When the sun goes down, do you ever think about how you’ll keep your home or farm running? 

Obviously, the use of solar-powered batteries! 

Solar batteries are a sustainable, continuous, and dependable energy source because they can collect energy from the sun throughout the day and store it for later use. This is so that the power may be utilised right when it’s required.

Solar energy is cheaper than fossil fuels in the long run, but that doesn’t mean you’ll see savings right away if you convert to solar power and install panels on your roof. Choosing the right solar battery system might be crucial to protecting your investment in a solar energy system over time. This is why it’s so important to do your research before making any decisions.

One may choose from a number of different solar battery types, each with its own set of pros and cons. There are a lot of factors to think about when selecting the best solar battery for your needs, but we’ve broken them down into more digestible pieces for you here.

Capacity

The capacity of a solar battery is the maximum quantity of energy that can be stored in it. Most solar batteries are limited in their ability to store and release energy. A common solar battery, for instance, has a capacity of 90%, which means that a battery rated for 10 kW can only really use 9 kW.

The storage capacity is determined by the total quantity of energy your solar panels will produce in a day. Knowing the normal output and multiplying it by the desired number of days of continuous use before recharging the battery is necessary. 

If you have an average daily production of 5 kW and need to store energy for 15 days, you’ll require a battery with a capacity of around 75 kWh. The Solar Battery’s storage capacity, however, will be set by the peak daily power requirements of your farm.  Choosing the California solar battery is a good idea here.

If your solar battery is too small, it won’t be able to store enough energy to last the required period of time.

Efficiency

A battery’s Round Trip Efficiency is the proportion of its stored power or energy that may be utilised during a single cycle.

Consider a solar battery that, when fully charged, has a 5-kWh capacity but only supplies 4-kWh to the device. When employed in a circular fashion, its efficiency would increase to 80%.

DoD is an abbreviation for “depth of discharge.”

The depth of discharge is the sum of the power used by the battery during the discharge process. A battery with a 10 kWh capacity and a 90% discharge capacity, for instance, may be discharged to 9 kWh before needing to be recharged, with the remaining capacity being stored until needed. To work, solar batteries always need to have some energy stored in them. If this is not done, they will have a much shorter life expectancy.
