The largest, single contributor to the average Hawaiian household electric bill is a hot water heater. 

According to the Hawaii Homeowner’s Guide to Energy, Comfort & Value, published by the State of Hawaii, Hawaiian Electric Company has determined that 40% of the average consumer’s electric bill feeds water heaters. Let our abundant Hawaiian sunshine take that burden off your electric bill by letting it do what it does best, heat things up! No one solution fits every household. Our trained solar consultants can provide you with an analysis that will provide you with the best options for your individual situation.

Solar Hot Water Heating

Using water heated by the sun (which is plentiful), instead of water heated by electricity, can make the single, largest impact on your monthly electric bill. These systems have become only more efficient over the years. Our skilled solar consultants can take care of everything, from design and permitting to successful, professional installation.  

Our Solar Hot Water technicians have a minimum of 10 years of experience installing and maintaining solar water heating systems on Oahu.  Solar Cool Hawaii is a participating contractor with Hawaii Energy’s solar hot water program.


The Empire collectors’ large diameter Type-M copper riser tubes allow the Empire collector to be used in glycol forced circulation, drain back, or open-loop system configurations depending upon the climate and application.



Blazing Tubes solar hot water system is a self-contained system mounted to your roof that produces 80 gallons of solar-heated-water daily.  Blazing Tubes sends it through your gas heater and reduces your heater usage by 80% and the payback can be in as little as 3 years.
