About R.O.I. Solar inc
R.O.I. Solar Inc. is a family-owned, founder-led solar installation company based in Lodi, California, serving homeowners across the Central Valley, Sacramento region, and Bay Area within 100 miles of Lodi. Founded in 2008, the company has completed more than 3,500 installations and holds a 4.9-star Google rating. Unlike franchise-style solar companies, R.O.I. Solar uses exclusively its own licensed electricians and solar technicians—no subcontractors—ensuring consistent quality from permitting through installation. The company specializes in solar panel systems combined with battery storage, an approach it emphasizes as essential under California's NEM 3.0, which dramatically reduced grid export credits. R.O.I. Solar is a certified installer for Tesla Powerwall, an Enphase Platinum Installer, and a Sigenergy Diamond Installer, and holds CSLB license #1082435 with C10 and C46 classifications. Custom system designs are optimized for self-consumption under NEM 3.0, with projected payback periods of 7–10 years and potential lifetime savings of $40,000–$80,000 for a typical Central Valley home. Zero-down financing is available. The company also services systems installed by companies that have since closed, including former customers of Freedom Solar and Bright Energy.
