SunEarth and Inter-Island Solar Supply, our Hawaii distributor, teamed up to provide solar water heating systems for 476 homes at the Helemano Military Reservation located in central Oahu. Grand Solar and Pacific Mechanical, both of Honolulu, served as the primary installation contractors. An additional 134 systems were installed by a third contractor. The entire 610 home job is one of the largest solar water heating projects ever undertaken in the United States.
SunEarth, Inter-Island and Pacific Mechanical also collaborated on two concurrent Army retrofit projects for 40 additional homes at the Waianae Army Recreation Center as well as a commercial system for the Wheeler Army Airfield Fire Station.
Estimated annual energy savings from the project, which was completed in 2002, is a healthy $395,000. Hawaiian Electric Co.’s residential efficient water heating program provided the Army with $610,650 in demand-side management rebates.
