California to require new homes to have solar in 2020...

I admit I haven't checked on the rules and methods of this, and I applaud the idea....

...but some houses and locations have such a poor layout for solar this doesn't make any sense to me.

I know when I was looking for a lot in our park for good solar access only 1 in 40 had reasonable solar access with cutting trees on neighboring lots and only about 40 in 1500 were reasonable well setup from the get-go!

I would guess this will have to be over turned or have some measure of setting this aside for those communities that values trees.

- Assorted other systems, pieces and to many panels in the closet to not do more projects.

    I think the rules are solar gt only if the house and lot makes sense. Buildings and landscaping that block the sun exempt the home.

    Years ago, there was a good sized development that was going 100% gt solar, but that would have required a new distribution substation (more or less, gt solar has 3 to 4x the peak average power back fed into the grid vs the average peak loads. They dropped the project.

    That will drive up the prices of both buying and renting in Cali. Its a government mandate and that usually ends very poorly.
