Solar power has been working beautifully for our little rovers on Mars with an average temperature of about -80. Not to mention Hubble space telescope in orbit and little Voyager and Voyager 2 now outside of our solar system still communicating thanks to solar (still!) Power. My God, these people

Solar Energy Doesn't Work In The Cold [View all] ItsjustMe Feb 2021 OP

I really like the Swedish and Norwegian designs. Blue_true Feb 2021 #1

I thought the angle of the solar panel has something to do with the angle of the sun Hamlette Feb 2021 #17

Some people get trackers so your panels can follow the sun womanofthehills Feb 2021 #40

If you notice carefully, the design has solar panels on both sides of a "V" Blue_true Feb 2021 #56

Actually the cells are more efficient at colder temperatures. Throck Feb 2021 #2

They work better in the cold, so long as they aren't covered by snow or ice. Klaralven Feb 2021 #5

I am in the market for a solar panel snow rake. OAITW r.2.0 Feb 2021 #7

I think the general advice is to let it melt or blow off Klaralven Feb 2021 #8

Right now, I have 3-4" of frozen snow on the panels. Temps are below freezing, so very low output. OAITW r.2.0 Feb 2021 #10

You'd.be surprised how much light penetrates 4" of snow. Throck Feb 2021 #29

google it. my clients have used the squeegie type. garybeck Feb 2021 #25

Excellent! Nt garybeck Feb 2021 #59

They work in freakin space and on Mars! Dustlawyer Feb 2021 #47

Right- you actually get more power when it's colder nt coti Feb 2021 #13

Yes exactly... diverdownjt Feb 2021 #41

Also Mars.... RockRaven Feb 2021 #3

Imagine that. flying rabbit Feb 2021 #4

Cool. Carter tried to get us to renewable energy tech in the mid-70's, but way too much $ OAITW r.2.0 Feb 2021 #9

Jimmy Carter put solar panels on the roof of the White House, only to have them removed by Reagan AdamGG Feb 2021 #22

Antifa made snow, right? rickyhall Feb 2021 #21

Only when snow is bad! Grokenstein Feb 2021 #33

solar panels produce more power in colder temperatures garybeck Feb 2021 #24

Well, it doesn't work well when covered with snow. NNadir Feb 2021 #27

It's working out really well for me and my neighbors in NM womanofthehills Feb 2021 #43
