A solar battery can be an important addition to your solar power system. It helps you store excess electricity that you can use when your solar panels aren’t generating enough energy and gives you more options for how to power your home.
If you’re looking for the answer to, “How do solar batteries work?”, this article will explain what a solar battery is, solar battery science, how solar batteries work with a solar power system, and the overall benefits of using solar battery storage.
What is a Solar Battery?
A solar battery is a device that you can add to your solar power system to store the excess electricity generated by your solar panels.
You can then use that stored energy to power your home at times when your solar panels don’t generate enough electricity, including nights, cloudy days, and during power outages.
The point of a solar battery is to help you use more of the solar energy you’re creating. If you don’t have battery storage, any excess electricity from solar power goes to the grid, which means you’re generating power and providing it to other people without taking full advantage of the electricity your panels create first.
Is solar battery storage right for my home?
If you have solar PV panels or are planning to install them, then using home batteries to store the electricity you’ve generated will help you to maximize the amount of renewable energy you use.
Home-energy storage will also reduce the electricity you use from the grid, and cut your energy bills.
How Solar Batteries Work with a Solar Power System
Here is a step-by-step breakdown of what happens with a DC-coupled system:
- Sunlight hits the solar panels and the energy is converted to DC electricity.
- The electricity enters the battery and is stored as DC electricity.
- The DC electricity then leaves the battery and enters an inverter to be converted into AC electricity the home can use.
What size solar storage battery do I need?
The average home uses around 8kWh of electricity per day. The capacity of new lithium-ion batteries ranges from around 1kWh up to as much as 15kWh.
Ideally, you want a battery that will cover your evening and night-time electricity usage, ready to be charged up again when the sun comes up. You’ll also need to bear in mind how much your solar panels can generate, as there’s no point in buying a battery that’s bigger than it can fill.
With a well-chosen battery for your home’s energy use and your solar panels’ output, you should find that you can have enough electricity to serve your evening needs for most of the year. You might find that you are still drawing on grid electricity for some of the longest winter nights.
Battery lifetime is measured with three different metrics:
Expected years of operation
Battery life is defined in years, while a battery’s expected throughput and cycles are like a car’s mileage warranty.
Solar batteries have a super high lifecycle. This means that they don’t require frequent maintenance or replacement. The good news is that they still remain highly functional after charging and discharging solar batteries thousands of times.
Solar panels are a great way to generate renewable energy and save money on your electricity bill. There are many factors to consider when choosing solar panels, including the amount of sunlight you receive, and the type of solar panel you want.
