According to a new study, the market for solar streetlights is expected to reach 7530 million USD in 2023 from 2950 million USD in 2017. The Asia Pacific market for solar streetlights is expected to be the market with the most promising growth rate in near future. The rise in per capita income in emerging economies such as China, Thailand, Vietnam, the Philippines, and India has led to an increase in demand for this product.
In terms of solar energy production, this region is at the top of the world. As per the experts from the International Energy Agency (IEA), China accounted for around 42.8% of the total installed capacity of photovoltaic panels in the world during the year 2018.
As per the National Renewable Energy Laboratory (NREL), the purchase cost of solar panel saw a significant decrease, cutting the cost down by 80% from 1980 to 2010. Between 2015 to2019, the prices of solar panels declined by another 50% from $0.70/Watt to $0.35/W. This is one of the major contributing factors in increasing the demand of solar streetlights globally, Which will take the market growth from $5.7 billion in 2019 to $14.6 billion by 2030, at a rate of 9.4% between 2020 and 2030.
Future Trends
The outdoor lighting market is going to be dominated by the APAC region and is expected to retain its pace throughout the coming years. This can be attributed to the population growth in the region and also because of sustained growth in urbanization.
Use of solar street lighting system is expected to be higher in the future.
Because developing countries will start focusing on a decentralized power system (off-grid) like solar. This will in turn boost the growth of the market. The constant increase in energy cost and the rise in demand for electricity has already induced the will in a government institution to move towards the development of partnerships with international organizations and regional non-government organizations.

Solar outdoor security cameras harness power from the sun and are used to provide 24 hours of surveillance without relying on electricity. It uses the solar panel to convert energy from the sun and uses that to power the camera without the need for electric sources or cables. The whole system is self-sufficient and only rely on natural resource to charge which means no subscription charges or monthly fees.
A solar-powered security camera is a good option at places where running cables would be expensive and impossible, such as construction sites, remote areas like rural farms, barns, etc. The complete system includes solar panels, cameras, and rechargeable batteries.
How do Solar powered security cameras work?
Solar cameras use high-grade solar panels to convert the sunlight into direct current (DC). An inverter is used to convert DC into alternating current (AC) which is then used to power solar cameras and batteries for continued use. The excess power created by solar panels is stored in these rechargeable batteries which act as a power source during the night when there is no sunlight. Contrary to the most common belief that solar camera doesn’t work during cloudy and rainy days, there is always some amount of light that can pass through rain and clouds and can be used to power the system.
But undoubtedly, the efficiency of the system will decrease during rainy or cloudy days to some extent. Moreover, the system comes with a weatherproof design that can withstand extreme conditions. Some models also come with dust-proof treated with UV protection, or a canopy that allows the camera to take clear visuals while it’s raining.
The amount of electricity that a solar panel for an outdoor solar security camera can generate depends on several factors like the orientation of the panel, average sun exposure, weather conditions, etc. In order to maximize the output power of the system, place the solar panel perpendicular to the sunlight, and the tilt of the panel should be adjusted in a way to have maximum exposure to the sun during peak hours.
The system should be kept away from the places where there is enough shade throughout the day and should be installed away from obstacles that can block the sunlight. Wiping the surface of the panels regularly can help to improve its performance. Though some panels also come with auto-cleaning wipers that can do this work autonomously.
Increase in Demand over the last few years
Since it operates on a clean power source, the system is gaining traction in many countries as the public is more inclined towards adapting environmental solutions these days.
In order to encourage people to adopt solar-powered technologies, the government of various countries such as the US, UK, Canada, etc., are offering incentives as a means to motivate people towards using these technologies. According to numbers, the price of solar, including a solar-powered camera system has decreased by 70% while the number of adoptions has increased by 6000% from 2005 to 2014.

