Diesel is the largest line in the cost of irrigation. Sunlight is free, and the pump cannot tell the difference.
Solar-Powered Water Pumping
Converting irrigation pumps from diesel to solar, sized against real irrigation demand rather than the pump's nameplate rating.
The problem
A 20 hp diesel pump burns three to four litres an hour. Over 1,200 running hours in a season that is fuel alone, before maintenance - paid in cash at a point in the year when the crop has not been sold yet.
How we solve it
Sizing starts from irrigation demand, not from the pump: how many cubic metres a day at peak season, against what head. That sets the array, and it is usually smaller than a supplier selling by the kilowatt will propose.
We use an MPPT pump inverter rather than batteries. Batteries add a third to the cost to serve a need that does not exist here - irrigation happens in daylight.
What it delivers
Running cost close to zero after installation, and a payback period calculated from the farm's own recorded diesel consumption rather than from a national average.
What it includes
-
Demand-led sizing
Array capacity comes from m³/day and head, not from the pump's horsepower.
-
MPPT inverter
Maximum power point tracking without batteries, because irrigation is a daylight activity.
-
Generation metering
An energy meter records what the array actually produced against what it was promised to.
What you receive
-
Feasibility study on the farm's own figures
Recorded diesel use, the array size required, and the payback period.
-
Supply and installation
Array, inverter and mounting, wired and commissioned.
