The integrated FIT VOLT panel (active part) is a fundamental component of the SOLROOF system, combining the function of a roof covering and a photovoltaic panel. It is responsible for harnessing solar energy and converting it into electricity. Thanks to the use of monocrystalline PERC cells combined with a steel base in glass-steel technology, the panel is sealed, durable, and resistant to varying weather conditions. FIT VOLT is a modern solution that enables the production of solar energy without the need for installing traditional PV modules.
The modular design of FIT VOLT and FIT panels offers many advantages – it enables easier transport, storage, and significantly speeds up installation, which reduces costs associated with project completion time.
EU Production
Our 2-in-1 steel roof components are manufactured in the European Union at our Slovak production facility, using top-quality materials.
Our facility was established to meet rigorous requirements, earning us ISO 9001 certification. Moreover, thanks to our systematic production process, clients receive a comprehensive SOLROOF solution quickly, often within 3-5 business days.
Fire Protection
The roof covering elements, which are also the surface of the photovoltaic module, do not ignite or melt.
SOLROOF Has Obtained the BROOF (T4) Certificate – the Highest Fire Resistance Class for Roofs in Europe. BROOF (t4) – this is the most rigorous and comprehensive test performed in Europe. It includes a simulation of flame spread with simultaneous wind action, a specified time for fire penetration, and examines roof behavior at different angles of inclination. This scope of testing provides a highly realistic picture of how the roofing behaves in real fire conditions.
The results confirmed that SOLROOF does not ignite, does not allow fire to penetrate inside the building, and maintains the highest level of protection for over 60 minutes.
SOLROOF panels also have a BROOF (t1) certificate, based on tests conducted by an independent research unit, comparing the safety level of SOLROOF BIPV installations and traditional PV installations. It was demonstrated that fire spread on the surface of the FIT VOLT system does not occur throughout the entire test.
EASY LINK
A proprietary solution that makes sheets fit together like never before.
The proprietary solution applied involves cutting the corner of the embossing to avoid overlapping three layers of sheet metal at the connection point. Additionally, the specially shaped profile of the edge embossings enables perfect fitting of sheets without visible longitudinal joints.
BEND LOCK
The latest technology for impeccable roof appearance
A technical solution designed to fold the panel at the eaves section of the roof to conceal and protect the cut edge and eliminate the need for screw mounting. Additionally, the lower BEND LOCK fold is cut at an angle, which facilitates panel guidance and lengthwise connection.
VOLT LINK
Registered as an invention, it takes the form of a durable and flexible bonding agent
Used for connecting PV cells to the steel base of the integrated FIT VOLT photovoltaic panel.
CERTIFICATION
Certificates confirming high quality
FIT VOLT panels have undergone a series of safety and quality tests.
• VDE Quality Certificate – international confirmation of product quality and safety, compliant with rigorous technical and electrical standards of the German VDE institute.
• Environmental Management System Certificate in accordance with ISO 14001
• Production Quality Management Certificate in accordance with ISO 9001
LOW WEIGHT
Lighter panel, easier installation
Thanks to its low weight of 15 kg, the FIT VOLT panel doesn’t overload the structure, and its installation is quick and trouble-free, allowing for mounting cost optimization.
High Sound Insulation
SOLROOF photovoltaic panels are made of steel integrated with monocrystalline cells and tempered glass, providing high sound insulation.

XTREME [XT] is the highest-grade protective coating from ArcelorMittal, setting a new standard for durability and resistance of SOLROOF roofs. Thanks to its advanced multi-layer structure with a thickness of 70 μm, it provides exceptional protection for roof panels against the harshest weather conditions – from intense UV radiation to extreme corrosive environments (e.g., coastal areas with high salinity).
We offer the XTREME [XT] coating in deep black XT 33, a shade that perfectly complements the aesthetics of modern construction and SOLROOF roofing. Combined with low-emission XCarb® steel, it guarantees durability with a reduced environmental impact.
Warranty period: up to 60 years * * Detailed warranty conditions are specified in the warranty card.

The MOLLET [O] technology is based on surface microprofiling,which creates a 3D effect and eliminates height differences between FIT VOLT and FIT panels.
XCarb® series steel comes from more sustainable production processes that reduce CO2 emissions through the use of modern technologies, such as recycling, reduced energy consumption, and the implementation of renewable energy sources. XCarb® offers steel with a sustainable profile, ideal for companies aiming to reduce their carbon footprint.
XCarb® low-carbon steel is produced in electric arc furnaces from 75% recycled materials and using only renewable electricity. The carbon footprint when using XCarb® low-carbon steel is about approx. 62% lower than with standard solutions where the sheet is coated with organic coatings.
Despite the reduction in CO2 emissions, the steel retains its excellent mechanical and strength properties, comparable to traditional steel products.
Estimated CO2 footprint for a 150 m2 roof – For XCarb® low-carbon steel: 712.5 kg CO2 eq.
– For classic sheets coated with organic coatings: 1879.5 kg CO2 eq.
