Sandia National Laboratories Photovoltaic Project

Schedule: April 2011
Project Manager: Todd Merchant

The Sandia National Laboratories Photovoltaic Project is conducting a Systems Long Term Exposure (SLTE) experiment, specifically designed to field small grid-tied systems in three diverse climates (New Mexico, Florida and Vermont) for the purpose of measuring degradation of the systems.  This is a controlled study of the PV modules having some level of baseline testing prior to installation.  In order to measure low levels of change in a relatively short period, well characterized data collection hardware and best practices will be used. 


The University of Vermont, in coordination with New Mexico State University (NMSU), will develop outdoor photovoltaic test capabilities in support of a Sandia National Laboratories research project.  Work includes administrative, engineering and construction tasks required to install, make operational, and collect operating data from a number of 1KW grid-tied systems.  These systems will be monitored by NMSU to measure system degradation rates with the expectation that these rates will be representative of systems deployed in climates with periods of severe cold, such as Vermont.
