Certificated SOLAR SYSTEM

Solar street lights are developing better and better, gradually replacing traditional street lights. Because it is energy-saving, environmental protection and easy to maintain, more and more urban roads and rural areas have begun to install solar street lights. Especially in rural areas, since various some facilities are relatively imperfect, solar street lights should be a better choice. Let me introduce the common problems and solutions of solar street lights.1. Cleaning of solar panels of solar street lampsThe solar panels of solar street lights cannot accumulate dust for a long time, because it is not conducive to the solar panels to absorb sunlight. If the solar panel is shaded, it will affect the conversion efficiency of the solar panel, but in general, the solar panel does not need to be cleaned frequently, because the dust on the solar panel will be washed away when it rains. If it doesn't rain for a long time, you should clean the solar panels occasionally. Now a solar street light with panel sweeper came into being .1. Is the solar panel of the solar street light fragile?Solar panel is very strong, generally composed of fairly strong tempered glass panel, regular manufacturers will test the solar panel through hail, so even if this solar panel encounters heavy rain or hail, it has a certain ability to resist.2. Orientation of solar panels of solar street lamps We all know that the solar panel of solar street lights absorb sunlight and then convert it into electrical energy and store it in the battery. At night, the battery discharges the lamp head, so that the solar street lights light up. The orientation of the solar panel determines how much sunlight it can absorb and how much electricity it can convert into.The solar panels of solar street lamps generally face south, so that the solar panels can absorb more and more uniform light radiation.If the direction is wrong, the absorbed sunlight will be less, and the lights may not be on last long or not lit at all. Generally, manufacturers will design the best tilt angle for solar panels according to the sunshine conditions in the area.1. The best location to install solar street lights Generally, solar street lights should be installed in the places without shadow or shelter, because it is not afraid of wind and sun, and it needs to absorb enough sunlight to convert it into electrical energy, which is good for the operation of solar street lights.     1. The problem that the lights of solar street lights are not brightWhat should I do if the solar street light is not on? This is undoubtedly the question that customers want to ask most.If this problem really occurs, you can refer to the following steps: 1) Firstly,consider whether there are continuous rainy days, because if it rains for several consecutive days, it is normal for the lights to be on for a short time or not at night, and you can judge until the night of the clear weather 2) If the light does not light up after a period of use, please remove the light from the light pole, disassemble the light to check whether there is water/false welding/short circuit inside, can ask professional people to deal with it.3) If the wire connection is normal, can check the battery voltage is normal or not , if not, the battery or the controller is faulty, and you can replace it after further investigation     

Solar street light is a street light that converts solar energy into electricity for lighting, and it can be installed efficiently, quickly and simply in sunny places. It is widely used in the new rural areas, urban and rural roads, campus roads, factory roads, etc1. The components of solar street lightsIn terms of appearance and performance, solar street lights are composed of two parts: a lamp pole and a lamp head.The choice of lamp pole will affect the overall safety and usability. The height of the lamp pole needs to be slightly greater than or equal to the width of the road; the thickness of the lamp pole needs to be considered according to the local environment. The thicker the lamp pole, the stronger the wind resistance. Ordinary lamp poles are designed as steel tapered poles, which are beautiful appearance ,durable, simple in processing technology, high in mechanical strength, and easy to make into various shapes. Common lamp pole cross-sections are circular, hexagonal, octagonal, etc. the wall thickness is generally 2.75-5mm.1) When choosing a lamp holder, you need to pay attention to the wattage and the quality of the lamp holder. If the usage rate is high and the lighting area is wide, you need to choose a lamp holder with a higher wattage.2. Service life of solar street lightsThe service life of solar street lights is usually 7-8 years. The service life is mainly limited by the quality of LED lamp beads, controllers, solar panels and batteries. High-quality accessories can greatly extend the service life of solar street lights.The climate and frequency of usage of the solar street light installation location will affect the service life of the solar street light. If the solar street light is in a humid environment for a long time, it will accelerate the aging of the accessories, thereby reducing the service life3. Installation and layout of solar street lights        The installation and layout of solar street lights should be selected according to the width of the road and the proposed lighting requirements. There are three traditional lighting methods: single-sided lighting, double-sided symmetrical lighting and double-sided staggered lighting.       There is no need to lay cables when installing solar street lights, and the construction is convenient and fast. However, due to the particularity of the product, professional installation is still required for the projects and professional guidance and maintenance after installation are also factors that need to be considered when choosing solar street lights.

The government program in Africa helps provide solar street lights to  communities and village.Solar lighting is bringing changes to many areas.The slogan of the project is：“Among all，to be top”In the past, many villagers never left homes after the sun went down. The reason: the streets usually went completely dark at night."We used to be scared. This is a lonely area and wild animals used to come," In addition, fire becomes the only source of light in their lives and a survival tool if necessaryvillager Umesh Chandra Awasthi told reporter.But life changed a lot in this community after solar street lights were set up on the village. "Now we have a free pass to go outdoors after dark. Animals, even the Wild dog and boar would unscrupulous intrude our Living area,don't trouble us any longer," Awasthi said.The addition of the lamps is part of a government program to expand solar energy in the poor areas. Most people living in there and mountainous areas have limited access to the main electrical system.Nationwide about 240 million people lack access to dependable power supplies because of operational issues, inability to pay or other reasons.Government incentives have made solar energy more appealing for local communities because of its low cost. The government pays 100 percent of the cost of the solar lights. People in the villages make up the difference."Now my children can play outside at night ," said Shivani Sharma, a mother of a young son and daughter. "If they have examinations and there is no light, they can even study outside," she added.The solar street lighting is proving so popular that many people now want solar equipment where they live to light up their homes. The villagers say such equipment could especially help needy families who often keep lights off at home to save money.It remains to be seen whether government-supported housetop solar collectors will someday become a reality in the Africa. For now, the villagers are happy to enjoy a new kind of freedom created by light.
