As load shedding continues to frequent like some sort of crazy thing, a lot of South Africans are left desperately looking for a quick long-lasting solution to mitigate load-shedding. One thing that everybody in Cape Town, Gauteng, KwaZulu Natal, and all the other provinces can tell you with confidence is that they want a reliable, efficient DIY solution to the power crisis. South Africans have now started looking into alternative energy sources.
Most South Africans have heard about, and are aware of solar power. This, however, doesn't mean everybody understands how solar works and the components that make up an effective, rather complete solar system.
The key component is a Solar Panel. The Solar Panel is made of solar cells that are typically made from silicon, which is a semiconductor and can generate electricity. This process is known as the “photovoltaic effect”
Quick flow overview of how solar works.
Solar panels work by absorbing sunlight with photovoltaic cells, generating direct current (DC) energy and then converting it to usable alternating current (AC) energy with the help of inverter technology. AC energy then flows through the home’s electrical panel and is distributed accordingly. Here are the main steps for how solar panels work for your home:
- Photovoltaic cells absorb the sun’s energy and convert it to DC electricity
- The solar inverter converts DC electricity from your solar modules to AC electricity, which is used by most home appliances
- Electricity flows through your home, powering electronic devices
- Excess electricity produced by solar panels is fed to the electric grid
