Never install solar panels in a place that can easily be affected by storm debris. Solar panels are extremely sensitive, and because of this, should never be placed near trees or other tall structures that could cause damage to your panels if a strong storm were to hit the area.
Do not fret if you live in an area where it is frequently overcast. Solar power does not necessarily require full sun all the time. The sun's radiation penetrates through the clouds and can energize the solar panels effectively. Before you give the idea, do your research and discuss your options with reputable solar energy companies.

For families with four people, a solar energy system should produce approximately 5,000 kilowatts. This allows you to wash and dry five loads of laundry a week, run the dishwasher five times a day and power multiple televisions and lights. When deciding on the system, choose one larger than what you think you need. You can always sell the extra power produced to the electric company.
