What reviewers said

  • 5★ · around February 2026 · the company replied

    We always get our solar plans done with Eco Sun Design and they always do a great job. When we have corrections, they are quick with helping us out so we can submit to the city. Not only do they get our plans done but they also help us with any questions we may have. They go above and beyond to provide a great service.

    I’ve been working with Gayan at Eco Sun Design for about a year for solar plan sets, and they’ve been excellent. Communication is solid, turnaround is reliable, and the designs are clean and accurate. Highly recommend. Looking forward to continuing to work with them.

    I have been collaborating with this organization since 2016 and couldn't be more satisfied. When Gayan Kaluwahandi assumed management of my account a few years back, the partnership was further strengthened. Eco Sun Design continues to be my premier choice for design services. They are highly responsive, incredibly fair, and provide the fastest turnaround times I have encountered in the industry. Besides creating precise designs, they also assist with code modifications and offer valuable design advice. This is a firm you'd want supporting your business!

Topics Google derives from the review text, with how often each appears. A frequent topic is not a good one: “price” turns up in praise and in complaints alike.

What the company says about itself

Taken from its own website. We have not checked any of it, and a sentence on a website is not evidence.

    Its website also mentions free estimate, but not in a sentence we can quote cleanly.

    As Google published them when we last read the listing, not a live check. Ring before you drive anywhere.

    Ordered by how much we can tell you about each, which is not an order of quality. We do not know which of these is better and would not say if we did.

    What we don't know

    • The date above is the newest review we hold, which is not necessarily the newest that exists — we hold a large share of Google's reviews, not all of them.
    • Google publishes no street address for this company, so we cannot say which town it is based in. Valencia is the area its listing was returned for, not an address we hold.
    • We do not verify licences, insurance or bonding. Nothing here has been checked against a state licensing board.
    • We cannot tell you what an installation costs, and we hold nothing about the equipment they fit.
