Under California’s Global Warming Solutions Act of 2006 (AB 32) cities are required to establish a comprehensive program to reduce greenhouse gas emissions from all sources to fight global warming. The city of Woodland’s 2017 Climate Action Plan provides strategies to move into compliance with AB 32, including moving to renewable energy sources. Woodland decided to control its long-term energy costs by powering a variety of its buildings with on-site solar energy. The challenge was doing so in a way that did not impede normal city operations or reduce the level of service to its citizens.
After a competitive RFP process, Woodland awarded a 2.46 MW portfolio of solar projects to HOLT Renewables, which has extensive experience working with local governments nationwide. The project covers 80% - 90% of the energy demand for 5 of the 6 facilities. Construction included of six separate systems using Hanwha Q-CELLS panels, and Solectria and SolarEdge inverters, installed at the City Hall, Community & Senior Center, Public Library; Municipal Services Center, Police Department, and Water Pollution Control Facility. Installations included 1.3 MW of carports, rooftops, and shade canopy installations, as well as 1.1 MW of ground-mount installations. At each site, solar had to allow operations to continue as normal, and visually and structurally complement the site.
