正确选择户外太阳能灯的三大因素

Users or consumers often find there are lots of key factors in selecting outdoor solar lights,hence, we figure out top 3 factors here.

Top 3 Factors to Choose Outdoor Solar Lights

We all understand that we shall make a good quality product for our users across the world. No matter they are coming from Malaysia, Saudi, UAE, Sweden, Brazil, Australia, South Africa, Namibia, Uganda, or elsewhere, they will all be treated with a high standard quality product. Mostly, the solar-powered street lights are all in one type in the market. All in one is actually three in one type. Three means three major parts for solar street lights, i.e.  solar panel, LED light, and battery. Therefore, I am recommending use to take a look at these top 3 factors before buying solar-powered street lights. Let’s begin.

 

1 – EFFICIENT SOLAR PANEL FOR OUTDOOR SOLAR LIGHTS

It took around two decades for photovoltaics (PV) or solar PV to become a mainstream electricity source from small scale applications. Price in the past could only be accepted by users like military and aerospace who don’t really care about the cost too much. Now, the price has dropped to a level that is affordable to civil users.

Solar panel energy has been developed for many years. Technically speaking, the product is mature enough. Usually, the high-efficiency solar cell will come with an MPPT controller for stable performance. The controller also takes care of light absorption in summer and winter.

As regards to the efficiency, monocrystalline solar panels are higher efficiencies and sleeker aesthetics than polycrystalline solar panels. Doubtlessly, polycrystalline panels are sold at a lower price.

Both monocrystalline and polycrystalline solar panels serve the same function in the solar PV system: they capture energy from the sun and turn it into electricity. The technology is so powerful that it can even work and provide lighting under weak light conditions. This is especially helpful in wintertime for high latitude areas like Sweden and Canada. Our customer in Sweden is continuously buying solar-powered street lights from us which is a great honor to us. It is sure that we have installed a special component unit for Sweden market which need complementary power in winter.

As mentioned, the solar panel industry has been developed for so many years. The solar panel itself is guaranteed with at least 20 years lifespan in most cases.

 

2 – OPTIMIZED LED LIGHTING SYSTEM

The top 3 factors for outdoor solar lights go number 2. LED chips are various and different chip vendors provide respective lighting solutions. Bridgelux, Cree, Lumileds, Nichia, OSRAM and Philips are common choices of solar lights factories who cherish their product quality and reputation.

For example, when we choose Bridgelux, we will take into consideration of LED power and lumen efficacy into consideration after comparison between brand and brand. Bridgelux has great performance regarding ESD protection. ESD protection devices (anti-static components) protect a circuit from Electrostatic discharge (ESD). The value of ESD for Bridgelux can be as high as 3000V. The product of the brand has high stability because it has a double electric shock structure and has 6 protective films on the surface. The factory is easier to operate in the downstream production process while the product yield is better controlled. At the same time, the light decay is less.

As a whole, other brands are also being picked for use when we produce a specific item since we need to consider the system output performance.

 

3 ENHANCED BATTERY UNIT EMPOWERS SYSTEM PERFORMANCE

Lithium-ion-Battery
The battery unit is outsourced from battery vendor. If an outdoor solar light manufacturer wants to use a low-cost component, then a lead-acid battery is possibly being used. The lead-acid battery has one of the lowest power-to-weight & power-to-volume battery designs in existence, making it big and heavy for the total amount of power it can put out.

In past years, quite many off-grid energy systems are equipped with lead-acid batteries. Now, most of them are defunct or replaced. People are turning to the solution of LiFePO4 lithium-ion battery.

LiFePo4 battery pack with 2000 times long life circles which is 3 times longer than Lead-Acid battery. When you browsing on the internet shopping site for outdoor solar lights, some vendors will indicate the warranty time of the product. Some warranties are so short that you will question yourself for what circumstance a customer will buy and question sellers for what kind of product they are selling at such a low price.

Moreover, please be aware of some suppliers who are using second-hand batteries taking down from electric vehicles.

Above the top 3 key factors are of fundamental importance as they are the main parts of outdoor solar lights.

We are carefully selecting our battery vendor and use the 锂电池 product that can support a longer lifespan which is beneficial to both customers and us.

