The annual average insolation (energy of sunlight per unit area) striking a fixed solar panel in Buffalo, New York, is 200 W?m?2, while in Phoenix, Arizona, it is 270 W?m?2. In each location, the solar panel converts 15% of the incident energy into electricity. Average annual electricity use in Buffalo is 6000 kW?h at an average cost of $0.15 kW?h, while in Phoenix it is 11,000 kW? h at a cost of $0.09 kW? h.
