Clean Solar

I have read several studies that indicate if you do not clean your solar array off you can loose anywhere from 10-30% production after a year. If you clean them every three months you should maintain maximum efficiency.

    In Southern CA we recommend a powerful water spray about twice a year. The rain cleans them off in February, so that makes 3 times a year.
