Solar energy is inexhaustible, an inexhaustible, clean pollution-free green and renewable energy. Using solar power, incomparable clean, high security, energy is relatively extensive and adequacy, long life and free maintenance, and other

the solar energy is an inexhaustible, an inexhaustible, clean non-polluting, renewable green energy. Use of solar energy power generation has the incomparable advantages of other conventional sources of energy, such as cleaning, high safety, energy is relatively rich, long service life, maintenance free, etc. Solar energy is considered to be one of the most important new energy in the 21st century. The present invention USES sunlight as an energy source, solar panels during the day to battery, battery for power supply, light source in the evening does not require complicated, expensive plumbing, can adjust the layout of the lamp, safety and energy saving no pollution, no need manual operation, stable and reliable work, saving electricity, maintenance free. Solar energy is a typical independent photovoltaic power generation systems. This is only one aspect of the problem. What's more, it is also with the increase of solar radiation decreased the seasonal load. Can be seen from the above analysis, the winter solstice is the smallest solar radiation time of year, that is, when the minimum solar cell module generating capacity, the winter solstice is the shortest day of the year, the longest night, longest road lighting. At present, in the design of solar street lights, everyone is very concerned about the lighting of consecutive rainy days. In fact, this problem better. Only need to add some of your battery capacity. If winter solstice road lighting indicators to achieve the requirements of national standard, in addition to sacrifice solar modules in the spring, summer, autumn three season electricity, no choice. The efficiency of the system will be very low. Many people do not agree with this view. The reason is simple: after installed solar street light, they can still work properly before, during, and after the winter solstice. In principle, to use solar energy as solar street lamps light source, solar panels during the day to battery. In the evening, when need lighting, battery will begin to supply power to light source. When used, solar street lamp does not require complicated, expensive laid the power cord, can be installed in any location of any environment; The battery solar street lamps use natural light, recyclable, does not require an external power supply, green environmental protection; When enough sunlight to a certain extent, solar street lights will automatically adjust the switch, truly there is no protection and all-weather work. In terms of product features, solar street light on the light source to use solar energy. During the day, it can use solar battery charging circuit board to the street lamp. In the evening, can give the lamp power supply, battery can meet the needs of the lighting. Solar street lamps use solar power of green environmental protection, are ubiquitous in nature, saves laid material needed for the power supply circuit, save a lot of manpower material resources, improve the efficiency of the construction. In addition, the solar street light environmental protection, energy conservation and reducing consumption, long service life and stability of product structure, has the very good social benefits and economic benefits. When night came, the whole nation many solar street light will light up automatically. Under the lights, the night of the village is no longer as before dark. Under the guidance of light, everyone if they can be at ease to go home, let the neighbors more convenient communication. Solar street lamps lit up the village road not only, also lit up the hearts of every citizen.
