Are solar panels worth it in 2026?

Key takeaways

• Solar panels absolutely work in the UK and can significantly reduce the amount of electricity you buy from the grid, even on cloudy days.
• The biggest savings come when solar panels are paired with a heat pump, battery storage and smart optimisation, helping you use, store and sell more of your own energy.
• Solar isn’t right for every home. Your roof, energy use and how long you plan to stay in your property all affect whether solar is worth it.

Yes, solar panels are worth it for many UK homeowners in 2026.

If your roof is suitable, your electricity use is high enough and you plan to stay in your home long enough to see the return, solar panels can cut your energy bills and reduce how much electricity you buy from the grid.

Add battery storage, a heat pump and smart optimisation, and the savings can go even further.

But solar is not right for every home. A shaded roof, low electricity use or a short-term move can change the maths. So before you install anything, it pays to understand what makes solar worth it.

Why solar panels are worth it now more than ever

Solar panels have changed a lot over the last decade.

Older solar panels were often less efficient, bulkier and not exactly easy on the eye. Modern panels generate more electricity from the same roof space, last longer and look much cleaner.

Aira solar panels deliver up to 470W of power with 23.5% efficiency. That means more clean electricity from every panel. Even when roof space is limited.

They are also built for the long run, with a manufacturer’s 25-year product warranty and 30-year performance warranty.

Do solar panels work in the UK?

Yes. Of course solar panels work in the UK.

We don’t exactly have the best weather in the UK, but solar panels don’t need blazing sunshine to generate electricity. They use daylight, which means they still produce energy on cloudy days. Less than on a bright summer day, of course, but they do not simply stop working when the weather turns grey.

That matters because the UK has plenty of daylight, even if it does not always feel like it.

The best results usually come from a south-facing roof with little shading. But east- and west-facing roofs can still work well. During a free home energy assessment, we'll check your roof size, angle, direction and shading to see what system makes sense for your home.

How much can solar panels save?

Because they generate their own electricity, solar panels reduce the amount of energy you need to buy from the grid.

Exactly how much you’ll save depends on your home. The size of your solar system, how much electricity you use and when you use it all make a difference. Generally speaking, the more solar electricity you generate and use yourself, the more you can save.

A typical Aira solar installation includes around 14 solar panels. Together, they can generate over 7,000 kWh of electricity each year. Enough to power a significant proportion of a typical UK home’s annual electricity needs.

Any electricity you don’t use can be exported back to the grid through a solar export tariff, creating an additional source of savings.

But solar panels are only part of the story

Solar panels can reduce your electricity bills on their own. But the biggest savings come when they’re part of a complete home energy system.

An Aira Heat Pump helps reduce the energy needed to heat your home. An Aira Power Store home battery lets you keep excess solar energy for later. Like in the evening when your panels aren’t generating, on cloudy days, or when electricity prices are at their highest.

And if you still have energy left over? You can sell it back to the grid.

Then there’s Aira Intelligence. Predicting how much solar you’ll generate, how much energy your home needs and when it makes most sense to use, store or sell your electricity.

The result is a home that relies less on the grid, uses more of its own clean energy and saves more on its energy bills.

Switch from a gas boiler to an Aira Heat Pump and you could save up to £490 a year on your energy bills. Add solar panels and the Aira Power Store home battery, and you could slash your annual energy bills by up to £1,392. That’s before you add your earnings from selling solar back to the grid.

Are solar panels worth it with a battery?

Without a battery, your home uses solar electricity as soon as it is generated. Any excess can be sold back to the grid.

But with a battery, you can store more of your own solar energy and use it later. Like in the evening, when your home still needs power but your panels are no longer generating.

A battery can also help you avoid buying electricity when prices are at their highest. Instead of drawing power from the grid during expensive periods, your home can use the energy you’ve already stored.

That means less electricity bought from the grid. More of your own clean energy used at home. And better control over your energy costs.

The Aira Power Store does exactly that. Powered by Aira Intelligence, it stores excess solar energy so your home and heat pump can use it when it matters most. Whether that’s after sunset, on a cloudy day or when electricity prices peak.

What happens to solar energy you do not use?

When your solar panels generate more electricity than your home needs, that excess energy can be exported back to the grid. And with the right export tariff, you can earn money for the electricity you send back.

This is where smart optimisation matters. Aira Intelligence predicts how much solar your panels will generate, looks at your home’s energy needs and helps decide when to use, store or sell your energy.

That means your solar panels, Power Store home battery and heat pump work together. Not as separate bits of kit, but as one smart home energy system.

When are solar panels not worth it?

Solar panels may not be worth it if your roof is heavily shaded, too small, north-facing or in poor condition.

They may also be less suitable if you use very little electricity, are rarely home during the day, cannot install a battery and plan to move in the next few years.

That does not mean solar is impossible. It just means the payback may be slower.

The simplest way to know is to get your home assessed properly. A good installer should tell you if solar is right for your home. Not just sell you panels.

That’s exactly what we’ll do. During your free home energy assessment, we’ll check if your roof is suitable for solar, design a system around your energy needs and show you how much you could save.

Do solar panels increase home value?

Solar panels can make a home more attractive to buyers, especially as energy bills keep rising and more people look for efficient homes.

According to Energy Economics, “Returns to solar panels in the housing market: A meta learner approach”, installing solar panels can increase your property’s value by up to £16,368.

That is not the only reason to install them. But it does mean the benefit is not limited to monthly bills. Solar can also make your home feel more future-ready.

Are solar panels worth it with a heat pump?

Yes. And this is where solar really starts to get really interesting.

As well as thermal energy from the air, a heat pump uses electricity to heat your home and hot water. Solar panels generate free electricity from your roof. Put them together, and your home can use clean electricity to help power clean heating.

Add the Aira Power Store, and you can keep excess solar energy for later. Add Aira Intelligence, and the system can help decide when to use, store or sell your energy. Without you needing to lift a finger.

That is the full Aira Home Energy System. Solar panels. Heat pump. Home battery. All working together.

More clean energy from your roof. Less reliance on the grid. And smarter savings without the hassle.

So, are solar panels worth it?

For many UK homeowners, yes.

Solar panels are worth it if your roof is suitable, you use enough electricity and you want to cut bills, reduce emissions and rely less on the grid.

They are even more powerful when paired with a heat pump, battery storage and smart optimisation.

Ultimately, solar panels on their own can help lower your electricity bills. Solar panels with Aira can help power your whole home energy system.
