For example, a 300-watt panel with 18% efficiency might produce slightly less than 300 watts under normal operating conditions. Use the panel’s specifications to refine your output estimate.

2.3. Accounting for System Losses

System losses include factors like temperature, shading, inverter inefficiency, and wiring losses. These losses can reduce the overall electricity output of a solar system.

Estimate system losses to be around 10% to 20%. Multiply the potential output by (1 – loss percentage) to account for these reductions. For example, if losses are 15%, multiply by 0.85.

2.4. Example Calculation

Consider a system with ten 300-watt panels in an area with 5 peak sun hours per day:

Total Wattage: 10 panels * 300 watts/panel = 3000 watts (3 kW)
Daily Output (without losses): 3 kW * 5 hours = 15 kWh
Accounting for 15% Losses: 15 kWh * 0.85 = 12.75 kWh

Therefore, the estimated daily electricity output is 12.75 kWh.
