4 kinds of solar street lamp commonly used batteries, which battery is the best

The batteries commonly used in solar street lights are lead-acid batteries, nickel-metal hydride batteries, lithium batteries and sodium-nickel batteries. So, which battery is the best?

First of all, lead-acid batteries are one of the most widely used solar street light batteries at present. It has the advantages of low cost, high reliability, and large capacity, but its energy density is low, the charging and discharging efficiency is not high, and the life is relatively short, which requires regular maintenance and replacement.

Secondly, nickel-metal hydride battery is an environmentally friendly battery, which has the advantages of high energy density, long life, and high charging and discharging efficiency. It has a long cycle life and can withstand high and low temperature environments, but it is more costly, bulky, and requires a larger installation space.

Again, lithium battery is a high-performance solar street light battery. It has the advantages of high energy density, light weight, long life, and high charging and discharging efficiency. Lithium batteries have a long cycle life and are able to operate over a wide temperature range, but they are expensive and require higher safety measures.

Finally, sodium-nickel battery is a new type of solar street light battery. It has the advantages of high energy density, long life, and high charging and discharging efficiency. Sodium-nickel batteries have a long cycle life and are able to operate in extreme temperature environments, but they are expensive and require large installation space.

To sum up, each solar street light battery has its advantages and disadvantages. According to the actual needs and budget, it is best to choose the most suitable battery type. If you pursue low cost and high reliability, lead-acid batteries are a good choice; If you pursue high performance and long life, lithium batteries and sodium-nickel batteries are better choices.

4 common solar street lamp batteries: lead-acid batteries, gel batteries, ternary lithium batteries, lithium iron phosphate batteries, the current ternary lithium and lithium iron phosphate are used more, one is small size, the transportation cost is relatively small, the wiring is also convenient, and the pollution of lead-acid batteries and gel batteries is greater.

Summary. Pro, gel battery: equivalent to the upgraded version of the lead-acid battery, it is maintenance-free, solves the frequent criticism of the maintenance of lead-acid battery, the internal colloidal electrolyte replaces the sulfuric acid electrolyte, in terms of power storage, discharge, safety performance and life have been improved, but sometimes even catch up with the ternary lithium-ion battery.

The gel battery can be used in the temperature range of -40 65, and the low temperature performance is relatively good, and it can be used in the northern alpine region. It has good seismic performance and can be used safely in various harsh conditions. The service life is twice or more than that of ordinary lead-acid batteries.

Which battery is good for solar street lights.

Hello dear <>, I'm glad to answer for you. Solar street light gel battery is good.

Pro, gel battery: equivalent to the upgraded version of the lead-acid battery, it is maintenance-free, solves the frequent criticism of the maintenance of lead-acid battery, the internal colloidal electrolyte replaces the sulfuric acid electrolyte, in terms of power storage, discharge, safety performance and life have been improved, but sometimes even catch up with the ternary lithium-ion battery. The gel battery can be used in the temperature range of -40 65, and the low temperature performance is relatively good, and it can be used in the northern alpine region.

It has good seismic performance and can be used safely in various harsh conditions. The service life is twice or more than that of ordinary lead-acid batteries.

Pro, solar street lamp battery is an important accessory in solar street lamp, currently used in lead-acid battery, gel battery, ternary lithium-ion battery and lithium iron phosphate battery. The one that is easier to use and has a high safety factor is the gel battery.

NiMH battery: high rate charge and discharge performance, no pollution, green and environmentally friendly battery; The use of small systems in the canopy is worth advocating.

Solar street lamp is powered by crystalline silicon solar cells, maintenance-free valve-regulated sealed batteries (gel batteries) to store electric energy, ultra-bright LED lamps as light sources, and controlled by intelligent charge and discharge controllers, which are used to replace traditional public electric lighting.

Solar energy is an inexhaustible, clean, pollution-free and renewable green and environmentally friendly energy. Using solar power generation, incomparable cleanliness, high safety, relative breadth and sufficiency of energy, long life and maintenance-free and other advantages that other conventional energy sources do not have, photovoltaic energy is considered to be the most important new energy in the 21st century.

Solar street lamps do not need to lay cables, AC power supply, and electricity bills; DC power supply and control; It has the advantages of good stability, long life, high luminous efficiency, easy installation and maintenance, high safety performance, energy saving and environmental protection, economy and practicality.

It can be widely used in the city's main and secondary roads, residential areas, factories, tourist attractions, parking lots and other places. Product components lamp pole structure: steel lamp pole and bracket, surface spray treatment, battery panel connection using special anti-theft stainless steel screws.

Dear, I am happy to serve you, , the following is the answer for you: solar lights with charger If you want to charge with the charger, you need to disassemble it, take out the battery, and choose the right charger according to the nominal voltage of the battery inside. (If it is a lithium battery, it can be charged with a charger of a lithium battery, if it is a 6V lead-acid battery, it can be charged with a 6V lead-acid battery charger, and batteries with different voltages and different capacities can be charged with chargers with different voltages and currents, which need to be reasonably matched).

1. The voltage of the battery of the battery multiplied by AH is the WH, such as filial piety and then divide the WH by the power of the bulb W is the time to light up.

2. Battery capacity: 50W * 8 hours * 3 days = 1200Wh, if you use 12V battery capacity to choose 1200Wh 12V = 100Ah, if you use 24V battery capacity to choose 1200Wh 24V = 50Ah, and so on.

3. The solar panel has a certain loss of battery charging, the actual utilization rate is only 70%-90%, calculated according to the 80% loss, with a 50W light source, the light is 8 hours a day, then the light can be lit up for two nights and needs to use 50W * 2 80% = 125W battery panel, if the light can be lit for three nights in a day, it needs to use 50W * 3 80% = 187W battery return board, and so on.
