Interesting but …

  1. Solar panels works differently in each place and time (for example rainy season in some regions)
  2. I heard that they are useless in cases where the sun is too weak or too strong, so they may “work” for a 1/6 of day, sometimes more and sometimes even less
  3. Depending on panel they may be many other problems with dust, snow and water. Of course there are panels with extra protections, but obviously it would not make them cheaper

That’s said it’s still interesting … I wonder how much money and space it require … Also I heard that there are 79% transparent panels that can be mounted on windows … :thinking:
