Solar thermal and photovoltaic systems in Morocco: legal framework and site checks

Solar installations on Moroccan buildings are framed by laws rather than mandatory product standards. Law 13-09 on renewable energy governs electricity produced from renewable sources, including grid-connected photovoltaic systems. Law 47-09 on energy efficiency is the legal basis of the RTCM thermal regulation (Decree No. 2-13-874) and of appliance performance requirements under Decree No. 2-20-716. The few standards listed for this package, on solar and light properties of glazing and on the calculation of solar thermal systems, are homologated. A voluntary sustainable construction label is being rolled out and may interest clients who ask for it.

Scope

The page covers solar water heaters (thermosiphon or pumped), their collectors, tanks and backup heating, and photovoltaic installations on roofs or shading structures with their inverters, protective devices and, where used, batteries.

It begins at detailed design, when roof space, orientation, structural loads and pipe or cable routes are reserved, and ends with commissioning and the handover of operating instructions. Hot water distribution belongs to plumbing and the main electrical board to the electrical package.

Materials and documents to request

MaterialStandardsSupporting documentsBasis
Solar water heater (collectors and tank)Décret n° 2-20-716 du 25/03/2021Manufacturer's technical documentation, performance data and installation guide; backup heater conforming to its own standard.Specification (CPS) requirement
Photovoltaic panels, inverter and protectionsLoi n° 13-09Data sheets of panels and inverter, single-line diagram with protections and earthing, approved by the electrical engineer.Specification (CPS) requirement
Roof fixings and supports—Fixing details checked by the structural engineer; waterproofing penetrations detailed and accepted by the waterproofing contractor.Good practice

Who does what

PartyRole
Client (owner)Decides on the solar options, handles any grid connection procedure and keeps the maintenance instructions.
ArchitectIntegrates panels and tanks on the roof, checks their visual impact and urban planning rules, and coordinates with waterproofing.
Structural engineerChecks that the roof can carry the panels and full water tanks, including wind effects.
Electrical engineerDesigns the photovoltaic system, its protections and its connection to the building's installation.
Solar installerInstalls, fills and commissions the systems, and demonstrates their operation to the user.

Inspection milestones

  1. Detailed design (APD), calculation notes and consultants' drawings approved Good practice
    Roof area, orientation, loads and routes reserved for solar equipment in the detailed design.
  2. Building services drawings Specification (CPS) requirement
    Solar drawings issued: collector and panel layout, hydraulic and electrical diagrams, fixing details.
    Standards to check at this milestone: NM 06.6.071
  3. Roof waterproofing tested Good practice
    Supports and penetrations prepared before or with the roof waterproofing, never by drilling a finished membrane.
  4. Equipment installed and tested Specification (CPS) requirement
    Solar water circuit filled and running, backup heater working, photovoltaic production and protections tested.
    Standards to check at this milestone: NM 06.6.071

Common non-conformities and follow-up

FindingAction
Panel supports fixed through the roof membrane after waterproofing.Repair of each penetration by the waterproofing contractor under its own guarantee procedure, and redesign of the supports if needed.
Water tank placed on a roof slab not checked for its weight.Emptying of the tank and structural check before it is filled again.
Inverter installed without the protections shown on the diagram.Installation of the missing protections and a new commissioning test.

Frequently asked questions

Is a solar water heater mandatory in Morocco?

The catalogue shows no general obligation. The RTCM and energy efficiency law encourage efficient solutions, and some project specifications require it.

Can I connect my solar panels to the grid?

Law 13-09 provides the framework for renewable electricity. Connection conditions depend on the distributor and the current procedure; check them before ordering the equipment.

Does the roof need to be checked?

Yes. A full solar tank is heavy and panels are exposed to wind; the structural engineer confirms the loads and fixing method.

What should I receive at the end?

The diagrams, data sheets, commissioning report and maintenance instructions for the solar heater and the photovoltaic system.
