Why Self-contained Solar Lights Are the Best Lighting Solution for Parks and Recreation Areas?

/于 /由

The purpose of parks and recreation is to provide a safe and healthy environment for the people of the community, to keep the parks open during nights there is a need of illuminating it with lights and a self-contained solar lighting system offers the best solution to that.

"(《世界人权宣言》) self-contained and self-sufficient solar lighting solutions are ideal for general illumination in the city parks and recreations areas, as solar lights can be utilized anywhere light is needed, without the restriction of where power and how power is available, the possibilities of ensuring proper and renewable lighting to all areas are limitless!

solar lighting systems are a low-maintenance way to improve safety and visibility.

Below are some great ways a self-contained Solar Lights solution can fulfill the power needs.

Natural Parks:

The purpose of the natural parks is to give a real and natural feel to the observer. And to make it safe for the tourists, lighting the park is the utmost priority of the management. Most natural parks like to feature the surrounding areas without minimum disruption, so developing a traditional solution of lighting can cause disruption in the form of trenching and wiring. This would disturb the area greatly and can cause damage to the inhabitants. Another problem with these natural parks is that they are often at remote locations far away from grid stations. So instead of relying on conventional lighting, a solar street lighting system is a great option without disturbing the environment. The only thing to consider while installing this system is to avoid shaded areas as they will prevent the sunlight falling on the solar panels.

With the aim to conserve energy and reduce carbon footprints, countries have started to invest in this field. The increase in energy demand and continual rise in the cost of electricity has prompted a number of governments to take serious actions in replacing old lighting systems with 太阳能照明.

Since solar relies on an unlimited source of energy, governments are trying to implement the use of solar panels as an energy source in suburban and rural areas for lighting the streetlights.太阳能路灯市场

According to analysts, the global 太阳能路灯市场 will grow steadily, and by 2023 it would have grown by 21%. The growing demand for clean and renewable energy, ease of setting it up, low cost of maintenance during its operation, are acting as strong drivers for the growth of solar street lighting market.

Solar energy being dependent solely on sunlight plays an important role in reducing environmental pollution and has a bright prospect of applications.

Market Analysis of Solar Lighting

Solar streetlights are raised light sources which are powered by photovoltaic panels that are generally mounted on the lighting structures. The batteries are charged by photovoltaic panels which then provide power to LED lamps.

In 2012, the South was considered the largest revenue market with a market share of 32.46% in 2012 and 34.42% in 2017, an increase of 1.96%.  In 2016, Northeast and West were ranked as the second-largest market with a market share of 22.33% in 2016.

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.

Asia-Pacific is currently the largest region in the 太阳能路灯市场, and this situation will continue until 2030.

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.

What is the Solar Energy of Solar Panel?

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.

solar panel manufacturer

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.

太阳能电池板 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.

它表示充放电时使用的电流大小。它通常以电池标称容量的倍数来计算，一般称为 "几 C"。

对于容量为 1500mah 的电池，规定的放电电流为 1c = 1500mah。如果以 2c 放电，则意味着以 3000mA 的电流放电。以 0.1c 充放电则表示以 150mA 电流充放电。

