4 Tips to Choose the Right Solar Battery for Your Photovoltaic System

Author name

Choosing the right solar battery for your home can be a tad difficult at times. There are a variety of batteries available to choose from but with the right pointers you will be able to find the right one for your home. 

In this blog, we are listing a few factors based on which you can choose the right solar battery which are as follows:

1.Type of solar battery:

Spend some time researching the types of solar battery available. Nickel metal hydride (NiMH), nickel cadmium (NiCd), lithium ion (Li-ion) and lead-acid batteries are the main categories of batteries reigning in the market.

Out of all these, lithium-ion batteries are highly efficient ones but at the same time are costly too. Lead acid batteries are time tested with reliable performance and are also affordable too. Always go for batteries from reliable battery manufacturers.  Select is a leading Solar Battery Manufacturers in Rajasthan that provides high quality solar batteries.

2.Your home’s requirements

The solar battery you choose should be able to fulfill all the power requirements of your home. It also depends on your home’s location and the amount of sunlight your home receives. Depending on these factors, decide on the type of solar battery you need.

The total capacity of your battery system will be determined by the total energy your home requires and that which needs to be stored. Keep a margin of 50% for unseen situations.

3.Match the requirement solar battery to the solar panel voltage 

The solar battery you choose should always be compatible with the solar panels used. Based on the voltage demands of the solar panel, choose the appropriate solar batteries. As the solar panels generate direct current (DC) power, they will always need solar batteries with a certain voltage usually around 12 or 24 volts.

Although a single solar battery is sufficient for two solar panels in a photovoltaic system, if you are installing three or four solar panels, it would be preferable to install two separate solar batteries rather than just one large-capacity unit as this will help prevent overloading and give each panel its own dedicated energy storage.

4.Charge-Discharge Cycles of battery 

The life of a battery can be measured with its discharge cycles. The percentage of electrical energy that can be extracted from a battery relative to its overall capacity is known as the depth of discharge. The battery's depth of discharge will be 75% (8 kWh/ 10 kWh), for instance, if the manufacturer's recommended depth of discharge is 10 kWh and you only drain 8 kWh.

Manufacturers of batteries specify a specified DoD limit for their batteries. The figure provided is the maximum discharge that a battery can produce without degrading its performance in the future. For instance, the DoD of the majority of lead-acid batteries is 50%. In this scenario, if you want your battery to live longer, it would not be advised to deplete the battery by more than 50% of its capacity. This warranty is valid as long as you follow the manufacturer's recommended usage guidelines.
