Why dont Floridians install panels themselves? Airco use correlates strongly with sunshine, so I imagine they pay themselves back within a year or three.

- zdragnar 3y agoHurricanes, probably.
- ozim 3y agoPV is a bit counterintuitive in that it loses efficiency when it gets hot. Best efficiency is when circuitry is a bit colder and not in full sunshine and 30+ degrees C. Full sunshine around 15-20C works well. So coupling AC with PV seems like a no brainer it doesn’t work that well when you really want to blast that AC full power because panels get too hot from the outside temperature.
- fullspectrumdev 3y agoIs it possible to use some form of cooling on the panels? The heat would need to fuck off to somewhere though…
- someplaceguy 3y ago> PV is a bit counterintuitive in that it loses efficiency when it gets hot. Is that significant enough to matter? How much does it lose?
- patall 3y agoThere was a comment here on hn from a guy that measured the heat effect. For them the loss in efficiency was 12%. Which would be somewhat negligible. Edit: here it is https://news.ycombinator.com/item?id=38688116 https://news.ycombinator.com/item?id=38688116
- brnt 3y agoEfficiency isn't the uptimate goal, that is: do you get enough power per currency spent? Efficiency may drop, power output won't. It might plateau, but that's OK.
- epistasis 3y agoGood question! First, will the utility let you do it, second will they charge you excessively for the privilege, third, will your local municipality allow it, fourth is there a base of skilled labor to make it happen? Germany got around all these obstacles, but if the state and utilities are in the way, it's hard for individuals to make the move to solar.
