Right now, about one in five new homes in California comes with solar panels already installed. In two years, it will be all of them.
On Wednesday, California Energy Commission's vote was unanimous: California will soon become the first state to require solar panels on all new homes and on residential buildings smaller than four stories.
The law, which takes effect Jan. 1, 2020, specifies the minimum size of the system would be based on the size of the building and can vary between 2 and 7 kilowatts of output per dwelling.

> how to value engineer a solar panel to fail rapidly

While that won't bother those who build crap before declaring bankruptcy every two years, those who rely on name recognition will demand trouble-free roof materials.