  1. 电压（OCV：开路电压）

电池电压一般指锂电池的标称电压（也称额定电压）。普通锂电池的标称电压一般为 3.7V，我们也称其为电压平台 3.7V。我们所说的电压一般是指电池的开路电压。

当电池容量为 20-80% 时，电压集中在 3.7V 左右（3.6-3.9v），当容量过高或过低时，电压变化很大。

  1. 能源/电力

当电池按照一定标准放电时，电池可放出的能量（E）为 Wh（瓦特小时）或 kWh（千瓦时），1kwh = 1 千瓦时。

物理书中有一个基本概念：e = u * I * t，也等于电池电压乘以电池容量。

功率公式为 p = u * I = E / T，表示单位时间内可释放的能量。单位是 w（瓦）或 kW（千瓦）。

对于容量为 1500mah 的电池，标称电压一般为 3.7V，因此相应的能量为 5.55wh。

  1. 阻力

由于存在一定的内阻，充放电不能等同于理想电源。内阻会消耗能量。内阻越小越好。

电池内阻的单位是毫欧（m Ω）。

一般来说，电池的内阻包括欧姆内阻和极化内阻。内阻的大小受电池材料、制造工艺和结构的影响。

  1. 周期寿命

电池充放电一次称为一个循环，循环寿命是衡量电池寿命性能的重要指标。

根据 IEC 标准，手机锂电池应在 0.2C 时放电至 3.0V，在 1C 时充电至 4.2V。循环 500 次后，电池容量应保持在初始容量的 60% 以上。换言之，锂电池的循环寿命为 500 次。

根据国家标准，循环 300 次后，容量应保持在初始容量的 70% 左右。

如果电池容量低于初始容量的 60%，则一般视为报废。

  1. DOD：排放深度

其定义是电池释放的额定容量的百分比。

一般来说，放电深度越深，电池寿命越短。

  1. 截止电压

终止电压分为充电终止电压和放电终止电压，即电池不能继续充电或放电的电压。如果电池在终止电压下继续充电或放电，电池寿命将受到很大影响。

锂电池的充放电终止电压分别为 4.2V 和 3.0V。

严禁对超过终止电压的锂电池充电或放电。

  1. 自放电

它指的是在下列情况下容量的下降率太阳能电池以单位时间内容量减少的百分比表示。

一般锂电池的自放电率为 2% ~ 9% /月。

  1.   SOC（充电状态）

指电池剩余电量与可放电总电量的百分比，0 ~ 100%。反映电池剩余电量。

 

（5）锂离子电池命名规则

不同 电池 制造商 虽然命名规则各不相同，但我们都遵循通用电池的统一标准。根据电池的名称可以知道电池的大小

根据 IEC61960 标准，圆柱形和方形电池的规则如下：

  1. 圆柱形电池，3 个字母后有 5 个数字、

三个字母中，第一个字母表示负极材料，I 表示内置锂离子，L 表示锂金属或锂合金电极。第二个字母表示正极材料，C 表示钴，n 表示镍，m 表示锰，V 表示钒。第三个字母 R 代表圆柱体。5 位数字中，前两位数字代表直径，后三位数字代表高度，单位均为毫米。

