Hawaii: Results of Three Years of Solar Obligation

Submitted by Baerbel Epp on September 3, 2013

Since Act 204 “mandating” solar water heating systems on all new single-family dwellings came into force in January 2010, the number of new residential houses equipped with a solar water heater has risen to 75 % in Hawaii. This is the conclusion from the statistics published by Hawaiian distributor Inter-Island Solar Supply (IISS). Before the mandate, only 40 % of the new residential homes in Hawaii had solar water heaters, estimates Ron Richmond. The Business Development Manager of IISS and former member of the Board of the Hawaii Solar Energy Association (HSEA), however, thinks that there is still room for improvement: The new houses require no independent third-party inspection, because homeowners do not receive any funding from local utilities.

 hawaii landscape” Every fifth building permit for new single-family houses in Hawaii included a tankless gas water heater in the first half of 2010. This is a rather large share, if considered that Hawaii has “mandated” solar thermal water heaters since the beginning of 2010.
