Treepublic started in a garage in 2008, founded by individuals who loved nature and grew frustrated searching for a straightforward, no-nonsense solar installer in Los Angeles. After failing to find one, they decided to do the work themselves—beginning with a single solar patio project and building from there. What started as a personal solution has grown into one of Southern California’s most respected solar installation companies, now headquartered in Hawthorne, California, where the team serves homeowners and businesses across the state. The company’s founding story reflects a personal connection to energy security: founder Omar Nasser spent time in Lebanon during his teenage years, experiencing electricity for as little as six hours per day. That experience shaped Treepublic’s mission to provide reliable, clean energy solutions that give people peace of mind and freedom. Today, Treepublic has installed nearly 50 megawatts of solar panels and over 20 megawatt-hours of battery storage across California, from off-grid cabins to Fortune 100 corporate campuses. The company earned recognition as one of Inc. Magazine’s Top 10 Fastest Growing Private Energy Companies in the United States in 2020, ranked #207 on the Inc. 5000. The Los Angeles Times awarded Treepublic the inaugural Best Solar+Storage Company in the Southland, and the company has been featured in Bloomberg, The New York Times, and Solar Power World. Treepublic operates multiple locations throughout Southern California, including Hawthorne, Bel Air, Northridge, and Upland, ensuring local presence for California homeowners. As a solar installer in Hawthorne and across the greater Los Angeles area, Treepublic brings deep knowledge of local permitting, utility programs like those from LADWP and Southern California Edison, and California’s ambitious renewable energy mandates. The company holds California Contractor State License Board (CSLB) License #996593 and employs NABCEP-certified installation professionals, placing them among the 2% of NABCEP-certified solar companies in California. Treepublic’s services span residential solar installation from 3kW to 100kW+, commercial and industrial projects up to 10MW, battery storage systems from brands like Enphase, Tesla, Sol-Ark, and Schneider Electric, custom solar carports and patio covers, and EV charging station installation. The company is an Enphase Platinum Installer, one of the few nationwide, and has completed nearly 1,000 permitted projects according to BuildZoom. Treepublic’s philosophy centers on education first, installation second—ensuring California homeowners understand how solar energy works, what incentives are available, and how battery storage can provide backup during outages or offset time-of-use rates. For residents considering home solar in Hawthorne and surrounding California communities, Treepublic offers a locally rooted team that understands the region’s climate, architecture, and energy challenges, from managing HOA requirements to navigating California’s Net Energy Metering 3.0 policies.