The sun is the primary source of earth’s energy. Solar energy is the energy that comes directly from the sun. It is also referred to as solar radiation. Solar energy reaches the surface of the earth in the form of rays of sunlight. These rays are a form of electromagnetic radiation. Solar energy offers a clean and renewable source of power. The solar panel is the technology that harnesses the power of the sun and makes it useable in the form of electricity. This solar energy will continue as long as we have sun glowing in our solar system, which is another 5 billion years.
The potential for solar energy is enormous as about 200,000 times the world’s daily electric generating capacity is received by the earth in the form of solar energy. Briefly, the amount of sunlight that strikes the earth’s surface in an hour and a half is enough to power the entire earth’s consumption for one year.
What are solar panels and how do they work
The solar panels are photovoltaic cells (also known as solar cells), which are made of semiconductors (a substance that can conduct electricity under some conditions but not others) material usually silicon. Other examples of semiconductor materials employed in solar panels include gallium arsenide, indium phosphide, and copper indium selenide. To make a solar cell, it needs trillions of silicon atoms in the form of a wafer layer. Each silicon atom contains extremely small and tiny things called electrons. These tiny electrons carry an electric charge. When sunlight hits the cells, the photons present in the sunlight will let the electrons loose from their atoms, and as the electron flow through the cell, they produce electricity.
In order to have extra electrons, the manufacturers usually seed phosphorus into the top layer of silicon, with a negative charge to that layer. Similarly, the bottom layer is dosed with boron, which results in positively charged electrons. This all adds up to an electric field established at the ends of silicon layers.
Metal conductive plates on the sides of the cell help to collect electrons and transfer them to wire where they flow like any other source of electricity. The panels should be mounted perpendicular to the arc of the sun to maximize usefulness.
Depending on the sunshine, if it’s bright, then a lot of electrons will get knocked causing lots of electric currents to flow. In case if it’s cloudy there will be a small number of moving electrons so the current will be reduced.
At night, since there is no sunlight, the solar panel produces no electric power and we need to rely on batteries to keep the lights on.
In a well-balanced configuration, the solar array is capable of generating enough power during the day that can also be used during the night. The solar array sends direct current (DC) electricity through the charge controller to the battery bank. The inverter then draws the power from the battery bank and converts it from direct current to alternating current (AC). The AC current can further be used to power loads in homes or commercial buildings.
Solarmodul Efficiency
Each photovoltaic module of the solar panel is rated by its DC output power under standard conditions. The typical power range is between 100 to 365W. The efficiency of a module at a given same rated output determines the area of the module. An 8 percent efficient 230W module will have twice the area of 16% efficient 230W module.
A single module can produce only a limited amount of power. Which is why most installations contain multiple modules adding voltages and current to the system. Solar cells are arranged into a large grouping called arrays and these arrays are composed of many thousands of individual modules that function as central electric power stations. Currently, the best sunlight conversion rate achieved is around 21.5%.
Benefits of Solar Panels
One of the greatest benefits of solar panels is that they provide clean energy. With the advent of climate change, the world is now shifting towards renewable sources of energy, and solar is being looked as a good alternate. Using renewable sources of power like the sun would reduce the pressure on the atmosphere which is caused by the release of greenhouse gases.
Solar energy is an unlimited renewable energy source. It has the least negative impact on the environment compared to other sources of power being used in the world. It neither produces greenhouse gases nor it pollutes the water. Solar energy production doesn’t create any noise, which is a great benefit for the urban population.
Solar energy can be deployed anywhere in the world as long as there is sunshine. This is particularly useful for remote areas which have no access to any source of electricity. A vast majority of the world’s population lives in places where they don’t have access to electricity, independent solutions could be deployed in these areas which can create a positive impact on millions of lives.
Solar energy production also offers fewer power losses. Some of the energy is lost when there is a distance between the production and supply lines, the greater the distance, the more energy is lost. Having solar panels directly connected to lights or over the roof eliminates those losses.
