Enphase Energy
The California company that put a small inverter behind every solar panel instead of one big inverter on the wall, made that "microinverter" the premium standard for US rooftop solar, nearly ran out of money in 2016–17, was rescued by a new CEO (Badri Kothandaraman, from Sep 2017) who rebuilt its costs and margins, and rode the 2019–22 residential boom from ~$316m to ~$2.33bn of revenue and into the S&P 500 (company; index inclusion Jan 2021). Then the channel it sells through — thousands of US and European installers — collapsed in 2023–24 under California's NEM 3.0 (applications from 15 Apr 2023), high interest rates and Europe's post-crisis slump; revenue roughly halved to ~$1.33bn in 2024 (company, Q4 2024 release). A pull-forward before the 25D homeowner credit ended on 31 Dec 2025 lifted 2025 to ~$1.47bn, but by Q3 2026 quarterly revenue was ~$293m and Q4 guidance ~$225–255m (company, 27 Oct 2026). Enphase is the book's case of a premium hardware brand inside a boom-bust installer channel, now trying to sell batteries, commercial products and US-made, 45X-earning hardware into a market tilted toward lease and PPA providers such as Sunrun.
