PV Value Tool (USA)

Spreadsheet tool to determine value of new or existing photovoltaic (PV) system

This spreadsheet tool developed by Sandia National Laboratories and Solar Power Electric™ is intended to help determine the value of a new or existing photovoltaic (PV) system installed on residential and commercial properties. It is designed to be used by real estate appraisers, mortgage underwriters, credit analysts, real property assessors, insurance claims adjusters and PV industry sales staff. For appraisers, the inputs specific to PV in the Residential Green and Energy Efficient Addendum can be used as inputs to PV Value™. Valuing a PV system is done using an income capitalization approach, which considers the present value of projected future energy production along with estimated operating and maintenance costs that are anticipated to occur during the PV module power production warranty timeframe. This tool was created with Microsoft Excel® 2007, and works with both Excel® 2007 and 2010.
