The application of solar energy is more and more widespread, effective energy saving, and power supply in places where electricity cannot reach, bringing great convenience to irrigation

How to choose solar pump system? We can consider from the following perspectives:

1.System selection (necessary information)

Item

Information

Effective sunny time

Installation address/solar website

Water head

From the water level, vertical distance

Water request in one day

According to historical data or calculation

 

Working days in one year

To see how much money we can save  per year

Pump power

According to water head and cubic

Inverter power

According to pump

Solar panel power

According to inverter and sunny time

2.Solar modules selection
