The use of **matte, satin-finish glass** eliminates the problem of light reflection, making these panels ideal for locations particularly sensitive to glare - such as airports, highways, acoustic barriers, or military installations. The **TOPCon n-type cell** technology, combined with the glass-glass construction, guarantees high efficiency and exceptional durability throughout the lifespan of the installation. The bifacial design of the modules allows for additional energy generation from reflected radiation, increasing energy yield without the need to expand the system. A key innovation is the **patented Solrif mounting system** - an aluminum structure that integrates the panel directly with the roof and replaces traditional roofing materials. This 2-in-1 solution combines the function of a weatherproof roof with a high-performance solar power plant, reducing installation costs and project completion time. The panels have a Fire Class A certification, are resistant to ammonia and salt fog, and **30-year product and performance warranty**, making them the ideal choice for demanding commercial, architectural, and infrastructure projects. ## Notable figures - At 21.5% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - Power density of 207.3 W/m² is 12.8 W/m² below \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - needs more roof space - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - Weight of 33.5 kg is 11.5 kg above \*\*TOPCon 400-450W\*\* median (22.0 kg) - verify structural support - Ranked #7887 out of 14129 panels for efficiency in the database ## Questions ### How does the satin anti-glare glass in SoliTek SOLID Solrif Anti-Glare panels work, and does this property fade over time? The matte effect is created solely through a special surface treatment of the glass itself, with no additional coatings or films applied. This reduces reflected luminance to below 3,600 cd/m² compared to over 10,000 cd/m² for standard panels. Because the property is inherent to the glass structure, it does not degrade over time due to UV exposure, rain, or temperature fluctuations. ### How does the patented Solrif mounting system work, and does it truly replace conventional roofing materials? The Solrif system is an aluminum mounting solution developed by Swiss company Ernst Schweizer. Modules integrate directly into the roof slope, forming a weathertight layer instead of conventional tiles or sheet metal. This 2-in-1 approach eliminates the need for a separate roofing material, reduces installation time, and lowers overall project costs. Installation requires a certified Solrif-trained contractor. ### Does the Anti-Glare satin glass reduce the peak power output of SOLID Solrif panels compared to a standard glass version? The power loss is minimal - approximately 2.3% relative to the clear-glass variant. The SOLID Solrif Anti-Glare series still delivers up to 425 Wp, fully competitive within the premium rooftop module segment. N-type TOPCon cell technology with a low temperature coefficient of -0.30%/°C further limits output losses on hot summer days. ### Do the bifacial TOPCon cells in the SOLID Solrif Anti-Glare series genuinely increase energy yield, and by how much? Yes. The bifacial design allows modules to capture irradiance reflected from the roof, ground, or surroundings via the rear cell surface. Real-world yield gain depends on substrate albedo and installation tilt, typically ranging from 5% to 15% compared to a monofacial module. In Solrif in-roof installations where the rear glass faces the interior of the roof structure, the bifacial gain is reduced and should be accounted for in energy simulations. ### What warranty comes with SoliTek SOLID Solrif Anti-Glare panels and what does it cover? SoliTek provides a 30-year product warranty covering material and workmanship defects, alongside a 30-year power output warranty. The modules carry Fire Class A certification and are rated for ammonia and salt mist resistance, with an IP68-rated junction box. The warranty is issued by the manufacturer headquartered in Lithuania, operating across the European market. ### What types of projects are SoliTek SOLID Solrif Anti-Glare panels designed for - are they only for airports and highways? The series targets any glare-sensitive location: airport clearance zones, motorway corridors, noise barriers, military facilities, and heritage or architecturally prominent buildings where standard reflective panels would not receive planning approval. It also suits commercial rooftop installations on pitched roofs where visual neutrality and aesthetics are a primary client requirement. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Rev20251006_Solid_Solrif_Anti-Glare_425W_compressed-51e699a673ab.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | Lighter, +2.5 pp, +10 yr warranty | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | +40 W, lighter, +2.3 pp | | [JA Solar JAT54S40-475/LR](https://comparepv.com/panel/ja-solar-jat54s40-475-lr) | 475 W | +50 W, lighter, +2.3 pp | | [Tongwei TWMNH-48HW475](https://comparepv.com/panel/tongwei-solar-twmnh-48hw475) | 475 W | +50 W, lighter, +2.3 pp | | [Astronergy CHSM48RN(DG)/F-BH-475](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-f-bh-475) | 475 W | +50 W, lighter, +2.3 pp | | [AIKO AIKO-A475-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a475-mce54mw) | 475 W | +50 W, lighter, +2.3 pp | | [AIKO AIKO-A475-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a475-mah54mw) | 475 W | +50 W, lighter, +2.3 pp | | [Solitek SOLID Solrif Terracotta Orange 285W](https://comparepv.com/panel/ginlong-solis-solid-solrif-terracotta-orange-285w) | 285 W | -140 W, -7.1 pp | | [Solitek SOLID Solrif Transparent 290](https://comparepv.com/panel/ginlong-solis-solid-solrif-transparent-290) | 290 W | -135 W, -6.8 pp | | [Solitek SOLID Solrif Terracotta Bronze 355](https://comparepv.com/panel/ginlong-solis-solid-solrif-terracotta-bronze-355) | 355 W | -70 W, lighter, -3.5 pp | | [Solitek SOLID Solrif 435](https://comparepv.com/panel/ginlong-solis-solid-solrif-435) | 435 W | +10 W, lighter, +0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +85 W, lighter, +3.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +70 W, lighter, +3.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +80 W, lighter, +3.2 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +80 W, lighter, +3.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +65 W, lighter, +3.0 pp | --- Source: https://comparepv.com/panel/ginlong-solis-solid-solrif-425 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
