    You might not entirely cover the power consumption of an AC, but you can drastically lower the cost of using one by at least partially generating your own electricity. As for the technical aspects I cannot argue at all, as I have no knowledge whatsoever in that regard.

      It will take years before you make that money back on the investment though, depending on local taxation and electricity prices. And that’s assuming that you have a decent enough orientation in the first place - some people live on the north side of their apartment block!
      Always do the maths on PV for your situation, a 25 year positive ROI does not justify a purchase but a 10 year ROI might.

      We need more A/C to survive climate change, but the solution can’t be “put PV on balconies” because it’s highly situational (not everyone has an adequately big south-facing balcony) and won’t solve your problems if you could not afford the cooling bills in the first place (the only people who consider a 10 year ROI a good investment are the ones with capital to spare on home improvements). As with all personal renewable tech, it’s a cost-saving tool for the well-off, not a structural solution to anything.
