Most residential panels in 2025 are rated 250–550 watts, with 400-watt models becoming the new standard. A 400-watt panel can generate roughly 1.6–2.5 kWh of energy per day, depending

To illustrate how many kWh different solar panel sizes produce per day, we have calculated the kWh output for locations that get 4, 5, or 6 peak sun hours. Here are all the results, gathered in a neat chart:
