Question from Adam: I hope you can answer a question about solar power for me.

I have a small outbuilding that’s located about 120 yards from my house. This outbuilding has a dark green roof and it gets extremely hot inside on hot summer days.

What I’d like to do is install a fan in the eve of the building to pull fresh air into the building while expelling the hot air, but there’s no electric service there to power the fan. Can you help me with this? [Read more…]

Can I safely replace the old rechargeable batteries in these lights with something like Energizers? [Read more…]
