of the LED lamp and the two

(1) of the LED lamp and the two systems are substantially the same pole costs, the main   LED Downlight  difference is the solar panels. Typically solar panels power is about three times the power LED lamps. If the LED is 100 watts, then requires the use of solar panels 300 Watt. Currently the price of solar panels has been reduced to 23 yuan / watt, 300 watt is 6900 yuan. In addition, the solar system also needs batteries, but its cost is equivalent to the switching power supply AC power costs. So the two can be offset. So light itself cost difference is mainly solar panels.

LED Strip

(2) AC-powered LED lights during the initial installation of the biggest expenses is the cable laying. Most people think that is mainly the cost of the cable itself, but in addition to the cable itself, its laying, ancillary facilities (manholes, power distribution equipment) and so on, a lot more expensive than the cable itself. Now assume that 10 kilometers of roads, for example, every 30   GU10 meters an opposite place, needs a total of 666 LED lights, solar lights if used, then the cost can be recovered within five years can also save 430,000 yuan, five years later annual electricity can save 1.22 million yuan.
