What are the dimensions of a solar battery?


With the various solar batteries available in the market. You can get solar batteries of different size. The solar batteries varies from small, medium and large. The size of the batteries determine the capacity, and the voltage. 

In this article, we will look at the different sizes of solar batteries and how the size affect the functionality of this batteries. By the end of the article, you will be able to know what size of solar batteries you need for your home solar PV system.

What are the dimensions of a solar battery?

Solar batteries come in small, medium and large batteries. The size of the battery will determine the price, capacity and the voltage of the battery. You can also estimate how long your solar battery can hold power based on the size. 

A 12V solar battery with a capacity of 200aH comes in 20.75 inches x 8.11 inches x 9.65 inchesOpens in a new tab.. This lithium-ion solar battery has 6 cells. 

The table below indicates the different sizes of solar batteries from DakotaOpens in a new tab. with their respective Voltage, capacity and dimensions.

Solar battery Dimension s(inches)
12V 7Ah5.94” x 2.55” x 3.74”
12V 10Ah5.94” x 2.55” x 3.78”
12V 18Ah5.94″x 3.95″x 3.78″
12V 23Ah7.12” x 3.03” x 6.57”
12V 54Ah7.12” x 3.03” x 6.57”
12V 100Ah12.99”x 6.77”x 8.66”

As seen from the table above, the higher the capacity of the battery , the larger the dimension and also the more the price. This means large batteries can hold power for long. 

Batteries with large capacity will take longer to charge fully. This is dependent on the size of solar panel. So how do you size a solar panel battery?

How do you size a solar panel battery?

Although the solar panel and the solar battery are not the same size, the amount of power needed to power your home is used to calculate the sizes of each.

The sizing of the solar panelOpens in a new tab. is determined by the load of the in kilowatts per hour to power your home.

Once you know the power needed you can therefore decide what size of solar battery you need. You will also use this data to decide the number of solar panels you need.

How to calculate battery storage capacity?

Knowing the capacity of your solar battery can help prevent unexpected blackout

  • To calculate the capacity of the solar battery you need to know the load requirement per day.
  • You will then have to know the type of battery you are using.
  • Incase you want to know the amount of energy tour solar battery can hold for three days without charging the battery. Multiply the total daily load by 3.

Battery Capacity = Total daily load power requirements (Wh) × 3

Conclusion

The size of your solar batteries will determine how long your solar batteries can hold power. For example large batteries with a large capacity will last longer than a battery with less capacity. 

Large solar batteries will also cost more than smaller solar batteries.
