Feasibility study at a private home

Why the feasibility study changes everything

A quote without a site visit is a shot in the dark. Surveying the existing setup and analysing actual consumption and access constraints determine the capacity to install — and avoid the two classic mistakes: oversizing or undersizing.

The STEG application, step by step

Preparing the application, submitting it, following its review and then coordinating the grid connection: so many steps that put project owners off. Here is what a complete application contains and the timeframes to expect.

Inspecting an industrial electrical cabinet

Electrical cabinet: the warning signs

Overheating, repeated tripping, illegible labelling, undersized protection devices. Reviewing these points once a year prevents production shutdowns, which cost far more than the inspection.

Electrical work on board: what the marine environment demands

Salt, humidity, vibration and confined spaces: on board, equipment and installation methods have nothing in common with those of a building. Cable glands, hydrocarbon-resistant cables and corrosion protection determine the lifespan of the installation.

Maintaining a solar installation

Dust and sand significantly reduce output, especially in southern Tunisia. Regular cleaning, checking connections and monitoring inverters are usually enough to maintain expected production.

Measuring production on an installation

  • Maintenance

Falling output: the most common causes

A dirty module, a loose connection or a faulty inverter can cost a significant share of production without any warning. Monitoring makes it possible to catch the drift in time.

Electrical installation in an oil & gas area

  • Oil & gas

Hazardous areas: why standard equipment isn’t enough

On an oil or gas site, potentially explosive atmospheres require equipment suited to the area classification, carefully executed equipotential bonding and full traceability of tests.

What solar changes for a business

Workshops, shops and hotels consume mostly during the day, exactly when a solar installation produces the most. It’s the most favourable profile for self-consumption: the energy produced is used on site.

  • Savings

Up to 70% savings: where does that figure come from?

Lower bills, protection against rising tariffs, added building value and long module lifespan. Here is how the real savings break down, and what makes them vary from one site to another.

Solar on a farm

Solar on the farm

Estates and farms have significant electricity needs in broad daylight, often far from the grid. Between self-consumption for buildings and pumping for irrigation, solar finds its most natural ground there.
