  • I believe, this is because it’s not yet a business model (nor a legal requirement). The first questions is, who even owns the lot and who has to power to make changes? Then, who gets to use the power output? Do you use it on-site or feed to grid? Do the local utility work with you or against you? (Hint: You are competitors now and running a grid is not free.)

    That’s just speculation, why solar-covered parking lots are not yet build much. The idea totally makes sense. It will probably take a either a startup company that figures out how and sells the solutions to the owners or a local government pushing for more solar.

    To those saying, it’s cheaper to build on a roof. Maybe, then do the roof, first, if it’s feasible. Is it cheaper to build on undeveloped land or farm land? Maybe, if you live in the middle of nowhere or drive a significant distance to do your shopping. Still, plenty of opportunity to build over parking lots.



  • This was expected. When solar panels were expensive, you had to optimize for output. When you get the same rate for any kWh, you optimize for output. Now that PV is cheap as fuck, of course, there’s going to overproduction.

    Now the dynamic will change. Instead of facing south, it becomes attractive to orient east/west. This generates more output on mornings or evenings. As a next step, you add batteries to the mix. Yes, they said they were expensive, need rare materials, and yadda yadda; except with lower prices every month, solar batteries are thing now.

    Also “overproduction” is relative. Most of our heating and transport is fossil. There’s a long way to go.
