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.
Before making a choice on how many solar panels you use make a list of all the electrical appliances you use and the wattage and hours utilized by each one. This will be helpful in determining how much solar power you will need. No matter if you decide to install the equipment yourself or have someone else do it, this information will help your choices.
