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.
Don't be scared off from solar energy because you see certain companies shutting their doors. Solar energy is a big part of the country's future. It's not only great for the environment; it also saves you a lot of cash. That's a win-win across the board, and you'll be happy for looking into it now.
The efficiency of a solar energy system varies a lot depending on its exposure to the sun. If you live in a sunny area, your system should produce enough energy to cover all your needs but solar energy might not be such a good investment if you live in an area where the sky is usually filled with clouds.

If you are planning on meeting with a consultant to install a solar panel system, you need to make sure you are prepared. Have a list of all electrical appliances along with their wattage and the number of hours you use them on hand. Any good consultant will need to know this information before a solar panel can be installed.
