The system has passed all current tests in various configurations required for construction in such countries, as France, Belgium, the Netherlands, the United Kingdom and the Czech Republic.
GSE IN-ROOF SYSTEM™ is integrated into the roof substructure and therefore becomes part of the roof structure.
According to information from HZS ČR and the management of PAVUS a.s., the GSE IN-ROOF SYSTEM™ must comply with the Czech standard ČSN P 73 0847 – “Fire safety of buildings – photovoltaic systems“, which was published in May 2024.
To meet this standard, the GSE IN-ROOF SYSTEM™ must meet the requirements of the European standard ISO 1716:2018 (ČSN EN ISO 1716 (730883)) – “Testing the reaction of products to fire-determination of combustion heat (caloric value)”.
GSE IN-ROOF SYSTEM™ is patented and one of the most certified integrated roof systems (BIPV) in the European Union. The system has the European classification of Broof (t1), Broof (t2), Broof (t3) a Broof (t4).
In the attached document you will find the results of the test of the standard ISO 1716 carried out in the laboratory of PAVUS a.s., which shows that the main plastic component of the system complies with this standard, is not a combustible material and is suitable for use in the construction of the roof covering and that it corresponds to the fire safety standard.

The PV module is not laid on the bottom surface of the GSE frame, but lies on special racks, so that the air gap is about 4-5 cm between the back of the PV module and the GSE frame, and at least 7-9 cm between the back of the PV modules and the insulating film.
In addition, thanks to the technical holes in the middle of the GSE frames, the ventilation is strengthened throughout the roof structure. You can find a more detailed visualization here here.
These measurements were carried out by GSE Intégration in the central France, during period 2022/2023, in the area of the airblade, between the lower insulating film of the roof substructure and the back of the photovoltaic module.

A low-voltage device that maximizes the amount of energy each solar panel produces and mitigates all types of module mismatch-losses, from manufacturing tolerance to partial shading and aging.
Micro-inverters and performance optimizers are often collectively referred to as” Module-Level Power Electronics ” or MLPE. Micro-inverters are rapidly gaining popularity, especially for residential solar systems.
Micro-inverters tend to be more expensive than string inverters or power optimizers, but their costs are falling as they become more popular. Performance optimizers offer many of the same benefits as micro-inverters, but they tend to be a bit cheaper.
Performance optimizers are often considered a compromise between more expensive micro-inverters and a standard string inverter.
GSEI offers its customers the products of ENPHASE, of which it is officially a distributor.
Wevolt Energy Roof 270 g/m² is a special roofing membrane with high fire resistance designed for use under photovoltaic modules embedded in the roof structure.
