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.

Does the law prescribe that it is the developers who must put it on the buildings?
The measure makes a lot of sense. Solar is available when demand is at the highest. So, it saves on the cost of infrastructure.
A mortgage is the cheapest way to finance (compare to personal low or credit card debt). So, the solar panels earn themselves back quicker. After they have been paid for, they earn more than interest on an equivalent amount of money. It makes financial sense if you look ahead. That, of course, is not everybody's cup of tea so I like the law.
All of the above advantages, and I haven't made mention of the environment, depletion of fossil resources and AGW.
