There are many factors that can affect the performance of solar led street lights. Any problems in any of the links will result in product defects Or additional costs.

The main 5 reasons that affect the function of solar street lights are : 1,Solar panel 2, solar battery light source) 3, the outer shell design 4, led chips (LED) 5,install
 

The solar panel account 20% – 30% of the solar street lights cost. There are two main types solar panel in the market : Monocrystalline solar panel and polycrystalline solar panel .
Following are the simple comparation of these two types solar panels:

21. Mono solar panel : 18%-24% conversion        10-15 years life span           $0.5-$1/w
21. Poly solar panel : 14%-16% conversion         15-20 years life span          $0.25-$0.6/w

And the mono solar panel performs better in rainy days than the poly solar panel.That is the main reason we advice using Mono solar panel in solar street lights.And because mono solar panel can get a bigger power in the same size, all the integrated solar street lights ( all in one solar street lights, smart solar street lights) use mono solar panel.
Monocrystalline silicon also Classified by level by grade A, grade B, grade C, grade A polysilicon, grade B, grade C, grade A polysilicon, grade B, grade C, class A conversion efficiency up to 16%, B times in class C The C grade is lower than 8%, the conversion efficiency is high, and the conversion efficiency is low.

But by 2020 , there are still a lot Manufactureries using polycrystalline solar panel and Low-grade solar panels for outdoor solar lighting system .

Therefore, when you want to buy, you need to explicitly generate the requirements for solar panels (photovoltaic modules, power strips) and choose the right level of solar panels.

Cmoonlight always choose to use high efficiency A grade monocrystalline solar panel but not the polycrystalline and low grade solar panel .
 

The biggest advantage of Cmoonlight is that we use 10-15 years long life A-grade LiFePo4 Lithium batteries (the same type of battery used in hybrid cars, pay attention to the car does not start the car), Cmoonlight integrated solar street light has a long life of  8 years. It is the world’s first lithium battery management and control technology. Compared with some ordinary battery products that need to be replaced within two years, the future after-sales service cost and component replacement integrated solar street light can be decrease very much. Usually, it is not necessary to replace the battery or maintenance within 8 years. Even if it needs to be replaced after 8 years, due to our unique product structure design, users can replace it in just a few minutes, without the support of technical support and engineers.

 3. Solar light outer shell design

 Cmoonlight engineers spent more than a year to design this world unique appearance all in one solar street light to improve the energy efficiency.

50. Solar panel could rise up and fold, which is better for solar panel face the sun direction in both side of road.
50. Good heat dissipation: Separated solar panels can shade lamp body, they will not conduct heat to each other,makes the lamp body cool, enlarge lifespan and eciency of battery and LED source.Easier installation-no power required, no cables required, 2 mounting step.

 Thanks to the innovative design, Solar panel efficiency can be increased by 60%, Effectively prolong the service life and efficiency of lithium battery and LED light source. all the core components of the solar light and the smart body sensor are integrated into an elegant and light shape, reducing the energy efficiency of the lighting and energy consumption.

 4.LED lights chip

 We all know that LED operating voltage is low, very suitable for application in solar lights. LED light sources are divided into small power single integrated and high power single integrated types.

 From the perspective of chip manufacturers, it is divided into imported chips and domestic chips, such as US Puri, Cree,South Korea, Samsung, Taiwan wafers, etc., Acer, Putian, etc.,

luminous efficiency is 80-100 Lm / W, large Lm / W value, high Luminous efficiency and low Lm / W values. High quality lamp beads have a long life span of 5,000-100,000 hours or more and a light decay of less than 15%. The poor quality lamps are short in quality and short in life. In general, light decay will drop by 30% after one year, which means that after a year, it will not basically light up.

At present, some people say that the number of lamps with good quality and the number of lamps with poor quality are sold on the market. It can be seen that the choice of good components is critical to the LED light source. Cmoonlight choose the import high luminous efficacy US Cree LED chip.

 5.Install

Cmoonlight integrated solar street lights is the cost savings of installation and commissioning, as well as product shipping costs. The advantages of integrated solar street lights are simple installation and light weight. Usually, two workers do not use heavy equipment and tools. Below, you can complete the installation in 5 minutes with just one wrench in one product. Low installation and maintenance costs typically use only one-fifth the cost of traditional luminaires. If you export it abroad, you only need 1/10 cost of the traditional split solar street light. 

Since 2008, the renewable energy sector has experienced exponential growth.
Every day, more and more companies are operating in this field especially after the increase of the demand for solar led street lights, economical and renewable systems that allow a reduction of the costs in terms of energy used. Many times we are often deceived by very low prices and fast solutions. 

As a new star industry, the solar street light industry lacks industry standards. In the production process of solar street lights, the industry has a low barrier to entry. Many small enterprises directly purchase low-quality raw materials to assemble solar street lamps at low cost. In the process, they also cut corners and shoddy products, which seriously affect the performance and service life of the products. The lack of mandatory inspection standards has made many companies profit-seeking and dismissive of product quality. 

Cmoonlight Resolutely use the highest quality solar integrated street light accessories to win the trust of customers, we believe we will be more and more competitive in the future.
