How much do monocrystalline solar panels cost?

The exact cost of monocrystalline solar panels will vary depending on the manufacturer and the size of the solar panels. As a rule of thumb, monocrystalline solar panels have their highest price point at about £1 – £1.50 per Watt. Polycrystalline solar panels, on the other hand, have a lower efficiency rating than monocrystalline panels.

Why are solar panels so expensive?

Panel efficiency: The more sunlight a solar panel can convert into electricity per sq metre, the more expensive it will be. Panel number: More solar panels means more materials, which means a higher cost. You can limit the number of panels you need by choosing highly efficient ones (although they may cost more).
