In Reply to: Solar Panel Question posted by WNYBill on March 19, 2021 at 06:02:14:
Hey there Bill, good questions, here's my opinion based on my experience having used several different makes n models of solar panels over many years:
My question, while they are melting the snow off the uncleared half panel, do they make any electricity?
1) YES depending on the snow and its depth, a solar panel could still produce some degree albeit less, of electricity if partially or fully snow covered. Obviously a dusting is different from a 6 inch covering as if 10% versus 50% is covered. As an example, mine (RV roof mounted) still produce electricity if I'm parked under a full shade cover although not near as much as if I'm parked in bright sunlight. Similar if extremely dirt and dust covered they don't produce as much as if bright n clean, and like almost none at night DUH.
2) Similar, a partial shaded panel obviously cant produce the electricity of one in the clear
3) As far as any heat to melt snow, if a panel is only rated at say 100 Watts to begin with and considering the large surface area coupled with the fact its colddddddddddd outside, much of any heat generated will be transferred to the surroundings IE I don't anticipate very much snow melt caused by the panels operation alone....
NOTE This is my opinion (others may have different opinions) based on personal experience, I have no specs or hard scientific or test data to back it up. If one has the time to dig and research Im sure they could provide more detailed technical information, maybe some fine gentleman here could provide such for you......

Today's Featured Article - Earthmaster Project Progress Just a little update on my Earthmaster......it's back from the dead! I pulled the head, and soaked the stuck valves with mystery oil overnight, re-installed the head, and bingo, the compression returned. But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
