I said it was not economically feasible. Possible, yes. There is enough square feet of roof to support the house, even in the winter in the US. As for the snow, hire someone to brush it off each morning.
You must be joking. I want to put an small ham antenna on my roof. It's going to take a hydraulic cherry picker to safely get up there. That's only feasible in the summer time. The cul de sac in front of my house is too tight for the snow plow. We routinely have 18 inches of snow on the street from Thanksgiving until Ground Hog day. The snow on either side of my driveway is usuall piled 3 to 8 feet deep. Nobody is getting near my roof to brush it off each morning.
You are way wrong
Punch the numbers in yourself on how much solar energy reaches the earth at any given location, at http://fuzzo.com/science/RadData.htm
For my house at about 44° latitude, the amount of solar energy reaching the surface at noon is
404 watts per meter² June 21
253 watts per meter² Sep 21
97 watts per meter² Dec 21
My house which is about average size has 140 meters² of roof space (1500 feet²) and the best solar panels have only 15% efficiency
So we are talking about maximum
8.5KW June 21
5.3KW Sep 21
2.0KW Dec 21
Now throw in the fact that my (and no one else’s) entire roof faces the direction of the sun all at once, the solar cells will have to be spaced, and there’s night time, 1 out of 3 days are cloudy and/or rainy where my house is, the pollen, dust, bird §¶‡+ and other debris that will accumulate on the solar cells, there are many trees within a few hundred feet and the snow that falls on the roof and watch those numbers plummet right down
Your typical house need 30KW hours per day to run,
Sorry but solar is and will always be a pipe dream. I'm actually shocked that on a Conservative site I'm reading some of the blather and Liberal wishfull thinkings posted in this thread
The whole industry is propped up by Liberal feel good but actually do nothing policies, Take away the subsidies the industry will die immediately.
