Solar energy systems typically comprise of solar batteries and panels, mounting equipment, and a performance monitoring system. The panels gather the sun’s energy, which is processed and sent to an inverter, from which you can use electricity in your house, business, or industrial setting. Because most homes are connected to the grid, homeowners use these systems for backup often. Many people, on the other hand, are looking for a way to replace their utility supply. One of the most popular reasons individuals switch to solar is to avoid higher electricity expenses.
What is a Solar Battery?
A solar battery simply stores the energy generated by your energy system’s solar panels. They may feature an integrated energy conversion and performance monitor in their inverter. In addition, the storage capacity of various types of solar batteries is proportional to their capacity.
Simply put, the solar battery is the part of your solar panel system that stores the energy that the panels provide to your home. When the solar panel isn’t producing any electricity, its battery will release the energy it has saved for you to utilise.
If you stay totally off the grid, these batteries can supply homes with 100 percent self-sufficiency as long as the solar panels adequately charge the batteries.
Types of Solar Batteries
Solar batteries are gaining more popularity as a source of power at periods when utility bills are becoming a cause of concern for most people. You can use this developing yet sturdy equipment in your house or business, depending on your purpose and desired outcome. The following are the types of solar batteries available in the market:
- Lead-Acid Batteries: Lead-acid batteries have been used in off-grid energy systems for several years, since they are usually deep-cycle and low-cost. Lead-acid batteries are known for their high power and discharge current, but they are also known for their low energy. They require a lengthy time to fully charge – up to 14 hours.
- Lithium-Ion Batteries: Lithium-ion batteries are becoming increasingly common for solar systems all around the world. This type of solar battery is low-maintenance, has a high specific energy, and has a long lifespan.
How to Choose the Right Solar Battery?
When it comes to deciding which solar battery to utilise, you’ll need to take into account a few unique aspects to make a more informed decision. Some things to think about are:
The capacity of a solar battery simply refers to its ability to store electrical energy. Due to their heavier weight, lithium batteries have a higher capacity than all other types of lead-acid batteries.
- The Depth of Discharge (DoD)
The DoD of a solar battery is the portion of its capacity that may be used, and a DoD of at least 40% is suggested for maximum battery performance. Lead batteries typically have a DoD of 50%, whereas nickel-cadmium batteries have a DoD of 15%. A battery’s lifespan will be shortened if it reaches this point before being recharged. Solar batteries made of lithium-ion and sodium nickel chloride, on the other hand, have an 80 percent DoD, implying a higher useable capacity.
- Life and Warranty of Solar Batteries
Battery life is the best measure of a solar battery’s ability to maintain capacity when determining which one to use in your system. A charge cycle is essentially the time it takes for a solar battery to fully charge and discharge, and it is the most important metric for determining the battery’s lifespan. The frequency of usage will determine how many charge cycles the solar battery goes through. Even for the same type of solar battery, this characteristic varies and is influenced by the DoD of the battery.
- Usage Pattern
You must evaluate the pattern of power outages in your area when selecting a battery for alone to predict how many times it will be needed during the year. If it will not be used heavily, a low-maintenance battery, such as a sealed lead-acid solar battery, can be the smarter choice. The lithium-ion type is suitable for powering industrial sites where intensive use is expected on a regular basis.
One thing to keep in mind when you are looking for a suitable solar battery is the brand that you choose. Luminous is one of the most trusted brands in India when it comes to solar batteries. They provide a wide range of choices, backed by a pan-India service network to help you discover the right battery for your house.
