*System Design:
· Maximum PV Modules per String: 21
· Maximum String Open Circuit Voltage: 49.9 * 21 = 1047.9V (within 1100Vdc max limit)
· Maximum String Operating Voltage: 41.96 * 21 = 881.16V (within 200-1000Vdc operating range)
· Solar Array Current: 13.11 * 2 = 26.22A (within the 40A max withstand current per MPPT)
· Average Daily Power Generation: 600kWh * 9 = 5,400 kWh
This installation operates under the Net Accounting category, feeding excess generation back into the national grid. If PV generation is insufficient and consumption exceeds generation, the national grid supplies power to the factory. At the end of the month, if the PV generation exceeds consumption, the grid supplier compensates for the excess units. Otherwise, the factory pays for the additional power used. This power transition occurs through the common coupling point.
The client’s primary goal is to significantly reduce electricity costs, and this project does not include a battery backup system.
This project stands as a testament to the potential of renewable energy in driving cost savings and environmental impact.
