Selfa Bifacial Full Black modules redefine the standards of aesthetics and efficiency in Polish photovoltaics. This series utilizes advanced bifacial energy generation technology, which allows for electricity production not only from direct sunlight but also from light reflected off the ground. It is an ideal solution for investors who do not want to choose between an elegant appearance and maximum yield. Thanks to the glass-glass construction, these panels are characterized by exceptional resistance to degradation caused by atmospheric factors and high mechanical strength. The Full Black finish ensures that the installation blends perfectly with modern architecture, eliminating visible silver structural elements. This series solves the problem of limited installation space, offering higher productivity from the same area compared to single-sided modules. Importantly, as a product from a domestic manufacturer, it provides service security and a long-term warranty, which distinguishes it from Asian competition. These panels are dedicated primarily to demanding individual customers and companies focusing on innovative installations such as carports or photovoltaic fences. By choosing this solution, the user gains n-type technology, which minimizes energy losses at high temperatures, guaranteeing stable system operation for decades.

Common questions

6 answered
What is the warranty on Selfa Bifacial Full Black panels and what does it cover?
The Selfa Bifacial Full Black series comes with a 20-year product warranty and a 30-year linear power output warranty. This means the manufacturer guarantees a specified minimum energy yield over three decades. As a domestic Polish manufacturer, Selfa provides direct after-sales service without routing claims through overseas support centers, significantly reducing response times in the event of a warranty claim.
How does bifacial technology work in the Selfa Full Black series and how much extra energy can it produce?
Bifacial panels generate electricity from both sides: the front side captures direct solar irradiance, while the rear side harvests light reflected from the ground, rooftop, or facade. Depending on the albedo of the surface beneath, the rear-side gain is typically 5-20% compared to a monofacial module of the same area. The 450 Wp Selfa Bifacial Full Black is therefore especially productive in carport installations or on light-colored or gravel surfaces.
How does N-type cell technology differ from older PERC cells and why does it matter in summer?
N-type cells used in the Selfa Bifacial Full Black series have a lower temperature coefficient than standard P-type PERC cells. In practice, on hot summer days when module temperature exceeds 25°C, power losses are smaller than with P-type technology. N-type cells also exhibit very low LID (Light Induced Degradation), resulting in more stable energy production throughout the full 30-year power warranty period.
Are Selfa Bifacial Full Black 450 Wp panels compatible with a pitched roof and standard mounting hardware?
Yes, the Bifacial Full Black series is designed for standard racking systems used on pitched roofs. The glass-glass construction provides high rigidity, which ensures proper clamping by mid and end clamps. However, installers should note that bifacial glass-glass modules are heavier than conventional glass-backsheet panels, so roof load capacity should be verified before installation.
Why choose Selfa as a Polish manufacturer over a cheaper Asian panel?
Selfa manufactures panels in Poland, which means a shorter supply chain and direct warranty service with no intermediaries. In the event of a defect or claim, there is no risk of communication difficulties or multi-week delays waiting for a decision from an overseas support center. For a residential or commercial investor, this translates into genuine protection of the investment for the full 30-year power warranty term, without the risk of a European distributor shutting down.
What non-standard applications are Selfa Bifacial Full Black panels suited for?
Thanks to the Full Black aesthetic (no visible silver frame elements) and glass-glass construction, this series excels in carport installations, terrace canopies, and photovoltaic fence systems. Bifacial energy generation is an additional advantage here, since light reflected from a light-colored parking surface or walkway reaches the rear of the module. Selfa targets this series at demanding residential customers and businesses seeking solutions that combine premium aesthetics with maximum energy yield.
