Sunny is the City of Aspen's portable solar PV system designed to power portions of local special events. Sunny is sponsored by a grant from CORE, and is maintained and run by the City of Aspen ZGreen program.
It provides 500 watts of power for 7-8 hours or up to 2,500 watts for 1-2 hours. The system includes batteries for power storage, educational signage and a cord to connect it to the grid for back-up power. The back-up grid power option ensures that events won't lose power if their devices use more than expected or if it's a cloudy day.
