The two numbers that matter
Electricity price: 16.1¢/kWh, below the national state average of 19.3¢. Every kilowatt-hour your panels make replaces one you'd buy at this price, so higher prices mean faster payback.
Sunshine: 6.4 peak sun hours a day, more than the state average of 5.0. Each kW of panels here makes roughly 1,828 kWh a year after real-world losses.
