A solar powered heating unit may or may not work on the moon
Solar powered things work when they reflect off the sun. For example, if you have solar power energy it reflects off the sun making energy and then you can use it.
Depens on how many hours of sun it gets, on how much you want to drive it, and for how long/fast you want it to go. A solar powered speed boat - no. A solar powered commercial ferry - no. A solar powered dinghy for some casual fishing - sure.
Absolutely, in fact, better than here on Earth because there is no atmosphere to block some of the light. Solar is how many satellites and the International Space Station are powered.
Yes, solar power reaches the moon.
no stupid head
Typically they are powered by electricity (like plugged into the wall). So no, however, that electricity may come from solar power.
By using power stored in the batteries
yes it could
They use power from an internal battery when solar energy is not available.
Solar powere lights usually require a good deal of sunlight to be powered so it may not work if you do not get much light in your yard.
