Solar Panel Prices

Understanding the price for solar panels for your home is one of the first — and most important — steps in deciding whether solar is right for you. On this page, we break down average solar panel prices, what influences the final cost, and how you can secure better value for your home.

What’s the Average Solar Panel Price in the UK?

Solar panel prices in the UK can vary, but they’re far more predictable (and affordable) than many homeowners expect.  In 2025, the average price of a fully installed residential solar panel system in the UK was £7,546¹.

That figure typically includes:

  • Solar panels

  • Inverter

  • Installation and labour

  • Basic system setup and certification

However, this is an average. The exact solar panel price for your home depends on your energy use, roof type, and whether you choose to add battery storage.

Lower equipment costs, improved installation efficiency, and growing demand have all helped reduce solar panel prices UK-wide — making now a strong time to consider installing them.

Why Do Solar Panel Prices Vary?

Not all homes are the same — and neither are solar panel systems. Several factors influence the price of solar panels for your property.

Key factors that affect solar panel prices

  • System size (kW)
    Larger homes with higher electricity use typically need more panels, increasing the overall price.

  • Roof orientation and condition
    South-facing roofs often need fewer panels to generate the same output. Complex roofs can increase installation time.

  • Type of solar panels installed
    Higher-efficiency panels usually cost more upfront but generate more electricity in limited space.

  • Installation complexity
    Roof type, wiring routes, scaffolding, and fittings all affect labour costs.

  • Installer quality and accreditation
    Certified, experienced installers may not be the cheapest — but they offer reliability, warranties, and long-term performance.

  • Battery storage
    Adding a battery increases upfront cost but improves long-term savings and energy independence.

What’s the Price for Solar Panels for Your Home?

When homeowners search for solar panel prices for their home, what they really want to know is simple: how much will it cost me?

As a rough guide:

  • Smaller households with lower energy use need fewer panels

  • Larger households with higher generation benefit from bigger systems 

  • Your roof size and layout play a major role in system design

That’s why online averages can only go so far. The most accurate price for solar panels for your home comes from a tailored assessment that looks at your property, energy use, and goals.
