Solar street lights are very convenient since they provide light during night hours without requiring access to the electrical grid. These lighting systems include a solar module and a battery, allowing the equipment to generate power during the day, store it at the battery, and use it during night hours.
It is always important to pick the right battery for each solar street light since .
There are many solar battery technologies available for solar street lights.
Li-ion (NMC) batteries and lithium Ferro Phosphate (LFP) batteries are commonly used in solar street lights.
Lithium Iron Phosphate (LiFePO4) batteries are another great lithium battery technology. These batteries have high energy density and can be discharged to an 80% DOD while delivering around 2,500 cycles.
LiFePO4 batteries are manufactured with graphite anodes and lithium iron phosphate cathodes, immersed in a lithium salt electrolyte. This is the preferred lithium technology for solar street lights since provides a maintenance-free option with high energy density.
