Thanks to 200 solar panels installed on top of the 55-unit building, energy stored up during the day will light the common areas in the building (hallways, the recreation room etc.). The panels were installed by SolarCity Corp., the largest installer of residential and small commercial solar systems in the state. This South Los Angeles apartment is one of only two solar facilities in Los Angeles City constructed by the non-profit Los Angeles Community Development Design Center./OW photo by Cynthia E. Griffin.
