Solar street lights in Ningxia 2010

 Time: June, 2010

Location: Ningxia, China

Major Challenge: Ningxia is very cold in winter. The lowest temperature can reach -27℃. So we require the solar street light to be of low temperature resistance. Due to the dry climate and heavy dust in Ningxia, solar street lights are required to feature outstanding dust resistance.

SUNLAIRE Solution: 1. Gel battery is better resistance to extreme weather conditions, so we chose gel battery as the power source of the solar street lights. 2. The battery has to be buried underground to maintain a relatively high and stable operating temperature. 3. Attention: we must bury the battery 0.5 to 1 meter below the frost line. 4. We selected the cobra head LED lamp because of its fully sealed aluminum shell which kept the sand and dust out of the interior.
