finance the projects, where investors get payments from customers as well as monetized tax credits. Fund investors “can receive attractive after-tax returns from our investment funds due to their ability to utilize Commercial ITCs,” the company said in its report. Conversely, the financing “enables us to offer attractive pricing to our customers for the energy generated by the solar energy system on their homes.”

Morgan Stanley analyst Andrew Perocco wrote to clients that “this is a noteworthy change for the residential solar industry, and Sunrun in particular, which dominates the residential solar [third-party owned] market and has recognized ITC credits under 48E.”

Brace Yourselves for Snaptember

The Pacific Northwest fire season is about to get even worse.

I turned on the heat this week for the first time since spring. Tuesday started out mild, damp, and overcast here in Seattle — the kind of weather the city still conjures in the popular imagination, even if about 50 days a year now are warmer than they used to be because of climate change. Summers here may be getting longer, but this morning felt truly like fall, and in the uninsulated shed where I do most of my writing, I briefly turned on the space heater to stave off the nip.

The same slow-moving low-pressure system responsible for the moody weather in the Puget Sound region will also go far in curbing the state’s wildfires, per Tuesday’s update to the National Wildland Significant Fire Potential Outlook. It’s almost obscenely good luck: September is historically one of the worst times of year for wildfire in the Pacific Northwest, after the summer’s high temperatures have dried out all the fuels but before the autumn rains arrive.

1. New U.S. strikes on Iran spike oil prices

Oil prices surged north of $90 per barrel Tuesday as the United States exchanged fire with Iran amid the ongoing fight to control the Strait of Hormuz. West Texas Intermediate, the U.S. benchmark, rose nearly 2% to $91.74 per barrel. Europe’s Brent crude measure closed less than 2% higher at just below $97. Murban crude, the yardstick for oil out of Abu Dhabi, soared nearly 8% to over $106 per barrel. In a post on Truth Social, President Donald Trump said he was “not trying to force Iran to the bargaining table.” Rather, “I couldn’t care less if they sign a worthless, to them, agreement,” he continued. “I like our position now much better, with almost total control of the Hormuz Strait, and their economy totally collapsing.” Referring to the U.S. military as the “American terrorists,” the Tasnim News Agency, a semi-official outlet associated with Iran’s Islamic Revolutionary Guard Corps, reported that Tehran “had previously warned and promised” that “the Iranian armed forces will respond decisively and extensively to any aggression against our country’s territory and interests.”
