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.
