What is Solar Battery Storage?
Solar Battery Storage is a technology that allows homeowners to store excess energy generated by their solar panels during the day, for use during the nighttime. It works by charging batteries with the surplus electricity instead of exporting it to the grid, reducing reliance on external sources for energy consumption.
How it works
Solar panels on your home catch the sun's light. They turn this light into power for your house to use during the day. Any extra energy is put into a solar battery storage system. This stores the power until you need it at night or when there is a power cut.
Once the sun goes down, or if there's a blackout, this stored energy comes back out of the battery and gives you electricity. So even when it gets dark, or if all other homes lose electricity, you've got power from your saved-up sunlight!
Benefits of storing excess energy
Storing excess energy has many benefits for homeowners who have solar panels. Here are some key advantages:
- Maximising self-consumption: By storing excess energy, you can use it during nighttime hours when your solar panels aren't generating electricity. This reduces your reliance on the grid and maximises the usage of your solar power.
- Saving money: Storing excess energy allows you to avoid purchasing electricity from the grid during peak times when rates are higher. This can lead to significant savings on your energy bills.
- Energy independence: With a solar battery storage system, you become less dependent on the grid for your energy needs. This is particularly beneficial during power outages or emergencies when the grid may be down.
- Environmental impact: Storing excess energy allows you to further reduce your carbon footprint by using clean, renewable energy even at night or during cloudy days when solar production is limited.
- Grid stability: By storing excess energy and using it during peak demand periods, you contribute to a more stable electricity grid by reducing strain and potential blackouts.
- Long-term cost savings: Investing in a solar battery storage system can provide long-term cost savings as it extends the lifespan of your solar panels and reduces the need for maintenance or replacement.
Reducing reliance on the grid
One of the benefits of solar battery storage is its ability to reduce reliance on the grid. With a solar battery system, you can store excess energy generated by your solar panels during the daytime and use it at night when there isn't enough sunlight.
This means that you don't have to rely solely on the electricity from the grid during nighttime hours, reducing your dependence on traditional power sources. By using stored energy instead of drawing from the grid, you can further maximise your savings and decrease your carbon footprint.
Solar battery storage gives you more control over your energy usage and allows for greater independence in meeting your home's electricity needs.
Types of Solar Battery Systems
There are two main types of solar battery systems: DC Battery Systems and AC Battery Systems.
DC Battery Systems
DC battery systems are one type of solar battery storage that homeowners can consider. These systems store excess solar energy generated by the PV panels in DC form, which is then converted to AC for use in the home.
DC battery systems are an efficient way to store and utilise surplus electricity, providing a reliable source of power during nighttime hours when the sun isn't shining. They also offer backup power during power outages, ensuring that essential appliances and devices continue to function.
With different sizes and capacities available, homeowners can choose a DC battery system that meets their specific energy storage needs.
AC Battery Systems
AC battery systems are another type of solar battery storage solution. AC stands for alternating current, which is the type of electricity that comes from the power grid and is used in most homes.
These batteries are designed to integrate seamlessly with your existing electrical system.
With AC battery systems, the excess solar energy generated by your panels is first converted into direct current (DC). Then, it goes through an inverter that converts it back into AC before being stored in the batteries.
One advantage of AC battery systems is their compatibility with standard household appliances and devices. You can use this stored energy during nighttime when your solar panels aren't producing electricity or during power outages.
The batteries act as a backup power source, ensuring that you have reliable electricity when you need it.
Considerations for Solar Battery Storage
