The number of solar panels a home needs is directly tied to monthly electricity consumption. Most South African households using between 600 and 800 kWh per month will require:

• 8 to 14 solar panels based on individual panel wattage
• A 5kW to 8kW inverter
• Sufficient battery capacity to cover overnight and load shedding demand

One advantage of being in Cape Town or the Western Cape is the region’s exceptional sunshine, averaging 5 to 6.5 peak sun hours daily, which allows panels to generate more energy per unit than in lower-sunshine areas, sometimes reducing the total number of panels required.
