How does Solar Battery Storage work?

Solar panels are an excellent source of renewable energy, but they create most of their energy only when the sun’s out and about, and the weather is clear. That’s when solar battery storage comes in very handy.

Solar panels are an excellent source of renewable energy for powering the home.

They are sustainable, as they enable you to generate your own energy rather than relying on the grid. Because solar panels ensure your home draws less energy from the grid, it’s also a cost-effective method of powering your home – in short, it can help you save money on your electricity bills.

However, solar panel installation is only one component of a sustainable solar system.

Equip your solar energy system with a battery

Solar panels are an excellent start, but they provide electricity only when the sun shines. This is when a solar battery is required.

It saves wasted solar energy for use at night or on gloomy days. You’re paying even less for grid energy, so it’s still an excellent strategy to increase your solar energy production.

Additionally, a battery could enable you to contribute to your local community. It may communicate with other solar home batteries in your neighbourhood to form a Virtual Power Plant and assist the grid when needed, such as on a hot day when a large number of people switch on their air conditioning simultaneously.

How do solar panels and batteries operate in conjunction with one another?

A home solar system is composed of several components. To begin, you’ll need solar panels that feed energy into an inverter. The energy is then directed to the appliances in your home via a switchboard.

When the sun isn’t shining, the grid takes over to keep the lights on. If you generate more solar energy than you consume, the excess energy is fed back into the grid, and you receive a solar feed-in tariff (FiT) credit on your electric bill.

However, if you have a battery solar system installed, the switchboard transfers any surplus solar energy generated to the battery, thereby charging it for later use. When the sun sets or you consume more energy than your panels generate, the stored energy in your battery powers your appliances. And if your battery runs out, the grid will assist you.

This is an illustration of how an AC-coupled battery storage system works. It involves the addition of a battery to an existing solar system.

  1. Solar panels absorb solar energy.
  2. Solar energy is transformed to alternating current (AC) energy that may be used by everyday appliances via the solar inverter.
  3. After that, the switchboard transfers the solar energy to the appropriate locations. It will power your home’s appliances first, then divert any excess energy to the battery inverter.
  4. The battery inverter transforms the energy to a form that may be stored.
  5. The battery stores energy for use after the sun sets.

In this case, the battery is charged, and the residence is powered without the use of grid energy.

And then, when the sun sets…

At night, an animated house powered by solar panels and a battery generates energy.

Solar panels are switched off and the residence uses saved battery energy.

  1. The battery begins supplying energy to the residence via the battery inverter.
  2. The battery inverter transfers the energy to a form suitable for usage by appliances.
  3. The switchboard is responsible for directing energy to your appliances.
  4. When the battery’s charge is depleted, the grid automatically kicks in and supplies electricity to keep your appliances functioning.
