How does photovoltaics work?

Photovoltaics refers to the conversion of sunlight into electrical energy using solar cells. Instead of obtaining your electricity from a source several kilometres away, you can produce the energy at home.


Design of a photovoltaic system:

Before the sun can be turned into electricity, the sunlight must first hit the solar module.

  • The solar module, the electricity generator, is the blue element on the roof, which is mounted securely using a mounting system. Each photovoltaic module consists of several interconnected solar cells. Solar cells function by converting sunlight into direct current. However, this electricity cannot be used directly and is therefore routed to the inverter.
  • Inverter:The photovoltaic cells deliver direct current, which has to be transformed into useable 50Hz alternating current by a static converter. The inverter is used to convert the solar direct current from the solar modules into alternating current for your home with the minimum possible loss.
  • Battery: The generated energy is stored in a battery and used at night or whenever power is required. The battery bank contains one or more deep-cycle batteries connected in a series and/or are parallel depending on the voltage and current capacity needed. The batteries store the power produced by the solar array and discharge it when you need it.
  • Meters can be used to accurately record the system yield.
