Peak Sun Hours: Short introduction
1 peak sun hour = When the intensity of the sunlight averages about 1000 per meter square (1kWh/meter2).
Why consider peak sun hours? The solar panels are designed to produce their rated wattage output under standard test conditions – STC. Which includes, 1kWh/m2 of sunlight intensity, Temperature: 25°C (77°F), and Air mass (AM): 1.5.
This is why we use the number of peak sun hours as a reference when designing the ideal solar system size.
