General Information |
: |
A solar PV water pumping system consists of a number of solar PV modules connected in series - parallel combination to generate sufficient power to operate a motor pump. The solar PV modules are mounted on a metal frame in a manner that the mounting frame can be turned / tilted to ensure that the modules keep facing the sun throughout the day. The system does not have any storage battery since power generated is used directly then and there. The SPV array converts the solar energy into electricity which is used for running the motor pump set. The pumping system can draw water from the open well / bore well or stream / pond or canal. The normal discharge rates of water for different types of pumps are given above. |
