2. Project Background

Climate and Infrastructure Challenges in Shijiazhuang

Shijiazhuang is located in a temperate monsoon climate zone, featuring concentrated rainfall and extensive flatland water-engineering systems. Monitoring points spread along riverbanks and irrigation channels often lack stable grid access, facing outages during heavy storms, floods, and seasonal impacts like strong winds or temperature shifts.

Limitations of Traditional Power Methods

Conventional power infrastructure struggles in these environments. Grid instability, moisture-caused corrosion, and wind-related equipment wear shorten device lifespan and increase failure rates. Maintenance requires traveling across distributed canal and riverbank areas, raising costs and delaying emergency responses.

3. Solar Power System Design for Shijiazhuang

High-Efficiency 720W Photovoltaic Array

The system uses a 720W multi-panel configuration with wind-resistant and anti-corrosion coatings. Daily solar generation is sufficient for high-load water-management equipment such as HD cameras, telemetry devices, and environmental sensors.

800Ah High-Capacity Storage for Multi-Day Continuit

The 800Ah battery bank offers deep-cycle stability and high/low-temperature resilience. It ensures uninterrupted monitoring during continuous cloudy or rainy periods—common across Hebei’s water-management zones.

Intelligent Energy Coordination and Environmental Protection

A smart controller monitors PV output, battery status, and device load in real time. Reinforced PV brackets resist strong winds, while waterproof and dustproof battery enclosures provide reliable operation in harsh outdoor environments.
