Using this information, the calculator estimates:

All estimates are based on UK daylight data, average panel efficiency, roof direction, and your local conditions.

How much do solar panels cost in the UK?
The cost of solar panels depends on system size, roof type, and whether you add battery storage.
Typical UK prices:
- 4kW solar system (average home): £5,000–£6,000 installed
- Solar + battery system: £13,000–£15,500 depending on battery size
Most homes use 8–12 panels, with total costs influenced by panel efficiency, installation complexity, and available roof space.
Finance options are available to help spread the cost.
How much can I save with solar panels?
Savings depend on your energy usage, system size, and whether you add a battery.
Typical UK savings:
- Annual savings: £440–£1,005
- Payback period: 7–9 years for most homes
Examples:
- Smaller homes (1–2 bedrooms): ~6 panels (2.1kW), saving ~£270 per year
- Larger homes (3–4 bedrooms): 10–14 panels, saving £450–£630 per year
Battery storage can increase savings by allowing you to use more of your own solar energy.
Are there government incentives for solar panels?
Yes. UK homeowners may benefit from:
- 0% VAT on solar panel installations until 2027
- Smart Export Guarantee (SEG) payments for exporting excess electricity
- ECO4 / HUG2 grants for eligible low-income households
- Green or interest-free loans from selected lenders
Eligibility depends on your property and circumstances.
What affects the cost and performance of solar panels?
Several factors influence both price and output:
- System size
- Roof orientation and shading
- Panel efficiency
- Installation complexity
- Location and daylight hours
The calculator accounts for these factors to give a realistic estimate rather than a generic figure.
How long does solar panel installation take?
For most homes:
- Installation takes one day
- Planning permission is usually not required
- Systems are tested and connected on the same day
- Panels are low-maintenance with 25–30 year warranties
Can I add batteries or upgrades later?
Yes. Optional upgrades include:
- Solar battery storage
- Bird protection
- Hot water diverters
- Remote system monitoring
These can be included in your estimate or added later.
Why use an online solar calculator first?
Using a calculator lets you:
- Understand likely costs before speaking to an installer
- Check whether solar makes sense for your home
- Avoid unnecessary site visits
- Get clear pricing expectations early
It's a simple way to make an informed decision.
