Solar Street Lights in Xinjiang 2010

Time: May, 2010

Location: Xinjiang, China

Major Challenge: Xinjiang is located in western China, near the desert. It experiences low temperatures in winter, high temperatures in summer, and a significant temperature difference between day and night. Extremely cold and hot climates, along with large temperature fluctuations, pose a great challenge to battery of the solar street lights.

SUNLAIRE Solution: 1. We chose the gel battery which is better resistance to extreme weather conditions. 2. Since the battery of solar street lights require a relatively high and stable operating temperature, we chose to install the battery underground. 3. Attention: the battery of the solar street lights must be buried 0.5 to 1 meter below the frost line.
