Solar Street Lamp Controller Design Principle

Solar street lamp controller is the smallest part of the whole solar street lamp system

its cost is also one of the lower parts, but it is a very important part of the whole system, is the control center of the whole solar street lamp system. With the development of the industry, the function of the solar street lamp controller is more and more, and the degree of intelligence is more and more high, so the reasonable and scientific design of solar street lamp controller standards, quality and parameters is very critical. After years of experience in controller development and use, LUXMAN summarized the following principles:

High-quality electronic components

The life of the components determines the life of the solar lamp controller, so the controller must strictly control the raw material incoming inspection, Luxman chose the  Japan Rubycon capacitor, TI chip, the quality of these components is stable,

Accurate parameter setting

Pay attention to the controller and solar street light battery supporting, especially the battery voltage, solar street light controller and solar street light lighting module source matching, solar street light LED module input voltage and solar street light controller output voltage must be consistent. The power distribution of the solar street lamp controller should be reasonable, The lighting time and power of the street lamp should be reasonably distributed according to the power generation and storage capacity of the solar street lamp system.

Note that the lead acid battery solar street light controller and lithium battery  solar street lamp controller is not universal.

Reliable software performance

The performance of the software should be stable. Luxman’s controller software is based on many practical application parameters and feedback settings. The installation environment has a great impact on the lamps. For example, in Japan, Canada, and other countries, the sunshine time in winter is relatively short and the lighting time needs to be longer. Therefore, for different projects and applications, we provide customized program services to ensure that our products are stable.

Reasonable use of the management function

The current solar street lamp controller in addition to the regular function of time control(lights up for 12 hours every night), infrared (people come to light, people go to light out or dim), intelligent management output (the same electricity can ensure that the lights do not go out for a week or a month or even longer). We can also add a camera, Bluetooth connection, support app, pad, computer remote control, etc. these functions must be selected and set according to the needs of users.

How to choose batteries for your solar street lamp project?

Outdoor Solar street lamp battery equipment has a built-in type, Pole mount type, and buried type.

solar street light battery

                             Built-in type                            Buried type                           Pole mount type

Built-in is the lithium battery pack integrated together into the lamp body; If an external pole mount type is selected, it is better to install the equipment on the solar street lamp with a height of 6 meters, and there should be no climbing objects beside the solar-powered streetlamp, also pay attention to anti-theft. If to choose the buried type, it is best to pay attention to anti-theft, waterproof, pouring cement ground to density, and replaceability.

The battery is a very key component of the solar-powered street lights system, and also a major component of the solar-powered street lights system cost. At present, solar street lamps mainly use Gel batteries and lithium batteries.

First, explain the concept of both:

Gel batteries belong to a development classification of lead-acid batteries. The method is to add a gelling agent in sulfuric acid to make the electro liquid of sulfuric acid become colloidal. Electrohydraulic colloidal batteries are commonly referred to as colloidal batteries.


The lithium battery is a kind of lithium metal or lithium alloy as a negative material, using a non-aqueous electrolyte solution, compared to a commonly used colloidal battery, the lithium battery is more environmentally friendly, lightweight and longer life, of course, the price of lithium battery will be slightly higher

The lithium battery is a kind of lithium metal or lithium alloy as a negative material, using a non-aqueous electrolyte solution, compared to a commonly used colloidal battery, the lithium battery is more environmentally friendly, lightweight and longer life, of course, the price of lithium battery will be slightly higher.


Lithium battery

Gel battery, lithium battery have their own characteristics, but in recent years lithium battery solar street lamp systems develop much better, what are their advantages? Let’s briefly compare the differences between the two:


  1. Solar-powered street lights  power supply method:

Lithium battery 12V 120AH storage power, higher than the colloidal battery 12V 120AH storage power, lithium battery can be full of release, lithium battery cycle high life is 3~5 times than the colloidal battery.


