  1. A shared battery in a neighbor's garage
  2. A group that pools buying power for rooftop solar ✔
  3. A utility that only sells solar power

Why: Co-ops let neighbors shop together for rooftop systems. Acting as a group helps attract competitive bids from installers.

Huh, didn't know that: Per DOE, solar co-ops are free to join and have no binding commitments.
