A photovoltaic system's annual energy production per unit area is a function of collector efficiency and the incident solar radiation. The incident energy is determined by geographic location and the type of mounting structure: fixed or tracking. Because of significant differences in the solar energy available to various structure and tracking concepts, it is possible to achieve equal energy cost for widely varying array field prices. The authors' analysis of some of these array options using recent estimates for balanceof-system costs shows that two-axis tracking of flat panel collectors results in lower energy cost than fixed arrays, even at low module prices.
