Star Solar

What Star Solar does

Star Solar (legal entity Star Power Systems LLC) is a Puerto Rico-based solar energy installer and developer headquartered in Guaynabo, operating as a wholly-owned subsidiary of VRM Companies, a local conglomerate with 40+ years of residential development experience serving over 11,000 families on the island. The company designs, sells, and installs photovoltaic systems across four verticals — residential, commercial, industrial, and utility-scale — using Tier 1 OEM equipment including Enphase microinverters, Tesla Powerwall battery storage, and Unirac mounting hardware rated to withstand 165 mph winds suited to hurricane exposure. Pricing is quote-based per system, with financing provided through a partnership with ENIUM Capital Group offering 100% project funding over 10-25 year terms at interest rates starting at 3.99%, plus a 20-year manufacturer warranty on equipment.

The company's revenue model is primarily one-time system sale and installation, augmented by financing facilitation (via ENIUM) and government-program administrative services. Through its Onergy sub-brand and DDEC partnership, Star Solar processes applications for Puerto Rico's Energy Support Program, which provides qualifying small and medium businesses (PyMEs) with up to $25,000 per installation against a $20M ARPA-funded incentive pool. Distribution is direct and island-wide, with lead generation through the company website, social channels (Facebook, LinkedIn, Instagram, Twitter/X), and Calendly-scheduled free consultations. The go-to-market is consultative sales-led, with the company's positioning built on VRM parent-company credibility, certified installers (NABCEP, SEPA), full end-to-end delivery from energy assessment through LUMA Energy grid interconnection, and a stated ambition to capture more than 20% of the Puerto Rico solar market.
