The need for solar energy storage, also known as solar batteries, is rising among many Zimbabwean as the energy sector continues to alter and develop rapidly. 

Finding the best energy storage solution for your house might feel overwhelming as more solar brands and models enter the market, particularly when you try to understand the ins and outs of solar battery efficiency and capacity.

What is a Solar Battery?

With a solar battery storage system, you may reserve the solar energy you produce during the day for usage at night.

Most solar panel systems produce electricity during the day when many people do not require it. Instead, extra electricity might be kept in a solar battery.A solar battery is a wise purchase when connected with solar energy systems. Customers can store extra energy produced by solar panels using solar batteries. 

If accessible, the stored energy can be sold back to the power grid for electricity bill credits, used during periods of lower output, like at night or during a brief power outage. This procedure is known as net metering.

How do Solar Batteries work?

Solar batteries are installed alongside solar panels to store excess energy. It can be used as stored energy when the sun sets at night, and your panels can no longer provide your home power. Most battery storage options include an inverter for converting stored voltage to the AC voltage you need. Solar batteries also offer blackout protection. While the rest of your street may be in darkness, your home can continue to use the energy stored in the battery to power your appliances and keep the lights on!

Types of Solar Batteries

There are various kinds of batteries that can use on solar systems. The term type describes the chemical content of a battery. Lithium-ion batteries are the most commonly used, but you’ve probably heard of lithium-ion batteries, gel batteries, deep cycle batteries, and many others.

The solar industry offers more than different batteries to store extra energy. Lead-acid or lithium-ion batteries are the two battery types used most frequently in home solar power systems.

Lead-acid Solar Batteries

Lead-acid batteries require frequent recharge and a lower depth of discharge (DoD). These battery types are uncommon for homeowners who want to use solar energy continuously.

Still, they can be a good backup option in a power outage. Lead-acid batteries come in two varieties: sealed lead-acid and flooded lead-acid batteries. While the latter doesn’t require as much maintenance as the former, the former has a longer lifespan.

What is DoD mean?

The depth of discharge (DoD) of a battery represents the proportion of the battery’s total capacity that has been discharged.

A battery’s lifespan will decrease the more it is charged and discharged. A battery should usually only be partially discharged because doing so significantly reduces the battery’s usable life. Many battery manufacturers offer a maximum DoD ideal for the battery’s performance.

For instance, if a 10 kWh battery’s manufacturer advises a maximum DoD of 80%, you should only consume up to 8 kWh from the battery without recharging. You can see why DoD is significant to take into account: a higher DoD allows you to utilise more energy stored in your battery. Nowadays, a DoD of 100% is advertised on many contemporary lithium ion batteries.

Lithium-ion Solar Battery:

Lead-acid batteries are older; lithium-ion batteries are often lighter and smaller. They typically have a minimum lifespan of 10 years and a longer DoD. The fact that lithium-ion batteries require less maintenance than many of the alternatives is another benefit.

Lithium-polymer Battery

These are similar to lithium-ion batteries. However, they are frequently more expensive and last less time. They are safeguarded against overcharging or leakage, which is a bonus.

Deep-cycle Battery

These solar batteries work well to maintain a steady stream of electricity over a longer time.

Saltwater Battery

These saltwater-based solar batteries are a more natural and green alternative because they use water rather than oil as the electrolyte. The lifespan of saltwater batteries is often very lengthy, and they require no maintenance.

Solar gel Battery

Solar gel batteries are a wonderful choice for solar owners who travel frequently. These batteries are perfect for RV owners or anyone who want to travel with a solar battery because they don’t have to stay upright and can move around quickly.

What criteria should I compare when buying a solar battery?

Before investing in one of the many solar power options available, you need to know what you want. List some important categories to distinguish good from bad.

Battery size

  1. Cycle life: The number of times a solar battery may be fully charged and drained before the performance starts to suffer is referred to as its cycle life. Getting a solar battery with a high cycle life is preferable to get the most out of your investment.
  2. Warranty: These days, a solar battery has a lifespan of about 10 years, but check for restrictions and local warranty support.
  3. Functionality & Efficiency: This gauges the battery’s efficiency throughout one cycle. Batteries require energy, just like many other things in your house. It implies that they will consume part of the energy they store. The percentage of electricity you can recover from the battery after using the energy it requires is known as round-trip efficiency. If a typical 10 kWh battery only allows you to draw out 8 kWh, then its round-trip efficiency is 80%. Since round-trip efficiency only considers one battery cycle as opposed to a battery’s whole lifespan, it differs from DoD.
  4. Cost: It is best to shop around and pick a solar battery that suits your budget because solar batteries might range in price.
  5. Usable storage capacity: The energy your battery can hold at once, expressed in kilowatt-hours (kWh), is its capacity. The typical solar battery has a 10 kWh capacity.
