Sharing the Sun: Community Solar Project Data (National Laboratory of the Rockies)
National Laboratory of the Rockies (NLR), U.S. Department of Energy
Our counts and capacity (MW-AC) of community solar projects by state, from the laboratory's project list: projects serving customers by who markets the subscriptions, capacity by year of interconnection, and the capacity the laboratory tracks as in queue in key states.
Not included: No copy of the project list: its license keeps the laboratory's name from any use that could read as endorsement, so only our own computed figures are published. In-queue capacity is market tracking, not a registry, and has no project counts.
