PV 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.
