Thornova 425W Bifacial Solar Panel
The Thornova TS-BBT54-425W is a 425-watt, all-black bifacial solar panel built with high-efficiency N-type monocrystalline cells. Its bifacial design captures sunlight from both the front and rear surfaces, increasing potential energy production when installed above reflective surfaces such as light-coloured roofing, gravel, concrete, or snow.
With a compact 54-cell format, black frame, and transparent black mesh backsheet, this panel delivers a clean appearance for residential, cottage, off-grid, and commercial solar installations. The N-type cell technology provides low degradation, improved low-light performance, and dependable energy production over the panel’s service life.
Bifacial Energy Production
The rear surface can capture reflected sunlight, providing up to 25% additional energy production under suitable installation conditions. Actual bifacial gain depends on mounting height, surface reflectivity, shading, and site layout.
N-Type Mono-crystalline Cells
N-type cells are less susceptible to light-induced degradation than conventional P-type cells. This helps maintain stronger output over time, with up to 10% to 30% greater lifetime energy production compared with standard P-type modules.
Strong Low-Light Performance
The TS-BBT54-425W continues generating power during cloudy, overcast, and lower-light conditions. This makes it well suited for Canadian installations where solar conditions can change considerably throughout the year.
Improved High-Temperature Performance
A low temperature coefficient helps reduce power loss as panel temperatures rise. This allows the module to maintain more consistent production during hot summer conditions while supporting dependable year-round operation.
Built for Canadian Conditions
The panel is certified to withstand wind loads up to 2,400 Pa and snow loads up to 5,400 Pa. Its anodized aluminum frame, tempered glass, and IP68-rated junction box provide protection against demanding outdoor environments.
Long-Term Warranty Coverage
The Thornova TS-BBT54-425W includes a 15-year product warranty and a 30-year linear power output warranty. Annual degradation is limited to 0.40% after the first year, supporting dependable long-term energy production.
