How Much Can I Save with Solar Panels?

Real-World Savings Examples

Here’s what different types of homes might typically save each year:

• A small 2-bedroom home with a 3kW system could save around £500 to £700 per year.
• A 3-bedroom semi-detached home with a 4kW system and a small battery might save £900 to £1,200 annually.
• A detached family home with a 6kW system and medium-sized battery could save £1,200 to £1,600.
• A large home with high usage and an EV charger might save £1,500 to £2,000 per year with a large system and battery.

These are averages — your actual savings depend on your energy use, roof size, system design, and tariff.

How Long Until It Pays for Itself?

• A solar panel system (without a battery) typically pays for itself in 6 to 8 years.
• A system with battery storage pays back in about 8 to 10 years.

After that, you're effectively generating free electricity for the next 10 to 20 years.

Over the full lifetime of the system, many homeowners save £20,000 to £30,000 or more.

What Affects How Much You Save?

Several key factors determine how much value you get from solar:

Your daytime usage
The more electricity you use during daylight hours, the more value you get from your solar panels.

System size
A properly sized system gives you maximum return. Too small = missed savings. Too large = wasted potential.

Tariff type
If you're on a smart tariff (like Octopus Go), you can charge a battery cheaply and avoid peak-time costs.

Battery storage
A battery allows you to store your solar energy and use it at night. It also helps you make the most of your generation when you're not home during the day.

SEG payments
Smart Export Guarantee pays you for the electricity you export. Rates vary, but it’s a helpful extra income.

Can I Still Save Without a Battery?

Yes — many homes do. A well-sized solar system will still cut your bills significantly, even without storage.

However, if you:

• Work outside the home during the day,
• Use most energy in the evenings, or
• Want to maximise your self-use and savings…

...then a battery makes a big difference.

The Bottom Line: Solar Pays You Back

If you're spending £80 or more a month on electricity, solar is almost always a smart financial move. You’re replacing rising bills with long-term savings — and adding value to your home.

And the sooner you get started, the sooner you start saving.
