A home solar panel system consists of several crucial components, namely:
Solar panels typically comprise monocrystalline (single cells of silicon) or polycrystalline (silicon cells with multiple structures). Both harness sunlight with superb efficiency, are durable and can be produced at a relatively low cost. This makes them an excellent choice for residential properties. The panels are manufactured by wiring the solar cells together and encasing them in glass. As they capture direct sunlight, they convert the energy into electricity through the photovoltaic effect.
Inverters are electronic devices that convert the direct current (DC) supplied by the solar panels into alternating current (AC) using semiconductors. This current can then be used to power household appliances as standard.
- Mounting structure (racking)
A strong structure is mounted onto your roof to hold the panels securely. Choosing the optimum angle to maximise exposure to the sun is critical. It should only be attempted by experienced amateurs or, preferably, a reputable solar electric system installer and service provider.
- Batteries (not a requirement for functionality)
Solar batteries are optional and can be very handy for days when cloud cover prevents sunlight from hitting the panels. They store any excess energy and can release it as required, especially at night. This gives residents more autonomy over their energy use and less reliance on the national grid.
