A Full Guide Apollo Support | November 28, 2025 On average, a residential solar panel generates between 250 and 400 watt-hours under ideal conditions, translating to roughly 1 to 2 kWh per day for a standard panel. However, actual solar panel energy output depends on several factors, including panel wattage, sunlight hours, and system efficiency.
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). Let’s have a look at solar systems as well:
Solar energy generation calculators are crucial for homeowners, businesses, and energy consultants to estimate the potential electricity generation from installing solar panels.
Let’s say you have a 300W solar panel, you get 5 hours of peak sun per day, and your system runs at 80% efficiency. So, this panel produces 1.2 kilowatt-hours of energy daily. Several real-world factors influence how much energy your panel can generate: Geographic Location: Sunlight hours vary by region.
