What is Plugin Solar?
Also known as Balcony Solar — small solar systems designed to plug straight into a standard outlet. No roof work, no grid work, just sunshine and a power strip.
Plugs into a standard outlet
A compact solar system built to connect to the wall socket you already have — sized to work with typical household wiring.
DIY installation
No permits, no electrician, no professional required. Mount it on a balcony, railing, or wall, plug in, done.
Battery-ready
Offsets your limited daytime usage; paired with a battery, it can offset peak usage and provide limited backup power during outages.
Renter friendly
Often allowed in apartments and rentals — and when you move, you pack it up and take it with you.
Why now?
Balcony solar has been legal and popular across Europe for years. The US is finally catching up — and California just drew first blood.
