This is an estimate, not a quote. It tells you whether solar is worth it at your home. For a final figure, ask an installer.

What next?

  1. Have your roof checkedAn installer confirms shading, structure and panel placement.
  2. Compare at least three quotesThis estimate assumes 11 MAD/Wp installed; a quote far above that deserves a question.
  3. Declare the installationLaw 82-21: under 11 kW, a simple declaration is enough to produce and use your own power.

Why this tool

Morocco has some of the best sunshine in the world, yet home solar remains rare. The main reason: nobody knows how much it would really earn at their own home. This tool answers that question, free and without sign-up.

How it is calculated

PVGIS v5.2 output (European Commission) at your coordinates, for the tilt and orientation you choose. Savings on the 2025 ONEE residential tariff, removing the most expensive tranches first. Roof: OpenStreetMap outline or your own drawing.

What is not taken into account

Shade from neighbouring trees and buildings, the roof's condition and your installer's prices. This is an estimate to help you decide, not a quote.
