City of Del Mar Solar & Storage Demonstration


As California cities seek greater energy efficiency in municipal buildings to help meet greenhouse gas reduction goals and climate action plans (CAP), it is increasingly important to develop strategies that maximize the benefits of combining solar and energy storage systems.

CSE assisted the city of Del Mar to install high efficiency photovoltaic (PV) panels and state-of-the-art energy storage equipment in a new civic center complex. The city received a $389,000 grant for a 62.5-kilowatt PV system and a 100-kWh energy storage system from the California Energy Commission under a program to demonstrate the effectiveness of these systems in municipal and commercial buildings. Data on the system’s performance will be widely distributed to help overcome adoption barriers and concerns, including return on investment, long-term energy costs and system efficiency in a coastal environment with more clouds and fog.
