==Suitable conditions ==

With solar water systems the water is pumped during the peak sunshine hours of the day. It can be stored in a tank, and therefore it is not necessary to use batteries. The storage tank can be sized to provide some reserve during cloudy or rainy days. In sub-Saharan Africa the typical storage is about 3 to 5 days of water demand. In environments where rainy seasons occur, rainwater harvesting can offset the reduced output of the solar pump during this period.
