HISTORY

Founded in 1973 in Honolulu, Hawaii and incorporated in 1975, The Solaray Corporation (our parent company) is one of the oldest renewable energy companies in continuous operation in the world. The Solaray Corporation consists of Inter-Island Solar Supply, Pacific Liquid and Air Systems, and the SunEarth Corporation, our solar collector manufacturer.

Inter-Island Solar Supply has represented the finest and most respected manufacturers in renewable energy. From our humble beginnings in 1973 helping build small scale off grid solar systems to the present day 100+ kilowatt commercial PV projects we have been the go-to distributer for solar products. We are the only solar parts distributer in Hawaii that has the experience, inventory, and local knowledge to fill any solar need. Whether it’s a solar + energy storage setup, a multi-collector solar hot water system, or a large scale commercial pump station we have what you need.

  • Inter-Island Solar was extremely helpful to the point of even loaning me a tool one time to do a job on my home. Cully Judd, the founder, is an icon in the local solar industry.

  • When it does go bad, I will definitely call Inter-Island for their recommendation. The thing I appreciate most is, you can tell when you are working with people who know their stuff. These people know their stuff. I like that!
