AZ HB2493

Amends Arizona Revised Statutes Section 42-11054 to clarify that solar energy devices and grid-tied photovoltaic systems designed for on-site consumption add no value to real property when appraised as part of the property.

Creates new Section 42-13056 establishing a depreciation schedule for solar energy devices classified as personal property, with valuations based on taxable original cost minus applicable tax credits and grants.

Specifies a 10-year depreciation schedule with adjusted annual percentages ranging from 3% in years 1-3, increasing to 100% by year 10, using department-prescribed depreciation tables for personal property.

Requires taxpayers owning classified solar equipment to annually report the taxable original cost to county assessors in each county where the property is located.

Mandates recalculation and refund of any excess taxes paid on solar energy devices for tax years prior to the bill's effective date if they were valued under different standards.
