Residential photovoltaic panels
South Africa is relatively new to the renewable energy market. We have been experiencing consistent problems with energy supply from Eskom from 2008. Again in March of 2014 mass rolling blackouts were put into effect. Eskom again claiming that wet coal was to blame for this "load shedding". We believe that Solar PV solutions offer one key energy substitute to Eskom power based on South Africa's solar irradiation profile.
I have seen these solar panels on roofs lately but what is PV?
Photovoltaic energy is the direct conversion of light into electricity at the atomic level. Some materials absorb photons of light and release electrons exhibiting a property known as the "photoelectric effect". When these free electrons are captured , an electric current results that can be used as electricity. WOW does this remind you of first year engineering or what! Instead below see a basic diagram of how sun energy is used to power your household appliances.
Are there different grades of solar PV panels?
Absolutely! As with all things in life you pay for what you get. At Afri-Market we only work with reputable suppliers who will always back the warranties of their products.(see warranty section for suppliers cover) Im sure lately you have noticed cheap imports popping up everywhere promising lower and lower prices. What you may not know is that there are different grades of PV, notably A,B and C grades. C grade is the absolute cheapest product available and this is generally found at the local hardware store. The efficiency of these panels drops off dramatically after a year or two. Afri-Market modules are manufactured by one of the largest PV companies in the world and are guaranteed for 25 years at 60-80% efficiency over its lifetime. So rest assured we have your long term solution in mind when we offer any of our products.
Why PV, why now?
Over the last 3-5 years PV modules have drastically reduced in price, and experts agree that within the next 2-3 years we should be seeing parity in price between Eskom power and installed renewable energy. The limitation with residential power consumption is that most people use the energy at night when everyone is at home. This necessitates the use of batteries which regrettably adds to the price of the system. However Afri-Market has a completely different approach and believes that a more modular approach is required. Starting very small and growing the system as and when required, or as finances allow.
