Industrial parks are under increasing pressure to reduce electricity costs, improve energy reliability and meet long-term carbon reduction goals. For many manufacturing parks, electricity is no longer just an operating expense. It has become a key factor affecting production stability, tenant satisfaction and future competitiveness.

The HMZ Qianhong Industrial Park PV + Energy Storage Project shows how rooftop solar, commercial and industrial energy storage, and smart energy management can work together in a real industrial park scenario.

By combining approximately 4.36MW of rooftop PV capacity, a 3.65MWh energy storage configuration and HMZ smart EMS monitoring, the project helps transform unused factory roofs into clean energy assets while improving the park’s overall energy flexibility.

Project Overview

Qianhong Industrial Park is a manufacturing-oriented industrial park with multiple factory buildings, large rooftop resources and concentrated daytime electricity demand. The park serves more than 30 resident enterprises, covering production, warehousing, office and supporting facilities.

For this type of commercial and industrial energy scenario, power demand is not only high but also dynamic. Production equipment, lighting, air conditioning, office systems, elevators and auxiliary facilities all create continuous electricity consumption during working hours.

At the same time, industrial park operators usually face several common challenges:

• Rising electricity costs
• High daytime load demand
• Peak power pressure
• Need for cleaner electricity
• Limited visibility of real-time energy data
• Power reliability requirements from resident enterprises
• Long-term carbon reduction pressure

Based on these needs, HMZ designed an integrated PV + energy storage solution for the park.

Basic Project Information

This project is not only a rooftop solar installation. It is a complete industrial energy management project designed to coordinate power generation, storage, load consumption and grid interaction.

Why Industrial Parks Need PV + Energy Storage

Industrial parks are ideal for rooftop PV because their electricity demand is usually concentrated during the daytime, which matches solar generation hours. Large factory roofs can be used for distributed PV installation without occupying additional land.

However, rooftop PV alone cannot solve every energy problem.

Solar power generation changes with weather and time of day. Industrial load also changes according to production schedules. When solar generation and load demand do not match perfectly, part of the renewable energy value may not be fully used.

This is where energy storage becomes important.

C&I energy storage system can store surplus solar power, discharge during high-load periods and support a more flexible energy operation strategy. For industrial parks, the value of energy storage is not only backup power. It is a flexible energy asset that helps optimize daily power use.

For the Qianhong Industrial Park project, PV + energy storage supports several key goals:

• Improve rooftop PV self-consumption
• Reduce peak electricity demand
• Improve clean energy utilization
• Support electricity cost optimization
• Make energy data visible and manageable
• Improve power reliability for resident enterprises
• Build a foundation for future microgrid development

Rooftop PV: Turning Factory Roofs into Energy Assets

The project makes full use of available factory rooftops across the industrial park. The rooftop PV system generates clean electricity during the day and supplies power close to the actual load.

This is especially valuable for industrial parks because electricity is generated near where it is consumed. Compared with remote power generation, rooftop PV can reduce transmission distance and improve local clean energy utilization.

The Phase I rooftop PV system has an installed capacity of 1.98MWp. According to project data, it is expected to generate approximately 1.9839 million kWh of clean electricity in the first year. Over a 25-year operation period, the Phase I system is expected to generate approximately 46.2567 million kWh of clean electricity.

For park owners, this means the rooftop is no longer only a building structure. It becomes a long-term energy asset.

C&I Energy Storage: Making Solar Power More Flexible

The project includes a 3.65MWh energy storage configuration to improve the flexibility of the entire energy system.

During the daytime, rooftop PV gives priority to supplying electricity to the park’s internal loads. When PV generation is higher than real-time demand, the energy storage system can store surplus clean power.

During high-load periods or peak electricity price periods, the ESS can discharge to reduce grid power demand. This helps the industrial park smooth its load curve and improve the economic value of rooftop PV.

The energy storage system supports:

• PV surplus energy storage
• Peak shaving
• Load curve optimization
• Backup support for selected critical loads
• Grid pressure reduction
• Higher renewable energy utilization
• Future microgrid expansion

For C&I users, energy storage is not simply a battery cabinet. It is a controllable energy asset that can participate in daily energy optimization.

Smart EMS: Making Energy Data Visible and Controllable

One of the most important values of this project is smart energy management.

The HMZ smart EMS platform monitors PV generation, site load, storage power, battery SOC, daily generation, device status and system operation trends. Instead of relying only on monthly electricity bills, the park operator can understand energy behavior in real time.

For an industrial park with more than 30 resident enterprises, this visibility is especially important. Different factories may have different load profiles, working hours and power requirements. A smart EMS allows the park to manage energy at the platform level rather than treating each building separately.

The EMS helps monitor:

• Real-time PV output
• Site load demand
• Storage charging and discharging status
• Battery SOC
• Daily PV generation
• Energy distribution
• Device operation status
• System health
• Environmental and carbon reduction data

With clear energy data, the project becomes easier to operate, easier to maintain and easier to optimize.

Environmental and Economic Value

The Qianhong Industrial Park project brings both energy and environmental value.

The Phase I PV system is expected to save approximately 674.38 tons of standard coal and reduce approximately 1,847.98 tons of CO₂ emissions. These figures are important because industrial energy transition is not only about installing solar panels. It is about helping factories and industrial parks build a cleaner and more sustainable operating model.

For manufacturing companies, clean electricity can also support ESG communication, low-carbon production claims and long-term brand competitiveness.

This is especially relevant for export-oriented manufacturers. As global buyers pay more attention to carbon footprint and sustainable supply chains, industrial parks with cleaner energy infrastructure can become more attractive to tenants and partners.

Key Benefits for Industrial Park Owners

1. Lower Energy Cost Pressure

The combination of rooftop PV and energy storage helps reduce grid electricity consumption and improve the use of self-generated clean power. Energy storage also makes it possible to shift part of the electricity use from high-cost periods to lower-cost periods.

2. Better PV Self-consumption

Without energy storage, solar power must be consumed immediately or exported. With ESS, part of the surplus PV generation can be stored and used later, improving the overall value of the PV system.

3. Peak Shaving and Load Optimization

Industrial parks often have load peaks caused by production equipment, HVAC systems, compressors, elevators and lighting. ESS can discharge during high-load periods to reduce peak demand and smooth the load curve.

4. Improved Power Reliability

Power interruptions can affect production lines, IT equipment, safety systems and other critical loads. A properly configured energy storage system can provide backup support for selected loads and improve energy resilience.

5. Measurable Carbon Reduction

The Phase I system is expected to reduce approximately 1,847.98 tons of CO₂ emissions and save approximately 674.38 tons of standard coal. These values help the park communicate its clean energy contribution more clearly.

6. Better Service for Resident Enterprises

With more than 30 resident enterprises in the park, energy stability and cost control directly affect tenant experience. A PV + ESS system helps the park provide a cleaner, more transparent and more reliable energy environment.

7. Stronger Foundation for Future Microgrid Development

With PV, ESS, EMS and load management already integrated, the park can further expand the system to support EV charging, diesel generator coordination, demand response or multi-energy management.

Why This Case Matters for Overseas C&I Projects

Many industrial parks around the world face similar energy challenges. In regions with high electricity prices, unstable grids or diesel generator dependence, PV + energy storage can create strong value.

This type of solution is especially suitable for:
