We are constantly striving to improve our already well designed energy solutions. Our ability to offer after sales support on all products is a non-negotiable aspect of our business. With the owner’s qualification in Electronic Engineering and attention to detail you are in safe hands.
Off-grid Solar Pumps (Updated Pricing)
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
2.2 R37,000 R133,000 R339,000
5.5 R77,000.00 R167,000 R424,000
7.5 R103,000.00 R197,000 R500 000
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:
Monthly Eskom connection fee: R1500
Eskom price per kWh: R1.20
Eskom yearly price increase: 9%
Sun hours: An average of 5 hours per day pumping through the year and up to 9 hours in summer.
