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. ## Notable figures - Efficiency of 22.6% matches the \*\*TOPCon 450-500W\*\* median - At 225.8 W/m² power density, roof space requirements are typical for \*\*TOPCon 450-500W\*\* panels - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 450-500W\*\* median - At 33.0 kg (9.0 kg above \*\*TOPCon 450-500W\*\* median of 24.0 kg), requires checking roof load capacity - #3942 for efficiency, #6152 for temperature performance out of 14129 panels ## Questions ### 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. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/SOLID-Semi-Clear-Frameless-B96-455W-EN-493f844ea72a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +40 W, lighter, +2.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +2.1 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +50 W, lighter, +2.1 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +1.9 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +1.9 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +45 W, lighter, +1.9 pp | | [Solitek SOLID Agro Framed 300](https://comparepv.com/panel/ginlong-solis-solid-agro-framed-300) | 300 W | -155 W, heavier, -7.6 pp | | [Solitek SOLID Agro Frameless 300](https://comparepv.com/panel/ginlong-solis-solid-agro-frameless-300) | 300 W | -155 W, -7.7 pp | | [Solitek SOLID Satin 445W](https://comparepv.com/panel/ginlong-solis-solid-satin-445w) | 445 W | -10 W, -0.5 pp | | [Solitek Blackstar Satin 445](https://comparepv.com/panel/ginlong-solis-blackstar-satin-445) | 445 W | -10 W, lighter, -0.3 pp | | [Solitek SOLID Semi-Clear Framed 455 W](https://comparepv.com/panel/ginlong-solis-solid-semi-clear-framed-455-w) | 455 W | Heavier | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +2.4 pp | --- Source: https://comparepv.com/panel/solitek-solid-semi-clear-455 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
