See how to test your solar panel for open voltage and current reading. Results will vary depending on sun strength, time of day, angle of light and temperature.
One of the major benefits of solar energy is that it is renewable. The sun (generally) shines each and every day, and there is no reason to worry that drawing power from the sun will somehow render it unusable in the future. Using solar energy, therefore, is a safe and reliable way to power the Earth.
Once you have solar energy panels installed on your home, make sure that you keep them clean. Many people do not realize a cleaner panel will attract more of the sun's energy. Depending on the area you live in, you should wash your panels every two to four weeks or so.