  1. The maintenance cost of solar-powered street lights

Gel battery service life in 2-3 years, lithium battery service life in 5~8 years, to ensure almost no maintenance costs.


  1. Are solar-powered street lights environmentally friendly?

Gel battery production pollution is serious, can not be recycled and used, heavy metal pollution is serious, non-environmentally friendly batteries;

The lithium battery is an environmentally friendly battery, lithium belongs to the light element, is harmless to the human body, iron in the soil is ubiquitous.


  1. The material cost of solar led street lights:

Gel battery production technology is difficult, high cost; Lithium-ion batteries are environmentally friendly and cost slightly more than colloidal batteries. But overall accounting down, the lithium battery solar street lamp cost is more cost-effective.

  1. The installation cost of solar led street lights:

Gel battery is relatively bulky, generally need to be buried, must do waterproof anti-theft work, installation labor cost is high, late maintenance cost is also very high; Lithium battery is lightweight, high energy density, generally integrated in the inside of the lamp body or under the solar panel, the battery installation does not need labor costs, the maintenance is simple and convenient.

solar street light design

By comparison, we can see why more and more solar street lamps look less bulky than before, due to the use of lithium batteries. The lithium battery is used in solar street lamp systems, and has the advantages that ordinary Gel solar street lamp battery does not have:

I. The charging and discharging system of lithium batteries generally adopts the integrated structure of lithium battery and controller, which is an energy storage battery system with no pollution.

II. According to the user’s demand, the remaining capacity, operation days and nights, weather conditions, and other factors can be intelligently optimized and calculated, and the power level can be reasonably distributed. The functions of light control, time control, and memory storage, to ensure the intelligent setting of the solar street lamp system.

III,  Lithium battery due to dry battery nature, more stable than Gel battery, safer.

IV,  Lithium battery weight is light, the same capacity specification weight is about 1/6-1/5 of the lead-acid Gel battery;

V,  The environmental adaptability of lithium battery is stronger, the use of a wide temperature range can be used in the -20℃- 60℃ environment, after technical treatment, even can be used in the -45℃ environment, which also provides conditions for the promotion of solar street lamps in cold areas.

Solar LED Street Lights Application Analysis

When Greta Thunberg, a Swedish environmental teenager, chose to sail the Atlantic for two weeks before arriving in New York for the United Nations’ youth climate summit, Luxmanlight employees were actively promoting the use of Integrated Solar LED Street Lights around the world. Different views on the same event just represent our different ideas on environmental protection.

The all in one solar LED street light is the product of modern science and technology development. It directly uses solar energy for power supply, environment-friendly, and energy-saving. With the characteristics of once investment and long-term return, traditional street lamps and an LED street lamp is gradually replaced. The solar street light with an automatic lighting system is generally used for street lighting of urban and rural roads. The intelligent street lighting system can realize the intelligent monitoring and management of street lights and reduce the operation and maintenance cost of the system. Thanks to its stable performance, easy management and no need for electricity connection, it is becoming more and more popular. Solar LED street lamps are used in parks, communities, squares, and parking lots from remote rural areas to cities. According to our customer’s experience, now we summarize the main installation locations of solar street lamps.


Application location of solar LED street lamps

  1. Rural road lighting

The rural natural environment is harsher, not suitable for laying cable. Solar lamp installation is simple, long service life. Moreover, rural roads are narrow and small, and the requirements for LED light sources are not high, which is suitable for installing stand-alone solar LED street lights.

  1. Monitoring and lighting of farms, barns, doorways, and courtyards

House installation of solar street lights not only very convenient night lighting, but also can be equipped with a camera monitoring function. In the meantime, installation is simple, still can save a lot of electricity bills. Current standard configuration with light control, will according to illumination (brightness) automatically turn on-off the light, auto-off in the day, auto-on light at night, very simple and convenient.

  1. Homestay, resort, and hotel outdoor lighting

Lighting safety, environmental protection, and energy-saving are the pursuit of the concept of homestay and hotel, so the solar street lamp is the right choice.

