Tax Credits

Your Guide to Tax Credit

Here's an example of how the credits may be calculated

SOLAR CREDIT CALCULATION*
System Cost* $5,500
GET Tax $259.16
Gross System Cost $5,759.16
Hawaii Energy Rebate $750.00
Payment upon Completion $5,009.16
Federal Tax Credit (30%) -$1,502.74
Hawaii Tax Credit (35% of system cost) -$1,753.20
Net System Cost $1,753.22

The gross system cost for a hot water system will depend on:

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