让太阳能 LED 灯寿命更长的 5 个小窍门

中国太阳能电池制造商

磷酸铁锂电池(LiFePO4 电池)或三元锂电池?

如何选择太阳能路灯蓄电池?

众所周知,越来越多的人开始购买 一体化太阳能路灯太阳能路灯质量的关键点之一是太阳能路灯蓄电池的选择。通常,我们使用三元锂电池或锂离子电池。 磷酸铁锂电池.让我们来比较一下两者的区别。

LUXMAN - 太阳能电池制造商

首先,我们为什么要使用锂电池?

锂电池 (锂离子电池):锂电池的优点是重量轻,因此被广泛使用。, 容量大,无记忆效应。锂电池的能量密度非常高,其容量是同等重量镍氢电池的 1.5-2 倍(SYLVANIA 太阳能路灯采用镍氢电池)。(SYLVANIA 太阳能路灯采用的是镍氢电池)锂电池的自放电率也很低。此外,锂电池几乎没有 "记忆效应",也没有有毒物质,这也是其广泛应用的重要原因。

32700 电池

三元锂电池和 磷酸铁锂电池 是太阳能照明产品使用的两种主要锂电池。

三元锂电池与磷酸铁锂电池

I:磷酸铁锂电池和三元锂电池的材料体系不同。

二:磷酸铁锂电池是 3.2V 电压平台,循环寿命超过 2000 次充电。

三:三元锂电池是 3.7V 电压平台,循环寿命取决于不同厂家、不同型号、不同工艺,一般为 500-800 次充电循环。

四:磷酸铁锂电池具有更好的高温性能,而三元锂电池具有更好的低温性能。

五:磷酸铁锂太阳能路灯电池更安全。

对两种锂电池的进一步分析、

磷酸铁锂电池具有安全性高、高倍率充放电特性和循环寿命长的特点。 当充电条件为 1C 多次充电至 3.65V,然后恒压变为 0.02C,再以 1C 多次充电至 2.0V 截止电压放电,循环 1600 次后,电池容量为初始容量的 80%。磷酸铁锂电池还具有稳定的充放电特性和良好的快速充电特性。除了长寿命和出色的充放电性能外,磷酸铁锂电池的最大优势还在于其安全性。磷酸铁锂电池的化学性质稳定,高温稳定性好。磷酸铁锂电池在 700-800 C 时开始分解,在撞击、针刺、短路等情况下不会释放氧分子。不会产生剧烈燃烧,安全性能高

32700 节电池

磷酸铁锂电池的缺点是其性能受温度影响很大,特别是在低温环境下,放电容量和电容量都会大大降低。此外,磷酸铁锂还存在一些性能缺陷。电池能量密度低,仅电池重量能量密度就达到 120Wh/kg。如果计算包括电池管理系统、散热和其他组件在内的整个堆栈的能量密度,则会更低。材料制备成本和电池制造成本较高,电池成品率低,一致性差。每组成本高于三元锂电池

三元锂电池是指含有镍、钴和锰的过渡金属锂闰氧化物的锂电池。可表示为 LiMnxNiyCo1-x-yO2(0 < x < 0.5,0 < y < 0.5)。这种材料综合了氧化钴锂、氧化镍锂和锰酸锂的优点,形成了三种材料的三元协同效应,其综合性能优于任何单一组合化合物。重量能量密度可达 200Wh/kg

三元锂电池的安全性较差.三元锂电池的热稳定性很差。它们会在 250-300C 下分解。当遇到易燃电解质和碳材料时,会在某一点开始分解。产生的热量会进一步加剧正极的分解,并在极短的时间内爆燃。在车祸中,外力的冲击会损坏电池隔膜,从而导致短路,短路时产生的热量会使热温度迅速上升到 300 摄氏度以上,产生自燃的危险。因此,对于三元锂电池来说,电池管理系统和散热系统非常重要。

从上面的太阳能路灯电池知识中,你可以知道购买的路灯是优质版还是劣质版。

如果您购买的一体化太阳能 LED 路灯只标有 "锂电池 "字样,您必须知道它使用的是磷酸铁锂电池还是其他锂电池。大多数情况下是三元锂电池。如果是三元锂电,就不要指望有五年的使用寿命保证。
