Was not happy at all with this installation. Two (yes, two) rows of wrong holes in my roof after a solar install. One row is still there under the panels, a row of bolts that was clearly installed incorrectly. And the second row was patched, very poorly, with tar, and it took literally months for them to come back and do a little better job patching their incorrect holes punched through my roof. They ended up trying to color match the paint on the visible holes but that didnt work very well either. The solar is otherwise working great but punching extra holes, not telling me, and then making me insist on fixing these holes in a reasonable way, is not ok.

We hired Mattos Electric to install solar on the Naniloa. After working with them for a few months I can say with certainty that they are one of the hardest working crews I’ve had the joy of working with on Big Island. Professional, reliable, knowledgeable, and they get it done. If you hire the cheapest contractor you’ll get the cheapest work. If you hire Mattos you’ll get the best value for your $.

Mattos did a solar install for us in Orchidland. That resulting damage was extensive. Holes were put in the metal roof without adequate sealant. This was discovered when water came through our ceiling in numerous places. The drywall in the attic was a mess. I contacted Mattos on MANY occasions asking them to fix the damage. They are studiously ignoring me. When things went south, they fled south as well.

Great customer service at a very reasonable rate, mahalo dudes!

I called Mattos Electric to see if a technician would be able to come to my home & take a look at my solar inverter that had stopped working. After speaking to the dispatcher, a skilled technician called me & walked me through how to reset the solar inverter. I was very impressed with the quick professional service. I will definitely call them in the future any time I have electrical issues & need service at my off the grid home. Highly recommend this company.

Very knowledgeable
