Monocrystalline vs polycrystalline panels

The difference between mono and poly solar panels and what usually fits best.

On a limited roof we often pick mono for yield per m². On a large roof poly can work well too. We look at your roof, shading and usage.

Both panel types convert sunlight into power. The main differences are efficiency, appearance and price per panel.

Monocrystalline

Pros

  • +Usually slightly higher yield per m²
  • +Uniform dark look
  • +Common on new installations

Cons

  • -Often more expensive per panel
  • -Smaller real-world gap if roof space is limited

Polycrystalline

Pros

  • +Often lower price per panel
  • +Proven technology
  • +Good yield on spacious roofs

Cons

  • -Lower yield per m² than mono
  • -Bluer, mixed cell appearance

Verdict

On a limited roof we often pick mono for yield per m². On a large roof poly can work well too. We look at your roof, shading and usage.

Frequently asked questions

For most roofs monocrystalline is the logical choice, thanks to higher yield per square metre. On a spacious roof poly can work well at a lower price per panel.
Mono looks uniformly dark, poly has a bluer, mottled colour. Many people find mono looks sleeker.
With limited space mono often pays, because you generate more per panel. You get more from the same square metres.

Which is better: monocrystalline or polycrystalline?

For most roofs monocrystalline is the logical choice, thanks to higher yield per square metre. On a spacious roof poly can work well at a lower price per panel.

Can you see the difference on your roof?
