Solar Water Heating
A simple, but important first step towards big energy savings.
Did you know the largest energy hog for most homes in Hawaii is the electric water heater, especially if you don’t have AC or a swimming pool? A solar water heating system harnesses the sun’s energy to heat water, so your water heater uses less electricity to do the same work. You'll save energy and save money on your electric bill for years to come!
Start saving up to 40%
For families of four or more, installing a solar water heater can save you up to 40% on your electric bill (around $600) per year. With those savings, imagine what you could buy with that extra money: 15 bikinis, 800 lbs. of rice, 750 malasadas or 200 pairs of slippers!
Use our solar water heating savings calculator to find out what your family and home could save.
