If you're thinking about installing solar panels to generate your own electricity, make sure that the roof you'll be installing them on gets plenty of good sunlight. Good sunlight occurs between 9am and 3pm. You'll generate the most electricity if your roof receives full, exposed sunlight between those hours every day.

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.
