Keep your solar panels clean. If your solar panels are dirty or obstructed in any way, they won't work as well. Keep an eye on your solar panels and clean them if they're not quite looking their best. Hosing them down occasionally will ensure that they are much more efficient.

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.
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.
