Undoubtedly, solar panels are the key component in converting sunlight into electricity. But have you ever wondered what happens to the extra power your solar panels generate during the day?
How can you power your homes at night or on cloudy days?
With the rising need for energy independence and environmental sustainability, solar batteries emerge as a perfect and efficient solution for storing excess energy for later use.
So, when solar batteries are paving the way for a more sustainable, energy-efficient, and eco-friendly future, it has become essential to know more about their role and why they are a game-changer for Australia’s energy future.
Ready to discover how solar batteries work and why they matter?
Let’s get started by reading this beginner-friendly guide explaining the fundamental workings of solar batteries!
What Are Solar Batteries? | How Solar Batteries Turn Sunlight into Nighttime Power?
In general, solar batteries are devices designed to store the excess energy produced by solar panels during peak sunlight hours. The solar panel captures sunlight and converts it into electricity, which is then stored in the batteries to power your home.
During summer in Australia, when the days become longer with more sunlight hours, your panels often generate more power than your household needs.
Instead of sending this surplus energy back to the grid, your batteries keep it stored for later use when solar energy production lowers or electricity price spikes.
From Panels to Power: The Essential Parts of a Solar System
A solar energy system consists of several key components that work collaboratively to capture, convert, store, and use solar energy. These components list include:
- Solar Panels: Solar panels or photovoltaic (PV) panels are made of semiconducting materials such as silicon. When sunlight falls on their surface, the materials inside the panel generate an electric current.
- Solar Inverter: It’s a device that converts DC electricity from the panels into AC electricity, as most of our home’s appliances run on AC power.
However, to fully utilize the energy generated by your solar panels, you need a reliable way to store it.
In Australia, if you’re connected to the power grid, the process is straightforward. Excess energy can be fed back into the grid to maximize savings from feed-in tariff programs.
But what if you’re living off the grid?
Then, you need additional components such as batteries and charge controllers. Thinking why?
- Batteries: store the energy you generate for later use, enhancing grid stability while making it more sustainable and cost-effective
- Charge controllers: This component regulates the flow of electricity between the solar panels, the battery, and the inverter.
It ensures the battery doesn’t overcharge or discharge too quickly. It also helps to extend the battery lifespan and improve storage system efficiency.
Overall, these parts work together harmoniously to ensure a consistent, reliable energy supply even when the sun isn’t shining.
Unleash the power of the Sun: The Inner Workings of Solar Battery Storage!
Now, let’s explore how solar storage systems work in a synchronized manner to create a seamless flow of energy.
Well, the process is relatively simple:
Solar panels capture sunlight and convert it into electricity, which is then stored in batteries.
The charge controller ensures that the batteries are charged efficiently and safely. Hence, when you need power, the energy flows back from the batteries to your home, providing a steady 24/7 electricity supply.
So, here’s a more detailed step-by-step breakdown of how solar batteries work:
Step 1: When sunlight hits your solar panels, they generate direct current (DC) electricity.
Step 2: A solar inverter converts DC electricity into alternating current (AC) electricity, which is the type used in most homes.
Step 3: The switchboard then directs the converted solar energy to power your home appliances.
Step 4: After running all the essential household appliances, any surplus energy is again routed to the battery inverter.
Step 5: The battery inverter changes the excess energy into a storable form (AC).
Step 6: This AC electricity is stored in a solar battery for future use.
When solar energy production drops, such as at night or on cloudy days, all the stored energy one solar battery holds is used to power your home.
This process ensures that homeowners can rely on clean, renewable energy even when their solar panels aren’t actively generating power.
