Who We Are
Southern California’s Solar & Roofing Partner
Sunline Energy is a family‑owned solar, roofing, battery storage, and EV charging company based in San Diego, serving homes and businesses across Southern California. For over a decade, our focus has been to design and install high‑quality systems that deliver long‑term value at a fair price, with clean workmanship and clear communication. Today, we’re recognized as a leading regional solar and roofing contractor, with thousands of installations and loyal customers who refer us to others.
Our Story
From Solar Startup to Trusted Local Contractor
Sunline started with a small team, a few trucks, and a commitment to doing things the right way—even when no one is looking. As we grew, we saw a recurring problem: many customers needed both solar and a new roof, but didn’t want to juggle multiple contractors. So we became a licensed roofing contractor, built in‑house roofing and electrical teams, and invested in engineering so we could handle projects end‑to‑end. The result: one accountable company, one coordinated design, and one team you can call for answers.
