What Is Plug-In Solar?
Plug-in solar — also called balcony solar or plug-and-play solar — is a small integrated solar setup that sends power into your home through a standard outlet, reducing how much electricity you buy from the utility during the day. It’s especially popular as renter-friendly solar for apartments, condos, and any home without roof access. In the US, the safe versions use certified microinverters and follow rules such as UL 3700 and NEC 705.
