Solar energy is inexhaustible, clean, pollution-free and renewable green energy. Using solar power to generate electricity, unparalleled cleanliness, high security, relative breadth and adequacy of energy, long life and maintenance-free advantages that other conventional energy sources do not have, photovoltaic energy is considered to be the 21st century energy source. The most important new energy source.
solar street light uses sunlight as energy. During the day, the solar panel charges the battery, and the battery supplies power to the light source at night. No complicated and expensive pipeline laying is required. The layout of the lamps can be adjusted arbitrarily. It is safe, energy-saving and pollution-free. , save electricity and maintenance free. Solar energy is a typical stand-alone photovoltaic system, and this is only one aspect of the problem, but it is also a seasonal load that increases as the amount of solar radiation decreases. From the above analysis, it can be seen that the annual winter solstice is the time when the solar radiation is the smallest, that is, the solar cell module generates the least electricity. The annual winter solstice is the shortest day and the longest night, and the road lighting takes the longest time. . At present, in the design of solar street light, everyone is concerned about the lighting problem in continuous cloudy and rainy days. In fact, this problem is relatively easy to solve, as long as the capacity of some batteries is increased. If the road lighting index on the winter solstice is to meet the national standard requirements, unless the power generation of solar modules in spring, summer and autumn is sacrificed, there is no other way. At this time, the efficiency of the system will be very low. There are many people who will not agree with the above point of view; the reason is very simple: installed solar street light, it still works well around the winter solstice. In terms of working principle, solar street light uses solar energy as the light source, and the solar panel will charge the battery during the day. At night, when lighting is required, the battery will start to supply power to the light source. It does not need to lay complicated and expensive power supply lines in use, so that it can be installed in any place and any environment. Its battery uses natural light and can be recycled without external power supply. The source is green and environmentally friendly. When the sunlight is insufficient to a certain extent, solar street light can automatically adjust the switch, truly unattended, all-weather work. In terms of product features, solar street light uses solar energy in the light source. During the day, it can use the solar circuit board to charge the battery in the street lamp, and at night, the battery can supply power to the lamp, which can fully meet the needs of lighting. The solar power source used by solar street light is green and environmentally friendly, and can be seen everywhere in nature, which saves the materials required for laying power supply lines, saves a lot of manpower and material resources, and improves construction efficiency. In addition, solar street light is environmentally friendly, energy saving, consumption reduction, long service life, stable product structure, and has very good social and economic benefits. Whenever night falls, there are many
solar street lights all over the country that automatically light up. Under the illumination of the lights, the night in the village is no longer as dark as before. Everyone who returns late can go home with peace of mind under the guidance of the lights, making it easier to communicate with neighbors. The solar integrated street light not only illuminates the roads in the village, but also illuminates the hearts of everyone.
