The BIPV systems generate about 150,000 kWh power per year, for this office building with a building area of 23,546 m², accounting for 12.7 % of the total energy consumption of the building. The annual generating capacity of the PV roof shading, the PV curtain wall, the PV carport and the PV louver parapet respectively is 77,287 kWh, 56,003 kWh, 14,501 kWh and 2,520 kWh power, contributing to 51%, 37%, 10% and 2% of the total generating capacity of the PV systems. Furthermore, the average daily thermal yield from two other PVT systems is about 10,832 kJ and 13,253kJ, which can provide about 60,000 litres of hot water for the building each year.

In this project, the microgrid uses two sets of energy storage inverters to run in parallel to form an AC dual-ended hybrid micro-grid redundant system. The energy management system can effectively regulate and control power resources by energy storage, and can well balance the difference in electricity consumption between day and night as well as different seasons by adjustment to ensure grid security, realizing the traditional UPS function to protect the load side power.
