This is the last spreadsheet supported version of PV Value®. It will be available through August 30, 2014.
This spreadsheet tool developed by Sandia National Laboratories and Energy Sense Finance 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.
Version 1.1 is now available and can be used on both Microsoft Windows and OS X operating systems. It works with both Excel® 2007, 2010 and 2103 for Windows, and Excel® 2011 for Mac. After filling out the required form you can download the tool and user manual describing how to use the tool and changes made for this version. This information will be used to notify you of updates to PV Value®.
