A 450W solar panel typically produces 1.8-2.7 kWh per day under average conditions. The actual output depends on geographic location, seasonal variations, panel orientation, tilt angle, and weather conditions. Southern regions with more sun hours will see higher production, while winter months yield less energy than summer months.
A 400-watt panel can generate roughly 1.6–2.5 kWh of energy per day, depending on local sunlight. To cover the average U.S. household’s 900 kWh/month consumption, you typically need 12–18 panels. Output depends on sun hours, roof direction, panel technology, shading, temperature and age.
Solar panels are usually around 2m², which means the typical 430-watt model will produce 372kWh across a year. A solar panel system will need space on either side, so finding out your roof''s area is only one part of working out how much solar electricity you can generate, but it''s a great first step.
A 300-watt solar panel will produce anywhere from 0.90 to 1.35 kWh per day (at 4-6 peak sun hours locations). A 400-watt solar panel will produce anywhere from 1.20 to 1.80 kWh per day (at 4-6 peak sun hours locations). The biggest 700-watt solar panel will produce anywhere from 2.10 to 3.15 kWh per day (at 4-6 peak sun hours locations).
