Solar Energy Storage: Everything You Need to Know

Solar power is an renewable and infinite energy source that creates no harmful greenhouse gas emission. Storing solar energy has becoming increasingly popular in many countries due to its limitation – the electricity are only produced when the sun is shining. To store solar energy for later use can improve the self-consumption of home solar system. In this blog post, we’ll explore everything about solar energy storage.

How Does Solar Power Work?

In short, solar power works by converting energy from the sun into power. For residential rooftop solar, the electricity is converted by Solar panels from sunlight. That means, the conversion from sunlight to electricity only works during daytime with sufficient PV. Solar panels often produce more than enough energy during those lower demand hours but fail to meet the peak demand later in the day without storing solar energy.

What is Solar Energy Storage?

Solar energy storage is to use a device that reserves energy from solar power system for later consumption. The stored electricity is consumed after sundown during peak demand hours or as emergency backup. Solar power energy is commonly on residential or commercial buildings.

Energy Storage System Types

Solar Battery Energy Storage: Solar energy storage works by adding a battery to the existing solar system installed at home.

Compressed air energy storage: With these systems, generally located in large chambers, surplus power is used to compress air and then store it. When energy is needed, the compressed air is released and passes through an air turbine to generate electricity.

Mechanical gravity energy storage: One example of this type of system is when energy is used to lift concrete blocks up a tower. When the energy is needed, the concrete blocks are lowered back down, generating electricity using the pull of gravity.

Flow batteries: In these batteries, which are essentially rechargeable fuel cells, chemical energy is provided by two chemical components dissolved in liquids contained within the system and separated by a membrane.

Benefits of Solar Energy Storage

Unlike grid-tied solar system, the excess electricity is pushed onto the local grid. Home solar energy storage is handy for

  • Off-grid solar system
  • Backup power during power outage
  • Ares without net metering policies

With the solar panel energy storage batteries to store the excess energy can greatly improve the self-consumption of solar system. Storing solar energy has a few main benefits:

Improve Self-consumption of solar system: energy storage allows surplus generation to be banked for peak-use.

Saving from electricity bills: if you live on where has no solar net energy metering or feed-in policies, battery storage can help you to lower your electricity bills.

Energy Independence: with solar energy storage, you can living completely off-grid. Solar batteries provide you a self-sufficient energy solution during wildfires to severe weather.

Required Components for Solar Energy Storage

Solar energy storage needs the following main components,

Solar Panel

Solar panels allow you to charge your battery with clean renewable energy. 


The battery is the key components of energy storage system. Lithium-ion battery is the most economically viable energy storage solution. SVC LFP Solar rechargeable battery.


The function of inverter is to convert energy from AC to DC and vice versa.  Some inverter now include a built-in solar charge controoler into their components – SVC Solar Inverter.
