FAQ

Very large roofs can house industrial scale PV systems in the range of 1–10 MW. Our 3500KW system covering 28,000㎡ across 15 buildings represents a large-scale industrial installation that achieves economies of scale impossible with smaller systems. The 233KW average per building enables significant cost reductions through bulk purchasing, standardized installation processes, and centralized monitoring systems, while generating 4.2 million kWh annually—equivalent to powering thousands of homes.

Rooftop solar PV systems work particularly well for commercial and industrial facilities since they usually have large, flat roofs unobstructed by shading and their operations consume a lot of energy. The 75% self-consumption ratio maximizes economic benefits because industrial electricity rates are typically higher than grid feed-in tariffs. This high self-use percentage directly offsets expensive industrial electricity consumption, contributing to the annual savings of $175,000 for enterprises and supporting the 5.2-year payback period.

Our customers generally see a payback period of 3 – 5 years. Considering a solar PV system has a lifespan of 25+ years, once the system is paid off, the organization benefits from no-cost solar energy generated by their system for the remainder of its lifespan. The 5.2-year payback period is competitive with industry standards, particularly for such a large-scale installation. With 25-year cumulative benefits of $11.6 million and annual comprehensive benefits of $465,000, the system provides nearly 20 years of profit after payback completion.

Adequately installed panels do not cause any destruction to your roof. The system is designed to withstand Category 12 typhoons with aluminum alloy mounting systems that provide strong corrosion resistance and long service life. The distributed load across 15 buildings averages 233KW per building, ensuring no single structure bears excessive weight. The design includes comprehensive lightning protection and grounding systems, ensuring safe operation across the entire 28,000㎡ installation area.

The hybrid model optimizes revenue by consuming 75% of generated power on-site at avoided industrial electricity rates, while selling 25% surplus to the grid. This generates annual power generation revenue of $290,000 plus electricity cost savings of $175,000 for enterprises. The model benefits from both avoiding high industrial electricity costs and earning feed-in tariff revenue, creating multiple income streams that accelerate the 5.2-year payback period.

The advanced monitoring system with remote monitoring and fault early warning capabilities significantly reduces maintenance requirements across the 15-building installation. Smart O&M (Operations & Maintenance) enables centralized monitoring of all 3500KW capacity, with intelligent fault detection and predictive maintenance scheduling. Regular maintenance includes quarterly visual inspections, annual electrical testing, and routine panel cleaning to maintain the ≥21.5% module efficiency and ≥85% system efficiency.

The project became a benchmark industrial & commercial distributed solar project in southern Anhui, driving 15+ enterprises in Xuancheng industrial parks to initiate solar projects. With annual CO₂ emission reduction of 2,100 tons (equivalent to planting 8,400 trees), the project demonstrates how large-scale solar installations can support industrial park green and low-carbon transformation while benefiting from Anhui Province distributed solar subsidies. This provides reference cases for industrial enterprise green transformation throughout the Yangtze River Delta region.

Coordinating installations across 15 buildings requires sophisticated project management including synchronized electrical connections, standardized mounting systems, and integrated monitoring solutions. Each building’s unique operational schedule and electrical load patterns must be considered for optimal system design. The intelligent monitoring platform enables centralized oversight while maintaining individual building performance optimization, ensuring consistent generation across all facilities while accommodating varying industrial operational requirements and maintenance schedules.
