Solar Roof Tiles vs Panels: Which Is Cheaper in 2026? (UK)

For most UK homes, standard panels win on price — a typical 4kW–5kW system runs roughly £6,000–£10,000 installed, while a whole-roof solar tile system usually lands between £12,000 and £20,000+. Tiles cost more but look seamless — here’s when each is worth it.

Which is cheaper — solar tiles or panels?

  • Panels are cheaper upfront. A typical 4kW–5kW on-roof system costs around £6,000–£10,000 installed in 2026.
  • Solar roof tiles cost more. A whole-roof integrated (BIPV) system usually runs £12,000–£20,000+, or roughly £250–£500 per m².
  • Panels pay back faster — typically ~7–10 years versus ~12–18 years for tiles.
  • Panels produce more per m². Tiles give roughly 10–15% less output for the same roof area.
  • Tiles win on looks. They make sense on new builds, full re-roofs, or conservation areas where bolt-on panels are restricted.

In short: if your goal is the lowest cost and quickest return, standard solar panels are the clear winner. Solar roof tiles are a premium choice — you pay extra for a near-invisible finish, and they only really make financial sense if you’re already replacing the roof or planning rules rule out conventional panels. Either route, adding a home battery costs a further £3,000–£6,000.

Solar roof tiles vs panels, side by side

The two technologies generate electricity the same way — the difference is how they mount to your roof, what they cost, and how they look. Here’s how they stack up across the factors that matter most.

FactorSolar roof tilesSolar panels

Figures are typical UK 2026 installed costs and will vary with roof size, system specification, and installer. Always compare written quotes.

Which should you choose?

Choose panels if you want the best value

If lowest upfront cost and the quickest payback are your priorities, standard on-roof panels are the smart pick. They’re cheaper per watt, generate more from the same roof area, and usually fall under Permitted Development — so the install is fast and straightforward on an existing home.

Choose tiles if looks come first

If a discreet, seamless roof is non-negotiable — or your property is in a conservation area where bolt-on panels are restricted — solar tiles deliver a near-invisible finish. You pay a premium and wait longer for payback, but the kerb appeal can be worth it.

Tiles win during a re-roof or new build

If you’re already replacing the roof or building from scratch, the maths shifts. Because tiles double as the roof covering, you offset some of the re-roofing cost you’d pay anyway — narrowing the gap with conventional panels.

Add a battery either way

Whichever technology you choose, a home battery lets you store daytime generation for evening use and typically adds £3,000–£6,000. It boosts self-consumption and savings regardless of whether you go for tiles or panels.

Common Questions

It depends on your priorities. Tiles cost roughly double a panel system and pay back more slowly, so on pure economics panels usually win. But if appearance matters — or you’re re-roofing anyway, or live somewhere conventional panels aren’t permitted — the seamless look and integrated roof can justify the premium.
Not quite. For the same roof area, integrated tiles typically produce around 10–15% less than standard panels because of their lower power density and tighter integration with the roof. You can sometimes close the gap by covering more roof area, but that pushes the cost up further.
Both are long-lived. Quality solar panels commonly come with 25-year-plus performance warranties, and integrated solar tiles are designed to match the lifespan of a modern roof. Inverters typically need replacing once during the system’s life regardless of which option you choose.
Standard panels are usually covered by Permitted Development on most homes, though conservation areas, listed buildings, and some new estates have extra restrictions. Solar tiles are normally fitted as part of a re-roof and can be the better route precisely where bolt-on panels are restricted. Always confirm with your local authority before committing.
Yes — batteries work with both tiles and panels and are typically added for £3,000–£6,000. A battery stores daytime generation for evening use, increasing how much of your own solar you actually consume and improving overall savings whichever roof technology you choose.
