Comprehensive Solutions for Solar Photovoltaic Systems in Industrial Parks

Shandong Jining Huaqin Industrial Park 1.2 million square meters of photovoltaic projects

The comprehensive solution of solar PV system for industrial parks builds distributed PV power generation network by installing PV power generation equipment on the roofs of buildings, open spaces and other areas in the parks, aiming to provide clean energy supply for enterprises in the parks, reduce the cost of energy consumption, improve the efficiency of energy utilization, and at the same time combine with the technologies of energy storage and intelligent microgrid to realize the optimal management of energy, and to promote the development of industrial parks in the direction of green, low carbon, smart and high efficiency development.

I. Program Objectives

1. to replace part of the traditional electric energy through the construction of photovoltaic energy, to replace 30%-50% of the traditional grid electricity through distributed photovoltaic power generation system, and to reduce the comprehensive energy consumption cost of the park by 20%-30%. 2. to move towards the green and low-carbon energy utilization in the industrial park, and to improve the energy utilization efficiency.

2. Transition to green energy in the industrial park to achieve annual emission reduction of more than 4000 tons of CO₂, to meet the requirements of ESG certification, and to enhance the competitiveness of the park's investment promotion.

3. Enhance the economic resilience of various energy sources, combine with the energy storage system to realize peak and valley arbitrage, and ensure the stable power supply of key production lines during the fluctuation of the power grid.

Ⅱ.Technical Path and System Composition

Example of operating effect of photovoltaic facilities in industrial parks

1. PV core equipment selection

Regarding the procurement of photovoltaic modules, the efficiency of monocrystalline silicon modules needs to exceed 20%, and for roof or carport scenes, lightweight products can be selected, in which the load does not exceed 15kg/㎡.

In terms of the energy storage system, it is necessary to configure more than 2 hours of storage capacity equipment, accounting for 15%-20% of the installed capacity of PV, which can better support the virtual power plant mode to participate in grid peaking.

2. Grid-connected mode selection

Model	Applicable Scenarios	Economic Advantages
Self-generation and self-consumption of surplus electricity	Large-scale factories with stable daytime electricity load	Self-utilization rate of more than 70%, when the IRR is increased to 12%
Full Internet access	Expansion areas with abundant land resources	Enjoy lower benchmark tariffs

Ⅲ.Implementation Process

1. Preliminary site and power consumption assessment (1-2 months)

The effect of installing solar panels on the park's housing projects

In the pre-engineering stage, it is necessary to map the available area of the roof or parking lot and use drone modeling to assess the shadow shading of the park. And analyze the electricity consumption curve of the last three years to determine the proportion of energy storage allocation, such as the electronics factory recommended 25% of electricity allocation, etc.

2. Energy storage system design (2-3 months)

The energy storage system for PV can adopt string inverter plus intelligent monitoring architecture, with one 250kW inverter for every 500kW PV. For carport PV adopt tilt angle 10° double-glass modules, which can improve wind pressure resistance and self-cleaning ability.

3. Construction and installation (3-6 months)

Key Processes	Technical points	Quality Assurance Measures
Roof reinforcement	Color steel tile roof live load upgraded to 7kN/m2	Third party structural safety inspection
Electrical Grid Connection	Configuration of anti-islanding protection device	Real-time monitoring of power quality

Ⅳ.Commissioning and operation and maintenance

1. The whole energy storage system intermodulation

The whole PV energy storage system will be tested for 72 hours of full-load operation to verify that the charging and discharging efficiency of the energy storage system is above 92%. At the same time, it is connected to the distributed PV intelligent cloud platform to realize the panoramic monitoring of 40MWp power station. 2.

2. Adopt intelligent operation and maintenance system

Use intelligent operation and maintenance system for predictive maintenance, let AI algorithm analyze the module decay rate, to reach an annual average of less than 0.5% as qualified data. Regular cleaning optimization, using drone inspection to generate dust distribution heat map, guiding the drone to carry out accurate cleaning.

V. Cost-benefit analysis (taking 1000kW PV project as an example)

Project	Amount/indicator (RMB)
Total Investment	9 million yuan (6 million for modules + 3 million for construction)
Annual Electricity Generation	11.46 million kWh (4 hours of sunshine/day)
Annual Revenue Composition	Electricity cost saving: 1.2 million RMB
	Green electricity subsidy: 180,000 Yuan (0.12 Yuan/kWh)
	Carbon trading revenue: 60,000 yuan (100yuan/ton)
Payback Period	5.8 years (IRR 10.2%)

VI. Implementation Recommendations

1. Policy convergence

For areas with policy subsidies, priority can be given to declaring provincial green park demonstration projects to obtain construction subsidies for PV projects.

2. Mode Innovation

New load synergy scenarios such as PV plus cold chain logistics and data centers can be explored in the park.
