Luminalt

Founded in 2004 by Jeanine and Noel Cotter, Luminalt is a locally owned San Francisco-based company specializing in designing and installing solar photovoltaic panels and battery energy storage systems throughout the Bay Area. Renowned for its customer-centric approach, Luminalt distinguishes itself by conducting comprehensive on-site analyses rather than relying solely on satellite imagery—ensuring tailored system designs that address each property’s unique characteristics. Their experienced team manages every aspect of a project—from initial consultation through permitting to final inspection—delivering turnkey solutions that minimize surprises or costly change orders.
Luminalt has earned recognition as one of San Francisco’s leading solar installers due to its commitment to quality workmanship, community involvement (including installations for local nonprofits), deep knowledge of local building codes/permitting requirements, and strong relationships with architects/builders. The company emphasizes supporting local jobs through hiring/training initiatives tied to community organizations. With hundreds of successful installations across residential rooftops as well as commercial properties—and an emphasis on integrating battery storage for energy resilience—Luminalt continues to play a key role in advancing clean energy adoption across Northern California.
