Low-cost modular array-field designs for flat-panel and concentrator photovoltaic systems
This paper describes the design and development of low-cost, modular array fields for flatpanel and concentrator photovoltaic (PV) systems. The objective of the work was to reduce substantially the cost of the array-field balance-of-system (BOS) subsystems and site-specific design costs as compared to previous PV installations. These subsystems include site preparation, foundations, support structures, electrical wiring, grounding, lightning protection, electromagnetic interference considerations, and controls. To reduce these BOS and design costs, standardized modular (building-block) designs for flat-panel and concentrator array fields have been developed that are fully integrated and optimized for lowest life-cycle costs. Using drawings and specifications now available, these building-block designs can be used in multiples to install various size array fields. The developed designs are immediately applicable and reduce the array-field BOS costs to a small fraction of previous costs. Prototype array fields are currently being installed using each of the two alternative building-block designs developed for flat-panel PV array fields.
