Solar street lamps are powered by crystalline silicon solar cells, maintenance free lithium batteries, ultra bright LED lamps as light sources, and controlled by intelligent charge and discharge controller. There is no need to lay cables, and the subsequent installation is very simple; No AC power supply and no electricity charge; DC power supply and control are adopted. Solar lamps have occupied a large proportion in the lighting market.
However, since there has been no specific industry standard in the solar lamp market, many friends often ask how to choose high-quality solar street lamps?
As a person in the industry, I have summarized several aspects. When I choose these, I can choose satisfactory products.
1. To understand the solar street lamp LED components, there are more detailed varieties of components, mainly including solar panels, batteries, controllers, light sources and other corresponding components.
Every accessory has many things to say. I'll summarize them here.
Solar panels: polycrystalline and single crystal are common in the market. It can be directly judged from the appearance. 70% of the market are polycrystalline, with blue ice flowers on the appearance, and single crystal is solid color.
However, this is not too important. After all, the two have their own advantages. The conversion rate of polycrystalline silicon is a little lower, and the average conversion efficiency of monocrystalline silicon cells is about 1% higher than polycrystalline silicon. However, because monocrystalline silicon cells can only be made into quasi squares (all four sides are circular arcs), when forming solar cell panels, some areas will be filled up; Polysilicon is square, so there is no such problem.
Battery: it is recommended to buy lithium iron phosphate battery (lithium battery). The other is lead-acid battery. Lead-acid battery is not resistant to high temperature, which is easy to cause liquid leakage. Lithium battery is resistant to high temperature, but relatively not resistant to low temperature. The conversion rate is low at low temperature. You see the regional choice. Generally speaking, the conversion rate and safety of lithium batteries are higher than those of lead-acid batteries.
Using lithium iron phosphate battery, the charging and discharging speed will be faster, the safety factor will be high, it is more durable than long-life lead-acid battery, and its service life will be almost six times longer than that of lead-acid battery.
Controller: there are many controllers on the market now. I personally recommend new technologies, such as MPPT control. At present, the better MPPT controller in China is the solar controller produced by Zhongyi technology. The MPPT charging technology makes the efficiency of the solar power generation system 50% higher than that of the traditional one to realize efficient charging. It is widely used in domestic small and medium-sized solar street lamp systems and small and medium-sized off grid solar power plants. Due to its high quality and practicality, it has a very high share in the domestic photovoltaic market.
Light source: select high-quality lamp beads, which directly affect the illumination and stability of the lamp, which is an extremely important existence. Riya lamp beads are recommended. The energy consumption is 80% less than that of incandescent lamps with the same light efficiency. The light source is stable and uniform without flicker, high efficiency and energy saving, low heat, high color rendering, long service life and high luminous efficiency. The daily illumination is twice as high as that of traditional street lamps, up to 25LUX!
2. Lamp shell: hot galvanizing and cold galvanizing are common in the market, which can be judged by the naked eye. Hot dip galvanizing still has coating on the notch, and cold galvanizing has no coating on the notch. Hot dip galvanizing is common in the market, which is not easy to choose. The main reason is that hot dip galvanizing is more anti-corrosion and anti rust.
3. Appearance: to see the overall LED of solar street lamp is to see whether the shape and workmanship of solar street lamp are beautiful and whether there is any skew problem. This is the basic requirement of solar street lamp.
4. Pay attention to the manufacturer's warranty. At present, the warranty on the market is generally 1-3 years, and the warranty of our factory is 5 years. You can click the website to inquire and contact me. Try to choose one with a long warranty period. Ask about the warranty policy. If the lamp breaks down, how can the manufacturer repair it, whether to send the new one directly or send the old one back for maintenance, how to calculate the freight, and so on.
5. Try to buy goods from the manufacturer. Most of the merchants settled in e-commerce are middlemen, so we should pay attention to screening. Because the middleman may change other products after one or two years, it is difficult to guarantee the after-sales service. The manufacturer is relatively better. You can get the manufacturer's name to the enterprise and check it to see how much the manufacturer's registered capital is. The registered capital for street lamps is relatively small, ranging from hundreds of thousands to millions, and tens of millions. If you pay attention to quality and need solar street lamps with high quality and long service life (8-10 years), you can click the website to inquire and contact me. Especially for engineering, try to choose manufacturers with a registered capital of more than 50 million.
Choosing solar street lamp manufacturers with high popularity of large brands, such as TianXiang Co., Ltd. solar street lamps, can often be guaranteed in many aspects and convenient after-sales. For example, there are professional production equipment, testing equipment and automation equipment, technical team, etc., which can reduce the worries of buyers.
Welcome to communicate with me. We are committed to sharing the knowledge of solar street lamps, so that users can really understand this product, so as to cross the market trap and buy solar street lamps with high cost performance.
