Obviously there is a definite benefit for the environment, but what are the financial costs versus savings?
Well I’ve heard that you can still be hooked to a grid and during the daytime when most people are not home and not using a lot of electricity it reverses the meter. I also heard there are energy credits you can earn, you can eliminate your electricity bill and earn these credits which can be sold. The solar panels I’m talking about are the ones that would power everything in the house.

You can add free solar power to a home just by opening the drapes on a sunny day and closing them at night. So there is no simple answer. It may depend on what you want the solar energy to do. Heat water? Preheat water for a gas or electric water heater? Supplement a wood-burning stove? Do you expect it to help in summer or winter or both? Some rooftop units collect solar heat energy and others are photovoltaic. Newer and cheaper photovoltaic technology is on the way. But the sun must be shining unless you can store the energy, and that may cost a bit too.
