California Legalizes Balcony Solar Installations Up To 1,200W Starting 2027
Key points
- California legalized balcony solar installations up to 1,200W.
- The Plug and Play Solar Act takes effect January 1, 2027.
- Installations require UL3700 certification for safety.
- No utility registration is needed for these systems.
New Law for Balcony Solar
California has enacted the Plug and Play Solar Act, making plug-in solar installations, also known as balcony solar, legal. Governor Gavin Newsom signed the bill into law on September 30th, with an effective date of January 1, 2027. This legislation aims to provide energy cost relief for residents, including renters.
Installation Details and Limitations
The new law permits installations up to 1,200W, which is sufficient to power a refrigerator and several small appliances. This wattage limit aligns with most other states, though it is less than Colorado's 1,920W maximum. Unlike rooftop solar, these systems will not require registration with utility companies, simplifying the approval process.
Certification Requirements
A key requirement for balcony solar systems in California is UL or equivalent certification, specifically UL3700. This certification ensures safety features such as protection against electrical hazards, overloads, and incorrect current flow. The UL3700 standard mandates a "uniquely configured, non-NEMA plug and receptacle system," which may necessitate an electrician for some installations despite the "plug-and-play" designation.
Market and Future Outlook
Currently, only a few products from companies like Hoymiles and APsystems are certified under UL3700. The requirement for a specialized plug system could impact the ease of installation for renters. However, future product innovations are anticipated to make these systems more accessible and truly plug-and-play.
