A key feature is the **satin glass** with an extremely low reflection rate - an ideal solution for locations sensitive to glare, such as airports, schools, highways, or military installations, where standard panels cause distracting light reflections. Modules based on **N-type TOPCon bifacial technology** (3.2+3.2 mm TVG glass-glass construction) offer higher thermal stability and slower degradation compared to PERC panels, and a 30-year product and performance warranty is one of the longest standards in the industry. The prestigious **Cradle to Cradle Gold** certification - as the only panel in this class worldwide - confirms that 98% of materials are recyclable, and that the entire production process uses renewable energy. Durability is also confirmed by resistance to hail (Class 5, 50mm diameter), ammonia, salt spray, and snow loads up to 10,500 Pa. The patented **Solrif D** mounting system from Ernst Schweizer AG integrates the panel directly with the roof structure, eliminating the need for separate flashing or gutters. The series is primarily intended for premium investments - commercial buildings, public facilities, and architectural projects that require aesthetics, durability, and compliance with sustainable building standards. ## Notable figures - At 22.1% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - Power density of 212.4 W/m² is 7.8 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 - At 35.0 kg (13.0 kg above \*\*TOPCon 400-450W\*\* median of 22.0 kg), requires checking roof load capacity - #6205 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### Why do SoliTek SOLRIF D Satin panels feature satin glass, and which buildings benefit most from it? The anti-glare satin glass surface reduces luminance to approximately 4,000 cd/m², eliminating the intense reflections produced by standard panels with clear glass. The solution was engineered for glare-sensitive locations such as airports, schools, expressways, and military facilities, where reflected sunlight poses safety risks or violates local regulations. Wherever bright solar reflections are a hazard or compliance issue, the SOLRIF D Satin directly addresses that problem. ### How does the Solrif D mounting system work, and does it truly replace conventional roofing? Yes. The patented Solrif D in-roof system by Ernst Schweizer AG integrates the panel directly into the roof structure, serving simultaneously as weatherproofing and a power generator. Panels slide into aluminum profiles similarly to roof tiles, with no need for separate battens, gutters, or sealing elements. Installation is fast, up to 20 modules per hour, and each module can be replaced independently. The system supports both full roof integration and partial replacement of existing coverings. ### What warranty comes with SoliTek SOLRIF D Satin panels? SoliTek provides a 30-year product warranty covering manufacturing defects and a 30-year power output warranty, among the longest standards available in the PV industry. The dual-glass glass-to-glass construction using 3.2+3.2 mm TVG combined with N-type TOPCon bifacial technology results in slower degradation rates than PERC cells, making the warranted output figures realistically achievable over the entire warranty period. ### How does the TOPCon bifacial technology in the SOLRIF D Satin differ from standard PERC cells? N-type TOPCon cells deliver higher conversion efficiency and a lower temperature coefficient than PERC, meaning less power loss on hot days. The bifacial design allows the panel to harvest irradiance from both glass surfaces, potentially boosting energy yield by several percentage points compared to monofacial modules. N-type cells also exhibit lower annual degradation rates, which is especially relevant for the 30-year operational horizon this series is built around. ### What weather resistance do the SOLRIF D Satin panels offer, and are they suitable for harsh climates? The SOLRIF D Satin series has passed rigorous durability testing. The panels hold hail resistance class 5, corresponding to 50 mm ice balls, the highest class in standard certification tests. Maximum certified snow load is 10,500 Pa. Modules are also rated for resistance to ammonia, salt mist, and corrosion, making them suitable for industrial and coastal environments as well as regions with heavy snowfall. ### What does the Cradle to Cradle Gold certification mean for SOLRIF D Satin panels, and why does it matter for public-sector projects? The Cradle to Cradle Gold certification confirms that 98% of materials used in the panel are recyclable and that SoliTek's entire manufacturing process runs on renewable energy. The SOLRIF D Satin is the only BIPV panel in the world holding this certification in its class. For public tenders, commercial real estate, and projects subject to ESG, BREEAM, or LEED requirements, this certification is a direct procurement argument and simplifies compliance with sustainable construction criteria. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Solrif-D-Satin-B96-445W-EN-datasheet-548d161d63c0.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, 16 kg 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 SOLRIF D Agro 300](https://comparepv.com/panel/ginlong-solis-solrif-d-agro-300) | 300 W | -145 W, -7.2 pp | | [Solitek SOLRIF D Terracota Bronze 370](https://comparepv.com/panel/ginlong-solis-solrif-d-terracota-bronze-370) | 370 W | -75 W, -3.7 pp | | [Solitek SOLRIF D Black 455](https://comparepv.com/panel/ginlong-solis-solrif-d-black-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-solrif-d-satin-445 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