The installation of solar panels is easy and simplistic, which means it can be installed anywhere, taking advantage of both vertical and horizontal spaces. This aspect facilitates the installation of small-scale projects.
The production of energy from the sun significantly reduces costs. As this is an inexhaustible source of energy that isn’t subject to market fluctuation. The recent development has significantly dropped the prices of components used in the manufacturing of solar panels and made it relatively cheap and affordable in recent years.
Solar panels have no moving parts, it requires less maintenance and can last for decades when properly maintained. Once the system has paid for its installation cost, it produces free electricity for the remainder of the system’s lifespan and that could be around 15-20 years.

（3） Li-ion Battery classification
Lithium batteries can be divided into two categories: disposable non-rechargeable batteries and rechargeable batteries (also known as a battery).
Non-rechargeable batteries such as lithium manganese dioxide batteries, lithium sulfimide batteries.
Rechargeable batteries can be divided into the following categories according to different situations.
According to appearance: square lithium battery (such as ordinary mobile phone battery) and cylindrical lithium battery (such as 18650 of electric tools);
According to the outsourcing materials: aluminum shell lithium battery, steel shell lithium battery, and soft bag battery.
According to the cathode materials, lithium cobaltic acid (LiCoO2), lithium manganate (LiMn2O4), lithium ternary (linixcoymnzo2), and lithium iron phosphate (LiFePO4);
According to the state of electrolyte: lithium-ion battery (LIB) and polymer battery (PLB);
According to usage: general battery and power battery.
According to performance characteristics: high capacity battery, high-rate battery, high-temperature battery, low-temperature battery, etc.
（4） Explanation of common terms
Capacity
It refers to the amount of electricity that can be obtained from lithium battery under certain discharge conditions.
We know in high school physics that the formula of electric quantity is q = I * t, the unit is Coulomb, and the unit of battery capacity is specified as Ah (ampere-hour) or mAh (milliampere-hour). This means that a battery of 1Ah can be discharged for 1 hour with a current of 1A when it is fully charged.
In the past, the battery of Nokia’s old mobile phone (like bl-5c) was generally 500mah. Now, the current smartphone battery is 800-1900mah, the battery of the electric bicycle is generally 10-20ah, and the battery of the electric vehicles is generally 20-200ah.
Charge rate / discharge rate
It indicates how much current is used for charging and discharging. It is generally calculated by the multiple of the nominal capacity of the battery, which is generally called “several C”.
For a battery with a capacity of 1500mah, 1c = 1500mah is specified. If discharging at 2c,it means discharging at 3000ma current. Charging and discharging at 0.1c means it is charging and discharging at 150mA current.
Voltage (OCV: open circuit voltage)
The battery voltage generally refers to the nominal voltage of lithium battery (also known as rated voltage). The nominal voltage of ordinary lithium battery is generally 3.7V, we also call its voltage platform 3.7V. When we say voltage, we generally mean the open-circuit voltage of the battery.
When the capacity of the battery is 20-80%, the voltage is concentrated around 3.7V (3.6-3.9v), when the capacity is too high or too low, and the voltage changes greatly.
Energy/power
When the battery is discharged according to a certain standard, the energy (E) that the battery can discharge is Wh (watt-hour) or kWh (kilowatt-hour), and 1kwh = 1-kilowatt hour.
The physics book has a basic concept, e = u * I * t, which is also equal to the battery voltage times the battery capacity.
The formula of power is p = u * I = E / T, which represents the energy that can be released per unit time. The unit is w (W) or kW (kW).
For a battery with a capacity of 1500mah, the nominal voltage is generally 3.7V, so the corresponding energy is 5.55wh.
Resistance
Since charging and discharging cannot be equivalent to an ideal power supply because of certain internal resistance. The internal resistance consumes energy. The smaller the internal resistance, the better it is.
The unit of battery internal resistance is milliohm (m Ω).
