WHICH SOLAR POWERED PUMP IS SUITABLE FOR YOU?
Solar powered pumps should be selected on the basis of suitability depending
upon various factors such as:
- Farm Size to be irrigated.
- Water discharge requirement.
- Availability of shade free areas for solar panels.
- Concerning a thumb rule, there is no certain method to decide on pump size;
however, daily water requirements and the ground water level can give indications.
HOW MUCH LAND DO YOU NEED?
As a general thumb rule, approximately 10 sq.m of land is required for every 1,000 Wp
of solar panels installed.
Although it is often mentioned that a 2 HP pump can cater to about two acres of land,
and a 7.5 HP is said to cater to 10 acres of land, this data is not universally applicable
since the output of pumps changes depending on the groundwater level, and the type
of irrigation required for a particular crop, e.g., flood irrigation for paddy cultivation
