The Solitek SOLID Bifacial Full Black series is a unique range of photovoltaic panels that combines the aesthetic of deep black with advanced bifacial technology. Thanks to the glass-glass construction with black backing glass, the modules have a uniform black appearance from both sides - ideal for installations where the appearance is important. The bifacial technology allows for energy generation from both the front and back of the panel, resulting in significantly higher energy yields compared to standard monofacial modules - especially on bright surfaces or rooftops. The series is distinguished by its exceptional durability - the modules withstand extreme loads from snow, wind, and hail, and the A-class fire rating provides additional safety. The manufacturer guarantees a 30-year product warranty while maintaining high performance throughout this period. The prestigious Cradle to Cradle GOLD certificate confirms European, environmentally responsible production standards. The panels are available in both frameless and framed versions, making them an ideal choice for both roof installations and modern BIPV projects - wherever high energy efficiency goes hand in hand with demanding aesthetics.

About the SOLID series Bifacial Full black series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

How much more energy do Solitek SOLID Bifacial Full Black panels produce compared to standard monofacial modules?
Thanks to bifacial technology, Solitek SOLID Bifacial Full Black panels harvest energy from both the front and rear sides of the cell. On reflective surfaces such as light-colored roofing, gravel, or snow, the bifacial gain can reach up to 35% over standard monofacial modules. In typical rooftop installations, the gain usually ranges from 5% to 15%, depending on substrate albedo and tilt angle.
What warranty is offered on Solitek SOLID Bifacial Full Black panels and what does it cover?
Solitek provides an exceptionally long 30-year product warranty covering material and workmanship defects. A separate 30-year power output warranty guarantees the panel will retain at least 90% of its nominal 435 Wp after three decades. This is among the longest warranties available in the PV market and a key differentiator of the SOLID series.
Are Solitek SOLID Full Black panels suitable for pitched roof installations and BIPV projects?
Yes, the Solitek SOLID Bifacial Full Black series is available in both frameless and framed (35 mm) versions, making it an excellent fit for standard pitched roof systems as well as advanced BIPV (Building-Integrated Photovoltaics) applications. The uniformly black appearance on both sides - achieved through the black rear glass in a glass-glass construction - ensures a clean aesthetic even in highly visible locations.
How do Solitek SOLID Bifacial Full Black panels hold up against heavy snow, strong wind, and hail?
SOLID Bifacial Full Black modules carry a Class A fire rating and are engineered to withstand extreme mechanical loads - wind and snow pressure up to 10,500 Pa - as well as hail impact. The rigid glass-glass construction provides exceptional structural integrity. A competitive temperature coefficient of Pmax at -0.3%/°C means minimal power loss during cold winters compared to older PERC technology.
How does the TOPCon cell technology in Solitek SOLID Bifacial Full Black panels differ from older PERC cells?
N-type TOPCon (Tunnel Oxide Passivated Contact) cells deliver approximately 22% module efficiency, noticeably higher than typical PERC cells. TOPCon also exhibits lower recombination losses, stronger resistance to light-induced degradation (LID), and better performance at elevated temperatures. These characteristics are precisely what enables Solitek to back the SOLID series with a 30-year power output warranty.
What does the Cradle to Cradle GOLD certification on Solitek SOLID Full Black panels mean and why does it matter when purchasing?
The Cradle to Cradle GOLD certification confirms that Solitek SOLID panels are manufactured to the highest European environmental standards. The modules are lead- and cadmium-free and 100% recyclable thanks to the glass-glass construction. Solitek's Lithuanian factory is one of the few European PV manufacturers holding this prestigious certification, which matters increasingly for ESG compliance and subsidy programs that favor European-made products.
