Solar Kauai Overview

Solar Kauai is the longest-running solar company on the garden isle in Hawaii. Established and certified in 1982, Solar Kauai has built solar water heating and electricity systems at over 8,500 homes and several commercial buildings.

Solar Kauai has been run by the same family for almost 40 years, dedicated to serving the people of Kauai with high-quality support and services.

Solar Kauai was one of the first companies to get a C-60 License, enabling it to conduct business on all of the major Hawaiian Islands, Molokai, Lanai, and Niihau. As a result, the business is often regarded as a forerunner in installing solar electric (PV) systems in Hawaii.

A system that’s easy to install and doesn’t break the bank might provide you with all of the electricity you need to keep your home running efficiently. When the sun is out, the system produces electricity that may be utilized in your home, and any additional power produced can be sold to the local utility company (KIUC).

While Solar Kauai does not provide much information regarding its commercial solar service, the company is linked with several well-known business projects across Hawaii. 


Additional services:

  • Water Heating Systems: Solar water heaters may get your water to a comfortable temperature using the sun’s energy. Switching to a solar water heating system from a conventional electric water heater would drastically save your monthly electricity costs and provide your home with an endless hot water supply.

Most solar water heating systems need roof installation. Solar Kauai can provide a customized solution that will work for your home.


Installation costs and process


A typical 6000-watt (6 kW) solar system in Hawaii costs $11,197 once the federal solar tax credit of 30% is applied. This is the typical price for a solar panel installation in Hawaii.

Solar panel installation costs will change depending on factors like your geographic location and the current power use of your property. Therefore, information on the cost of installing solar panels must be customized to each individual’s circumstances before it can be useful.

Previous customers have indicated that Solar Kauai’s costs are extremely competitive and that the family-run business maintains excellent customer service satisfaction levels. Here’s an example:

“I received 5 quotes from top 5 solar companies in Kauai. Ended up going with solar Kauai for many reasons. First they have been doing solar on island for 40 years. When I called Elliot he was not trying to sell me, he was extremely informative and asked all the right questions to make sure I was taken care of and I understood everything. They use all the top notch technology with Solar Ark inverters and high efficiency REC panels. Their quote was the lowest out of the 5 BY FAR not becuase they use cheap products or hire cheap labor but becuase its ran by a family owned business with not a lot of overhead.”
