The SOLID Bifacial Full Black series from SoliTek is a premium-class photovoltaic panel that combines the aesthetics of a completely black module with advanced bifacial energy generation technology. Thanks to the glass-glass construction - featuring 3.2 mm thick tempered glass on both sides - the modules stand out for their exceptional durability and resistance to extreme weather conditions, including hail up to 50 mm in diameter, strong winds, and snow loads significantly exceeding industry standards. Bifacial technology allows for the absorption of reflected radiation from the ground, which, under favorable conditions, can increase energy yield by up to 35% compared to conventional monofacial modules. The rear glass, coated with a black layer, gives the panel a uniform and discreet appearance - making it the ideal solution for roof-mounted installations requiring high aesthetics, such as single-family homes, residences, or buildings with specific architectural requirements. The series is available in frameless and framed versions, and the Cradle to Cradle GOLD certification confirms its compliance with sustainability principles. A 30-year product warranty with a minimum of 90% performance guarantee is a rare investment protection in the photovoltaic market.

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 does the SoliTek SOLID Bifacial Full Black panel generate compared to a monofacial module?
Thanks to bifacial technology, the SoliTek SOLID Full Black captures light on both the front face and the rear side by absorbing radiation reflected from the ground surface. Under ideal conditions - high-albedo ground cover, optimal tilt angle - the rear glass can contribute up to 35% additional energy yield compared to a conventional 435 W monofacial module. In typical Central European conditions, a realistic bifacial gain ranges from 5% to 15%.
What warranty does the SoliTek SOLID Bifacial Full Black come with and what does it cover?
The manufacturer provides an exceptionally long 30-year product warranty and a 30-year power warranty guaranteeing at least 90% output efficiency throughout that entire period. This is one of the strongest investment guarantees available in the PV market - most competing manufacturers offer a product warranty of 12-15 years and a power warranty of 25 years.
How does the TOPCon cell technology in the SOLID Full Black series compare to standard PERC cells?
TOPCon (Tunnel Oxide Passivated Contact) cells deliver higher conversion efficiency and a lower temperature coefficient (approx. -0.30%/°C) than standard PERC cells. This means less power loss on hot days and better performance under low-irradiance conditions - both factors translate into higher annual energy yield in climates with variable cloud cover typical of Central Europe.
Can the frameless SoliTek SOLID Full Black panel be installed on a typical pitched roof of a single-family home?
The SOLID Bifacial Full Black series is available in both a frameless version and an aluminum-framed version (35 or 40 mm frame). For standard pitched roofs using conventional clamp mounting systems, the framed variant is recommended - frameless modules require a dedicated mounting system compatible with glass-glass construction. The 1767×1160 mm footprint and all-black glass-glass aesthetics pair well with dark ceramic or concrete roof tiles.
How resistant is the SoliTek SOLID Full Black panel to hail, snow loads, and high winds?
The glass-glass construction with 3.2 mm tempered glass on both sides provides certified resistance to hailstones up to 50 mm in diameter. The modules withstand snow and wind loads significantly exceeding IEC industry standards. A Fire Class A rating makes them a safe and durable choice for rooftop installations with the highest reliability requirements.
Does the SoliTek SOLID Bifacial Full Black series carry environmental certifications and are they worth the premium?
Yes. The SOLID Bifacial Full Black series holds Cradle to Cradle GOLD certification - one of the most rigorous sustainability standards for industrial products. It confirms that the Lithuanian manufacturer designs its modules for closed-loop recyclability and minimal environmental impact across the full product lifecycle. For investors pursuing green subsidies or ESG-driven projects, this certification is a meaningful differentiator.
