FAQ

There are rooftop-mounted photovoltaic solutions that allow solar panels to be installed on a flat roof without penetrating the waterproofing. Soprasolar systems use, for example, mounting pads welded directly to the waterproofing membrane or lightweight, self-adhesive photovoltaic modules, depending on the chosen solution. The absence of through-penetration fasteners helps preserve the integrity of the flat roof’s waterproofing system. The choice of method depends on the configuration of the building and the roof.

Yes, provided that the condition of the roof and the structure’s ability to support the photovoltaic system are verified beforehand. In renovation projects, an assessment helps evaluate the building’s waterproofing, insulation, and load-bearing capacity. Depending on the characteristics of the existing roof, a photovoltaic system mounted on pedestals or a lightweight solution may be considered. Prior renovation of the roof system may also be necessary.

The choice depends primarily on the roof’s configuration, its waterproofing and insulation system, and the structural load-bearing capacity. Soprasolar offers, among other things, photovoltaic solutions mounted on pedestals using Fix Evo and lightweight, self-adhesive solutions using Flex. For an existing roof, a preliminary assessment helps determine the building’s suitability and guide the selection of the appropriate installation method.

The feasibility of a photovoltaic system depends on several characteristics of the building: roof type, structure, load-bearing capacity, insulation, existing waterproofing, and project-specific constraints. A technical study allows for the assessment of these various factors and the determination of the photovoltaic solution best suited to the roof. This step is particularly important for existing buildings and renovation projects.

Relevant progress has been made with regards to the Energy Pay-Back Time. The time required for the PV module to work off its energy debt is 1 year. Considering a lifespan of 30 years, a PV module will produce around 30 times the amount of energy that was required to build it.

94%, that’s the average reuse rate for crystalline PV modules with an aluminium frame!

Yes. It is necessary to consider and design the future installation of a power station while erecting the building. It is not only true for solar systems but also for numerous work contract lots. Naturally, these works are subjected to insurance requirements and must comply with up-to-date regulations.

The cost of solar electricity production continues to decrease. According to a report from the International Renewable Energy Agency (IRENA), it could even decrease by another 60% by 2025.

It depends on several factors. To provide the best answer, we need to assess if panels can be installed across the entire roof and identify any hindrances or amenities present. Generally, the ratio is 1 kWp per 10 sqm. Please feel free to contact our Sales Managers for more information.

Yes. Renovating a flat roof provides an opportunity to incorporate a solar power system at the same time. It allows you to ensure, right from the start of the renovation, that the structure, insulation, waterproofing, and the future solar power system are compatible. Depending on the condition of the existing roof, various renovation solutions can be considered before installing the solar panels.

The design of a photovoltaic roof must incorporate waterproofing from the outset. Soprasolar solutions, in particular, allow for a rooftop photovoltaic system to be installed without mechanical fasteners that penetrate the waterproofing membrane. Depending on the method used, the mounting brackets can be welded directly to the waterproofing, or the photovoltaic modules can be self-adhesive. The goal is to combine solar power generation with the long-term durability of the roof within a single technical system.

A photovoltaic roof should be designed as an integrated system that combines the building’s structure, insulation, waterproofing, and the photovoltaic system. These various components must be compatible with one another and tailored to the project’s specific characteristics. This holistic approach ensures that the building’s thermal performance and waterproofing are maintained while seamlessly integrating the photovoltaic panels.

Installing a solar system on an industrial building begins with an analysis of its roof: the substrate, structure, insulation, waterproofing, and ability to support the loads associated with the photovoltaic installation. Large flat roof areas, particularly those with steel or concrete decking, can be put to good use with appropriate photovoltaic solutions, even without penetrating the waterproofing. Fire safety requirements and the building’s specific characteristics must also be taken into account.

An existing warehouse can be equipped with photovoltaic panels after the structure and roofing system have been inspected. Depending on the structure’s load-bearing capacity and the condition of its waterproofing, various solutions can be considered, including lightweight photovoltaic systems. For certain warehouses, particularly ICPE-classified buildings, specific fire safety requirements must also be incorporated into the project design.
