What California is learning from solar panels built over irrigation canals

    It seems like it would be more effective to simply put all the solar panels in a field, and construct a cheap shade over the entire canal no? The supports in the picture are massive and don't look cheap. Also I would imagine the solar array uses more copper than a similar capacity array just built in a field. You can't daisy chain multiple miles of solar panels together, so you need an extra power line to run alongside the whole thing.

    Put the solar panels in a field: The solar array uses less copper. The shade supports don't have to hold up solar panels: Shade supports cost less.

    The best reasoning they give is that California has insane permitting requirements, and it takes 1/6 the time to build on developed land compared to undeveloped land.

      There are solutions like this to most of Californias big intractable problems, and they're not done because some California laws and/or regulations make it impossible.

      This is one reason I now live in Nevada, where pretty much everything is legal...

        A lot of things get easier when everyone basically lives in one city, yes.
