Whether it is in the busy city trunk roads, or quiet countryside roads, whether in the busy factory area, or cozy residential neighborhoods, solar street lights with its unique charm, lighting up our night. With its increasingly wide range of applications, the production of solar street lights manufacturers is also springing up. However, the prosperity of the market has also brought about uneven product quality, especially in this emerging field, consumers are often confused when choosing.
So, how exactly should we choose solar street lights and accurately distinguish their advantages and disadvantages? The following four aspects will be the key to your screening: solar panels, solar batteries, solar charge controller and street light head.

As the core component of the solar street light, the quality of the solar panel directly determines the power generation efficiency and service life of the street light. High-quality solar panels usually have high photovoltaic conversion efficiency, and can store enough electricity for the battery in a shorter period of time. At the same time, the material and process should also meet the industry standards to ensure stability and durability in adverse weather conditions. In terms of types solar panels are divided into monocrystalline and polycrystalline. Monocrystalline solar panels are more efficient, less light attenuation, but expensive, polycrystalline solar panels are relatively less efficient, but inexpensive. The power generation capacity of solar panels is closely related to light intensity, ambient temperature, installation angle and so on. Changes in each link will affect its power generation effect. Raw materials, battery components generally include battery cells, eva, backplane, aluminum alloy frame, tempered glass several parts, if you use poor-quality battery cells, it will produce irregularities in the lamination process to produce defects in the copper-tin-copper bending, tightening of the phenomenon; and will produce bubbles, which proves that in the 160-degree high-temperature heating and sealing process will still produce residual gaps, the battery cells are very important to sealing the oxidation, otherwise, in the open air is the sealing of anti-oxidation, the solar panels are very important. The cell is very important to seal anti-oxidation, otherwise in the open air is 1-2 years of service life, including the filling of the border gap, which is a very important part of the process. So the quality of solar panels is very important, must choose the quality assurance, not just the pursuit of low prices.

The battery is a container for storing the electricity converted by the solar panel, and its capacity and performance directly affect the brightness and duration of the street light. We should choose batteries with moderate capacity and stable performance to ensure that the street light can continue to shine continuously and stably at night. At present, the common types of batteries for solar street lights include lead-acid batteries, gel batteries and lithium batteries. Lead-acid and colloid are inexpensive but short-lived, while lithium batteries have more charge/discharge times and longer lifespan, but are expensive. With the development of lithium battery technology, the configuration of lithium battery solar street lamps more and more, but lithium batteries must pay attention to the quality of the choice, may accidentally buy a second-hand battery, because the market has a lot of removed from the tram core into the solar street lamp market.

Charge and discharge controller is the “brain” of the street light system, responsible for regulating and managing the distribution and use of electric energy. High-quality controller should have good stability and reliability, according to the weather conditions and electricity demand to automatically adjust the working state of the street lamp, in order to achieve energy saving and extend the service life of the effect. Currently common controllers are PWM type and MPPT type. MPPT controller, full name Maximum Power Point Tracking (Maximum Power Point Tracking), is a kind of controller used to optimize the output power of solar panels . Its main function is to monitor the power generation voltage of the solar panel in real time and track the maximum voltage and current value (VI). By adjusting the pulse width modulation (PWM) output duty cycle, the MPPT controller is able to make the solar panel always run at the maximum power point, so as to fully utilize the output energy of the solar panel and improve the power conversion efficiency of the solar panel. So MPPT has a higher conversion efficiency compared to PWM, which also means that the solar panels used in solar street lights with MPPT controller can be smaller than those with PWM controller. Of course, MPPT controller is much more expensive than PWM, so we must understand the type of controller when choosing solar street lights. MKLIGHTS, as a manufacturer of solar street lights, understands the importance of the controller, so almost all of our products are using MPPT controller.

Street light as the load of solar energy system, at present there are mainly 4 types of light source, high pressure sodium lamp, metal halide lamp, energy-saving lamps and LED lamps.
Nowadays, LED street light is becoming more and more popular in solar street light due to its energy-saving type. The more energy-efficient the street light head means that the power of the street light head will be smaller when the same brightness is achieved, which will greatly reduce the size of the configuration of the solar photovoltaic panels and solar batteries, thus reducing the purchase cost. As a user, we need to meet the requirements of the lighting needs, so the LED street light efficiency is one of the important factors we must consider. MKLIGHTS from the company’s inception has been committed to the research and development of outdoor LED street lamps, high luminous efficacy of LED street lamps has been the direction of our pursuit, through continuous investment, our LED street lamps are currently able to reach a maximum of 220 LM / W! Light efficiency, which provides unparalleled cost-effective solar street light configuration, interested friends, you can contact MK team to get the latest information.

In summary, by focusing on the four aspects of solar panels, solar batteries, solar controllers and street light heads, we can more accurately discern the advantages and disadvantages of solar street lights, so that we can choose a lighting product for ourselves that is both practical and economical.