  1. 方形电池，3 个字母后 6 个数字、

三个字母。前两个字母的含义与圆柱体相同。最后一个字母是 p，意思是正方形。

共有六位数字，前两位表示厚度，中间表示宽度，后两位表示高度（长度），单位也是毫米。

例如，ICR 18650 是一种通用的 18650 圆柱形电池，直径为 18 毫米，高度为 65 毫米；

ICP 053353 是一款方形电池，厚度为 5 毫米，宽度为 33 毫米，高度（长度）为 53 毫米。

（6）锂离子电池技术

不同电池和不同制造商的工艺流程存在一些差异，详细的工艺流程会非常复杂。基本工艺流程、电池制造工艺流程和电池组制造工艺流程如下。

电芯的生产过程主要包括极片制造、电芯制造、电池组装、注液、化成、分离等工序。

从配料到卷绕，正负电极在不同车间同时制作。正负电极制作完成后，后续工序一起完成。中间会穿插不同的质量检测 QA 环节。

（7）锂离子电池的分组和串并联

在不同的领域，对蓄电池的要求也不尽相同。系统对电压、容量、内阻等都有一些特殊要求，往往单个蓄电池无法满足要求，需要串并联起来向外供电。

串联和并联电池的性能由最差电池的性能决定，这通常被称为 "木桶原理"。因此，电池分组最重要的一点是电池性能参数的一致性。

例如，笔记本电脑、电动自行车、电动汽车、储能系统等都需要考虑电池的串联和并联，以组成电池组。

笔记本电池电压一般为 11.1V 或 14.8V，以 18650 电池为主，所以一般为 2 串 3 并或 2 串 4 并。

苹果 iPad 是三块并联的聚合物电池，容量约为 25wh。

电动自行车和电动摩托车系统一般为 24V、36V、48V、60V 和 72V 系统。具体组别条件见下表（s 表示串联）。

纯电动汽车和混合动力电动汽车（EV/PHEV）的电压较高，约为 250 ~ 500V，串联后最高电压将超过 150 节。

此外，电池串并联分组需要考虑很多因素，如电池电压平台的一致性、电池容量的一致性、电池内阻的一致性等。

串并联后电池参数的一致性对电池的性能和寿命有很大影响。

电池组电压锰酸锂/三元锂磷酸铁锂
12V4S4S
18V5S6S
24V7S8S
36V10S12S
48V13S15S/16S
60V16S19S
64V18S20S
72V20S23S

 8）各种动力电池的比较

动力电池主要考虑其用途，主要用于电动汽车、电动自行车、电动工具等。

动力电池不同于普通电池，它有一些特殊的特性

  1. 电池的串联和并联
  2. 电池容量更大
  3. 电池放电率高（混合动力和电动工具）
  4. 电池的安全要求更高
  5. 电池工作温度范围广
  6. 电池使用寿命长，一般为 5-10 年

由于动力电池的特殊性，其工艺和材料也存在一些差异。根据正极材料的情况，主要分为锰酸锂（LiMn2O4）、三元锂（linixcoymnzo2）、磷酸铁锂（LiFePO4）等，其电压平台、能量密度、价格、安全性等都有一定的差异。详见下表中的比较：

(钴酸锂由于稳定性差、价格昂贵，很少用作动力电池，下表对其进行了列举和比较）

8环保钴含镍和钴/   /
9安全贫穷一般情况良好优秀
10应用小型电池小型电池、小型动力电池动力电池动力电池，超大容量电源

（9）锂电池型号

就电气特性而言，电池的内阻并不完全等同于电阻。详情请参考国外的 PNGV 等效电路模型。如下图所示。

电池的内阻主要由欧姆电阻 R0 和极化电阻 R1 组成，其中 C1 是极化电容。

电池内阻测量在业内主要有两种测试方法。直流放电法和交流注入法，这两种方法无法用普通的电阻测量方法进行测量，只能用专用的内阻测量仪进行测量。

电池的内阻是反映电池性能和寿命的一个重要参数。当电池的循环寿命临近时，电池的内阻会急剧增加。循环次数与内阻之间的关系如下图所示。

10）锂离子电池的电气特性和主要参数

  1. 电池的充放电曲线

锂电池的充放电曲线是指电池容量与开路电压之间的关系曲线。根据放电曲线，可以大致估算出电池的功率，如下图所示。

锂电池的充放电曲线不仅与充放电电流有关，还与温度有关。如下图所示。

  1. 电池的主要参数

由于自身特性，锂电池不能过充、过放、过流或过热。因此，考虑到安全性和电池寿命，应适当保护电池。有几个经常遇到的参数，现并列列出。不同制造商生产的电池电压差别不大。不过，工作温度不同、放电率不同或制造商不同的蓄电池之间会有一些差异。

比较项目锰酸锂/三元锂磷酸铁锂
电压3.7V/3.6V3.2V
截止充电电压4.2V3.6V
放电截止电压3.0V2.0V
运行温度-20~60℃-10~65℃
最大放电率3~10C3~10C

11）锂离子电池保护和管理要求及系统

由于锂电池的特性，有必要添加电池保护板（PCM）或电池管理系统（BMS）。没有保护板或管理系统的电池是禁止使用的，而且会存在巨大的安全隐患。安全始终是电池系统的第一要务。

如果电池没有得到很好的保护或管理，可能会有寿命缩短、损坏或爆炸的风险。

PCM（电源电路模块）主要用于手机和笔记本电脑等消费类产品。

电池管理系统（BMS）主要用于动力电池，如电动汽车、电动自行车、储能等大型系统。

PCM 的主要功能包括 OVP、UVP、OTP、OCP 等。一旦出现任何异常，系统将自动切断，以确保系统安全。

电池保护系统技术已经非常成熟，相关的电路板工厂很多，主要集中在华南地区。还有专门的 IC 厂商提供专门的锂电池保护芯片。这一块比较成熟，国内也有很多成熟的保护 IC 芯片。

