How effective are they and how much? (4 bed detached)
Answers:    I hold solar electric panels within my back patio and I think they do great. They are setup next to batteries as a battery-operated backup system. On sunny days I normally turn sour the utility power and just run the house from solar. It is severely nice when the power goes bad from the local utility to still have power.

The nation all around me have noticed that when they hold no lights that we do but none of them has any plans to install. It is the upfront cost that stops most ethnic group.
its economical but costly to install
