Chief Appraiser Says
Reading the actual guideline text below — never a general AI guess
Here's what we found in these passages: The excerpts shown here don't actually explain what "kw" means or how it measures solar system size. The passages reference kilowatts in their titles and discuss solar components, costs, and how solar systems are classified as real or personal property for appraisal purposes, but they don't define the term itself or explain how kilowatts work as a sizing metric. To get that specific technical explanation, you'd need to see the full content of the documents cited, particularly the Solar PV: Kilowatt & System Basics Reference and the sections on heating system types and mechanical details.
Straight from Solar PV: Kilowatt & System Basics Reference (EIA/NREL, NEC 690.12), UAD 3.6 / URAR (FNMA), Solar PV: Components & Typical Installed Costs (NREL, LBNL, EnergySage, BloombergNEF), Clark County Title 30 Unified Development Code and Zoning, Solar PV: Real vs. Personal Property & Valuation (Fannie Mae, Freddie Mac, FHA, VA, UAD 3.6), and HUD/FHA Single Family Handbook 4000.1 — nothing added.

This covers what solar is or isn't — not what it's worth. For what systems are typically
built from and typically cost (cited to NREL, LBNL, EnergySage, and BloombergNEF, separate from
any value question), see the components & cost reference →
