Solar Power Supply for Container Houses

Container houses can be equipped with solar power supply systems, particularly suitable for off-grid or areas with inconvenient power supply, achieving self-sufficiency in electricity through rooftop photovoltaic panels or independent energy storage containers.

Integration Methods and Structural Adaptation

1. Rooftop Photovoltaic Panel Installation:
   The roofs of container houses typically use steel frame structures capable of supporting photovoltaic modules. For example, the mobile houses manufactured by Guangzhou Zhengkai Fangcang have a roof thickness of 50mm, supporting the installation of 630W monocrystalline silicon panels. Such designs must ensure that the roof's load-bearing capacity matches the weight of the photovoltaic panels to avoid structural deformation.
2. Independent Energy Storage Containers:
   The photovoltaic power generation containers provided by Tianfunengke (Qingdao) New Energy Technology Co., Ltd. can be placed alongside residential containers and connected via cables for power supply. Their sealed structures can withstand harsh outdoor environments (such as dust and rain), making them suitable for scenarios without a stable power grid, such as remote construction sites or temporary camps.

Technical Parameters and Capacity Selection

1. Power Generation and Energy Storage Capacity:
   • Rooftop Integrated System: A single system can generate up to 50kW of power with an energy storage capacity of 200kWh gel batteries, suitable for small to medium-scale power needs.
   • Independent Energy Storage System: Taking Hebei Huaniu Electric Energy Technology's products as an example, the power generation capacity reaches 100kW with an energy storage capacity of 200kWh lithium iron phosphate batteries, offering a cycle life of up to 15 years, suitable for high-load or long-term off-grid scenarios.
2. Capacity Assessment Method:
   Select the system capacity based on power needs. For example, a 20㎡ container house requiring daily lighting and air conditioning should be equipped with a 3-5kW system, with a 20% reserve to accommodate sudden demands or equipment aging.

Purchase and Installation Considerations

1. Environmental Adaptability:
   • Lightning Protection Requirements: Areas with high altitudes or frequent thunderstorms require the installation of lightning rods to prevent damage to the photovoltaic system from lightning strikes.
   • Temperature Tolerance: In low-temperature environments, cold-resistant batteries (such as a 51.2V100AH system that can start at -20℃) should be selected to ensure system stability.
2. Transportation Restrictions:
   If the height of an independent energy storage container exceeds 4 meters, an oversized transport permit is required; otherwise, there may be a risk of transportation violations.

Industry Application Cases

1. Oil Field Projects: Handan Yingxu New Energy's 51.2V100AH system is applied in the Inner Mongolia oil field operation area, meeting power needs in low-temperature environments and supporting drilling equipment operation.
2. Emergency Medical Care: Zuyuan Electric Power's explosion-proof containers, combined with photovoltaic systems, provided 72 hours of uninterrupted power supply to temporary hospitals after the Wenchuan earthquake, ensuring the normal operation of medical equipment.

By reasonably selecting integration methods, assessing technical parameters, and considering environmental and transportation conditions, the solar power supply system for container houses can achieve efficient and reliable off-grid power supply.
