Best Batteries For Solar Systems

If you are thinking about investing in solar energy, it can be a great avenue for your home— using solar energy comes with significant energy savings, meaning you will save a lot of dollars, too.

One of the parts of a solar energy system that you will need to research is the solar battery. Below, we will go into further details on the batteries you should look into for a solar energy system, as well as some information to educate you on this important device in your solar energy system! 

What Batteries Do I Need For a Solar Energy System?

One of the necessary parts of a solar energy system is the battery, and there are a few types of batteries to choose from. Read on to learn more about the types of batteries that you can use for a solar energy system, as well as which type of battery is considered to be the choice.

Lead Acid Batteries

A lead acid battery is a battery that uses lead and sulphuric acid. It is a rechargeable battery, as are the other two on this list, and can be used for your solar energy system. When a lead acid battery is working, the lead is first submerged into the sulphuric acid. This creates a chemical reaction which then causes the battery to create electricity. To recharge the battery, this controlled chemical reaction and process is simply reversed. An important thing to note is that lead acid batteries will discharge on their own, so they will slowly start to lose their charge.

Lithium Ion Batteries

Lithium-ion batteries are believed to be the best battery option for a solar energy system. This type of battery is the same type of battery used in rechargeable devices like cell phones or electric cars. A lithium-ion battery works by using the reversible reduction of lithium ions in order to store energy— in this case, solar energy! As we mentioned above, this is a rechargeable type of battery. If you are looking for a battery for your solar energy system, it will need to be a rechargeable battery. 

Saltwater Batteries

A saltwater battery is a battery that uses a concentrated saline solution as its electrolyte. They are non-flammable and can be recycled easily, unlike other kinds of batteries.

Weight vs Size vs Charge

One of the important things to consider when shopping for solar batteries is that the weight and size can make a difference! There are one size fits all solar batteries, but these are not necessarily the best choice for you out there. This is because they are standardized, but usually either undersized or oversized for your needs. If undersized, they won’t be able to meet your power demands, but if they are oversized, they may not get to full charge, especially in winter. Instead, you should look at the battery capacity in amp hours of the battery you are researching.

Solar Batteries For Camping

A solar battery can be very important for you when you are camping, as you want to be sure you are able to power the devices that you have brought along with you! Below, we will go over a few great solar batteries to invest in for your camping trips.

Battle Born LiFePO4

One of the options out there for a portable camping battery option is the Battle Born LiFePO4. This is a lithium-ion battery and is cost-effective and easy to install. It is also versatile, which is important if you want to take it camping with you! It has a capacity of 1.2 kWh.

In addition to all of this, the Battle Born LiFePO4 is a battery that comes with a 10-year warranty, so it will last you for at least 10 years before needing to be replaced. 

Fullriver AGM Sealed Lead Acid Battery

Another great option for a camping battery is the Fullriver AGM Sealed Lead Acid Battery. As the name suggests, this is a sealed lead acid battery, rather than a lithium-ion battery like the Battle Born battery. Typically, lithium-ion batteries are the best battery choice when you are buying a solar energy system.

This battery has a capacity of 1.5 kWh. It is also designed so that it has a high reserve capacity and a low internal resistance.

However, it is important to note that this battery weighs 123 pounds, so it will only be a good choice if you are staying at one campsite and not moving around— or are camping with your RV for easy transport!
