Carefully consider the types of solar panels you plan on having installed. Long ago, if you didn't have enough roof space, you'd need very expensive high efficiency mono-crystalline panels. There are now more advanced polycrystalline panels and even thin film panels. If you've got enough roof space, you might wish to look at the size of the panels in relation to their output capacity to avoid having insufficient panels that you need more of later.
You can dip your toes in the solar energy waters by simply installing a solar powered whole house fan. A solar powered attic fan turns on automatically when it becomes too warm. You'll reduce the cost of cooling your home by having this solar-powered attic fan remove hot air from your home. Additionally, as it is solar powered, your power bill will go down, not up.

Always use non abrasive cleansers on your solar panels. An abrasive cleaner can scratch the surface of the panel and cause permanent damage and affect how well the solar panel works. There are commercial cleaning solutions to use or you can use a pool skimmer with a very soft cloth on it.
