Solar street light advantage
The main advantages of solar lights include: ① energy efficiency, solar street lighting is a natural use of natural light, reducing energy consumption; ② security, street lighting mains may exist due to the construction quality, materials aging, power supply disorders, and many other causes Security risks. The solar lamps do not use alternating current, the battery is used to absorb solar energy, the low-voltage direct current into light, there is no security risk; ③ environmental protection, solar lights pollution, no radiation, in line with modern environmental protection concepts; ④ high-tech, solar energy street light intelligent controller to control, you can automatically adjust the brightness of the lamp according to the natural sky brightness within 1d and people at the brightness under various environmental needs; ⑤ durable, the vast majority of the solar cell module production technology, are sufficient to guarantee 10 In the above performance does not drop, the solar cell module can generate electricity for 25 years or longer; ⑥ low maintenance costs, in remote areas far away from the town, in order to maintain or repair conventional power generation, transmission, lights and other equipment of the high cost. Solar lights only require periodic inspection and little maintenance work, the maintenance costs less than conventional power generation systems; ⑦ mounting assembly building blocks, flexible installation, user according to their needs and adjust the size of the capacity of solar street lights ; ⑧ autonomous power supply from the network operation of solar-powered street lights have autonomy, flexibility. Insufficient solar lights
High cost, solar street early investment, the total cost of a solar street light is the same as 3.4 times the power of conventional lights; low energy conversion efficiency, the conversion efficiency of solar photovoltaic cells is about 15% to 19%, in theory, silicon solar cell conversion efficiency up to 25%, but in the actual installation, depending on the surrounding buildings block may cause reduced efficiency. Currently, the solar cell area of ??110W / m2,1kW the solar cell area of ??approximately 9m2, such a large area is fixed to the pole is almost impossible, so for fast road, the main road is still not applicable; that is geographical and climatic conditions affect large because relying on the sun to provide energy, local geography and climate weather conditions directly affect the use of lights. Rainy days is too long it will affect the lighting, resulting in illumination or brightness of less than the national standards, not even light, during the day due to insufficient solar street lighting Chengdu Huanglongxi region, resulting in too little time in the evening light; Yuan life and low cost devices. Higher prices batteries and controllers, and the battery is not durable enough, must be replaced periodically, the service life of the controller is generally only 3 years; low reliability. Due to climatic and other external factors too, resulting in reduced reliability. Shenzhen Binhai Avenue solar street with 80 percent of the sunlight can not rely alone, and Welcome Road Dazu County, the same as are used in the mains dual power supply mode; management and maintenance difficulties.
