*Disclaimer: This example is for illustrative purposes. The costs vary upon the type of unit installed and these numbers should NOT be considered to be tax advice. Consult with your tax advisor, IRS, or State of Hawaii tax office to determine how these credits  should be calculated or your own individual situation. The State of Hawaii has a $2,250 cap on the tax credit.

Note: You will only be able to receive the rebate if you use an approved participating contractor for installation. Perrin Plumbing LLC handles all of the rebate paperwork.

The cost of your solar water heater system will depend on several factors:

1. How many people live in your household.
2. Where water heater tank is located now & how accessible is that area.
3. The area of the island that your house is located. (so we can determine your sun zone)
4. If your house is a one or two story building.
5. The type of existing roofing material.
6. How south your roof faces and the angle of your pitch.

for a solar site assessment and estimate.
