Solar fences are gaining ground in Europe, as households continue to invest in renewables amid the war on Iran.

    Shading degrades solar module performance, but I was thinking about thrown stones and sctatching with a hard metal bit which immediately destroys the prestressed glass pane only designed to withstand 30 mm hail.

    And I live in a very nice neighborhood. Elsewhere, these things would be destroyed weekly.

      Most of these fence panels are bi-facial, i.e they have panels on both sides. They catch light reflected from the ground/snow/etc. They cost a bit more than single pane panels, but not a lot more. Like 15-20%.

      You dont get nearly double the power, but they tend to work a bit better then single panels facing the sun because solar panel efficeny degrades with heat. When the sun is at its strongest, traditional roof mount panels take a significant efficiency hit. Because bifacial panels are generally positioned more flexibly, they have much better cooling that compensates for their bad angle.

      Have no idea what you mean about vandalism. I see solar panels all around in various neighborhoods in a big city and they are never damaged. You will likely never have an issue, and even then the individual panels aren’t that expensive to replace. A wood fence would likely cost more to cover the same surface area of one 7ft x4 ft panel.

      I don’t know what kind of failed state you live in (Haiti?), but I am near 100% certain that they would be fine in any residential neighbourbood that I previously lived in and that includes places in 3rd world countries. There would be probably a higher risk of them being stolen than intentionally damaged.
