Before purchasing solar panels, check the track record of the company that is selling them. Many panels come with lengthy warranty periods of up to twenty five years, but this warranty is only good if the company is still in business. Make sure to ask how long the company has been in operation and check ratings with organizations like the BBB before making your purchase.
Talk to the company that you plan on having install your solar system and see if a sun tracker is a good fit for your system. Sun trackers use very little energy and will maximize the amount of power your system can produce. If you have the space and resources, a sun tracking system can help you maximize your energy production.
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.
Find out what kind of warranty comes with any system you are considering. A solar energy system should last you for at least twenty years, so be sure the company you are dealing with can support it. If there is no warranty, or an extremely limited one, it may be time to keep looking, no matter how great the savings are.
