What the Solarwatt Panel vision M 5.0 Style 445Wp is

Solarwatt Panel vision M 5.0 Style 445Wp is a framed glass-glass solar panel in the M 5.0 family, specified here in the Style finish at 445Wp. The M 5.0 series covers more than one power class and more than one finish, so the exact variant matters. In this version, the buyer gets the glass-glass M 5.0 platform with 108 bifacial TOPCon half-cut cells, a black aluminium frame, and the Style-format rear construction that creates a cleaner and more architectural appearance than the printed-back versions.

The 445Wp rating also matters in practice. It places the product at the opening wattage step of the M 5.0 range shown in Solarwatt’s published data. That can be helpful where the project wants the visual and structural qualities of the M 5.0 family but the system design, string planning, or layout logic favours the lowest wattage option in that exact module family.

Who it suits

Panel vision M 5.0 Style 445Wp suits projects where appearance and product build quality both matter. Typical examples include visible residential arrays, design-led roofscapes, bespoke outbuildings, pergolas, canopies, and other structures where a standard opaque module would look heavier than desired. It can also suit buyers who want the M 5.0 family’s stronger published mechanical ratings and 30 year warranty cover, but do not need the 450Wp or 455Wp versions.

The Style variant is particularly relevant where the panel may be seen from below or at shallow viewing angles. In those settings, the more open visual character of the Style finish can become a meaningful part of the overall design rather than a minor product detail.

Key features and practical benefits

• 445Wp nominal output with 22.3% module efficiency.
• 108 bifacial monocrystalline TOPCon half-cut cells.
• Framed glass-glass construction with black aluminium frame.
• Style finish for a more architectural and less visually dense appearance.
• IP68 protection and 1,500V maximum system voltage.
• Pressure load up to 8,100 Pa and suction load up to 2,800 Pa.
• 30 year product warranty and 30 year performance warranty on 90% of nominal power.

The main benefit of this exact version is the combination of styling and specification. A buyer who chooses the Style finish is usually trying to improve how the solar array looks as well as how it performs. The 445Wp variant delivers that visual difference while keeping the M 5.0 glass-glass platform, bifacial TOPCon cells, and stronger published mechanical ratings.

Another practical benefit is control over system design. Not every project needs the highest wattage option in the family. On some roofs, the lower step can make string design and layout easier while still providing high output and a premium build specification. That is where the 445Wp Style variant becomes especially useful.

Technical details that matter in practice

Solarwatt’s M 5.0 Style technical data lists 445Wp, 450Wp, and 455Wp options, with the 445Wp variant delivering 33.0V nominal voltage, 13.5A nominal current, 39.6V open circuit voltage, 14.0A short circuit current, and 22.3% module efficiency. The module uses 108 bifacial monocrystalline high-power TOPCon cells with 182 x 94mm cell dimensions. Overall dimensions are 1,762 x 1,134 x 35mm and the module weighs 24.8kg.

The panel uses a framed glass-glass laminate with anti-reflective tempered front glass, POE encapsulation, and tempered rear glass. Connection details are 2 x 1.2m, 4 mm² cables with Stäubli Electrical MC4-Evo 2 connectors and 3 bypass diodes. Maximum system voltage is 1,500V and protection is rated IP68.

The published mechanical and fire figures are a major part of the M 5.0 proposition. Solarwatt lists pressure load up to 8,100 Pa with test load to 12,150 Pa and suction load up to 2,800 Pa with test load to 4,200 Pa. Fire and building-related ratings include fire class A according to IEC 61730 and UL 790, B-s1, d0 according to EN 13501-1, and BROOF (t1) according to EN 13501-5in the Style datasheet. The module is also listed as class II according to IEC 61140 and qualified to IEC 61215 including LeTID and IEC 61730.

Installation and fitment considerations

Panel vision M 5.0 Style 445Wp uses a conventional framed-panel installation logic despite its more design-led appearance. The 35mm frame and medium-format footprint are well suited to established rail-based mounting systems intended for framed glass-glass modules. The connector format is familiar, the cable length is standard for current PV work, and the panel remains manageable to handle at 24.8kg.

The Style finish creates the main fitment difference. It becomes most valuable on installations where the panel is part of the visual design, including rooflines with high visibility and structures where the module can be seen from below. In those cases, the Style version can create a cleaner-looking result than printed-back alternatives. On a roof where the back of the panel will rarely matter, the choice may come down more heavily to aesthetics from distance and preferred finish.

Why this exact variant may be the right choice

The M 5.0 Style 445Wp is the right choice when the buyer wants the M 5.0 architecture and warranty package in the Style finish but does not require the higher wattage steps. It gives the project a clearly differentiated appearance and still sits in a high-output class for a medium-format panel. That combination can be valuable on premium domestic projects and visible supported structures where design and specification both have to carry weight.

Compared with the 450Wp Black version, the 445Wp Style panel trades some nominal output for a more open visual presentation. Compared with the 455Wp Pure version, it favours architectural styling over the lighter, more traditional silver-frame look. The exact right choice depends on the project brief, but the Style 445Wp variant is the version for buyers who see presentation as a real product attribute rather than a secondary preference.
