In many remote areas, mining sites, rural regions, and temporary gas supply locations, access to stable grid electricity is limited or unavailable.
However, the demand for liquefied petroleum gas (LPG) continues to increase due to its efficiency and clean-burning characteristics.
To ensure reliable operation of LPG skid-mounted stations under off-grid conditions, integrating a solar power supply system has become a practical, safe, and cost-effective solution.
The 20m³ LPG skid-mounted station mainly consists of the following equipment:
1x 20m³ LPG storage tank
2x LPG pumps with electric motors
2x electronic filling scales
LPG filling valves
Process pipelines and safety accessories
The entire system adopts a skid-mounted design, offering high integration, easy transportation, fast installation, and rapid commissioning.
For sites without grid electricity, the LPG skid-mounted station is equipped with an independent solar power supply system, capable of meeting the electrical requirements of the main operating equipment.
The solar power supply system includes the following key components:
Photovoltaic (PV) panels
Solar charge controller (MPPT or PWM)
Inverter (DC to AC conversion)
Battery storage system
Power distribution and protection devices
The system stores solar energy generated during daylight hours and supplies power continuously to ensure stable station operation.
The solar power system is mainly used to supply electricity for:
LPG pump motors
Electronic filling scales
Control and instrumentation systems
Electric valves and safety control devices
Working principle:
During daytime, solar panels convert sunlight into DC electricity. The generated power is regulated by the controller to charge the batteries and supply loads.
When solar energy is insufficient or during nighttime operation, the battery system provides power to the inverter, which delivers stable AC electricity to ensure continuous operation of the LPG station.
The solar-powered 20m³ LPG skid-mounted station offers several key advantages:
No dependence on grid electricity, ideal for off-grid locations
Reduced infrastructure investment and operating costs
Independent and reliable power supply
Skid-mounted design for flexible deployment
Clean and environmentally friendly energy solution
This solution is especially suitable for applications in Africa, Southeast Asia, mining areas, rural communities, and temporary LPG supply stations.
Safety is a critical consideration in the integration of solar power systems with LPG installations:
Proper separation of electrical systems and LPG process equipment
Use of industrial-grade or explosion-proof electrical components where required
Comprehensive electrical protection and emergency shutdown systems
Battery systems with overcharge, over-discharge, and short-circuit protection
With proper engineering design, the system ensures safe and reliable operation under various working conditions.
With the global promotion of clean energy and LPG infrastructure, solar-powered LPG skid-mounted stations offer broad application potential in off-grid and energy-deficient regions.
This solution provides a low-cost, sustainable, and rapidly deployable option for LPG storage and filling projects.
By integrating a solar power supply system, the 20m³ LPG skid-mounted station can operate reliably without access to grid electricity.
Through proper configuration of photovoltaic panels, battery storage, and inverter systems, solar-powered LPG skid stations provide stable electrical support for LPG storage and filling operations, making them a proven and feasible solution for remote and off-grid applications.
This is the first one.
