    saw an ad and contacted naga. he showed up, listened to my concerns, and guaranteed his help even though my system was installed by someone else. my original installer had made numerous programming mistakes which naga was able to fix from his own home computer. he then dropped by to talk about my system and hook up an accessory that was hooked up, but once again not programmed correctly. in a couple minutes he had it fixed. wish 8 had found him first. excellent experience.

    IMPRESSIVE from the initial site visit to install! The install was done in 1 day! Our driveway is difficult and our roof is steep and they didn't even flinch, we have had others out to assess and it was a big deal also stated job would take weeks. Naga and his team are PROFESSIONAL, RELIABLE, his work is IMPECCABLE and AFFORDABLE.

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.

  • Established

    “I've been doing solar installs since 2021. I worked as the foreman for Kai…”

Its website also mentions warranty and 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. Pahoa 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.
