Stay informed about the latest developments in skid-mounted PV systems, prefabricated photovoltaic containers, containerized energy solutions, and renewable energy innovations across Africa.
Solar panels should be sold with motion sensors, floodlights and fasteners to prevent theft, and these security features should be subsidised by the government. Only 5% of South Africa’s energy comes from solar power while 85% is generated from coal. Loans, more subsidies and security for rooftop solar panels need to be put in place.
South Africa is making efforts to increase the use of solar photovoltaic energy. But it’s happening at a very slow pace. Solar photovoltaic contributes less than 5% to the country’s energy mix, despite the sunny climate, which is very favourable for solar photovoltaic energy generation.
As of 1 January 2016 the South African government gave a tax incentive through the South African Revenue Service for the installation of photovoltaic solar energy generation systems.
Photovoltaic solar systems greater than 1 MW p are depreciated with the schedule 50%, 30%, and 20% in the first 3 years respectively. Despite this aggressive tax incentive, South African companies are slow to adopt grid-connected photovoltaic solar systems due to the lack of public dialogue from the government concerning photovoltaic solar energy.
Recent installations of large First Solar CdTe PV systems were claimed to be competitive with other forms of solar energy: First Solar's 290- megawatt (MW) Agua Caliente project in Arizona is one of the largest photovoltaic power station ever built.
How Do They Compare to Other Panels? The Cadmium Telluride (CdTe) solar technology was first introduced in 1972 when Bonnet and Rabenhorst designed the CdS/CdTe heterojunction that allowed the manufacturing of CdTe solar cells. At first, CdTe panels achieved a 6% efficiency, but the efficiency has tripled to this day.
CdTe PV modules provide a beneficial and safe use for cadmium that would otherwise be stored for future use or disposed of in landfills as hazardous waste. Mining byproducts can be converted into a stable CdTe compound and safely encapsulated inside CdTe PV solar modules for years.
Nowadays, CdTe technology is the most popular thin-film solar panel technology and it is the preferred option by the top manufacturers of thin-film solar panels in the world. In this article, we will do a deep dive on CdTe solar panels and everything related to this technology.
