Solar Pump

Ercon Energy is offering most competitive Solar Pumping solutions with collaboration of  Solar World.

Solar water pumps (SWP) use electricity generated by photovoltaic (PV) panels to pump water from bore holes, wells or reservoirs directly onto fields or into a storage tank for gravity based irrigation.

 With no fuel inputs and simple operation, SWP are cheaper, cleaner and more reliable than diesel pumps. Once installed, SWP are low maintenance and have a long life if maintained properly. Water supplied can be used to irrigate crops, water livestock or, in some cases, provide drinking water.

Technical Characteristics:

Efficiency Improvementscan be made by using automatic electric sun tracking arrays.

Water Tanksare optional, but enable storage of water for gravity pumping on demand.

ComponentsPump, controller, solar panels, wiring, piping, water tank

System sizedepends heavily on site and pumping requirements

Fuel typeneeded High levels of sunlight

Fuel replacedDiesel, Petrol, Gas

Solar array size 8 – 10 m2 /kW for silicon PV panels

System power 0.4 kW – 20 kW

Typical liftrange 5 – 200 m

Typical flow rates10 – 400 m3 /day

Lifetime Pump5 – 10 years, Panel: 25 years

Pumps operate without supervision and require very little maintenance compared to diesel set-ups, however, routine maintenance is necessary to ensure a long lifecycle. This could include checking for faults, the cleaning of panels and pump filters, and the maintenance of the site around the SWP.

The breakeven time of a solar pump against the cost of diesel pumping is typically between 1.5 – 4 years. For instance a pump operating with 50 m lift and flow rates of 20 m3 /day will breakeven after 20 months when compared to a diesel pump running for 5 hours a day with diesel costs of Rs. 80 per litre. As diesel costs continue to increase, and solar pump systems become more affordable, this breakeven point will be reached sooner and savings will be higher.
