Less than USD 25 per megawatt-hour of solar power — these kinds of prices are not uncommon any more in sunny regions. Thanks to its continuously falling costs, photovoltaics is on the right track to becoming the world’s most cost-effective source of energy. It thus totally makes environmental an...

If the City of Cape Town truely wants to embrace the use of Solar Power and increase the update of Solar PV in the residential space the following measures need to take place. 1. remove the Service charge for SSEG for a period of three years 2. Introduce net metering for a period of 3 years - this will eliminates the need for the costly AMI meter - - those with prepaid meters will have to go back to previous electromechanical induction meters. Users will not feel being ripped off by the city making a large profit on their solar power 3. Provide Professional Engineering services at a fixed cost for those installations that need approval ( SSEG ) 4. Setup a specialist team within the City's Electricity dept that can speedily assist users in getting systems approved to the required standards.

Here is a graph showing 2 actual solar PV energy yields in Noordhoek. The units are in kWh/kWp . kWp is the peak nominal power output of a PV module at solar radiance level of 1000 w/m2. Typical home values of kWp are around 5 kWp equivalent to around 12 PV modules @ 400 w each. So if for example your PV array was rated at 4.8 kWp then you can expect an electrical yield of around 900 kWh in January and 300 kWh in July
