An off grid solar pump (where you replace your dedicated Eskom connection with solar power) has a very good return on investment. No need to replace your existing pump and motor, just the electricity supply. Indicative payback figures are as follows:
|kW System||Cost||5 Yr Saving||10 Yr Saving|
The “Solar Cost” includes the solar charge controller, solar panels and cost of wiring, lighting protection etc. This is all you need apart from the structures to mount the solar panels. Note that we oversize the solar panels by a factor of 1.8. In other words, the solar panels costed above for the 2.2kW pump is actually 4kW of panels.
Note: No batteries involved. The panels have a 30+ year lifespan.
Solar power is a perfect fit for water pumping with storage. It can be used for direct irrigation as well, but remember you are dependent on the weather!
The following assumptions were used in the calculations:
