๐ Energy Generation Cluster: Plug-in Solar 101, Live Demo, & Deep Dive Q&A
โIn Germany, more than a million households make their own electricity from a few panels on a balcony, a fence, or a deck. No roof, no electrician, no permit. You just plug it into an outlet.
โBut in California, that is still not legal. On August 25, SB 868, the Plug and Play Solar Act, passed the California Assembly and Governor Newsom has until September 30 to sign it. Learn about this crucial climate tool and where it stands today.
โBright Saver co-founder Rupert Mayer will demo and walk through what plug-in solar actually is, what it costs, and where the technology stands today. He will take the misconceptions head on: whether it backfeeds dangerously into the grid, whether it needs a permit or an electrician, whether the savings are real, and why the US is a decade behind Europe on a product that starts around $300.
โWe'll cover California specifics, what SB 868 does and does not allow, the 1,200 watt cap, what happens next, and what actually changes for households if the law is passed.
