How the Solar Panel Cost Calculator Works
01
HOW IT WORKS
Enter Your Details
Tell us your annual electricity use (kWh), choose your UK region, and add your usable roof area (m²). You can also tweak your unit rate (p/kWh) if you know it.
02
HOW IT WORKS
We Check What Fits
We estimate how many solar panels can fit on your roof (based on typical solar panel size and spacing) and work out the maximum system size (kWp) your roof can support.
03
HOW IT WORKS
We Estimate Your Generation
Using regional solar panel data, the solar panel savings calculator predicts your annual solar output (kWh) for the recommended system size.
04
HOW IT WORKS
We Calculate Your Savings
We model how much of that energy you’re likely to use on-site and multiply it by your unit rate to show monthly and annual bill savings. (Assumptions such as self-consumption are clearly stated in the results.)
05
HOW IT WORKS
Get Your Personalised Plan
Review your estimate, then hit the button to request a free, no-obligation quote. We’ll confirm the figures with a quick survey and tailor the system to your property.

Frequently Asked Questions
How accurate is the Solar Panel Savings Calculator?
Our solar panel savings calculator provides a reliable estimate based on your energy usage, location, and available roof size. It uses average UK solar generation data for each region, so your final quote may vary slightly depending on roof angle, shading, and equipment choice.
What information do I need to use the solar panel savings alculator?
You’ll need your annual electricity usage (kWh), an idea of your usable roof area (m²), and your UK region. Optional: enter your electricity rate (p/kWh) for a more precise savings estimate.
Can the solar panel savings calculator tell me how many solar panels I’ll need?
Yes. The solar panel savings calculator estimates how many solar panels can fit on your roof and how large a system (kWp) you’d need to cover your annual energy use.
Does it include installation costs?
The calculator focuses on savings and performance estimates. Once you request a quote, we’ll provide an accurate installation cost tailored to your property and chosen equipment.
How much do solar panels cost in the UK in 2025?
The average solar panel cost in the UK ranges between £4,000 and £8,000 for a typical 3–4kW system, depending on roof size, panel efficiency, and installation type. Larger systems for commercial or high-energy-use homes may cost more but deliver greater long-term savings.
Why do solar panel costs vary across the UK?
Solar panel costs can differ by region due to variations in labour rates, local installer availability, and property types. Urban areas often have higher installation costs than rural locations, but competition between installers can also lower prices in some regions.
Are solar panel costs in the UK still falling?
Yes, while supply costs fluctuate, the average solar panel cost in the UK has dropped by over 60% in the past decade. Improvements in solar panel efficiency and larger-scale manufacturing continue to make systems more affordable for homeowners and businesses.
How does roof type affect solar panel cost in the UK?
Your roof’s material, pitch, and accessibility all influence installation time and labour costs. For example, slate and flat roofs often require extra mounting equipment, slightly increasing the overall solar panel cost.
Are there government grants to reduce solar panel costs in the UK?
Yes. UK homeowners can benefit from schemes such as the Smart Export Guarantee (SEG), which pays you for excess energy exported back to the grid. Some local councils also offer funding or interest-free loans to help offset solar panel installation costs.
Do solar panel costs include batteries in the UK?
Battery storage systems are usually optional and priced separately. Adding a battery typically increases total solar panel costs in the UK by £2,000–£5,000, but it also boosts your energy independence and potential savings.
