A 400-watt solar panel is capable of powering a variety of appliances and devices. With full irradiance, it can operate a 360-watt (constant) AC load, which includes a combination of items such as televisions, laptops, slow cookers, and ceiling fans. Additionally, a 400-watt solar panel can run a small refrigerator with a 120 Ah battery. On average, it will produce between 1.6 kWh and 2.6 kWh per day or between 250 and 340 watts of power per hour.
This takes into account 10% of the investor's losses.
