Comparison of Predicted to Measured Photovoltaic Module Performance

To accurately predict the electrical performance of photovoltaic modules computer simulation models are essential. Without such models, potential purchasers of photovoltaic systems have insufficient information to judge the relative merits and cost effectiveness of photovoltaic systems. The purpose of this paper is to compare the predictions of a simulation model, developed by Sandia National Laboratories, to measurements from photovoltaic...
