Off-Grid Solar Power for Road Security Monitoring

PROJECT BACKGROUND

The monitoring station is located along a mountain road in Qianxinan, Guizhou, China. It collects real-time video data to support traffic management and road safety. The site is far from the grid, with complex terrain and changing weather conditions, making a stable and independent power supply essential for continuous operation.

THE CHALLENGE

Limited grid access at remote roadside locations.
Harsh weather including heavy rain, high humidity and fog.
High maintenance costs due to scattered sites and difficult access.

THE SOLUTION

Pbjie Solar’s off-grid solar power system uses a 200W photovoltaic panel to capture sunlight and charge a 120Ah battery. The integrated power management unit coordinates charging, energy storage and power conversion to supply compatible surveillance equipment. A weather-resistant enclosure helps protect critical components against moisture, dust and outdoor exposure.

KEY BENEFITS

Reliable Off-Grid Power

Supports road security cameras without convenient grid access.

Lower Installation Costs

Reduces long-distance cabling and excavation.

Reduced Maintenance

Minimizes site visits and battery replacements.

Weather-Ready Design

Performs well in challenging outdoor environments.
