Abstract: The present invention is a system for, and a method of automatic washing of solar collection panels from dust, sediment, and the like, which tend to accumulate over time. The solar collector washing system comprises: (a) a solar collector having a solar collecting surface, the collector disposed in an angled position; (b) a water pipe mounted substantially above the solar collecting surface, the water pipe having a plurality of holes distributed along a length of the pipe for distribution of water onto the solar collecting surface, and (c) a control mechanism, operatively connected to said pipe, for releasing the water supply.
