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.

      Anecdotally speaking, I have heard of a massive California solar farm in an undeveloped area that has serious vandalism problems. Junkies will find ways through the fencing at night, strip copper and other materials from panels, and cause thousands in damages and lost energy just to extract enough scrap for a fix.

      Nothing short of a face-to-face security response will deter these criminals, so there it is a challenging cost-benefit balance. At least panels in parking lots and other developed spaces have the benefit of witnesses. I'm sure a 20 foot climb up a steel beam over running water is a decent deterrent as well.

        I’m willing to bet if we gave them their fix they wouldn’t steal a thing. But because their fix is illegal they have to steal to get their fix.

        Seems to me like the root cause is the illegality of the drugs. I hope you never have to deal with substance abuse problems yourself. You won’t like being on the dehumanizing end of the stick that you’re presently poking with.

          If you're going to give junkies their fix, are you going to buy my alcohol too? What about my gambling debts? What about my escort bill for my sex addiction? Shy are you differentiating addiction to drugs?

            Junkies and meth-heads are a different kind of animal from your average drunk, and the reality of the proposal that you responded to is a simple economic analysis of investing in keeping them placated or paying for the damage they cause. It's far cheaper to prevent rather than react and repair.

            If we ended the War on Drugs we would be doing exactly this thing and saving billions of dollars doing it.

              I don't have anything to add, other than my appreciation for this comment. Glad I'm not the only one here that gets it.
