City of Chula Vista
Home MenuPortable Solar and Battery Lending Program
The city is introducing a portable solar and battery lending program for community members to use clean electricity on the go and, when paired with a solar panel, they can create clean, free electricity to help reduce energy bills. This pilot program was funded with a grant from San Diego Community Power with the goal of increasing the use of clean energy and reducing pollution.
