Why is USA Residential Solar So Expensive? The Real Reason U.S. Solar Is So Expensive #344

Solar modules once cost $8 per watt. Geoff Greenfield bought his first panels from a classified ad in Home Power magazine. Twenty-six years later, he leads an EPC division building 67 MW projects and negotiating 100 MW contracts.In this episode of The Clean Power Hour, host Tim Montague sits down with Greenfield to trace the full arc of the U.S. solar industry, from off-grid battery systems with lead-acid batteries to utility-scale construction backed by a multi-billion-dollar general contractor. They cover NABCEP's role in professional standards, why U.S. residential solar costs two to three times more than in Australia or Germany, and why the industry needs to prepare for a future without tax credits.EPISODE HIGHLIGHTSStarting a solar company in 2000 meant buying used 53-watt panels from classified ads at $6 per watt. Greenfield traces how the economics shifted from pure environmental motivation to grid parity and beyond.NABCEP credentials go beyond technical competence. Organizations have lost certification over ethical violations, and state attorneys general are now pursuing solar bad actors.Panel efficiency is approaching physical limits, but economic efficiency still has room.In PJM territory, commercial battery storage pays for itself through peaking value and ancillary services, sometimes faster than solar alone. Resilience sells in residential, but the commercial case depends on grid services math.The solar tax credit is likely not returning. Companies preparing for 2028 and beyond are cutting soft costs, joining procurement cooperatives like Amicus Solar, and building business models that work without incentives.This conversation provides a 26-year field perspective on what it took to grow from a one-person off-grid installer to a utility-scale EPC, and what comes next for companies facing the same transition.Connect with Geoff Greenfield, Kokosing Geoff LinkedIn: https://www.linkedin.com/in/geoff-greenfield-595a406/Kokosing Website: https://kokosingsolar.com/ Support the showConnect with Tim  Clean Power Hour  Clean Power Hour on YouTubeTim on TwitterTim on LinkedIn Email [email protected] Review Clean Power Hour on Apple PodcastsThe Clean Power Hour is produced by the Clean Power Consulting Group and created by Tim Montague.
