Many solar systems require little or no maintenance to operate smoothly throughout the year, but you should have them service occasionally. Dirt, leaves and dust can accumulate and reduce the amount of power that your system can produce. Have a licensed installer come out regularly to preform maintenance on your system.
When switching over to solar panel, take the time to evaluate all of your energy needs. Solar panels are far from cheap, and there might be more cost effective ways that you can reduce energy consumption in your home. By reducing consumption, you can reduce how many panels you need, thereby reducing your overall purchase and install costs for a solar system.
