kWp Explained: What Does “Kilowatt-Peak” Mean for Solar?

kWp (kilowatt-peak) is the output a solar array is rated to produce under standard test conditions — bright light, optimal angle, 25°C. It’s a consistent way to compare system sizes, but real-world output is lower.

Real-world output

A 6 kWp system in a good location might generate around 20–30 kWh per day, depending on sun hours, orientation and shading. Multiply kWp by your local sun hours to estimate daily generation.
