Hello,

I'm wondering for the upstate NY area how many kWh of electricity 1 kW of solar PV generates over a year. I've heard that under optimal conditions (southern exposure, etc) it is 1.1 kWh/W/year, but I wanted to confirm this.

This would appear to be the key number necessary to figure out approximately the size of a solar PV system you need based on your electrical usage. Take kwh used in a year and divide it by 1.1 to get the approximate size of the system you need (under optimal conditions).

Thanks,

Karim
