What Stellar Solar Commercial does

Stellar Solar Commercial, founded in 1998 and headquartered in San Diego, California, designs and installs commercial and residential solar photovoltaic (PV) and battery energy storage systems (BESS) primarily across California and, on a project basis, throughout North America. The firm operates as a vertically integrated C-10 licensed electrical contractor with in-house engineering, project management, electrical, and installation teams, executing projects spanning roughly 7 kW residential and small-commercial arrays up to multi-megawatt commercial and industrial installations (largest disclosed project: 2.3 MW at Shaw Distribution Center, Methuen, MA; 6.18 MW solar array at Palomar College). Its technology stack combines industry-standard PV modules from SunPower, Hanwha Q Cells, SMA inverters, and SolarEdge optimizers with integrated storage from Tesla Powerwall, BYD, Enphase, and FranklinWH, layered over a proprietary non-penetrating commercial mounting system (design patents held by President Kent Harle).

The business generates revenue primarily through one-time turnkey project contracts covering design, engineering, permitting, installation, and commissioning, supplemented by 1-2 year recurring service and monitoring contracts and professional services for federal (ITC) and state incentive navigation. The go-to-market is a direct enterprise field-sales motion targeting ten vertical segments — auto dealerships, healthcare, multi-family housing, government/municipal, education, faith-based, non-profits, small-to-medium businesses under 100kW, large commercial/industrial 100kW+, and carports — supported by content marketing, SEO, Lunch-and-Learn community programs, and authorized-contractor channels (notably the San Diego Community Power Solar Battery Savings Program). Distribution is augmented by referral networks and Tesla Certified Premier Installer status.

Notable institutional customers include the Salk Institute, Cedars-Sinai Hospital, Los Angeles Unified School District, Loyola University, City of Anaheim, Vandenberg Air Force Base, US Foodservice, and Shaw Industries. The firm is privately held and wholly owned by its founding team, with no disclosed external funding, M&A activity, or financial reporting; cumulative reach is 16,000+ installations and 25+ MW of commercial solar capacity installed in California since founding.

Revenue model

1. Commercial Solar Installation Sales: Design, engineering, permitting, and installation of custom solar PV systems for commercial, industrial, government, and multi-family clients. Revenue is generated through one-time project fees for system installation, typically structured as a full turnkey contract covering the entire project lifecycle from site assessment through commissioning.
2. Battery Storage and ESS Installation: Installation of battery energy storage systems (BESS) integrated with solar PV, including systems from Tesla Powerwall, BYD, Enphase, and FranklinWH. Revenue is one-time for installation, with ongoing monitoring and service contracts available.
3. Commercial Service and Maintenance: Ongoing commercial service and maintenance programs including 1-2 year annuity contracts with monitoring, site assessments, reporting, and custom emergency service offerings. Revenue is recurring through service contracts.
4. Federal and State Incentive Navigation Services: The company guides clients through accessing ITC, PTC, accelerated depreciation, net metering, and state/local incentives, which can effectively reduce project costs by up to 55-75%, supporting sales conversion.

Core offering

Stellar Solar Commercial designs, engineers, permits, and installs custom commercial solar photovoltaic (PV) and battery energy storage systems ranging from sub-100kW small business systems to utility-scale projects exceeding 2MW. The company delivers turnkey installation services across rooftop, ground-mount, and carport configurations for commercial, industrial, government, educational, healthcare, multi-family housing, auto dealership, and faith-based clients, with optional ongoing service and maintenance contracts.

Product overview

Stellar Solar Commercial offers a unified portfolio of commercial solar energy solutions centered on three core offerings: commercial solar installation services spanning multiple property types (auto dealerships, healthcare, multi-family housing, carports, faith-based, government, education, non-profits, and businesses under 100kW and 100kW+), battery storage systems for energy resilience and peak-shaving, and commercial service and maintenance programs. The company operates as a single integrated service offering rather than a modular software platform. Projects are customized for each client, and battery storage is typically offered as an integrated component with solar installations rather than a standalone product.
