Solar Batteries Facts

The batteries that are powered by the solar energy are way different from the ordinary ones.

• The most important criterion that determines the value and efficiency of a battery is its cycle. In a battery, a cycle can be described as the process of discharge and recharge and the amount of discharge that occurs in a battery is termed as the depth of discharge. Based on this cycle, batteries can be divided into deep cycle and shallow cycle batteries. The batteries that are used inside solar appliances are deep-cycle batteries.
• A deep-cycle battery can be described as one where 80% of the power is discharged and then gets recharged.
• The basic objective of these batteries is to store the electricity generated using the solar energy and provides power to the appliance whenever required for a prolonged duration of time.
• These deep-cycle batteries are different from the customary ones in the sense that they release the electrical power in a slow and steady manner and maintain the output for long durations. This is because sun remains for only a certain period of the day. In case of traditional batteries such as those used in the cars, the power output is sudden, very high and short-term so as to keep the engine running.
• With deep-cycle batteries, one has to no longer worry about power supply during nights or on a rainy or gloomy day when there is very less or absolutely no sunlight.
• Also, maintenance of deep-cycle batteries is neither difficult nor time-consuming.
