Home Batteries: 5 Steps from Simple Guide to Professional User

Aktualisiert: 28. Nov. 2023



1.) Home Batteries: A Simple Guide

Imagine a big rechargeable battery in your house, like the ones in your phone but much bigger. This big battery can save electricity when you don’t need it and use it later when you do. This is super helpful if you have solar panels on your roof because they make electricity only when the sun is shining. On cloudy days or at night, they don't make electricity. So, storing the extra power from sunny days means you can still use solar power even when it's dark or cloudy. Usually, if you make more electricity than you use with your solar panels, it goes back into the big electricity network and you get a small amount of money for it. But it's often better to keep and use this electricity yourself. That’s where your big home battery comes in handy.

Batteries and Saving Money Your big battery can do another cool trick. It can store cheap electricity from the main power grid when it's not expensive (usually at night) and then use it during the day when electricity costs more. This can help save money on your electricity bill. There’s a special government program called the Smart Export Guarantee (SEG) that pays you for the electricity you send back to the grid. This includes the power stored in your battery, but only certain batteries can do this.

Costs and Saving Money These big batteries can be pricey, and it might take several years to save as much money on your electricity bill as you spent on the battery. How quickly you save depends on:

  • How big your solar panel setup is.

  • How big and costly your battery is.

  • How much electricity you use when there’s no sun.

  • The cost of electricity from the grid.

  • If you have things like a heat pump in your house.

  • How much money you get from sending electricity back to the grid.

Let's say you use a certain amount of electricity every year. If you have solar panels and a big battery, you can use more of the solar power you make. This means you buy less expensive electricity from the grid, saving you money. But you need to think about how much the battery costs and how long it will last.

More About Batteries Not all batteries will give you power when there's a blackout. Some will, but they might cost more.

Electric Cars Think of an electric car as a big battery on wheels. Some cars can even power your house like a big battery! But usually, people choose either a big battery at home or an electric car, not both.

Are Batteries Good for the Planet? Using a big battery can help use more solar power and less grid power, which is often good for the environment. But making batteries can create pollution, too. So, it's a bit of a mix.

Should You Get a Big Home Battery? It depends. Batteries are getting cheaper and better, so in the future, they might save you more money and be better for the planet. But right now, it's different for everyone. If you really want to help the planet, maybe focus on using less energy, getting a heat pump, or driving an electric car.

Choosing a Battery Here’s what to think about when picking a battery:

  • Capacity: How much electricity it can store.

  • Number of Cycles: How many times it can be charged and used up.

  • Charge/Discharge Rate: How fast it can be charged and how much power it can give out.

  • Back-Up Power: Do you need it to work during a blackout?

  • Price per kWh: How much it costs for the amount of electricity it can store.

  • AC or DC Coupling: This is about how it connects with your solar panels.

  • Installer: Make sure they know what they’re doing and have the right certifications.

That’s it! Big home batteries can be great with solar panels, help save money, and can be good for the planet, but they're not the perfect solution for everyone just yet.


More Tips on Home Batteries If you're thinking about getting a home battery, here are a few more things to keep in mind:

  • Use What You Make: The best part of having a solar panel and battery setup is using the electricity you produce. Instead of sending extra power to the big grid, you store it for when you need it. This is especially handy at night or on cloudy days.

  • When to Use Your Battery: The battery can store power when it's cheap, especially at night, and then you can use it when electricity is usually more expensive. This means during the busy hours of the day, like late afternoon and early evening, you're using cheaper stored electricity instead of buying it at a higher price.

  • Size Matters: The size of your solar panel setup and your battery should match your needs. If you have a small solar panel system, you might not need a very big battery. Your installer can help figure out the best size for you.

  • Think About the Future: Battery technology is getting better and cheaper. If a battery doesn't make sense for you right now, it might in a few years. Keep an eye on new developments.

  • Check Your Needs: Before deciding, think about how you use electricity. Do you use a lot at night? Do you have appliances that use a lot of power? This will help decide if a battery is right for you.

  • Look at the Whole Picture: Remember, a battery is just one part of your home energy setup. Think about how it works with your solar panels, any electric heating or cooling systems you have, and how you use electricity overall.

  • Maintenance and Warranties: Check how much maintenance the battery needs and what the warranty covers. This can save you from unexpected costs later.

  • Government Programs and Incentives: Sometimes, there are special government programs that can help with the cost of a battery or give you extra benefits for using renewable energy.

  • Be a Smart Shopper: Compare different batteries and prices. Look for reviews and ask for recommendations. Cheaper isn't always better, but the most expensive one might not be the best for you either.

  • Professional Help: Always get a professional to install your battery. They'll make sure it's done safely and works well with your other systems.

By thinking about these points, you can make a better decision about whether a home battery is right for you. It's all about finding the balance between your needs, your budget, and what you want to achieve, like saving money or helping the environment.
