Solar Battery Guide

For greater storage of energy from your panels, you need a quality solar battery but how can you tell a good one from a bad one? Getting this right can help you to make the most of your solar panels as a whole which is vital as they can be difficult to replace so you don’t want to have to do it too often.

The better solar batteries tick certain boxes than low-quality offerings struggle with. Once you know what to look for, you can enjoy better storage and long-lasting energy. The following guide will help you get this right.

How Does A Solar Battery Work?

The energy your solar panels produce needs to go somewhere when it is not being used, and a solar battery is that place. It is converted into DC (Direct Current) energy before the inverter turns it into AC (Alternative Current) that you use in place of your regular energy source at home.

The most common types of solar batteries are 120V and 230V and are used in both private and commercial properties.

What To Look For In A Solar Battery

Value

Because they are such a heavy-duty battery, they can be expensive. Still, there is no need to stretch your budget as you will find plenty of reasonably priced products. Plus, the savings you make over time in your energy bills make it an astute purchase.

The lifespan of the battery is key here so make sure it has a reputation for durability.

Voltage

This has to match the needs of your system so choose wisely. Also, it is hard to rectify if you install the wrong one although 24V and 48V are the most common in a lot of solar power storage.

Battery Storage

The solar battery you purchase needs to be able to store enough energy for it to be worth investing in. Otherwise, you could end up missing out on solar power and having to pay for regular power.

Power Rating

On top of battery storage, it also needs to be able to put the power to work, and in an efficient manner. There is little point in burning through all the power in a short amount of time. More storage and power means the solar can work on more appliances in your home for longer.

Easy To Install

The list of battery types below should give you an indication as to how difficult installing certain types of batteries can be. This being said, you also need to consider how much space you have to accomodate certain batteries.

The most convenient in terms of installation is lithium-ion but whatever you choose, if you are unsure as to how to install it properly, consult an electrician.

Charge Time

The faster your solar battery charges, the quicker you can use the energy and get it to storage more after. Although certain types of batteries are typically faster, it is also important to make sure that the brand you are looking at charges efficiently. Both Gel and lithium-ion batteries charge well.

Types of Solar Batteries

Flooded Lead Cell Batteries

A common solar battery that is one of the cheapest and reliable yet has a fair amount of downsides to consider. First of all, you need to keep them secure and ventilated to avoid leaking as they produce a gas. Also, they require regular checking to make sure everything is as it should be including the plates that should be submerged. This alone will require monthly attention to ensure the water levels are as they should be.

Not to mention they are larger than others.

GEL Batteries

Using silica to turn battery acid into a liquid, they are less durable but require next to no maintenance. They can be a decent option for those who want an off-grid system that they do not have to keep checking on. Still, they aren’t as reliable and are suspectable to overcharging because of their low charging voltage.

To top it all off, they are pretty expensive compared to flooded lead-acid batteries.

AGM (Absorbed Glass Mat)

Another lead-acid battery the battery plates are separated by a glass mat. Better for warmer climates as they can tolerate warmer conditions better than a lot of other batteries and require less maintenance since they do not leak. A lot of people like them because they are lighter, less bulky and have a good lifespan.

Lithium-ion

Popular but can be more expensive, they have a large storage capacity, are reliable and require very little maintenance. Also known for being efficient in how they use the power, Lithium-ion batteries are arguably the best solar battery available.

A great option as they last a long time but expect the initial outlay to be a lot higher than the other options.
