1Sun® - PV module

PRISMA® PV module 1Sun®

  • Standardised roof design - Perfect optics for PRISMA® PVT 4.0
  • High performance - Up to 450 W peak power
  • Durable & safe - 25-year product guarantee
  • Bifacial - Generates electricity from both sides
  • Topcon cells - for maximum electricity yield

The ideal complement to PRISMA® PVT 4.0 - for aesthetic, high-performance solar roofs

With the PRISMA® PV module 1SUN® we offer a customised photovoltaic solution that harmonises perfectly with our PRISMA® PVT 4.0. It is the ideal choice if additional roof space is to be utilised but there is no longer a thermal energy requirement. Visually, the PRISMA® PV module 1SUN® is exactly the same as our PVT collector - creating a consistent, modern design on the roof.

Thanks to its high output and durable design, the PRISMA® PV module 1SUN® is particularly suitable for large photovoltaic projects on residential, industrial and commercial roofs. The PV module is also an attractive solution with maximum profitability for property developers and project developers.

Benefit from a high-performance PV module that can be seamlessly into existing PVT systems can be integrated - for an economical and visually appealing use of space.

PRISMA® 1SUN®
Aesthetic overall solution for your roof

The PRISMA® PV module 1SUN® is the perfect addition for anyone who values performance, quality and design in their roof utilisation. Particularly in large-scale projects, on industrial buildings, in the housing industry or in public construction projects, it is not only the energy yield that counts - the appearance must also be right. The 1SUN® PV module is the ideal solution if there is already a PRISMA® PVT 4.0 system is installed, but additional roof areas are still unused and no more thermal energy is required. The identical design of both modules creates a Homogeneous, high-quality roof appearancethat is also convincing in demanding projects.

Thanks to the bifacial technology the PRISMA® PV module 1SUN® can generate electricity not only from the front, but also from the back. This property is particularly interesting in the case of reflective substrates or elevation, as is often the case with Industrial buildings or Commercial halls is to be found. The additional energy yield further optimises land use.

The module is designed for extreme weather conditions: It can withstand snow loads of up to 5,400 Pa and wind loads up to 4,000 Pa stand. This makes it ideal for use in regions with large amounts of snow or strong winds, for example at Roof surfaces in northern Germany or in the Alpine region.

The robust double-glazed construction makes the module particularly durable and resistant. With a product guarantee of 25 years and a performance guarantee of 30 years ensure maximum investment security - an important argument in favour of Project developers, investors and property developersthat focus on sustainability and long-term returns.

The PRISMA® 1SUN® PV module is compatible with standard mounting systems and is easy to transport and install - this is particularly important for large roof areas in the housing, commercial and municipal sectors an advantage.

Whether Residential complexes, industrial halls, logistics centres, public buildings or roof renovations in existing buildings - The PRISMA® PV module 1SUN® adapts flexibly to the most diverse requirements and ensures a clean, consistent roof appearance everywhere.
