Solar-powered pumps run on electricity generated by photovoltaic panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity or diesel run water pumps.An average solar panel makes about 300 Watts, and the power inverter that converts solar panel direct current to motor AC current is not 100% efficien. So in rough estimate you need around 15 panels, which will make around 4500 Watts, which will convert well enough to run your 2 HP pump.
How does a solar water pump work? When sunlight falls on the solar panels it produces direct current (DC) which then feeds the motor to pump out the water. However, in the case where the motor requires an alternating current (AC), the DC produced by solar panels is converted to AC using an inverter.
It's good for the environment as it is using sunlight which is renewable source of energy. The fountain come with high quality and durable feature. It uses highly efficient solar panel and new brushless pump which is easy to assemble and clean.
