Solar pumping system The YCB2000PV solar pumping system serves to provide water in remote applicarions where electrical grid power is either unreliable or unavailable. The system pumps water using a high-voltage DC power source such as aphotovoltaic array of solar panels. Since the sun is only available during certain hours of a day and only in good weather conditions, the water is generally pumped into a storage pool or tank for furher usage. And water sources are t...
