A key feature of this series is the **matte, anti-reflective Satin coating**, which effectively eliminates glare typical of standard panels. With a luminance level not exceeding 3600 cd/m², the installation does not interfere with the surrounding environment, neighbors, or traffic. The **glass-to-glass** design gives the modules an elegant, minimalist appearance that seamlessly integrates with the roof or facade, while also making them easy to clean of dust and snow. The technology of **monocrystalline bifacial solar cells** allows for energy generation from both sides of the module, increasing energy yield without the need for a larger installation area. The full black aesthetic, combined with the durability of the glass-to-glass construction, makes this series particularly valued in projects where both **performance and visual appeal** are important. The manufacturer offers product and line warranties that exceed industry standards, confirming the long-term reliability of the modules. ## Notable figures - At 22.1% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - At 220.8 W/m² power density, roof space requirements are typical for \*\*TOPCon 400-450W\*\* panels - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - At 33.0 kg (11.0 kg above \*\*TOPCon 400-450W\*\* median of 22.0 kg), requires checking roof load capacity - In the top 44% for efficiency among all TOPCon panels ## Questions ### Will SoliTek SOLID Satin Frameless panels cause glare problems for neighbors or drivers? No. The Satin anti-glare glass limits luminance to under 3,600 cd/m², while standard panels exceed 10,000 cd/m². This eliminates disruptive reflections onto neighboring properties, residential windows, and nearby roads. The series is especially recommended for dense urban areas and buildings situated close to traffic routes or busy intersections. ### What is TOPCon technology and why does it matter in the SOLID Satin Frameless series? TOPCon (Tunnel Oxide Passivated Contact) refers to next-generation n-type cells that deliver higher efficiency and lower long-term power degradation compared to standard PERC cells. In the SOLID Satin Frameless series, this translates to a peak power of 445 Wp and module efficiency of approximately 21.8%. The bifacial cell layout further boosts energy yield by capturing irradiance reflected from the mounting surface. ### What warranty comes with SoliTek SOLID Satin Frameless panels? SoliTek provides a 30-year product warranty and a 30-year linear power warranty. After 30 years, the module retains at least 90% of its rated output. This is among the longest warranty standards in the industry — most manufacturers offer only 10–15 years on the product and 25 years on power output. The expected operational lifetime of the modules reaches up to 50 years. ### Can the frameless glass-glass construction handle heavy snow loads and strong winds? Yes. SOLID Satin Frameless modules are rated for snow loads up to 10,500 Pa and wind loads up to 4,500 Pa. The glass-glass laminate also withstands hail up to 5 cm in diameter. The series carries Fire Class A certification and is resistant to salt mist and ammonia, making it suitable for demanding climate conditions. ### Is the SOLID Satin Frameless series suitable for building-integrated photovoltaics (BIPV) facade applications? Yes — the frameless design and full-black aesthetics make this one of the most frequently specified modules for BIPV projects. The smooth glass-glass surface blends seamlessly with modern facades and flat roofs while facilitating rain run-off and self-cleaning. SoliTek, headquartered in Lithuania, specializes in architectural PV modules. ### How does the SOLID Satin Frameless differ from the framed Satin version? The key difference is the absence of an aluminum frame — the Frameless variant has a cleaner edge profile and is preferred for BIPV and flat-roof applications. The Framed version (available in 35 mm or 40 mm profiles) installs more easily on conventional hook-based racking and is more practical for standard pitched-roof installations. Both variants share the same peak power rating (up to 445 Wp) and identical warranty terms. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/SOLID-Satin-Frameless-B96-445W-EN-b5cdb58a329e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +50 W, lighter, +2.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +45 W, lighter, +2.4 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +45 W, lighter, +2.4 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +40 W, lighter, +2.2 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +40 W, lighter, +2.2 pp | | [Longi Solar LR7-54HJD-495M](https://comparepv.com/panel/longi-lr7-54hjd-495m) | 495 W | Cooler, lighter, +2.2 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +40 W, lighter, +2.2 pp | | [Solitek SOLID Agro Framed 300](https://comparepv.com/panel/ginlong-solis-solid-agro-framed-300) | 300 W | -145 W, heavier, -7.1 pp | | [Solitek SOLID Agro Frameless 300](https://comparepv.com/panel/ginlong-solis-solid-agro-frameless-300) | 300 W | -145 W, -7.2 pp | | [Solitek Blackstar Satin 445](https://comparepv.com/panel/ginlong-solis-blackstar-satin-445) | 445 W | Lighter | | [Solitek SOLID Semi-Clear Framed 455 W](https://comparepv.com/panel/ginlong-solis-solid-semi-clear-framed-455-w) | 455 W | +10 W, heavier, +0.7 pp | | [Solitek SOLID Black Frameless 455](https://comparepv.com/panel/ginlong-solis-solid-black-frameless-455) | 455 W | +10 W, +0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +65 W, lighter, +2.9 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +60 W, lighter, +2.6 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +2.4 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +55 W, lighter, +2.4 pp | --- Source: https://comparepv.com/panel/ginlong-solis-solid-satin-445w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
