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.
