Transferring the power back to you.
A local Santa Monica solar company raising the bar on quality — without raising the price.
Premium solar, without the premium markup.
Sunko Solar was founded on a simple idea: Southern California homeowners deserve premium solar without the premium markup. We design, install, and monitor every system in-house — no lead-selling, no sub-contracted crews, and no high-pressure sales.
Our panels are tested to outperform industry standards by roughly a decade, and every install is backed by a 25-year warranty with a maintenance plan. From your first bill review to the day your system powers on, you work with the same local Santa Monica team.
Today, Sunko powers thousands of SoCal homes and businesses — a reputation we've built almost entirely on referrals.
Built on quality, ownership, and trust.

The owner you actually talk to.
Marco Iwabuchi founded Sunko to run solar the way it should be: hands-on and honest. When you call, you reach the owner — not a call center. He leads every project personally, from explaining the numbers before you sign to taking the lead when the city or utility makes permitting difficult.
It's an approach customers notice — many mention that Marco gave them straight advice on systems he didn't even install.
“I'll give you the honest numbers, take the lead when the city makes it hard, and stand behind your system for the next 25 years. That's a promise.” — Marco Iwabuchi, Founder & Owner
What our customers say.
“Sunko Solar is a breath of fresh air. It is so hard to find trustworthy solar companies in Los Angeles… They were excellent to work with and made sure to take the lead when we had complications with the city. Incredibly rare to find such genuine business practice nowadays.”
“Outstanding company. I looked for years to find a solar company that I trusted and felt right about. SUNKO checked all our boxes — great communication, great price, and quality work. I will recommend my friends and family to SUNKO solar.”
