Dad has a big work shop in a very large shed, he has yard lights on all the time to . Would this benefit his business . I heard the solar panels only save a tiny bit on electric. He also rents out part of the yard and they constantly leave lights on. Is there any sort of machine you can put money in that turns lights on and when ur money runs out they turn off?
Solar panels wind turbines
