   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 live in a European country, where the phone company hasn't bothered to come remove the old unused copper phone lines in the last 5 years. Thousands of dollars worth of cables running past my house alone, and no one has bothered to go strip it in the night and sell it

         This feels like one of those USA problems that would be better addressed by funding decent social services (free healthcare, cheap housing, addiction treatment programs, etc).

            America is an entirely different cultural universe and simple things like this seem logical but just wouldn’t really solve the entire problem, IMO, as an American that’s lived in Europe for a decade+.

            Another great example are the “open air” transit systems in Germany, Poland, etc. where you can freely enter trams and buses, with inspectors patrolling infrequently to check if you bought a ticket. That kind of system would absolutely never work in America, no one would pay, and the ticket inspectors would be hated as some kind of secret police.

               The Netherlands is phasing out open air transit because it doesn’t work. Aggression towards public transit service workers is at an all time high. Most stations have moved from no barriers to barriers over 2 meters tall. Refugees have their own bus lines.

               Society is going backwards in rapid pace I’m afraid.

                  That is factually incorrect. The Netherlands is not phasing out open air transit (barriers are only a thing at the high-volume stations) and the barriers are rarely 2 meters tall (at most stations they are waist-high).

                  The "refugee bus line" is a single ferrying route between a rather awkwardly-placed arrival center and its nearest train station. The main issues were caused by refugees being unable or unwilling to pay the bus fare, and considering all of those refugees are living off an allowance anyways, having the arrival center itself pay for the buses and making them "free" really is a no-brainer solution.

                     The Netherlands used to have open air-transit. But in the last years, barriers have been installed at nearly every train station. There are 1700 barriers according to Thales. 90% of travelers encounter at least one barrier during their trip. A lot of them are two meters tall. Some are only waist high.

                     Segregating refugees onto their own bus because they are aggressive is what South Africa did during apartheid. Even the United States isn't doing that anymore. It is a disgrace. Just give the refugees a card that you load with €50 every month. You can automate that and they can pay for the bus with that card.

                     And no, it is not a single route. I guess you are referring to the Ter Apel to Emmen line. That is indeed one of the segregated bus lines. There is also the line from the DISA building to the night shelter. There are taxi services for underage refugees. There is arranged bus transport between locations.