Generally, the internal resistance of a battery consists of ohmic internal resistance and a polarized internal resistance. The size of the internal resistance is affected by the material, manufacturing process and the structure of the battery.
Cycle life
Once the battery is charged and discharged, it is called a cycle, and the cycle life is an important indicator to measure the battery life performance.
According to IEC standard, the lithium battery of the mobile phone shall be discharged to 3.0V at 0.2C and charged to 4.2V at 1C. The battery capacity shall be maintained above 60% of the initial capacity after 500 cycles. In other words, the cycle life of lithium battery is 500 times.
According to the national standard, the capacity shall remain at 70% of the initial capacity after 300 cycles.
If the battery capacity is less than 60% of the initial capacity, it is generally considered to be scrapped.
DOD: depth of discharger
It is defined as the percentage of the rated capacity released by the battery.
Generally, the deeper the discharge depth is, the shorter the battery life is.
Cut off voltage
The termination voltage is divided into charging termination voltage and discharging termination voltage, that is, the voltage at which the battery cannot continue to be charged or discharged. If the battery is continued to be charged or discharged at the termination voltage, the battery life is going to be greatly affected.
The charge-discharge termination voltage of lithium battery is 4.2V and 3.0V respectively.
It is strictly prohibited to charge or discharge lithium batteries beyond the termination voltage.
Self-discharge
It refers to the rate of decrease in capacity during storage, expressed as the percentage of capacity decrease per unit time.
The self-discharge rate of general lithium battery is 2% ~ 9% / month.
SOC (State of Charge)
This refers to the percentage of the remaining power of the battery and the total power that can be discharged, 0 ~ 100%. Reflect the remaining battery power.
（5） Li-ion Battery naming rules
Different Batterie manufacturers have different naming rules, but we all follow a unified standard for general batteries. The size of the battery can be known according to the name of the battery
According to IEC61960, the rules for cylindrical and square batteries are as follows:
Cylindrical battery, 3 letters followed by 5 numbers,
Three letters, the first letter represents the negative electrode material, I means there is a built-in lithium-ion, L represents the lithium metal or lithium alloy electrode. The second letter indicates the positive electrode material, C indicates cobalt, n indicates nickel, m indicates manganese, and V indicates vanadium. The third letter is R for a cylinder.5 digits, the first 2 digits represent the diameter, the last 3 digits represent the height, all in mm.
Square battery, 6 digits after 3 letters,
Three letters. The first two letters have the same meaning as a cylinder. The last one is p, which means square.
There are six digits, the first two digits indicate the thickness, the middle indicates the width, the last two indicate the height (length), the unit is also mm.
For example, ICR 18650 is a universal 18650 cylindrical battery with a diameter of 18mm and a height of 65mm;
ICP 053353 is a square battery with a thickness of 5mm, a width of 33mm, and a height (length) of 53mm.
（6） Li-ion Battery technology
There are some differences in the process flow of different batteries and different manufacturers, and the detailed process flow will be very complex. The basic process flow, the process flow of cell manufacturing and the process flow of pack manufacturing are listed below.
The production process of an electric cell mainly includes pole piece manufacturing, electric cell manufacturing, battery assembly, liquid injection, chemical formation, separation, and other processes.
From batching to winding, the positive and negative electrodes are made in different workshops at the same time. After the positive and negative electrodes are made, the subsequent processes are done together. Different QA links of quality inspection will be inserted in the middle.
（7） Group and series-parallel connection of Li-ion Battery
In different fields, the requirements for batteries are different. The system has some special requirements for voltage, capacity, internal resistance, etc. often a single battery cannot meet the requirements, it needs to be connected in series and parallel to supply power to the outside.
The performance of batteries in series and in parallel is determined by the performance of the worst battery, which is often referred to as the “barrel principle”. Therefore, the most important point of battery grouping is the consistency of battery performance parameters.
For example, a notebook, electric bicycle, electric vehicle, energy storage system, etc. all need to consider the series and parallel connection of the batteries to form a battery pack.
