What criteria to consider before installing solar panels?
The installation of solar panels requires a thorough study of several technical and environmental elements to ensure maximum yield and optimal durability.
The orientation and slope of the roof
To effectively capture sunlight, the roof should ideally face south, with a slope between 30° and 45°. These parameters ensure optimal electricity production throughout the year.
Our technicians conduct a personalized study to determine the most advantageous configuration based on your home and the Luxembourg climate conditions.
The available surface area
The power of your installation directly depends on the usable surface area on the roof. The larger the surface, the more panels and production capacity increase.
Avenir Rénovations precisely assesses the feasibility of the project taking into account shading, potential obstacles, and architectural constraints.
The type of roof
Solar panels can be installed on different supports: tiles, slates, flat roofs, or metal trays. Each type of covering requires a specific fixing method.
Our teams ensure a secure installation, perfectly watertight and compliant with current Luxembourg standards.
Regulations for the installation of solar panels in Luxembourg
Before launching your project, certain administrative formalities must be respected. Avenir Rénovations assists you in all these steps to ensure the compliance of your solar installation with Luxembourg rules.
Municipal and urban planning authorizations
The installation of solar panels on a roof or facade may require prior municipal authorization. This depends on the nature of the building, its location, and the type of installation planned.
Our teams take care of checking the regulations in force in your municipality to compile a complete file that complies with local urban planning requirements.
Compliance with architectural rules
For homes located in protected areas or classified buildings, aesthetic rules may apply. The panels must harmoniously integrate into the landscape and not alter the appearance of the building.
Avenir Rénovations works closely with local authorities to ensure that your installation complies with all architectural and visual prescriptions.
Connection to the electrical grid
Any photovoltaic installation connected to the public network must be declared to the network manager. The latter conducts a technical inspection before authorization for commissioning.
Our technicians ensure electrical compliance, the safety of the connection, and coordination with the energy supplier for a hassle-free connection.
Declaration to the environmental administration
Certain projects must be declared to the environmental administration, particularly to benefit from financial aid. This step also allows for monitoring national energy performance.
Avenir Rénovations manages these formalities for you, so that your project is validated and eligible for incentive grants.
