One of the best things about this tax deduction is that it can be combined with federal alternative energy tax breaks that can allow you deductions of up to 30 percent of the cost of the system, with no limit on the amount; so even if your solar panel system exceeds $20,000, you can still enjoy federal tax deductions.
This particular deduction is claimed on the Idaho Supplemental Schedule, Form 39R, and you can contact the Idaho State Tax Commission at http://tax.idaho.gov for more details.
