In the rugged terrain of Tibet’s Shannan region, solar heating systems are proving to be one of the most effective and sustainable ways to deliver reliable warmth—even in challenging industrial settings. One standout example is the recent project at Duijue Lead Mine, where a large-scale flat plate solar collector system was deployed to meet the heating needs of a 600 square meter area.
Project Overview
Location: Duijue Lead Mine, Shannan City, Tibet
Installation Area: 600 m²
Collector Type: Flat Plate Solar Collector
Application: Space heating for working and residential areas
Backup: Electric heating element (integrated)
Flat plate solar collectors are particularly well-suited for high-altitude, high-radiation environments like Tibet. Their robust design, ease of installation, and low maintenance requirements make them ideal for industrial use in remote locations.
In this project, the collectors were mounted at optimal tilt angles to maximize absorption of solar radiation throughout the winter months. The solar heating system is used to maintain indoor temperatures in operational and staff buildings, ensuring comfort and safety even during harsh weather conditions.
The solar-powered heating system has significantly reduced dependence on diesel or coal, which are expensive and logistically challenging to transport in this region. On average, the system supplies over 70% of daily heating needs purely through solar energy.
It’s a textbook case of how a solar heating system can not only reduce operating costs but also align industrial operations with low-carbon development goals.
Duijue’s remote location presented multiple challenges: difficult access, limited grid power, and extreme cold. However, the modularity of the flat plate solar collector design enabled on-site assembly without heavy equipment. The project also incorporated smart controls and insulated piping to minimize thermal loss.
✅ CO₂ emissions reduction by ~25 tons/year
✅ Lower heating costs by 50–70% seasonally
✅ Reduced reliance on trucked-in fuels
✅ Low O&M costs over 10+ years of operation
As governments and enterprises seek cleaner energy pathways, this project demonstrates the scalability of industrial solar heating. Mines, factories, and remote installations across Western China and Central Asia can benefit from similar solar heating systems using flat plate solar collectors.
