Why Battery Storage and Solar Panels are the Perfect Combination

If you’re already thinking about going solar, you’ve probably wondered whether battery storage and solar panels are worth it. 

Well, the truth is that not only is battery storage or solar battery storage worth it with solar, but battery storage done right is what turns a good solar system into a great one.

At Sunbright Energy, we’ve seen time and again how adding a battery to your solar panels doesn’t just reduce bills – it transforms the way you power your home. For homeowners across Kent and the South East, battery storage is the key to making the most of your investment and gaining real energy independence.

Let’s break down why battery storage is the perfect partner for solar panels – and why it makes sense to add it from the start.

What is Solar Battery Storage?

Think of a solar battery as your household’s energy bank.

During the day, your panels often generate more electricity than you’re able to use in the moment. Without a battery, that spare energy gets exported back to the grid, and you’ll have to buy power back later in the evening when you need it most.

With battery storage, you keep that energy for yourself. The electricity your panels generate at midday can power your home during the evening peak – meaning more of your home runs on free solar, not expensive grid electricity.

How Battery Storage Helps You Save More

Use more of the solar you generate

Solar panels alone can cut your bills by around 40%. That’s already a big difference. But when you add a battery, savings typically climb to 70-80%.

To put that into perspective:

• If your monthly bills are £200, panels alone might save you around £80.
  
• With battery storage, you could save closer to £160.

That’s not just a little extra – it’s a game-changer. 

Take advantage of off-peak tariffs

Here’s where battery storage gets even smarter. With the right setup, you don’t just store solar energy – you can also buy cheap electricity from the grid during off-peak hours.

Many smart tariffs in the UK let you charge your battery overnight at much lower rates. You then use that stored energy during the day when electricity is more expensive.

For example, E.ON are currently offering their Next Drive Smart 5.2 smart tariff. On this tariff, peak electricity prices are 28.1p/kWh. That’s a pretty standard cost of electricity in the UK. However, from 12am – 6am, electricity is just 6.5p/kWh. You can use this cheap energy overnight to charge your battery, and then use it once you’re up in the morning.

That’s a 77% discount on the energy that you’d be buying from the grid anyway!

It’s like filling your tank with fuel at a fraction of the price and driving on it all week.

The Long-Term Benefits of Battery Storage

Adding a battery to your solar system isn’t just about today’s savings – it’s about protecting yourself for the future.

By investing in battery storage, you’ll get:

• Lower reliance on the grid – The less you depend on grid power, the less you’re exposed to unpredictable price hikes.
  
• Energy security – Use your own stored power when you need it most.
  
• Increased property value – Homes with solar and battery storage are highly attractive to future buyers, and have been shown to sell for £10,000 – £15,000 more than those without
  
• Environmental benefits – By storing and using more of your solar energy, you reduce your reliance on fossil fuels even further

Drawbacks of Battery Storage

The only real drawback of battery storage is the upfront cost. It does make your system more expensive than solar panels alone.

But here’s the flip side: because you’re saving so much more in the long run, batteries usually pay for themselves faster than expected. Most solar systems with battery storage pay for themselves in 6-10 years, and they’ll continue to deliver savings for 10-15 years beyond that.

Think of it less as an extra cost, and more as an investment that multiplies the returns of your solar system.
