Solar rechargeable batteries are a triumph of science and harness the power of solar energy to store electrical energy.
Solar batteries give a huge advantage in the long run because after the initial installment, the user can generate an unlimited amount of electricity free of cost.
Moreover, it serves as a backup in case of any power cuts and helps to preserve our conventional sources of energy like fossil fuels.
This technology is also environment friendly because it harnesses power from solar energy, which is a non-conventional, unlimited source of energy.
There are many types of solar rechargeable batteries which include: lead-acid battery, lithium-ion battery, flow battery, and sodium nickel chloride battery, which all have the same basic principle of working with different updates in each type.
The more the capacity of the battery, the more it can charge in one go, and capacity and power ratings depend on different properties, for example, power density.
Solar batteries need maintenance similar to normal electrochemical batteries, and battery terminals need to be regularly cleaned with distilled water, ensuring the connections are tight to allow gassing and boiling.

Final Thoughts
Solar batteries absorb solar energy, which is a non-conventional source of energy and is unlimited; therefore, solar batteries are a form of green technology doing no harm to nature and helping in conserving our conventional sources like fossil fuels.
Solar batteries do not require maintenance and emit no hazardous gases during charging and there is no leakage of liquid.
They are also a one-time investment and provide free energy for a long time, making them a good alternative to conventional disposable batteries.
Even though AC power is generated from solar energy, which is finally stored in these batteries as DC power, solar batteries don’t need to be connected to a solar system to store charge.
This makes these batteries very useful in the situation of a power cut.
Solar batteries can work in any weather, even a cloudy winter’s day.
And though the efficiency might decrease by 10%, the overall working of the battery remains intact; nevertheless, these batteries might lose some efficiency in case of extremely hot temperatures.
In solar batteries, there is no noise generation during charging or fuel requirements, which make them a cheaper source of energy.
Solar batteries work on a wide range of temperatures, even on cloudy days.
