A single design error on a commercial solar project can cost $60,000 to $70,000 to fix. Scott Wyssling and Catherine Kelso of Wyssling Consulting explain what quality design actually looks like, why AI cannot replace a licensed engineer reviewing plans, and how battery integration really fits into commercial solar today. In this episode, Tim Montague…

Battery energy storage fire safety is one of the most urgent permitting challenges facing solar and storage developers in 2026. Mike Nicholas, Energy Storage Specialist and Fire Consultant at Hiller Companies, brings a rare perspective: he built Kern County’s entire BESS permitting program from scratch in 2019, when no national standards existed, and now travels…

A US federal court just ruled the IRS acted in an “arbitrary and capricious” manner on solar and wind safe harbor rules, shaking up project timelines for developers racing toward the July 4, 2026 deadline.  Meanwhile, at the Shanghai Solar Show (SNEC), energy storage claimed more floor space than solar panels for the first time,…

Solar & storage pioneers Solar Design Associates share 50 years of firsts on the Clean Power Hour. They put solar on the White House in 1979 and built the first community solar garden in America. Haskell Werlin and Steven Strong trace solar’s fall from $16 to $1 per watt, explain why the battery cost curve…

Community microgrids and virtual power plants are two of the most misunderstood concepts in clean energy, and the gap between them is where billions of dollars in grid value are being left on the table. Craig Lewis, Founder and CEO of the Clean Coalition, returns to The Clean Power Hour to break down how community-scale…

Energy resilience for homeowners is the mission behind Energy Access Innovations, a multi-brand clean energy company building an end-to-end ecosystem for solar and battery storage. Nicole Tomasin, Chief Commercial Officer at EAI, joins Tim Montague to explain how the company serves the consumers the rest of the industry ignores, including DIYers and rural markets. Battery…

Silicon solar is approaching a hard physical efficiency ceiling at 30%. Perovskite tandem solar is the only proven path through it. Joel Jean, CEO of Swift Solar, explains the technology, what the Meyer Burger acquisition brings, and where tandems sit on the road to commercial scale. After seven decades, silicon solar is closing in on…

A new report from Clean Energy Associates found that some solar module factories in their first year of production are hitting yield rates as low as 30%. That means 70% of modules coming off certain lines require rework before they ship. The finding applies directly to US manufacturers, most of which are still in early…

Community microgrids are functionally illegal in most of the United States, yet climate-driven outages are getting worse. Cameron Brooks of Think Microgrid explains why wires laws block resilient grid solutions and what it costs us to keep burying lines instead. Burying power lines costs $4 million per mile in Colorado and up to $9 million…
