This final report describes the procurement, fabrication, assembly, installation, and test of a fixed flat-panel photovoltaic (PV) array field composed of modular 10 kWp building blocks. Implementation of this hardware program was in strict adherence to the designs developed under a prior Sandia contract for an array field optimization and modularity study for intermediate power (20 to 500 kW) size systems. The basic objective of this program is to verify the balance of systems costs developed under the prior study contract. Each of these modular building blocks of a nominal 10 kWp was installed at the Photovoltaic Test Facility of Sandia National Laboratories, Albuquerque, New Mexico. Major features of the balance of systems incorporated +-200 Vdc bipolar circuitry, a low cost hybrid structure/foundation featuring a frameless panel and self-grounding foundation, and a power collection center for housing the modular system controls and protection circuits. An economic analysis of the completed project showed that the objective was realized for achieving an installed, low-cost balance of systems for an intermediate power, flat-panel photovoltaic array field.
