Washington State PV Array 

I like solar calculators, and this is an interesting one to explore.

The PV Watts1 calculator from the National Renewable Energy Laboratory (NREL) is a simple solar calculator that can help you figure out how much electricity you can generate with a PV system at many locations around the world. (Disclaimer here.)

When you use the calculator, it gives you a measurement of solar radiation in kilowatt-hours per square meter, which is also known as peak sun hours. (Here’s a very detailed explanation of that concept from the U.S. Department of Energy.)  

I used the calculator to compare peak sun hours and kWh of electricity generated for several different locations. You should know that I used all the default settings on the calculator, so the measurements below assume a 4 kilowatt PV system and a fixed tilt, south-facing PV array.
