20 watts of solar street light manufacturer1

Rising along with the energy crisis, and increasing awareness of environmental protection, more and more cities in the construction of street lights can choose solar street lights, solar street lamps to achieve real energy conservation and environmental protection is not only the most important technologies for solar

since the energy crisis and the people environmental protection consciousness enhancement, more and more cities are building lights will choose solar street light. Solar street lamps to achieve real energy conservation and environmental protection, the most important technology is not only the absorption of solar energy and conversion technology, and solar electricity after conversion. At present, there are many kinds of batteries, such as nickel, chromium, nickel metal hydride, lithium batteries, etc. And electricity is the best storage performance of lithium battery. Lithium battery as the battery solar street lamps, has the following advantages: high energy storage density, 460 - 600 watts/kg, is 6 - of lead-acid batteries Seven times. Service life is long, can reach more than 6 years. Low self-discharge rate, good store electricity, ensure the solar street lamps lighting at night. High and low temperature flexibility, can be in - 20℃ - 60 ℃ under the environment of use, so as to adapt to different environment, guarantee the normal operation. The most important thing is that the green environmental protection of lithium-ion batteries, do not contain or does not produce any poisonous and harmful heavy metal elements and substances, such as lead, mercury and cadmium, regardless of the production, use and scrap. For many, the lithium battery has so many advantages, solar street lamps, but how about the price? In fact, our lithium battery technology is relatively mature solar street lamps, not only the quality of the finished product is higher, and the price is relatively cheaper than traditional street lamps, and environmental protection and energy saving. At present, shandong street lamp lighting factory co. , LTD. , independent research and development of new type high power led lamps and lanterns, outdoor lighting lamps and lanterns of various kinds of styles. And has a number of patented products. If you want to know the particular value of lithium battery solar lamp, you can contact us for detailed consulting or research project.
