I much prefer hot af to an icy hellhole. Heating takes up a huge amount of energy and you can’t really do it in an environmentally friendly way unless you get creative. The good thing about the heat is when it’s the hottest, solar panels generate the most energy. It’s a cooling solution that scales itself with the temperature.

> The good thing about the heat is when it’s the hottest, solar panels generate the most energy. Incorrect. Peak PV efficiency occurs at relatively low temperatures. Perhaps you mean "when it is hot, there tends to be lots of sunshine, and so there's lot of PV generation" ? That's true of some places (Southern CA, AZ, NV, NM) but less true of others (Louisiana, Alabama, Mississippi, Georgia etc).

Photovoltaic modules are tested at a temperature of 25° C - about 77° F, and depending on their installed location, heat can reduce output efficiency by 10-25%. As the solar panel's temperature increases, its output current increases exponentially while the voltage output decreases linearly. In fact, voltage reduction is so predictable that it can be used to measure temperature accurately.

However, solar panels can get as hot as 65 °C (149 °F), at which point solar cell efficiency will be hindered.

  Either ways, if it’s hot there is going to be a lot of uninterrupted sunlight.

    It can be hot, cloudy, and humid all at the same time. Sincerely, Ohio

    The coldest days around here are the ones where the sky is completely clear.

      That doesn't mean that hot days tend to be cloudy.
