Viridian Clearline Fusion PV16 M10 High Performance Dual Glass All Black 445W Solar Panel

Viridian Clearline Fusion PV16 M10 High Performance Dual Glass All Black 445W Solar Panel

The Viridian Clearline Fusion PV16-445AG-M10 is the UK's leading Building-Integrated PV (BIPV) panel, designed to replace the roof covering entirely rather than sit on top of it. N-Type TOPCon cells in a dual glass laminate deliver 23.6% module efficiency and 445W peak output — nearly 10% more power from the same M10 kit footprint than the previous 405W model. Certified to the highest UK fire rating (BROOF T1 & T4, EN 13501-5), holding a BBA Certificate, and dual-listed on MCS005 and MCS012, it is the benchmark in-roof solar solution for new-build, retrofit, social housing, and design-sensitive projects.

Installer Requirement: Must be installed by an MCS-accredited installer competent in roofing works. This is an in-roof BIPV system installed during the normal roofing programme — knowledge of tile/slate interfaces and flashing details is required. Listed on both MCS005 and MCS012. M10 roofing kits carry BBA Certificate No. 0032.
Critical Compatibility: This is not an on-roof panel — it requires Viridian M10 roofing kits and is incompatible with standard solar rails. Max system voltage is 1000V DC — check inverter input. Connectors: Stäubli MC4. Design with the Viridian Fusion Configurator at fusionconfigurator.com.
~10% More Power, Same Kit: The 445AG delivers 445W versus 405W from the same M10 footprint — nearly 10% more output per m². All existing M10 roofing kit inventory is fully compatible, making this a straightforward upgrade for existing Clearline installers.
Key Features & Technology
Neutral Axis Dual Glass

Glass-glass encapsulation places cells at the neutral axis of the laminate — where bending stress is zero — so wind and snow loads impart no mechanical stress to the cells. Glass is also far less gas-permeable than polymer backsheets, dramatically cutting oxidation-driven degradation over the panel's lifetime.

N-Type TOPCon — 23.6% Efficiency

N-Type TOPCon half-cut cells reach 23.6% module efficiency — among the highest of any UK-certified BIPV module. TOPCon minimises recombination losses and resists LID, producing near-rated power from day one with lower long-term decline than P-Type cells.

Highest UK Fire Rating — BROOF T4

Achieves BROOF(T1) and BROOF(T4) under EN 13501-5 — the maximum classification for roofing materials in the UK. Unlike competitors that rely on Extended Application calculations, Viridian holds this rating via direct independent fire testing of the complete panel-and-kit system.

BBA Certified · NHBC Compliant

Holds BBA Certificate No. 0032 — the only BIPV product with third-party NHBC durability accreditation. Essential for new-build, social housing, and zero-bills home developments where warranty sign-off, building control, and NHBC approval all require independently certified structural performance.

In-Roof Rapid Install — <45 Min/kWp

Fitted during the normal roofing programme by the roofing contractor — under 45 minutes per kWp consistently achieved. Compatible with the widest range of UK slate and tile types. Portrait and landscape orientation both supported, giving designers flexible array configurations.

Flush All-Black Roofline Aesthetic

No visible frames, rails, or fixings — the full-black panel integrates flush with the roofline, indistinguishable from premium slate at street level. Passes planning scrutiny more readily in conservation areas, AONB locations, and design-sensitive developments where raised on-roof systems may be refused.

Frequently Asked Questions
How does Clearline Fusion differ from a conventional on-roof solar panel?
A standard on-roof panel sits on top of the existing roof covering via rails and clamps. Clearline Fusion replaces the roof covering entirely — the panels are the roof. They are installed by the roofing contractor during the normal roofing programme using purpose-designed flashings and brackets, resulting in a frameless, flush roofline with no visible fixings, simpler planning approval, and a single contractor responsible for both the roof and the solar installation.
Can the PV16-445AG-M10 be fitted to an existing roof?
Yes — for retrofit, a section is stripped back to the rafters and re-roofed with the Clearline Fusion system. It suits situations where the roof is already being replaced or overhauled. Compatible with pitches between 30° and 60° and a wide range of UK slate and tile types. Use the Viridian Fusion Configurator at fusionconfigurator.com to design the layout and generate a kit list.
Why is the maximum system voltage only 1000V DC?
As a BIPV product certified to UK roofing standards, the 445AG-M10 operates at a maximum of 1000V DC — compatible with most residential and small commercial inverters. It means 1500V inverters cannot operate at their full string voltage capability with this panel. Always verify that your inverter's MPPT input voltage range and maximum open-circuit voltage fall within 1000V DC when calculating string lengths.
Why does the BROOF(T4) fire rating matter for UK projects?
Test 4 (T4) of EN 13501-5 is the relevant UK fire test for building-integrated solar panels, and BROOF(T4) is the highest rating achievable. Viridian holds this via direct fire testing of the complete panel-and-mounting-kit system — not through the Extended Application extrapolation method used by many competitors. This gives building control officers, NHBC surveyors, planners, and insurers full confidence in the certification, which can be the deciding factor in project approval.
