Enphase makes small solar power devices that turn sunlight into usable home electricity and software to manage it.
Enphase Energy sells the little box that turns the sun's electricity into something your house can actually use. That box is called a microinverter, and it clips onto the back of each individual solar panel. The company also sells batteries you hang on your wall to store extra power, plus software that lets you watch and control it all from your phone. Most of its money comes from selling hardware to homeowners, and it gets there by selling through a network of installers who put panels on roofs — people who already decided they want solar, then pick Enphase because its gear is reliable and easy to monitor panel by panel.
The business runs on two connected parts. The bigger part is the microinverters, which is most of revenue. The smaller but fast-growing part is batteries and the app-style software around them, so a home can keep the lights on at night or during a blackout. Recently Enphase has been pushing into newer markets like Europe and India, and it started making home batteries designed to work with its own system so customers stay in its ecosystem. It also has been dealing with a real problem: high interest rates and slower U.S. rooftop solar sales have squeezed demand, and competition from cheaper rivals has pushed prices down. That is why its stock and sales have bounced around a lot lately.
Think of it as the iPhone of a solar roof — the panel catches the sunlight, but Enphase's box and app are what make the whole thing smart and usable. The company was founded in 2006 and is based in Fremont, California, in the heart of Silicon Valley. It makes money when homeowners and installers buy its microinverters and batteries, and it keeps a chunk of cash to buy back its own stock, which shrinks the number of shares and can lift the value of the ones left. The big question for Enphase is simple: can it sell more batteries and win back growth as solar gets cheaper and more homes go electric?
