What is Solar Battery Storage?

A solar battery storage system provides a mechanism for storing excess solar power. The stored energy can later be used after sundown, during power outages, or when there is a surge in energy demand. Therefore, the installation of solar battery backup will go a long way in ensuring that little to no electricity is directed to the grid. This will help reduce the cost that you incur when buying electricity from the national grid afterward.

What are some of the benefits of installing a Solar Battery Storage System?

Having a solar system without a storage device only allows you to generate electrical energy that can only be used immediately. It may not meet your energy requirement since solar power is generated during the day when your demand for electrical energy is low. In many households, the need for electricity increases in the evening. By putting in place a solar battery, the solar power generated during the daytime is harnessed and stored in a solar battery to be used in the evening. Therefore, having a solar battery backup will go a long way in

Cutting down your electrical bills. Maximizing your self-consumption of your photovoltaic system. Reducing your dependency on the national grid for electricity.

What to consider when buying a solar battery

The majority of people don't know what to look for when purchasing a solar battery. Here are some insights that can help you decide which solar storage battery is the best for you.

Storage Capacity

The storage capacity of the solar battery should never be ignored. You should choose a solar battery with a storage capacity that can meet your home's energy requirement. A sound storage system should be able to supply a household with enough solar power throughout the night. If the storage system is not enough, then this may force you to go back to your pocket and purchase additional power to supplement your energy requirement. On the other hand, if the storage system is too large, the excess electrical energy is permanently stored. This reduces the service life of your storage system.

Depth of Discharge (DoD)

DoD refers to the amount of electrical energy in percentage withdrawn from the storage system. To prevent damage to the solar battery, the storage system must have a residual charge. For lead batteries, the DoD should be around 50%; while for lithium-ion batteries, the Depth of Discharge should be 100%.

The Energy Requirements of Your Household

For you to get the right solar battery storage for your household, you should first determine the energy required for your home. You can do this by checking your energy consumption pattern.

The Efficiency of the Storage System

In almost all storage systems, they usually experience conversion losses, which happens when some electrical energy is converted into heat. The total efficiency points out at the actual percentage of electrical power stored that is usable. Therefore, we strongly advise our clients to choose a storage system whose overall efficiency is above 90%.
