Warehouse logistics solar photovoltaic energy storage integrated solution is a combination of solar photovoltaic power generation and energy storage system, applied to the warehousing and logistics industry energy management program. The solution aims to improve the energy utilization efficiency of warehousing and logistics enterprises, reduce operating costs and realize green and sustainable development. This program is based on 2025 industry standards and engineering practice related experience, the relevant data in the program is also based on the current industry equipment data, the specific program is as follows:

I. Program Objectives

1. Enhance the self-sufficiency rate of electricity consumption

For warehousing logistics, generally through the roof photovoltaic system to meet the daily electricity needs of the warehouse 60% -80%, combined with the energy storage system can also be realized at night power supplement.

2. Reduce carbon emissions

Take 10,000 square meters warehouse as an example, it can reduce carbon dioxide emissions by 300-500 tons per year, which basically meets the requirements of new energy saving and carbon emissions in Europe and the United States.

3. Optimize cost expenditure

Generally in the whole life cycle of warehouse operation, take 25 years as an example, it can reduce the cost of electricity and energy by 40%-60%, and the payback period can be controlled in 6-8 years.

4. Realize grid synergy

Solar photovoltaic power can be realized grid-connected operation, the excess power can be centered on the Internet to obtain additional profits, and enhance the efficiency of energy use.

Ⅱ.System architecture and implementation process

1. Resource assessment and design phase
Before installing photovoltaic equipment, satellite mapping is used to assess the effective installation area of the roof, the inclination angle and the shading situation to ensure that the effective utilization rate of photovoltaic modules exceeds 21%.

According to the actual situation of warehousing, the photovoltaic energy storage ratio calculation, according to the average daily electricity consumption of the warehouse matching lithium iron phosphate battery energy storage system, according to the calculation of 50-100kW-h/k ㎡, then the capacity of the energy storage according to the daily electricity consumption of 30% -50% configuration.

According to the demand can increase the intelligent integration design, the deployment of Internet of Things monitoring platform to achieve real-time optimization of photovoltaic power generation, energy storage charging and discharging, load scheduling, here you can refer to the iBuilding intelligent BIPV technology.

2. Engineering construction phase

Projects	Technical Points	Implementation Cycle
Photovoltaic Installation	Adopting lightweight double-glass module, general weight less than 18kg/㎡, suitable for logistics warehouse color steel tile roof load-bearing standards, single-day construction area should be more than 500㎡.	15-30 days
‌Energy Storage Deployment	Modularized containerized energy storage unit (500kW/1MWh), supporting plug-and-play and hot-swap maintenance.	5-7 days
‌Grid-connected systems	Equipped with bi-directional inverter and anti-reverse current device, meets China's GB/T 19964-2022 grid connection standard, and synchronizes with the completion of grid access approval.	10-20 days

3. Commissioning and Operation and Maintenance

After installation, energy efficiency verification is required, requiring 72 hours of continuous power generation testing to verify that the deviation of the system power generation forecast is less than 5%.

After adopting intelligent O&M, drone inspection + AI fault diagnosis can be used to reduce O&M cost by 30%, and MTTR (mean time to repair) is less than 2 hours.

Ⅲ. Cost and Benefit Analysis

1. Investment cost (take 10,000 square meters warehouse as an example)

Projects	Unit price	Total cost	Remarks
Photovoltaic Systems	0.4$/W	Half a million dollars	Installed capacity 1MW
Energy Storage Systems	0.2$/Wh	US$170,000	1MWh configuration
Grid Connection and Intelligent	70,000 dollars	$70,000	Including monitoring platform and grid interface
‌Total	-	‌$0.7 million	Including installation fee, excluding land cost

2. Economic returns

According to the industrial electricity price of $0.1/kWh and 70% self-use ratio, the annual average annual savings of about $100,000 per year, effectively achieving the purpose of saving electricity costs.

Excess electricity can also be integrated into the public grid, enjoying a subsidy of $0.05/kWh, with an annual income of about $20,000 USD.

3. Payback period

Based on the total cost of $700,000 total investment and annual revenue of $100,000 static payback period, it is about 6.5 years.

IV. Risk Control Measures

1. Technology risk

Priority is given to the use of TÜV-certified modules and UL-certified energy storage equipment, and the warranty period of the relevant solar photovoltaic equipment is more than 12 years, as well as supporting power generation insurance.

2. Policy Risk

Sign a long-term power purchase agreement (PPA) with the local government to lock in the validity of the subsidy policy.

3. Operation Risk

Under the environment of local power tension, backup diesel generators can be established. Diesel power generation only accounts for 2% of the total investment, which can effectively guarantee the power supply of key loads such as cold chain in extreme weather.

V. Grid connection and energy management

1. Grid connection mode

Under normal circumstances, it can adopt the mode of “self-generation and self-consumption + surplus power on-line”, and configure smart meters to realize two-way metering.

2. Virtual Power Plant (VPP)

Access to the regional energy management platform, participate in demand response, you can get additional peak revenue.

Ⅵ.Typical Cases

Transfar Logistics Port Project in Zhengzhou, China:

The roof area of the warehousing and logistics port is 25,000 square meters, with an installed capacity of 2.5MW and supporting 1.2MWh of energy storage.

Annual power generation of 2.85 million kWh, 82% self-consumption rate, carbon emission reduction of 620 tons/year, payback period of 6.2 years.

VII. Conclusion

This warehousing and logistics solar photovoltaic energy storage program is designed through the “photovoltaic + energy storage + intelligent scheduling” trinity, to realize the green and low-carbon transformation of warehousing and logistics, both economic and reliable, in line with the national “dual-carbon” strategy and the logistics industry to reduce costs and increase efficiency needs. The actual project needs to be combined with the local light conditions. The actual project needs to be combined with local lighting conditions, electricity price policy and warehouse structure for customized optimization.
