Tumult in residential solar

Catalyst with Shayle Kann

Residential solar has had a rough couple of years. In 2024, the market contracted 31% and major companies like Sunpower and Titan went bankrupt. Now, only halfway through 2025, Sunnova and Mosaic have filed for bankruptcy, too. The market has suffered from low demand, high interest rates, and major policy changes like California’s cuts to net metering.

So now that the One Big Beautiful Bill phases out key tax credits, what’s next for the battered industry?

In this episode, Shayle talks with Julien Dumoulin-Smith, who leads equity research for power, utilities, and clean energy at Jefferies. Shayle and Julien cover topics like:

Why the IRA eased — but didn’t solve — the troubled market’s key challenges, like high interest rates, tax equity challenges, and intense competition

How debt prevented companies from weathering rising input costs

How the final version of the One Big Beautiful Bill avoided the worst case scenarios for residential solar

Whether the bill will impact utility or residential solar more

How the shift toward leasing will benefit larger companies over small, local installers

The impact of rising electricity prices
