Read Full Story →How the calculator works
You enter your annual electricity use in kWh, your unit rate in pence, your property type, postcode, roof orientation, shading and roof tile type, and choose any extras such as a battery, and the calculator prices a system of 455W panels. The price is built up from CRG Direct's own supply and installation costs for the panels, roof fixings, electrical kit, inverter, labour and certification. Where Google's Solar API has satellite data for your roof, expected generation comes from it; otherwise it is estimated from your roof's orientation, shading and system size. Savings assume the electricity you use at home saves you your unit rate, and exported electricity earns 12p per kWh under the Smart Export Guarantee. It is an estimate, not a quote, and a site survey confirms the exact figures.
For what a system costs across the UK, read how much solar panels cost in the UK. If you are adding storage, see how much a solar battery costs. To see how the price turns into savings, read how long solar panels take to pay for themselves, and to check the panel count the calculator suggests, see how many solar panels you need.
Can I get a solar price estimate without entering my details?
Yes. You can view a rough solar panel and battery cost estimate instantly, with no email address, phone number, or personal details required.
If you'd like more detail, you can choose to enter your details to download a full personalised solar information booklet. This step is optional.
What's included in the full solar report?
If you choose to continue, the downloadable report includes:
- A detailed system recommendation
- Cost and savings breakdown
- Estimated annual generation
- Payback period explanation
- Information on 0% VAT and the Smart Export Guarantee (SEG)
- Clear next steps if you want a formal quote

How much do solar panels cost in the UK?
Most UK homes pay £5,000 to £12,000 for solar panels installed in 2026, depending on system size, roof type and whether you add a battery. Our solar panel cost guide has the prices by system size.
How much can I save with solar panels?
Savings depend on your energy usage, system size, and whether you add a battery. Most UK homes break even in 8 to 11 years: see how long solar panels take to pay for themselves.
Are there government incentives for solar panels?
Yes. Solar installations carry 0% VAT until 31 March 2027, the Smart Export Guarantee pays you for the electricity you export, and ECO4 can fund solar for eligible households. Our solar panel cost guide covers each scheme.
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.

Frequently Asked Questions About Solar Panels & Costs
How long do solar panels take to pay for themselves in the UK?
In most UK homes, solar panels typically pay for themselves in 8–12 years. The exact payback period depends on your energy consumption, electricity rates, system size, and whether you export surplus energy back to the grid.
What savings do solar panels offer?
Over a 25-year lifespan, solar panels can deliver substantial savings, often more than the original cost of the system, through reduced energy bills, Smart Export Guarantee (SEG) payments, and protection against rising electricity costs. Actual savings depend on your usage, generation and energy costs.
How much can the average UK household save with solar panels?
A typical UK home with a 4–6kW solar panel system can save around £900–£1,400 per year on energy bills, depending on usage patterns, tariffs, and system performance.
What affects the solar panel payback period?
The payback period varies based on your energy consumption, current electricity rates and tariffs, system size and installation costs, export payments through the grid, and whether you use battery storage. Our solar panel cost calculator factors these into its calculations to provide a more accurate estimate.
What is the Smart Export Guarantee (SEG)?
The Smart Export Guarantee (SEG) is a UK scheme that requires electricity suppliers to pay homeowners for excess solar energy exported to the grid. These payments add to your savings and are included in our solar energy calculator results.
How much can SEG payments increase my savings?
SEG tariff rates vary between suppliers, but higher export rates can significantly improve your savings. Selling excess power back to the grid adds to the savings your system delivers.
How many solar panels do I need?
The number of solar panels you need depends on your energy consumption, electricity usage, and available roof space. The calculator estimates how many panels fit your property and usage goals.
What size solar panel system do I need?
System size is based on annual electricity usage, roof size and orientation, and desired energy savings. The tool helps you explore different system sizes to balance costs, benefits, and budget.
How much roof space do solar panels need?
Most residential solar panels have a footprint of around 1.7m × 1.0m. A typical UK home installs between 8–12 panels, depending on system size and roof layout.
Does my roof need to be south-facing?
A south-facing roof is ideal, but east- and west-facing roofs also work well for many UK homes. The calculator adjusts estimates based on roof direction and daylight data.
Can solar panels be installed on flat roofs?
Yes. Solar panels can be installed on flat roofs using tilted mounting systems that angle panels towards the sun to maximise power generation.
Is VAT still 0% on solar panels?
Yes. Solar panels and battery storage currently benefit from 0% VAT in the UK until March 2027, reducing overall installation costs.
How much extra does a battery add to the cost?
Battery storage can increase upfront costs by roughly £1,500–£6,000, depending on size and capacity. However, batteries can significantly increase self-consumption and long-term savings.
How much does a typical solar panel system cost?
Typical UK installation costs: 3–4 kW system: £5,000–£9,000. 4.5 kW system (3-bed home): ~£7,300. Standard residential system (2026): £5,000–£8,000. Battery storage usually adds £2,500–£4,000.
Are monocrystalline panels worth it?
Monocrystalline panels are more efficient and generate more power per square metre, making them a good fit for limited roof space. They cost more than polycrystalline panels but can improve long-term performance.
How accurate is a solar panel cost calculator?
Solar panel cost calculators provide accurate estimates, not fixed quotes. By entering more detailed information about your home and energy use, you’ll receive a more accurate and tailored estimate.
Can I explore different solar scenarios?
Yes. The calculator allows you to explore different system sizes, costs, and savings scenarios to find the best fit for your home, energy goals, and budget.
Can I download my solar calculator results?
Yes. You can download a PDF report with your results, including costs, potential savings, and system recommendations, which can help when requesting a tailored quote from installers.
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 and typically come with 25–30 year warranties.
Can I add batteries or upgrades later?
Yes. Optional upgrades include solar battery storage, bird protection, hot water diverters, and remote system monitoring. These can be included in your estimate or added later.
