Hi,
I'm starting from scratch and I see a number of solar powered LED light devices, which is nice but I could end up with a bunch of tiny solar panels all over the roof Is there are solar battery system that I can hook normal lights up to?
Don't waste your time with those toy solar lights.
In this hobby, the power bill will be the least of your concerns
The cost of a proper solar panel, charging, battery setup wouldn't be worth the expense.
