The tax credit shall be claimed against net income tax liability for the year in which the energy system was purchased and placed in use in Hawaii. Tax credits that exceed the taxpayer's income tax liability may be used as credit against income tax liability in subsequent years until exhausted. The State Director of Taxation may require the taxpayer to furnish reasonable information to support the claim for credits. Additions to existing systems and new systems for second homes qualify for this credit. However, repairs to existing systems do not qualify.
Some restrictions apply.
