When thinking about investing in a solar panel system, you should consider such factors as the typical weather conditions in your area. Solar panels are a good option if there are five hours of sunlight a day in your area. When there is little sun or snow on the roof, you may have to use other sources of energy.

Keep in mind that purchasing a solar power system often enables you to receive tax credits from the government. You may find that you get back as much as 30 percent of the total cost of your system. So, if you look into a system and think that it costs too much, investigate whether or not you will get credit back to determine how affordable it actually is.
If you want to have a solar system installed on your roof, make sure you check the credentials of anyone working on your home. Check certifications, verify references and generally research the company prior to signing any contract. This is a big investment, so make sure that you choose a reputable company.