除了保护系统的基本保护功能外，电池管理系统（BMS）的主要功能还包括电池电压、温度和电流测量、能量平衡、SOC 计算和显示、异常报警、充放电管理、通信等。有些 BMS 系统还集成了热量管理、电池加热、电池健康状态（soh）分析、绝缘电阻测量等功能。

介绍和分析 BMS 功能：

  1. 电池保护与 PCM 类似，包括过充、过放、过热、过流和短路保护。与普通锂锰电池和三元锂电池一样，一旦任何电池的电压超过 4.2V，或任何电池的电压低于 3.0V，系统将自动切断充电或放电回路。如果电池温度超过电池的工作温度或电流大于电池的放电电流，系统将自动切断电流通路，以确保电池和系统的安全。
  2. 整个电池组工作一段时间后，能量平衡会出现很大差异，这可能是由于多个电池串联、电池本身不一致、工作温度不一致或其他原因造成的。能量平衡就是为了弥补单个电池之间的差异，进行一些主动或被动的充放电管理，以确保电池的一致性，延长电池寿命。

业内有两种方法：被动均衡和主动均衡。被动均衡主要是平衡电阻消耗的电量。主动均衡主要是通过电容、电感或变压器将功率大的电池的电量转移到功率小的电池上。被动均衡和主动均衡的比较如下表所示。

由于主动平衡系统相对复杂，成本相对较高，因此主流仍是被动平衡。

比较项目被动平衡主动平衡
平衡模式阻力消耗感应等效转移
平衡效率低高
计划成熟度发育成熟更成熟
系统复杂性低高
系统成本低高
  1. SOC 计算、电池电量计算是 BMS 非常重要的一部分，许多系统都需要更准确地了解剩余电量。由于技术的发展，SOC 的计算方法有很多。如果精度要求不高，可以根据电池电压判断剩余电量。主要且准确的方法有电流积分法（也称啊法）、q = ∫ I DT、内阻法、神经网络法、卡尔曼滤波法等。目前业界主流的仍是电流积分法。
  2. 通信。不同的系统对通信接口有不同的要求。主流的通信接口有 SPI、I2C、can、RS485 等。汽车和储能系统主要使用 can 和 RS485。

由于竞争不充分和 BMS 系统的复杂性，系统制造商相对较少。相关的芯片制造商主要是欧美厂商，中国也有几家大公司。未来机会很多。

我希望能通过电子邮件与您就 BMS 的技术、产品和制造商进行交流。

（12）锂离子电池充电要求和系统

锂电池的主流充电方式是恒流恒压（CC / CV）：恒流-恒压。先对恒流充电，达到一定电位后再对恒压充电。好的充电器还能根据电池电压状态进行涓流充电。有些系统还会在后面添加脉冲充电模式，并根据时间设置充电结束时间。

普通充电器集成了限流、限压、过压保护、过流保护、过热保护和防反接等功能。具体充电系统如下图所示。

此外，充电器充电通常与 PCM 或 BMS 相结合，以便在恒压充电阶段进行能量平衡。

对于普通钴酸锂电池，如果电池电压低于 3.0V，充电器将启动涓流充电（约 0.1C），以避免损坏电池。当蓄电池电压充至 3.0V 时，将转为恒流充电（约 1C，电流取决于系统）。当蓄电池电压达到 4.1V 时，检测到蓄电池电压转换为恒压充电。当电池电流降至约 0.1C 时，充电完成，充电系统和充电电路关闭。充电曲线如下图所示。

根据功率的不同，充电器采用了不同的控制技术。小功率以线性电源为主，大功率以开关电源为主。充电器的技术已经相当成熟，充电器的性能和效率基本上都能达到比较好的水平。相关的生产厂家也很多。充电器涉及的主要技术主要是电源技术和电池技术。相关厂家以前也做过电源制造。
