If we design, "city road lighting design standards" in the ¡éñ, ¡é¨° type of road lamps, since the electricity in daily 3-4.8KWH, solar power needs to reach more than 1KW. Let us not consider the cost of 1KW solar cells, only on solar cell design work area will make it difficult to carry out. Currently, the solar cell area of ??120W / square meter, the solar cell area of ??about nine square meters 1KW, such a large area is almost impossible in the like rod fixed. Further, in order to meet the city in terms of continuous rainy days to work, but also to expand the capacity of the battery several times, it also requires a lot of battery box. See our website
