The SOLID Black Frameless series comprises aesthetically pleasing and technologically advanced photovoltaic panels that combine a full black design with exceptional durability and performance. Thanks to the glass-to-glass frameless design, the panels are naturally self-cleaning - the absence of a frame eliminates dirt and moss buildup, resulting in lower maintenance costs and a longer lifespan for the installation. The use of N-type TOPCon bifacial solar cells allows for capturing light from both the front and the reflected light from the ground, increasing energy production compared to traditional monofacial panels. The series is characterized by exceptionally high mechanical strength - it can withstand extreme loads from snow and wind, and it has a Class 4 hail resistance certification. It also has DIBt certification, which allows for installation on building facades and glazed roofs. The panels are manufactured entirely using renewable energy and have a Cradle to Cradle GOLD certification, making them an ideal choice for investors focused on ESG and sustainable construction. This is a solution for demanding residential and commercial installations, where modern aesthetics combine with a 30-year product warranty.

Common questions

6 answered
What does bifacial mean for the Solitek SOLID Black Frameless panels, and do they really generate more energy?
Yes — the SOLID Black Frameless series uses N-type TOPCon bifacial cells, meaning the panel generates electricity from both direct sunlight on the front and reflected light on the rear, such as from a light-colored roof, ground, or snow. The effect is most pronounced on high-albedo mounting surfaces and can translate into a double-digit percentage yield gain compared to conventional single-sided panels.
What warranty comes with the Solitek SOLID Black Frameless solar panels, and what exactly does it cover?
The SOLID Black Frameless series carries a 30-year product warranty and a 30-year power output warranty. The product warranty covers physical and material defects, while the power warranty guarantees the panel will retain a specified percentage of its original efficiency throughout the coverage period. This places the series among the longest warranty standards available in the PV market.
Can SOLID Black Frameless panels be installed on building facades or overhead glazing?
Yes — the SOLID Black Frameless series holds DIBt certification, the official approval required for facade and overhead glazing installations. It is one of very few panel series worldwide to carry this certificate. The glass-glass construction using 3.2+3.2 mm tempered glass and a static mechanical load rating of up to 10,500 Pa meets the stringent requirements of building-integrated photovoltaics (BIPV).
Do frameless SOLID Black Frameless panels require frequent cleaning?
No — the frameless glass-glass design makes the SOLID Black Frameless naturally self-cleaning. In conventional framed panels, the aluminum frame lip traps dirt, moss, and debris along the edges. Without a frame, rainwater flows freely across the entire panel surface, washing contaminants away. In practice, this means fewer service interventions and lower long-term operating costs over the life of the system.
How does the Solitek SOLID Black Frameless hold up against hail and extreme weather conditions?
The SOLID Black Frameless series is certified to hail resistance class 4, meaning it withstands ice balls up to 40 mm in diameter. It also handles extreme snow and wind loads, with a static mechanical load tolerance of 10,500 Pa. The dual-layer 3.2+3.2 mm tempered glass delivers fire resistance class B, which is critical for building-integrated PV applications.
What sets the Solitek SOLID Black Frameless apart in terms of sustainability and ESG certifications?
The SOLID Black Frameless panels are certified Cradle to Cradle GOLD — one of the most rigorous eco-certifications, confirming circular design and safe recyclability. The entire manufacturing process runs on 100% renewable energy at SoliTek's factory in Lithuania. This makes the series especially attractive for investors pursuing ESG targets and developers seeking BREEAM or LEED credits.
