A solar street light is a lighting device that uses solar energy to generate electricity, which converts solar energy into electricity through solar panels, and then stores it in batteries for night lighting. For a 6m 30w solar street light, the size of the battery is very important, it directly affects the lighting time and performance of the street light.
Generally speaking, the larger the battery capacity of a solar street light, the more electricity it stores and the longer it will illuminate. For 6m 30w solar street lights, generally choose a battery with a battery capacity of about 12v 100ah. Such a battery capacity can meet the needs of night lighting, ensuring that the street lights can last for 8-10 hours.
In addition, the type of battery will also have an impact on the performance of solar street lights. At present, the common types of solar street light batteries on the market are lead-acid batteries, lithium batteries and lithium titanate batteries. Lead-acid batteries are traditional solar street light batteries with a lower cost but a relatively short lifespan. Lithium batteries and lithium titanate batteries have higher energy density and longer life, but they are also relatively high.
In addition to the battery capacity and type, the battery of the solar street light also needs to have some special properties to adapt to the needs of the outdoor environment. First of all, the battery needs to have a high charge-discharge efficiency to ensure that the solar panels can fully use the solar energy for charging and storing the electrical energy efficiently. Secondly, the battery needs to have a high cycle life and be able to withstand long-term charging and discharging cycles to ensure the long-term stable operation of solar street lights. In addition, the battery also needs to have good temperature resistance and be able to work normally in high or low temperature environments.
In short, for a 6m 30W solar street light, the size of the battery should be around 12V 100Ah, and it needs to have high charge and discharge efficiency, cycle life and temperature resistance. Such a battery can meet the needs of night lighting and ensure that the street lights can work stably and efficiently.
