1.Height:4M,6M,7M,8M,9M,10M,12M lights for the night.2.Solar Panel Module: With 2-3*80W Nanowin HighEfficiency Thin Film Solar Module. The light absorption is excellent, even undercloudy day, it can provide enough power for thebattery tostore.(warranty: 25 years)3.Battery: With Lead Acid battery. The life spanof lead acid battery is about 2 years. (Warranty: 1year).If with Nanowinlithium-phosphate battery (LiFePO4), the life span ofbattery can be up to more than 10 years. (warranty: 6 years)4.The high efficient Sun Tree Street Lightutilizes a two-stage constant current circuit (Patent No.: 200720033740.0) ,It can control luminance ofhigh illuminance before (12 a.m.) and the low illuminance after midnight (0-6a.m.).5.The battery is installed under the ground(Patented in China),itensuring the battery to work under the same temperature as toexpand life span of battery.6.Bulbs:Low energy consumption and highbrightness LED bulb*87.As the battery is fully charged, it is expectedto last for about 8 days even under cloudyconditions.8.NanoWin’s CIGS battery only requires two-hoursof direct sunlight and can fully supply enough power for thestreet lights for thenight.9.Thelife span of LED is 10 to 20 years (warranty is 6years).10.Resisting wind power: 120KM/H (resist 12 degree wind), and it canincrease to 250KM/H for special need.
