Everyday Energy on Avenida Encinas in Carlsbad has specialized in solar PV and solar thermal systems for the subsidized and LIHTC housing sector since its 2002 incorporation, deploying over 26 megawatts across 174 multifamily properties statewide. Virtual Net Metering design for multi-tenant buildings requires metering diagrams and electrical riser configurations developed in coordination with the architectural planning that Southern California Design Company produces for low-income housing developments. The California Solar Initiative recognized the firm for completing the largest number of MASH (Multi-family Solar Housing) projects in California, a designation reflecting its depth in CPUC rebate processing, housing tax-credit compliance, and lender requirements specific to subsidized multifamily construction. Domestic hot-water infrastructure on those same projects interfaces with the plumbing risers and solar thermal piping that Vanguard Plumbing & Drains installs in high-density residential buildings near Carlsbad's Poinsettia Park. The most complex deployments combine rooftop PV arrays with solar thermal collectors, centralized battery storage, and building-wide VNEM metering across 100-plus-unit multifamily communities.
