    Noah was super helpful even with a small storm prep job. I was treated like a valued customer. Don’t even think about going anywhere else for Sultan equipment or advice!

    I needed a new motor for my solar attic fan. It was still under warranty and I got a new motor. Big Mahalo to the staff at Inter-Island Solar Supply.

  • 5★ · around September 2017 · the company replied

    I needed a new release valve for my solar panels when I came home to water draining off the roof. The staff at Inter-Island Solar Supply were kind, helpful, knowledgeable and the had the part. Made my day!!! Mahalo!

Reviewer names are not published here. Negative reviews are shown first because they are the ones a listing hides, not because they are more representative.

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.
  • 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.
