Real-World Performance Gap: Expect 240W panels to deliver only 83-96% of rated capacity (200-230W) under peak conditions, with seasonal variations ranging from 0. 6 kWh daily in summer, making accurate system sizing critical for meeting energy needs. . Now, the amount of electricity in terms of kWh any solar panel will produce depends on only these two factors: Solar Panel Size (Wattage). A 400-watt panel can generate roughly 1. Losses come from inverter efficiency, wiring, temperature, and dirt.
