Choosing solar batteries for your solar panel system can be a difficult task. There are many different types of solar battery technologies to choose from, and choosing the right solar battery will depend on what your needs are.
To help you choose the best solar battery to pair with your solar panel system, we’ve broken down the key factors you should keep an eye out for in our solar battery buyer’s guide.

Solar batteries technology
Understand what different types of solar battery technologies & energy storage options are there before making a purchase decision.
There are three main categories currently available on the market - nickel metal hydride (NiMH) batteries, nickel-cadmium (NiCd) batteries, and lithium-ion (Li-ion) batteries.
NiMH solar batteries are more affordable but have a lower energy storage capacity than Li-ion solar batteries, which means that if you want to store enough solar power for the winter days when there is not as much sun then you will likely need to install additional solar panels and purchase two or three lithium-in solar battery packs.

Battery capacity
A battery’s capacity shows how much electrical power can be stored in a battery. This value is commonly expressed in kilowatt hours. The majority of batteries for residential use are separate modules that can be stacked together to expand the capacity of the solar+storage systems.
In other words, capacity is a battery’s size. However, this parameter does not show the amount of power that can be withdrawn from the battery at once. So, you also have to take into account power rating, which is how much energy can be provided by a battery momentarily. This parameter is expressed in kW.
High-power and low-capacity batteries can power the whole house for several hours, while low-power and high-capacity batteries are able to provide little energy during long periods.

Round-trip efficiency
The round-trip efficiency of a solar battery represents the amount of energy you can use from your solar battery compared to the amount of energy it took to store that energy.
Say your solar panels sent 10 kWh of electricity to your battery, but only 7 kWh of that electricity was actually stored and can be used. That means 3 kWh was used by the battery’s operating system to store and release the electricity, making the battery’s round-trip efficiency rating 70%.
Our advice is to go for a battery with an efficiency rating of 80% or higher. Higher efficiency batteries can save more money in the long run because more of the solar electricity produced can be used by your appliances, instead of being lost to the battery storing the energy.

Battery lifespan
Battery lifespan is the measure of the longevity of a battery with regular use. With continuous use, a battery gradually loses its ability to hold a charge.
A battery lifespan is typically measured in years, estimated cycles, and estimated throughput. Consider going for solar products for home warrantied to operate at least 70% of their original capacity after 10 years or 10,000 cycles.

Warranty
There are a variety of Solar batteries available in the market, but all are not reliable and trustworthy. When choosing a Solar battery, your best bet is to select one of high-quality and mid-range. These tend to have a long cycle life, which means they can cycle many times over their lifespan without losing capacity.
You should look at the manufacturer’s warranty and return policy to ensure they protect your investment if something goes wrong during installation or operation.
