Posted by: Yes Solar Cape (Cape Town, South Africa) – 28 August 2010
Solar water heating is gaining popularity all over the world due to the many benefits it offers and because it is relatively inexpensive and easy to install. With the South African climate our high levels of irradiation make the installation of solar water heaters a sensible choice.
The following are 5 good reasons to go Solar:
Power Shortage – South Africa cannot currently meet the energy demand in the country with existing power generation capacity.
Rising Energy Costs – Electricity costs are still low in SA, but Eskom forces a 25 % price increase per annum over four years.
Independence from providers – Solar energy ensures continued power supply on key appliances at home or in the office, thereby mitigating damage during power surges and outages. It reduces the household reliance on Main Grid Energy supply, and it ensures hot water during load shedding.
Free Energy – Solar Energy is free, which translates into monthly costs savings on electricity bill. South Africa is one of the regions with the highest solar irradiation in the world. Solar Energy allows you to meet 90% or more of your hot water requirements at no charge once you have recovered the installation costs.
Environmental Footprint – In South Africa, the most abundant source of energy is coal, which is responsible for CO2 pollution. A 150 litre solar water heater can replace on average 4.5 kWh of electricity per day, resulting in environmental annual savings of 3.0 tonnes of CO2 and 12.2 kg of NOx.
