What drives the number in New Mexico
At 6.3 peak sun hours a day, New Mexico is among the sunniest states in the country. Each kilowatt of capacity delivers about 1,840 kWh a year here, so systems are smaller and cheaper for the same output than almost anywhere else.
Roof space is usually the binding constraint rather than budget. The 270 square feet above is usable south-facing area — chimneys, vents, dormers and north-facing slopes do not count towards it.
