States weigh bills to allow plug-in solar systems

Legislators in 24 states are considering bills to allow small plug-in solar systems that connect directly into a wall socket. Utah became the first state after a unanimous vote last year; these systems retail for about $2,000 and produce enough electricity to power a laptop or a small refrigerator.

Bills in the other states would generally allow homeowners and renters to install plug-in panels, often up to 1,200 watts, without local utility approval. Backers point to low cost and simple installation—no electrician in many cases—and say the devices are far cheaper than rooftop arrays, which average around $20,000, making them attractive as household electricity bills rise.

Proponents also hope the measures will speed development of safety certification. UL Solutions released preliminary criteria in December, and the company’s vice president, Ken Boyce, said some proposals call for additional electrical work to protect wiring from potential fires or shocks.
