Who calls on us

Two ways of working with us

A solar project rarely stalls on the idea. It stalls on a missing document: the signed calculations the checking authority asks for, the stability file the insurer wants, the technical file the bank reads before committing, the construction drawings the installer has to follow. These are the documents we produce and sign — and we stay on the project through to handover. Structures go further: the ones we calculate, we manufacture.

You are an installer, EPC or integrator

You have the project. What you are missing is the signed design calculation report, the insurer file or the roof structure check that unblocks approval.

  • Structural design calculation reports signed by the engineer
  • Check of an existing roof structure before installation
  • FM Global stability files for the site's insurer
  • DC/AC electrical engineering, grid connection and protections
  • Native files that can be passed to your third-party inspection body

You are a project owner

You are considering a solar investment, or you are looking to get your energy bill under control. We frame the project, we write the tender, then we follow the site through to handover.

  • Feasibility study and production estimate
  • Business case: CAPEX, savings, payback time
  • Comparison of set-ups: direct investment, PPA, third-party financing
  • Tender pack: specification, bill of quantities, comparison of the bids received
  • Financing file: technical documents and yield figures for the bank
  • Site supervision, commissioning, handover and clearing of snags
  • Energy audit and ranked action plan

Our services

Three fields, one principle: everything is calculated

Every deliverable rests on a traceable model and a named standard. The native files can be passed on for independent checking. Four of these calculations also run in your browser, on average assumptions: solar yield, solar carports, PV module comparator and inverter configurator.

FIELD 01

Photovoltaic engineering

From layout to the construction file, on the electrical side as on the structural side.

  • PV electrical engineeringDC/AC sizing, grid connection, protections, earthing, single-line diagram
  • PV structural engineeringBallasted tables, frames on roof structures, carports, ground-mounted structures — NV65, CM66, Eurocodes
  • Roof structure checkCan your roof take the PV array? Full model, ULS/SLS verdict
FIELD 02

Energy and carbon performance

Measure, understand, then rank the measures that pay.

  • Energy auditMetering, modelling, an action plan costed in savings, and putting the financing together
  • Carbon footprintCradle-to-gate product footprint (A1–A3), ISO 14040 / 14044 principles, scope set out
  • Power qualityCos φ correction, harmonic filters, management of energy-hungry loads
FIELD 03

Project support

From framing to handover: the tender, the comparison of bids, the clearing of snags.

  • Feasibility and business caseInstallable capacity, yield, CAPEX, ROI, comparison of contractual set-ups
  • Tender documentsTechnical specification, bill of quantities, response template, criteria for comparing bids
  • Technical monitoringReview of shop drawings, site visits, commissioning, handover and clearing of reservations
Insurer requirement

Is your insurer holding up the installation?

Insurers of industrial sites require justification of the wind resistance of equipment added on the roof, to the FM Global standard — DS 1-15 for photovoltaic structures. Without this file: reservations at the risk survey, blocking recommendations, premium loadings — and a weakened claim in the event of storm damage.

We produce this file in the format the loss prevention engineer expects: pressure calculations by roof zone, uplift, sliding and overturning forces, sizing of the ballast or the anchors, then compliance requirement by requirement. We remain available to answer your insurer directly.

Projects

Studies delivered on real sites in Morocco

Banking, industry, public facilities, education — more than 50 PV structural studies delivered, on their own or alongside our EPC partners. Our clients' names are disclosed only with their agreement.

Carports · 3 cities
Oujda · Laâyoune · Tangier

Solar carports

Design of the frames, sizing of columns and beams, foundation pads and shop drawings — three sites with very different wind exposures.

Car park, industrial site, public facility

PV tables · Roof
Structure designed by JOTUNHEIM

SteadyRidge ballasted tables

Frame, feet, spacings and ballast distribution calculated and then manufactured: from the NV65 / CM66 report to on-site assembly, with no break between design and execution.

Flat roofs and technical stations

Metering · EMS
Municipal swimming pool · Laâyoune

EMS cabinet and measurement units

Consumption monitoring of a public facility: metering, connection of the measurement units and data feed for energy management.

Local authority

Hybrid · Storage
24 kWp · 30 kWh of storage

Hybrid solar installation

Sizing of the generation / storage pair, electrical architecture and battery integration for a site with a constrained supply.

Self-consumption and backup

Solar carports

Our own carports, calculated then manufactured

We have developed our own designs, installed on industrial sites and public car parks in Morocco. Depending on how far along your project is, we either take up the calculations of the carport you have chosen, or we adapt and deliver ours. The carport simulator measures what yours would produce, from your own outline.

Before you commit

A first opinion before any commitment

Tell us about your situation. We will tell you whether there is something to address, what it is, and what study it calls for.

  • We pin down the real need behind the request
  • We identify the structural and insurance constraints to anticipate
  • We point you to the financing programmes you can draw on (GEFF, SR500)
  • We tell you the scope of the study and the documents it assumes
Send my request

What the first conversation leaves you with

The matter named, the study it calls for, and the list of documents to gather.

An assignment then begins with a written scope: what it covers, what it produces, and what it expects from your side.

EPC partners

We regularly carry out studies alongside Moroccan installers and integrators.
