The Solitek SOLID Semi-Clear Frameless series panels are unique, glass-glass modules designed for architectural applications where aesthetics and functionality must go hand in hand. Thanks to the semi-transparent, frameless design, these modules are ideally suited for integration into buildings (BIPV) as pergolas, terrace awnings, glazed facades, or rooflights. The use of N-type TOPCon bifacial solar cells allows for energy generation from both sides of the panel, increasing energy yield without the need for additional system expansion. The glass-glass, frameless design eliminates the problem of dirt and moisture accumulation in the frame corners, resulting in lower maintenance costs and improved self-cleaning properties. The module features a prestigious DIBt certification, one of the few on the market, confirming its safety for building applications. The entire product is covered by a 30-year product warranty, making this series an attractive choice for investors seeking solutions that combine design, durability, and high performance.

About the SOLID Semi-Clear Frameless series

6 answered

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

Are Solitek SOLID Semi-Clear Frameless panels suitable for building integration - for example, as a patio canopy or pergola?
Yes, the SOLID Semi-Clear Frameless series is designed specifically for BIPV applications. The semi-transparent, frameless glass-glass construction allows partial light transmission, making the modules ideal for patio canopies, pergola roofing, curtain-wall facades, and skylight elements. The clean aesthetic means the panel becomes an architectural feature rather than a retrofitted addition.
What warranty does the Solitek SOLID Semi-Clear Frameless series carry?
Solitek provides a 30-year product warranty and a 30-year power output warranty on the SOLID Semi-Clear Frameless series. This is among the longest combined warranty packages available in the photovoltaic market, making it a low-risk choice for long-horizon architectural and commercial investment projects.
What advantage does bifacial TOPCon cell technology offer in the Solitek SOLID Semi-Clear Frameless, and does it actually boost energy yield?
The N-type TOPCon bifacial cells harvest irradiance from both the front and rear sides of the module. In BIPV installations such as glass roofs, light that passes through the semi-transparent layer and reflects off interior surfaces can further increase yield without adding extra modules. N-type TOPCon cells also exhibit lower long-term degradation rates compared to standard PERC technology, improving LCOE over the panel's lifetime.
Does the frameless glass-glass design of the Solitek SOLID Semi-Clear Frameless require more maintenance than conventional framed modules?
Quite the opposite - eliminating the aluminum frame removes the corners and channels where dirt, leaves, and moisture accumulate. The smooth glass-to-glass edge allows rainwater to run off cleanly, reducing cleaning frequency. Maintenance costs are therefore typically lower than for framed modules, which is especially valuable for hard-to-reach installations such as facades and overhead glazing.
What is the DIBt certificate and why does it matter for the Solitek SOLID Semi-Clear Frameless panels?
DIBt (Deutsches Institut für Bautechnik - German Institute for Construction Technology) is a prestigious approval confirming that a product meets the structural safety requirements for use in buildings under German and EU construction standards. Holding a DIBt certificate means the Solitek SOLID Semi-Clear Frameless modules have passed rigorous mechanical and safety testing - a critical requirement for BIPV projects where building permits and load-bearing compliance are mandatory.
What is the maximum power output of the Solitek SOLID Semi-Clear Frameless panel and where is it manufactured?
The peak power output of the SOLID Semi-Clear Frameless series reaches 455 Wp. Solitek is a Lithuanian manufacturer headquartered in Lithuania, specializing in premium and architecturally oriented photovoltaic modules. European production and headquarters simplify access to technical support, warranty claims, and regulatory documentation for EU-based projects.
