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.
I have explained this topic in detail. In which you'll learn, how to design the solar system size for your house based on the daily average peak sun hours and your electricity consumption (with example). And some other important stuff.
