What kind of batteries are used in solar street lights?
Lithium batteries are the most common types of solar rechargeable batteries for solar LED street lighting. They sustain almost 4 times discharge, apparently high for batteries. They can also live up to 5 times longer than lead-acid batteries.
Generally, there are 4 main types of batteries for large capacity solar lights For smaller solar lights like garden lights, yard lights, bollard lights, fairy lights, two battery types are available.
Best Rechargeable Batteries for Solar Street Lights
Solar street light batteries are often deep cycle batteries. These types of batteries are rechargeable and sustainable, which make them widely used in the renewable energy sector.
Deep cycle batteries have cycle times 2 to 3 times higher than automotive batteries and they can extend for up to 3000 cycle times.
Valve Regulated Lead-acid batteries are the oldest and the most common batteries for solar street lighting. They are also the cheapest in price. You may find lead-acid batteries common in cars.
Generally, they are heavier than other battery types and have a shorter life cycle. That is why most manufacturers prefer Lithium batteries.
Once in a while, they have to be replenished in a distilled water solution to prolong its life span. Lead-acid batteries can be inefficient in terms of charge and discharge cycles.
The upside to this type of battery is that they are inexpensive and reliable only if you follow its charging and discharging cycle properly. For solar street lights, the usual price of VRLA battery 150Ah is around $150 to $400 depending on the battery brand.
