The number of solar panels you need depends on how much electricity your household uses each month. A typical South African home using around 1,000 kWh per month will generally need between 8 and 12 panels in a standard residential setup.

The best way to get an accurate number is to have a professional assess your consumption, your roof layout, and the level of backup power you want. Factors like geyser usage, air conditioning, and appliance load all play a role.
