As more individuals switch from traditional illumination to solar lighting, battery lights have become all the rage. Solar battery lights are the solar lighting system’s most critical component. Thus, you should educate yourself on the technicalities involved before buying one. Given the large range of battery types and capacities available on the market, buyers may have trouble settling on the best option. With that in mind, this comprehensive guide will provide you with all the information you need to make an informed selection of battery lights.
How do solar battery lights work?
Lighting-emitting diodes (LEDs), photovoltaic cells, rechargeable batteries, and charge controllers are the four primary components of solar battery lights. Batteries have two electrodes—an anode and a cathode—housed inside a plastic or metal case. The photovoltaic process describes the chemical reactions that occur at these electrodes when light hits the solar cells. All solar lights use photovoltaic cells, which convert sunlight into electricity. When placed in direct sunlight, electrons with a negative charge migrate to the anode, while those with a positive charge head to the cathode. This generates a current that is collected by batteries.
The battery light is designed to store energy for later use. When there is no sunlight available to power the solar lights at night, the energy stored in the batteries is used. The majority of solar light batteries are constructed utilizing a high deep discharging performance gel electrolyte technology. The use of nickel-metal halide, nickel-cadmium, and lithium, in addition to lead-acid, is commonplace among battery makers. Moreover, the battery management system helps to manage the rechargeable battery. So, it is important to use a battery management system to use a solar battery light efficiently.
