If you want to know how different solar batteries compare - visit this Australian Test center where they have been testing batteries for several years under harsh conditions. Go and read the latest quarterly report

The ARENA-funded Lithium Ion Battery Test Centre compares various lithium-ion battery chemistries and products available in the Australian market against claims made by manufacturers. Tested under Australian conditions, the results of the centre will provide consumers with independent information on...

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
