Assume you have a 400W panel, but due to inefficiencies the actual output is 25% lower than 400W, which equals 300W effective. With 4 hours of effective sunlight, one panel produces: 300W × 4 hours = 1,200 Wh or 1.2 kWh per day. If your house uses 30 kWh per day, then you need: 30 kWh ÷ 1.2 kWh per panel ≈ 25 panels.
A typical 300-watt solar panel is 65.8 inches long and 36.1 inches wide. It takes up 16.5 sq ft of area.
To calculate the required solar panel output, multiply the desired output by a buffer (usually 1.2 to 1.5). For example, with a 20% buffer, a 20 watt solar panel would provide 7.2 kW of power.
The size of solar panels varies, with no definite answer. Their wattages also differ as each system operates on different power levels. To learn more about solar panel sizes and wattage, keep reading.