The battery voltage of the notebook is generally 11.1v or 14.8V, mainly 18650 batteries, so it is generally 2 series and 3 parallel or 2 series and 4 parallel.
Apple iPad is three polymer batteries connected in parallel, with a capacity of about 25wh.
The electric bicycle and electric motorcycle systems are generally 24V, 36V, 48V, 60V, and 72V systems. See the following table for specific group conditions (s represents a series connection).
Pure electric vehicles and hybrid electric vehicles (EV / PHEV) have a higher voltage, about 250 ~ 500V, and the maximum voltage will be more than 150 knots connected in series.
In addition, there are many things to be considered in the grouping of batteries in a series-parallel connection, such as the consistency of the battery voltage platform, the consistency of the battery capacity, the consistency of the internal resistance of the battery, etc.
The consistency of battery parameters after a series-parallel connection has a great influence on the performance and life of the battery.

Due to the particularity of the power battery, there are some differences in its process and materials. According to the situation of positive electrode materials, it is mainly divided into lithium manganate (LiMn2O4), lithium ternary (linixcoymnzo2), lithium iron phosphate (LiFePO4), etc. its voltage platform, energy density, price, safety, etc. all have certain differences. See the comparison in the table below for details:

（9） Lithium battery model
In terms of electrical characteristics, the internal resistance of the battery is not completely equivalent to a resistor. For details, please refer to the foreign PNGV equivalent circuit model. As shown in the figure below.
The internal resistance of the battery is mainly composed of ohmic resistance R0 and polarization resistance R1, where C1 is the polarization capacitance.
There are two main test methods for battery internal resistance measurement in the industry. The DC discharge method and the AC injection method, which cannot be measured by the ordinary method of measuring resistance, but can only be measures by the special internal resistance measuring instrument.
The internal resistance of the battery is an important parameter reflecting the performance and life of the battery. When the cycle life of the battery approaches, the internal resistance of the battery increases sharply. The relationship between the number of cycles and the internal resistance is shown in the figure below.
10） Electrical characteristics and key parameters of Li-ion Battery
The charge-discharge curve of the battery
The charge and discharge curve of lithium battery refers to the relationship curve between battery capacity and the open-circuit voltage. According to the discharge curve, the battery’s power can be roughly estimated, as shown in the figure below.
The charge-discharge curve of lithium battery is not only related to the charging and discharging current but also to the temperature. As shown in the figure below.
Key parameters of the battery
Due to its own characteristics, lithium battery cannot be overcharged, over-discharge, over-current, or over temperature. Therefore, considering safety and battery life, the battery should be properly protected. There are several parameters that are often encountered, and they are listed in parallel. There is little difference in voltage between different manufacturers. However, there will be some differences between batteries with different operating temperatures, different discharge rates or different manufacturers.

11） Li-ion Battery protection and management requirements and systems
Due to the characteristics of lithium batteries, it is necessary to add a battery protection board (PCM) or a battery management system (BMS). Batteries without a protection board or management system are prohibited to use, and there will be huge safety risks. Safety is always the first priority for battery systems.
If the battery is not well protected or managed, there may be a risk of a shortened life, damage, or explosion.
The PCM (power circuit module) is mainly used in consumer products such as mobile phones and notebooks.
Battery management system (BMS) is mainly used in power batteries, such as electric vehicles, electric bicycles, energy storage, and other large-scale systems.
The main functions of PCM include OVP, UVP, OTP, OCP, etc. In case of any abnormality, the system will cut off automatically to ensure the safety of the system.
The battery protection system technology is very mature, there are many related board factories, mainly concentrated in South China. And there are special IC manufacturers providing special lithium battery protection chips. This piece is relatively mature, and there are many mature protection IC chips in China.
