Solar carport installation costs can swing by 12 cents per watt before a single panel goes up. Kyle Sinclair, CEO and co-founder of SDE (Sinclair Designs and Engineering), James Strizki, Project Manager and CFO of GenMounts and Renewable Energy Holdings, and Matt Boyce, a PE licensed in 27 states and Principal Engineer at Engineered Solutions,…

CATL unveiled its TENER Sodium energy storage system at Intersolar Europe in Munich, rated for 15,000 cycles to 70 percent state of health at room temperature. CATL frames that as a 25 to 30 year service life, and it takes only 34 modules to stand up a one gigawatt-hour site. That single specification changes how…

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…
