Solar Power Systems.


Please select the correct size solar power system under the SOLAR POWER tab above.

In order to design and quote, we first require information from YOU.

There is no standard "one size fits all" system; without this data, we are UNABLE to give a quotation. If you are not sure of the answers, please speak to your local electrician or an electrical engineer:

  • Should the system be grid tie ? Check with your municipality if this is allowed. If it is not allowed to export power to the grid we will install a Grid Tie Limiter.
  • Or should the system be self-contained as a backup system with batteries?
  • Should the system be a backup system with grid-tie facility?
  • Single phase or three phase?
  • We need the total daily consumption in kW/hr.
  • We need the peak power consumption in kW.
  • Autonomy required? (the backup time required from batteries when there is no sunshine)
  • Within how many days must the battery bank recharge after a full discharge?
  • Where will the system be mounted : ground, flat roof, pitched roof, etc.?
  • Co-ordinates / location.


Ballpark figure on the cost of a solar power system.

You can work on about R22 - R28/W (grid tie system) to R35 - R40/W (with battery backup).
                        To get a rough price indication, take the total kW/hrs used in a 24-hour period, divide it by 6, then multiply by the Rand figure given above.
                        Calculation Example: Total kW/hrs in 24 hours = 45kW/hrs / 6 = 7.5kW (or 7500W/hrs) x R28.00 = R210 000.00 for a grid tie system installed, excluding batteries.

                                                

If this is within your budget and you want to go further, then please CONTACT US. We would have to do a detailed design which we would charge for.
