A: yes, we can do that if there is special requirement.
A: Yes, we are manufacturer, focused on qualified solar lighting solutions since 2013
Q: What is the Belt and Road?
A: The Belt and Road is the abbreviation of "Silk Road Economic Belt" and "21 st Century Maritime Silk Road". Belt and Road was proposed by the President in 2013 with the strategic goal of building a community of interests, destiny and responsibility with Asia and Africa and Europe with political mutual trust, economic integration and cultural inclusiveness. The world, including Eurasia, is a community of mutual benefits, destinies and responsibilities.
A: LED street lamp is a kind of solid state cold light source, which has the characteristics of environmental protection and no pollution, less electricity consumption, high light efficiency, long life and so on. Therefore, LED street lamp is the best choice for energy-saving reconstruction of road lighting. Solar streetlights are powered by sunlight, solar panels charge the batteries during the day, and the batteries supply the lights at night, without complicated and expensive pipeline laying. The layout of lamps and lanterns can be adjusted arbitrarily to save energy, save energy and no pollution. No manual operation stable and reliable, save electricity and maintenance.
Q: Which batteries are commonly used for solar street lamps?
A: Shenzhen clodesun photoelectric answer your current solar lamp battery applications are divided into the following: lead-acid batteries: low price, suitable for low temperature and high rate discharge; However, attention should be paid to prevent lead acid pollution, and too heavy, will be phased out of. nickel-cadmium batteries: strong, cheap, economical and durable, good performance at low temperature; However, attention should be paid to prevent cadmium metal from polluting the environment. Ni-MH battery has good charge-discharge performance at high rate and no pollution, so it is a green environmental protection battery. Small system, it is worth strongly advocating. the lithium iron phosphate battery: high temperature performance, large capacity, high charge and discharge efficiency, light weight, environmental protection and no pollution, but its price is too expensive, also has the selectivity to the charge
Q: Advantages and disadvantages of solar street lamp?
A: solar street lamp is relatively safe, using 12V power supply, it is not easy to cause electric shock, then the installation process of solar street lamp is relatively convenient, no tedious line construction, no need to establish antenna or ground cable, Just find the right position, dig trenches to install lights, relatively beautiful and convenient. Secondly, the service life of solar street lamp is generally 5 years. With the progress of photovoltaic technology, the service life of solar street lamp will be longer and longer. Finally, solar energy will be converted into electric energy, energy saving, environmental protection and no pollution. Disadvantages: it may cost a lot of upfront investment, which is considered by many users as the biggest drawback. In fact, compared with ordinary electricity street lamp maintenance costs, the quality of solar street lamps installed after the use of basic no other expenses.
A: How long is the solar street lamp life is ordinary, the street lamp by the road. How long is the lead acid battery 3-5 years (most of the engineering is not good, life is certainly short) LED lamp head, in theory, between 50, 000 to 100000 hours, The theoretical life of the controller is about 8-15 years (affected by electronic components and external use, wet or otherwise, not that long) the solar plate has a life of more than 20 years (as long as no one breaks it, and the top is not dirty. A life span of more than 15 years is no problem).
Q: The voltage of a solar street light？
A: The voltage of a solar street lamp is divided into 12 volts, 24 volts, 36 volts, 48 volts, 72 volts according to the lighting size of the street lamps. 1. How wide the street lights are, how long they work, how many rainy days there will be solar lights of different power. 2. The application of solar street lamp mainly depends on solar panel, and the voltage of solar panel is 17.5 V and 36V. The voltage design of solar panel is 12V and 24V respectively. 3. The solar panel produces direct current, and the voltage from the battery is, of course, 12V/24V/36V, which is the most commonly used specification in solar street lamps. 4. At present, the light sources of solar street lamps on the market are specially designed for solar panels, so the conventional voltage is, 12V/24V/36/, this is the mainstream, and of course there are higher ones, such as 48V/72V and so on.
Q: Why Clodesun advises to use 24V for 40+W Solar LED System?
A: Our suggestion for using 24V battery bank for solar LED system is based on our research which we conducted earlier before launching our Solar LED system.
What we did in our research was that we actually tested both the systems 12V battery bank and as well as 24V battery bank.
A: Batteries are shipped 85% charged. The batteries will be at 100% charged within two weeks of proper operation.
A: Gel battery also known as VRLA (valve regulated lead-acid) batteries or gel cells, contains acid that has been gelled by the addition of silica gel, turning the acid into a solid mass that looks like gooey Jell-O. They contain less acid than a regular battery. Gel batteries are commonly used in wheelchairs, golf carts and marine applications. There are several advantages to using gel batteries.
A: 1, lamp pole: 6 m (normal calibre of 60-140 or 70-140 or 70,150, wall thickness 2.3 or 2.5 or 2.75 or 3.0, flange 240 or 260 "based on base dragon diagonal") 2, Lamp head: 30 watts (there is no reflector in the lamp head, light bead is divided into crystal element, Osram, Prey) 3, battery: full power configuration 45AH18650 ternary lithium battery (there are a lot of batteries on the market, but the layman is not easy to see) 4, Solar panels: full power configuration 80 watts polycrystalline solar panels (solar panels in the market are polycrystalline and single crystal, solar panels are generally difficult to distinguish the size of the true or false) 5, controller: solar street lamp controller, 40 watt booster controller (different price of controller brand)
A: Installing a solar or wind powered LED street light isn’t any sort of rocket science, in fact anyone willing to install by himself can do it easily.
