A1 Sun Inc.

At A1 Sun Inc., we help Berkeley homeowners and businesses across the East Bay go solar with systems designed around their roofs, their goals and their energy use. Our team handles every stage, from the first site visit and clear proposal through permitting, installation and coordination with PG&E, so each project moves forward on schedule.

We pay close attention to the details that matter, including careful panel layouts that make the most of challenging roof geometry and work that coordinates smoothly with roofing companies when a new roof is needed. Many of our clients choose battery backup along with their panels, and we're happy to walk them through monitoring options so they can see how their system is performing.

Our pricing is straightforward and competitive, and we aim to be honest and communicative from start to finish. We also take pride in the small-business approach we bring to every job, giving each household the personal attention a project of this size deserves.
