Title

Flat-Plate Pv Array Performance.

Abstract

A tracking photovoltaic research facility that began operation in March 1985 has been used to test and compare, on a side-by-side basis, four matched 500 peak W (W//p) photovoltaic systems operating in the four tracking modes: two-axis; single-axis 'SMUD' type (i. e. , rotation about a fixed north-south axis; single-axis azimuth tracking (i. e. , rotation about a vertical axis at fixed latitude tilt); and fixed orientation (south facing at latitude tilt). Measured and predicted performance of the four tracking arrays for one year (March 21, 1985 to March 20, 1986) is reported. Sandia National Laboratories' code PV-FORM was used to predict the performance of the four arrays. Mean bias errors between the measured and predicted insolation were found to be a function of season. The application of this seasonal mean bias error to the predicted results produced excellent correlation between the measured and predicted performance. Using the measured data, the economics of the four modes of operation are considered.
