I’m not sure how solar works in parts of the world with freezing weather plus gloomy skies.
I guess you need to see the sun for the solar panels to collect the heat, as they rely on the radiative heating effects of the sun to warm the black surfaces.
Most of the heating devices that I have seen which use solar, utilize black copper tubing to heat the water or air inside. I think that is how the heating part works when it comes to solar heating devices. I would adore to have one now because our central component just costs way too much to run on a regular basis during these freezing Winter time days. There is no sun though so I don’t even guess solar would be an option this week, unless the solar can somehow store the heat that was collected previously. But I really don’t suppose how it works as I am not an Heating plus Air Conditioning professional or anything adore that, however so yes, this month is a freezing one plus I am going to work for a couple of tenths plus then ride our bike to go visit our friend who lives in a little campervan. She doesn’t have any gas heating in the van right now because she had to order a nut for the gas line. I have it because she had to get it mailed to our flat because she has no address, living in the van plus all. She must be freezing though because of no Heating plus Air Conditioning method plus the temps this day getting close to the cold zone.