  1. Mining area, remote power shortage place lighting

Mining areas are usually quite remote, so the cost of installing street lamps by cable is very high. Therefore, it is appropriate to choose a solar street lamp. Luxman solar LED street light works 12 hours a night and can support 5-7 rainy days. The road may still be rough, but it is no longer dark and safe to travel.

  1. Island lighting

There is no doubt that islands are short of electricity, especially the remote, smaller islands, which are 100% short of electricity. Diesel power doesn’t work 24/7 and there are always dark hours, but solar lighting will keep your nights dark no matter how windy or rainy.

  1. Monitoring and lighting of the home town villa

Many young people like to live in the city, where the house is only for old people and children or no one lives. Therefore, a kind of solar street light with a camera that can be illuminated and monitored is very suitable for use. like Luxman S3C Series solar street light with a camera for residential areas.

  1. The lighting of urban roads and secondary trunk road

Energy-saving and emission reduction can be achieved not only by using AC Powered LED lighting, but also by using more advanced solar-powered street lighting without electricity bill, which can be invested once and be effective for a long time.

  1. Square, parking lot, playground lighting

There’s a lot of traffic in public places, but it’s usually only in the early hours of the night. The intelligent solar street lamp can do induction mode(PIR), time control mode, and can also do induction + time control hybrid mode, so it can meet the lighting use in public places.

  1. Schools, hospitals and museums outdoor lighting

Environmental protection is everyone’s business. The low-carbon concept must be promoted from schools to hospitals, exhibitions, museums, and another outdoor lighting. Integrated solar street lamps not only meet the lighting needs but also have a prominent environmental protection demonstration effect.

  1. Park and green space lighting

In general, the lighting of parks and green Spaces does not require high illumination on the ground (compared with outdoor stadium lighting). Intelligent solar street lamps are the best choice for lighting in these public areas.

  1. Community road lighting

The lighting of community roads and garden roads in the community has changed from traditional lamps to LED lamps and then to solar street lamps, which is the trend of the times.

  1. Industrial zone, science, and technology park, road lighting

In industrial areas, science and technology parks or innovation incubators park, no matter traditional lighting or LED lighting which used for public electricity, it is not as cost-effective as solar street lamps after cost accounting.

13.Outdoor camping lighting

The installation of LED solar street lamps in some of the best places for camping not only solves the main problem of campers but also ensures their safety to some extent.

In the future, more than 70% of roads and lighting are expected to use solar street lamps, compared with less than 5% today. At present, the price of a solar street lamp is mainly set according to the level of parameter configuration, and the service life is closely related to the configuration. The solar street light manufacturer offers a five-year warranty, which is favored by many customers.

LUXMAN - Solar Panels

What’s the Differences Between Monocrystalline solar panel and Polycrystalline solar panel ?

Solar street lamps usually use two kinds of solar panels, Monocrystalline solar panels, and polycrystalline solar panels. Silicon is the raw material for making solar cells, but it is not easy to extract it. Therefore, while producing monocrystalline solar cells, people also studied polycrystalline solar cells. So how do distinguish monocrystalline solar panels and polycrystalline solar panel correctly?

Firstly: Appearance differences

Looking from the appearance, the four corners of the monocrystalline solar cell are circular, and the surface is not patterned; while the four corners of the polycrystalline cell are square, and the surface is like an ice flower.

Secondly: Usage differences

For users, there is no big difference between monocrystalline solar panels and polycrystalline solar panels. Both of their life and stability are very good. Although the average conversion efficiency of monocrystalline silicon panels is about 1% higher than that of polycrystalline silicon panels, monocrystalline silicon panels can only be made into quasi-square (all sides are circular arcs), some areas of solar panels will not be filled when they are made up; while polycrystalline silicon is square, so there is no such a problem, their advantages, and disadvantages.
