Systems Long Term Exposure program: Analysis of the first year of data

While indoor accelerated testing of products is important for development, it is equally important to conduct field-testing to determine performance and degradation under real world conditions. To address this need, Sandia has developed an outdoor small systems evaluation laboratory. The Systems Long Term Exposure (SLTE) project spans three geographic locations: one in a hot/dry climate, one in a hot/humid climate and one in a cold climate. Identical systems representing three commercial technologies are installed at each location. In this paper we present the results and analysis from the first year of monitoring of these systems.
