Solar panels capture energy from the sun, so their output, or wattage, is an important detail to think about determining your energy needs. But how much energy can they produce?
When looking at solar panels, you might notice numbers like 245W, 300W, or 345W. This number tells you how many watts the panel should generate in full direct sunlight. The energy a solar panel can capture is measured in watts (W). Most solar panels for homes have power ratings between 250W and 400W. Solar panels are tested to see how much direct current (DC) power they make under specific conditions. These tests use UV light and controlled temperatures to mimic real-life outdoor settings.
An Example of Solar Panel Output
Let’s say you’re using solar panels with a 290W rating. You decide to install 30 of them on your roof. Together, these panels make an 8.7kW solar system (290W × 30 panels = 8,700W or 8.7kW).
If your panels get 5 hours of sunlight each day, they’ll produce about 43.5 kWh of electricity daily (8.7 kW × 5 hours). Over a year, this adds up to roughly 15,800 kWh (43.5 kWh × 365 days). This is enough to power most homes.
