Site Characterization Report

Building Overview

The Walmart Supercenter sits between the I-210 and I-10 freeways in Los Angeles County, just south of Azusa, in California Climate Zone 9. It includes standard retail space with several in-store centers including auto care, photo, vision, garden and pharmacy and a grocery sales area with a deli and bakery and a McDonald’s restaurant.

Originally constructed in 1997 as a standard Walmart, it was renovated to a supercenter in 2010, adding the grocery section with a deli and bakery. A 500kW-AC solar photovoltaic (PV) system was installed in 2007 to help reduce electric consumption from the grid.

Existing Solar Array and Battery Storage

A 500kW-AC solar PV system was installed in 2007. The PV panels cover about 60% of the roof’s surface and generate about 867,437 kWh annually. Battery storage was installed in 2019 using Tesla’s Powerpack 5.3 model. It has a 300 kW power rating and a 510 kWh energy capacity.

Surrounding Community

The test site is located in the City of Covina, California, which is a part of Los Angeles County and lies about 20 miles east of the City of Los Angeles with a population of about 47,000 people as of the 2000 census. Areas of Covina and surrounding communities are identified in CalEnviroScreen 3.0 as disadvantaged communities. Education and community outreach will take place on-site to reach underserved populations with information about energy savings and introduce integrated energy efficiency strategies. Educational opportunities will be designed to empower disadvantaged community members to understand their role in energy savings and provide information to increase energy savings at home and work, thereby extending the impact beyond the project site.
