Case Study of Nanjing Oulu Electric Residential Wind-Solar Hybrid Power Generation System
Residential Wind-Solar Hybrid Power Generation System – 600VA
The project is a livelihood project in the Inner Mongolia region. The total household load is 600VA, including lighting, low-power TVs, computers, refrigerators, and other small appliances, with an average daily electricity consumption of less than 3 kWh.

System Configuration Analysis:
According to meteorological data from the Inner Mongolia region, the annual average wind speed is 6 m/s (indicating relatively stable wind resources) and the average daily sunlight duration is 6 hours. The wind-solar hybrid power generation part of this system is configured with a 1:1 ratio, with a 300W wind turbine and a 300W photovoltaic (PV) array. Based on the power curve of the 300W wind turbine and assuming 10 hours of operation per day, the 300W wind turbine can generate an average daily output of approximately 1.6 kWh at a wind speed of 6 m/s.

System Configuration Analysis:
Assuming 6 hours of adequate sunlight per day, the 300W photovoltaic (PV) array can generate an average daily output of approximately 1.5 kWh. The entire power generation system therefore produces an average daily output of 3.1 kWh.
Based on this, the system is equipped with either two 12V 150Ah batteries (total storage capacity 3.6 kWh) or two 12V 200Ah batteries (total storage capacity 4.8 kWh) to ensure system safety and stability and to extend the service life of the system.

Residential Wind-Solar Hybrid Power Generation System – 3000VA
The project is a livelihood project in the Inner Mongolia region. The total household load is 3000VA, including televisions, computers, refrigerators, freezers, water heaters, and other appliances under 2,400W, with an average daily electricity consumption of less than 14 kWh.

System Configuration Analysis:
Assuming 6 hours of adequate sunlight per day, the 1,500W photovoltaic (PV) array can generate an average daily output of approximately 8 kWh. The entire power generation system therefore produces an average daily output of 15 kWh.
Based on this, the system is equipped with eight 12V 200Ah batteries, providing a maximum storage capacity of 19.2 kWh to ensure system safety and stability and to extend the service life of the system.
