Thanks to the **glass-glass construction with black backing glass**, the modules have a uniform black appearance from both sides - ideal for installations where the appearance is important. The **bifacial** technology allows for energy generation from both the front and back of the panel, resulting in significantly higher energy yields compared to standard monofacial modules - especially on bright surfaces or rooftops. The series is distinguished by its exceptional durability - the modules withstand extreme loads from snow, wind, and hail, and the A-class fire rating provides additional safety. The manufacturer guarantees a **30-year product warranty** while maintaining high performance throughout this period. The prestigious **Cradle to Cradle GOLD** certificate confirms European, environmentally responsible production standards. The panels are available in both frameless and framed versions, making them an ideal choice for both roof installations and modern BIPV projects - wherever high energy efficiency goes hand in hand with demanding aesthetics. ## Notable figures - At 22.1% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - Power density of 220.7 W/m² matches the \*\*TOPCon 400-450W\*\* median - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - Weight of 32.0 kg is 10.0 kg above \*\*TOPCon 400-450W\*\* median (22.0 kg) - verify structural support - In the top 44% for efficiency among all TOPCon panels ## Questions ### How much more energy do Solitek SOLID Bifacial Full Black panels produce compared to standard monofacial modules? Thanks to bifacial technology, Solitek SOLID Bifacial Full Black panels harvest energy from both the front and rear sides of the cell. On reflective surfaces such as light-colored roofing, gravel, or snow, the bifacial gain can reach up to 35% over standard monofacial modules. In typical rooftop installations, the gain usually ranges from 5% to 15%, depending on substrate albedo and tilt angle. ### What warranty is offered on Solitek SOLID Bifacial Full Black panels and what does it cover? Solitek provides an exceptionally long 30-year product warranty covering material and workmanship defects. A separate 30-year power output warranty guarantees the panel will retain at least 90% of its nominal 435 Wp after three decades. This is among the longest warranties available in the PV market and a key differentiator of the SOLID series. ### Are Solitek SOLID Full Black panels suitable for pitched roof installations and BIPV projects? Yes, the Solitek SOLID Bifacial Full Black series is available in both frameless and framed (35 mm) versions, making it an excellent fit for standard pitched roof systems as well as advanced BIPV (Building-Integrated Photovoltaics) applications. The uniformly black appearance on both sides - achieved through the black rear glass in a glass-glass construction - ensures a clean aesthetic even in highly visible locations. ### How do Solitek SOLID Bifacial Full Black panels hold up against heavy snow, strong wind, and hail? SOLID Bifacial Full Black modules carry a Class A fire rating and are engineered to withstand extreme mechanical loads - wind and snow pressure up to 10,500 Pa - as well as hail impact. The rigid glass-glass construction provides exceptional structural integrity. A competitive temperature coefficient of Pmax at -0.3%/°C means minimal power loss during cold winters compared to older PERC technology. ### How does the TOPCon cell technology in Solitek SOLID Bifacial Full Black panels differ from older PERC cells? N-type TOPCon (Tunnel Oxide Passivated Contact) cells deliver approximately 22% module efficiency, noticeably higher than typical PERC cells. TOPCon also exhibits lower recombination losses, stronger resistance to light-induced degradation (LID), and better performance at elevated temperatures. These characteristics are precisely what enables Solitek to back the SOLID series with a 30-year power output warranty. ### What does the Cradle to Cradle GOLD certification on Solitek SOLID Full Black panels mean and why does it matter when purchasing? The Cradle to Cradle GOLD certification confirms that Solitek SOLID panels are manufactured to the highest European environmental standards. The modules are lead- and cadmium-free and 100% recyclable thanks to the glass-glass construction. Solitek's Lithuanian factory is one of the few European PV manufacturers holding this prestigious certification, which matters increasingly for ESG compliance and subsidy programs that favor European-made products. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/faf67ec37e4104f44aeefd67.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +50 W, lighter, +2.2 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +50 W, lighter, +2.2 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, lighter, +2.2 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, lighter, +2.2 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +50 W, lighter, +2.2 pp | | [Solitek SOLID Agro 290](https://comparepv.com/panel/ginlong-solis-solid-agro-290) | 290 W | -145 W, -7.4 pp | | [Solitek SOLID Bifacial Anti-Glare 425](https://comparepv.com/panel/ginlong-solis-solid-bifacial-anti-glare-425) | 425 W | -10 W, heavier, -0.3 pp | | [Solitek SOLID Bifacial 425](https://comparepv.com/panel/ginlong-solis-solid-bifacial-425) | 425 W | -10 W, heavier, -0.3 pp | | [Solitek SOLID 435 Bifacial Transparent](https://comparepv.com/panel/ginlong-solis-solid-435-bifacial-transparent) | 435 W | Heavier | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +75 W, lighter, +2.9 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +60 W, lighter, +2.7 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +70 W, lighter, +2.6 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +70 W, lighter, +2.6 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +55 W, lighter, +2.4 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +65 W, lighter, +2.4 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +65 W, lighter, +2.4 pp | --- Source: https://comparepv.com/panel/solitek-solid-bifacial-full-black-435 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
