California became the first state in the nation to require homes built in 2020 and later be solar powered, following a vote by the Building Standards Commission.
The unanimous action on Wednesday finalizes a previous vote by the Energy Commission and fulfills a decade-old goal to make the state reliant on cleaner energy.
“These provisions really are historic and will be a beacon of light for the rest of the country,” said Kent Sasaki, a structural engineer and one of six building standards commissioners. “(It’s) the beginning of substantial improvement in how we produce energy and reduce the consumption of fossil fuels.”
California moves to require solar panels on all new homes
While nobody spoke Wednesday in opposition, the commission received about 300 letters opposing the mandate because of the added cost, the Orange County Register reported.
Energy officials estimated the provisions will add $10,000 to the cost of building a single-family home — about $8,400 from adding solar and about $1,500 for making homes more energy-efficient. But those costs would be offset by lower utility bills over the 30-year lifespan of the solar panels, officials said.
