It makes a lot of sense. Solar panels are getting affordable now. I see so many houses built hot climates that always makes me wonder how much energy these houses can harvest if all of them had solar panels on them.

- feet 4y agoIs that a problem if a majority of the energy for heating is renewable?
- DamonHD 4y agoHow so? I have solar PV on my roof and it makes no direct difference to the heating required. Except that I have a little generated energy that provides some warming inside from the appliances that it powers.
- 0cf8612b2e1e 4y agoIf solar panels block the sun from heating the roof in Summer (making it easier to cool) then the reverse is true in Winter. Some amount of free energy is no longer hitting the roof and potentially changing the energy equation. Is it a meaningful difference, I am not sure. However, it is only fair to count the impact on both seasons. Heating costs are significantly higher than cooling (larger absolute temperate delta required to go from 30f to 70f than 90f to 70f)
- DamonHD 4y agoThere is no meaningful solar heat transmitted in through the roof in winter, at least in a climate and building like mine, which is fairly typical.
