 
                    Solar Street Light: NK-SL-8W
The integrated solar street light, which can also be called the all in one solar street light, combines the  high efficient solar panel, Li-battery can be used for 8 years, high brightness  leds, intelligent controller, and anti-burglary installation support together.  The design of the all in one solar street light combines the most advanced  green energy---solar energy, semiconductor leds, and Li-battery, nowadays. It  uses several practical and good control technology, such as mini-controller and  human infrared induction, and unites the integrated design to satisfy the needs  of low consumption brightness, long using time and maintenance free, and the  performance of water-proofing and heat dissipation are also perfect.

Application:
               The All in one integrated solar street light can be installed in all streets, auxiliary roads, paths in residential  subdistricts, mine areas, non-electricity zones, parks, parking lots and  villages to provide light, and the solar panel can charge the battery to  satisfy the need of lighting.               
 
 
 
 
Notice for use:
               1. Please choose suitable product model according to the sunshine intensity and annual solar radiation of the installation site.
               2. The battery can be stored for one to two months after fully-charged. It should be checked after long transportation or storage, and the battery should be charge regularly or it would be damaged.
               3. We should keep away with the shadow of obstacles of house or wood when install the integrated light. For those obstacles will reduce the generating efficiency and cause low working efficiency of the integrated light.
                 4. The cleanliness of the solar panel will have influence on the generating efficiency of the solar panel. So the surface of it should be cleaned, and the normal detergent can be used regularly to clean the panel.