In addition to the basic protection functions of the protection system, the main functions of the battery management system (BMS) include battery voltage, temperature, and current measurement, energy balance, SOC calculation and display, abnormal alarm, charge and discharge management, communication, etc. Some BMS systems also integrate heat management, battery heating, battery health status (soh) analysis, insulation resistance measurement, etc.
Introduction and analysis of BMS function:
Battery protection is similar to PCM, which includes overcharge, over-discharge, over-temperature, over current, and short circuit protection. Like ordinary lithium manganese battery and ternary lithium battery, once the voltage of any battery exceeds 4.2V or the voltage of any battery falls lower than 3.0V, the system will automatically cut off the charging or discharging circuit. If the temperature of the battery exceeds the working temperature of the battery or the current is greater than the discharge current of the battery, the system will automatically cut off the current path to ensure the safety of the battery and the system.
Energy balance of the whole battery pack after working for a certain period of time will show great differences that could be, due to having many batteries in series, due to the inconsistency of the cell itself, the inconsistency of working temperature or other reasons., This has a great impact on the life of the battery and the use of the system. Energy balance is to make up for the differences between individual cells to do some active or passive charge or discharge management to ensure battery consistency and prolong battery life.
There are two kinds of methods in the industry: passive equalization and active equalization. Passive equalization is mainly to balance the amount of power that is consumed by resistance. The active equalization is mainly to transfer the power of batteries with more power to less powerful batteries through capacitance, inductance or transformer. The comparison of passive and active equalization is shown in the table below.
Because the active equilibrium system is relatively complex and the cost is relatively high, the mainstream is still passive equilibrium.

SOC calculation, battery power calculation is a very important part of BMS, many systems need to know the remaining power more accurately. Due to the development of technology, there are many methods for SoC calculation. If the accuracy requirements are not high, the residual power can be judged according to the battery voltage. The main and accurate methods are the current integration method (also called ah method), q = ∫ I DT, internal resistance method, neural network method, Kalman filter method, etc. The current mainstream in the industry is still the current scoring method.
Communication. Different systems have different requirements for communication interfaces. The mainstream communication interfaces are SPI, I2C, can, RS485, etc. The automobile and energy storage systems are mainly can and RS485.
Due to the insufficient competition and the complexity of the BMS system, there are relatively few system manufacturers. The related chip manufacturers are mainly European and American manufacturers, and there are a few large companies in China as well. There are many opportunities in the future.
I hope that I can send an email to communicate with you about the technology, products, and manufacturers in BMS.
（12） Li-ion Battery charging requirements and systems
The mainstream charging method of lithium battery is constant current and constant voltage (CC / CV): constant current – constant voltage. The constant current if charged first and then the constant voltage is charged after reaching a certain potential.. A good charger can also trickle according to the battery voltage state. Some systems also add pulse charging mode in the back and set the end of charging according to the time.
General chargers integrate functions such as current limiting, voltage limiting, overvoltage protection, overcurrent protection, overtemperature protection, and anti-reverse connection. The specific charging system is shown in the figure below.
In addition, the charger charging is usually combined with PCM or BMS to do energy balance in the constant voltage charging stage.
For an ordinary lithium cobalt oxide battery, if the battery voltage is lower than 3.0V, the charger will start trickle charging (about 0.1C) to avoid damage to the battery. When the battery voltage is charged to 3.0V, it is changed to constant current charging (about 1C, the current depends on the system). It is detected that the battery voltage is converted to constant voltage charging when the battery voltage reaches 4.1V. When the battery current drops to about 0.1C, the charging is completed, and the charging system and the charging circuit are closed. The charging curve is shown in the figure below.
According to the different power, the charger adopts different control technology. The linear power supply is the main scheme for low power, and the switching power supply is the main scheme for high power. Charger technology has been quite mature, charger performance and efficiency are basically able to reach a relatively good level. There are many related manufacturers. The main technologies involved in the charger are mainly power supply technology and battery technology. The related manufacturers have also done power supply manufacturing before.
