PV System-equipped Logistics Facility Contributes to Local Community, Environment (page 5)
Power generation outperforms estimate by more than 10%
Solar panels were attached to the corrugated roof by clasps, while PV inverters and the grid-connection facility were set up on the ground space between the building and the parking lot. Cables between the rooftop and the ground were housed in racks built in the space between the outer walls and emergency stairs (Fig. 8).
Small-capacity PV inverters are set up at separate spots in some mega-solar system designs. But Gould said, "Taking into consideration wiring and running costs after the operation begins, we reached the conclusion that using large-capacity PV inverters would result in lower costs.".
Power generation has been favorable in the approximately six months since the plant began operation, outperforming the estimate by more than 10%.
