70-kW-Solar-PV-Dachanlage in einem chinesischen Fabrikwohnheim | Saubere Energie & netzgekoppelte Rentabilität

With rising energy costs, businesses seek not only to cut electricity bills but also to generate additional income via grid-tied solar systems. Located in Zhongshan, Guangdong, this 70 kW rooftop on-grid PV system powers a factory dormitory, meeting communal demand while exporting surplus electricity to the grid for reliable long-term returns.

Project Type: On-Grid Solar
Standort: China
PV Installed Capacity: 70 kW
Inverter Capacity: 65 kW

Tailored Solution

To maximize rooftop potential, the system integrates ~128 ST-M-550W high-efficiency modules with 25 kW + 40 kW Huawei inverters, enabling smart grid-tied operation. With an annual output of ~78,000 kWh, the system meets most dormitory electricity demand without battery storage, significantly reducing energy costs.

ST-M-550W Module Benefits

• 22% conversion efficiency for optimized rooftop yield
• IP68 waterproof rating for durability in diverse climates
• MBB half-cell technology for higher output and shading tolerance
• Excellent anti-PID performance for long-term stability
• Fast installation with up to 12 years warranty for secure ROI

Toward a Zero-Carbon Future

After commissioning, the project not only reduced dormitory electricity bills but also generated revenue through grid exports. Annual CO₂ emissions are expected to fall by tens of tons, supporting corporate ESG and carbon neutrality goals. The grid-tied arbitrage model transforms green investment into measurable financial returns.

From self-consumption to grid-tied arbitrage, solar power delivers dual value to businesses. GODE Commercial & Utility PV Solutions enable enterprises to optimize costs and grow revenue with clean energy.
