The 100 kW system consists of the photovoltaic array, the inverter/control subsystem, the building and utility interface, and the monitoring subsystem. The photovoltaic array consists of 40 separate subarrays of 80 photovoltaic modules each (5 parallel by 16 series), deployed in rows on the southerly facing slope north of the school building. Typical operating voltage is 250 V. The wiring scheme permits individual modules to be disconnected without a radical change in subarray output current. Power is transmitted at 4160 V from the inverters and a step-up transformer to the main 4160 V utility feed line in the school. Separate metering measures power bought and sold. At the optimum tilt angle of 40/sup 0/, the array provides 116 MWh of ac energy annually, or 8% of the school load. A fault detection and isolation scheme which can find faulty modules is incorporated into the monitoring subsystem. Safety during installation, operation and maintenance was a major consideration in system design.
