Cobalt Power Systems

What Cobalt Power Systems does

Cobalt Power Systems Inc. is a Mountain View, California-based solar photovoltaic (PV) design and installation company founded in 2003, operating exclusively in the San Francisco Bay Area across 12+ cities including San Francisco, San Jose, Palo Alto, and Mountain View. The company delivers turnkey residential, commercial, new home, and multifamily solar systems integrated with energy storage (Tesla Powerwall, Enphase, SunPower/SunVault) and EV charging equipment, holding Tesla Premier Certified Installer and SunPower Elite Dealer (first in the U.S.) designations. Its technical differentiator is in-house engineering for complex urban installations—including custom anchor systems and seismic ballast design for post-tension concrete roofs—supported by 14 installation teams and 32 service trucks operating from a 10,000 sq ft facility. As of the January 2025 SunPower acquisition LOI, the company had 96 employees and approximately $35 million in annual revenue, with more than 4,000-4,500 PV systems completed cumulatively.

Cobalt generates revenue primarily through one-time project-based installation fees for solar and storage systems, supplemented by hardware sales (panels, inverters, mounting equipment, EV chargers), financing facilitation, solar leasing subscriptions, and ongoing maintenance contracts. Pricing is quote-based and varies by system size and complexity, with typical mid-sized residential installations in the Bay Area ranging $15,000-$25,000 and battery additions $10,000-$18,000 per unit. The customer base is anchored by 4,000+ residential homeowners across the Bay Area, with select enterprise commercial accounts including Santa Clara University (1.2 MW project), San Francisco Waterfront Plaza (220.9 kW), and Fortinet.

Following the $12 million all-equity acquisition by SunPower Inc., which closed in February 2026, Cobalt operates as a standalone subsidiary integrated into SunPower's New Homes division alongside Multifamily and Light Commercial segments. The company retains its own brand, sales motion, and installation teams while gaining access to SunPower's national supply chain, capital base, and cross-selling opportunities for premium products such as the SunPower Monolith 470-watt bifacial panel developed through a joint development agreement with REC. Kapil Rai was promoted to EVP of the New Homes division to oversee integration and the projected $100 million project pipeline.
