Do not rush in selecting the first solar power system you come across. Before you make a commitment with a company, you need to make sure you cannot find any better deals elsewhere. Check out your town's federal, state, and local incentives first. You can find this information at the DSIRE database.
Cleaning your solar panels does not need to be labor intensive. You want to avoid abrasive soaps at all costs, as they can deteriorate and even destroy your panels. So long as there is not caked up dust or bird droppings, frequent rinses with just hose water should be more than enough.
Don't waste your time lining the solar panels beneath an array of florescent lights--though it may sound tempting. Solar cells are not designed to generate a voltage from fluorescent light sources and this is a waste of energy of time. Any spot in the yard would be a better location for the panels.

Pathway lighting is a quick and easy way to harness solar power. Solar lights take in the sun daily and use the energy each night. These lights are very easy to set up and will even make your home look better.
Decide whether you want to be on or off the power grid. Many people look forward to getting "off the grid" when they switch to solar power, however this may not be the best choice. Staying on your power grid means that when you have poor sunlight conditions you have the ability to purchase additional power when you need it. As a bonus, when you produce more power than you use, you can sell the excess back to the utilities.
