How Many Types Of Solar-Led Street Lights?
The solar street light system may be classified generally into three categories based on the battery installation sites.
1- Split solar street lamp
The typical split solar street light system (led street light with its own solar panel and battery) is a self-contained distributed energy system. The solar panels, batteries, light source, and other system components are completely self-contained. The storage battery is often buried in the ground or mounted on a street light pole.
The second form is integrated solar street lights, also known as solar street lights that are all-in-one. It incorporates all of the system's elements and components into a single light body, making installation very simple.
The third form is a variant of integrated street lighting known as All in two solar street lighting. This kind of street light incorporates the lithium battery and solar control inside the LED street lamp body, but also includes an external solar panel.
How many types of batteries for solar street lighting systems?
In accordance with the various kinds of solar led street light systems discussed above, the majority of manufacturers of solar led street light systems use the following four types of batteries.
1. Lead-Acid Battery
The lead-acid battery (VRLA) is a kind of battery in which the electrodes are mostly composed of lead and its oxides and the electrolyte is composed of sulfuric acid. Additionally, it is referred to as an AGM battery.
The voltage is generally steady, which is an advantage. Under the same capacity assumption, it is the least expensive of the four kinds of batteries;
Disadvantages: Because the specific energy is low, the volume is substantially bigger than with conventional batteries. Lead-acid batteries have a limited service life of around 300-500 deep cycles. Additionally, maintenance is performed on a more regular basis. However, because of its cost advantage, it continues to be extensively employed in the solar street light sector.
A single-cell lead-acid battery has a nominal voltage of 2.0V, can be discharged to 1.5V, and can be charged to 2.4V; in many applications, six single-cell lead-acid batteries are connected in series to create a lead-acid battery group with a nominal voltage of 12V, or to create 24V, 36V, 48V, and so on. The typical AGM battery 12V 24V series has a capacity of 35AH250AH. It is primarily intended for use with split solar street light systems.
2. GEL Battery
GEL batteries are a kind of lead-acid battery that is still under development. The procedure involves adding a gelling agent to sulfuric acid to convert it to a colloidal condition. It is comparable to an enhanced lead-acid battery. It is maintenance-free, which eliminates the complaint of lead-acid batteries requiring periodic maintenance.
The advantages include increased storage capacity, discharge capacity, and longevity. The cycle life is about double that of AGM batteries, which may reach 500-800 deep cycles. Simultaneously, the GEL battery can be utilized at temperatures ranging from -40°C to 65°C, and its resistance to extreme heat and cold is far greater than that of AGM batteries. It is safe to use in a variety of high- and low-temperature environments. Excellent seismic performance, making it ideal for long-distance shipping.
Disadvantages: The price is much greater than that of AGM batteries, and in some cases exceeds that of lithium-ion batteries.
The colloidal electrolyte is used in lieu of the sulfuric acid electrolyte contained therein. A single-cell lead-acid battery has a nominal voltage of 2.0V and is capable of discharge. When it reaches 1.5V, it may be charged to 2.4V; in the solar street light application, numerous single-cell lead-acid batteries are often linked in series to provide a nominal 12V, 24V, 36V, or 48V lead-acid battery for usage. The most often used GEL batteries for solar street lighting are 12V 24V series 35AH300AH. Additionally, it is primarily employed in split solar street light systems.
3. Ternary Lithium Battery
The term "ternary polymer lithium battery" refers to a lithium battery with a positive electrode made of lithium nickel cobalt manganate (Li (NiCoMn) O2) or lithium nickel cobalt aluminate. A single ternary lithium battery has a nominal voltage of 3.7V. 3.7V battery systems are often utilized in solar-led street light systems.
The advantages include a high specific energy density and rapid charging. Its deep cycle periods are around 800-1000 times that of a gel battery, its life is comparable to that of a gel battery, its operating temperature range is -30 to 55 Celsius, and its low-temperature resistance performance is excellent, making it ideal for usage in low-temperature locations. Due to its compact size, it is mostly utilized in integrated solar street lights or all-in-two solar street lights.
Disadvantages: Inadequate resilience to high temperatures. Internally, its structure is unstable. If the ternary lithium-ion battery was manufactured by an unqualified manufacturer, it may explode during the overcharging process or when exposed to a higher temperature environment.
Although this option is the cheapest among lithium batteries in terms of price and capacity, it is not suited for solar street light systems with large power output, such as 100W or more. If ternary lithium batteries are used in certain high-quality solar street lights, professional manufacturers will utilize 11.1V systems (3pcs 3.7V battery in series), which have a capacity at least three times that of 3.7V, but at a higher price.
4. Lithium Iron Phosphate Battery
Lithium iron phosphate batteries are a kind of lithium-ion battery that includes lithium iron phosphate (LiFePO4) on the positive electrode and carbon on the negative electrode. The single unit's rated voltage is 3.2V, while the charge cut-off voltage is 3.6V3.65V. On the market, solar street lights with lithium iron phosphate batteries are commonly classified as 3.2V systems, 6.4V systems, or 12.8V systems. 3.2V battery packs are often utilized due to their compact size and low cost. The 12.8V battery packs are mostly used for high-quality street lighting; they are solar batteries with a long life.
