The rooftop system is 26.23 kilowatts, with a production estimate of 30,029 kilowatt hours/year. This is roughly 20% of the library’s annual load. Rooftop PV panels will reduce 31,500 pounds of CO2 emissions annually.
The charging station is 1.22 kilowatts, with a production of 1,300 kilowatt hours/year. When not being used to charge vehicles, the electricity from the station can be used by the library. This will reduce an additional 1,350 pounds of CO2 annually, for a combined reduction of 32,850 pounds of CO2.
