This paper presents research results to develop a minimal cost photovoltaic array tracking structure. Objectives of the project were to (1) employ a modular design based upon multiple point foundations, off-site assembly, and commercially available materials; (2) offer performance improvements over horizontal one-axis trackers by tilting the axis of rotation; (3) verify design performance, and cost goals through prototype construction and operation. Each of these objectives was accomplished beginning with design activities in early 1993 and culminating with construction of commercial trackers in early 1995. The Delta Trackers{trademark} offer dramatic reduction in PV energy production costs ({cents}/kWh) through lower balance-of-system costs and improved performance.
