The **glass-glass, frameless** design provides exceptional durability and resistance to extreme weather conditions: strong freezing temperatures, high temperatures, strong winds, and environments with high air salinity. The modules are 100% fire-resistant (Class A) and fully recyclable. The Blackstar series is suitable for a wide range of applications, including pitched and flat roofs, building facades, carports, and ground-mounted installations. The **Cradle to Cradle Silver** certification confirms compliance with circular economy principles, setting this series apart from most Asian competitors. The manufacturer offers a **30-year product warranty** and guarantees 90% power retention after three decades of operation - thanks to an exceptionally low annual degradation rate of 0.31%. The European origin of the panels ensures high quality consistency and a reliable supply chain. This is a solution for investors who prioritize long-term efficiency and a secure return on investment. ## Notable figures - Efficiency of 22.8% matches the \*\*TOPCon 450-500W\*\* median - At 227.7 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 25.5 kg (1.5 kg above \*\*TOPCon 450-500W\*\* median of 24.0 kg), requires checking roof load capacity - Ranked #3073 out of 14005 panels for efficiency in the database ## Questions ### Do the SoliTek Blackstar panels really generate power from both sides, and what does that mean in practice? Yes, the bifacial N-type TOPCon technology allows the Blackstar modules to absorb sunlight from both the front and rear surfaces. With a reflective substrate — white membrane, gravel, or concrete — energy yield can increase by up to 15–20% compared to a conventional monofacial module. The effect is most pronounced in ground-mounted systems and on flat roofs with a light-colored surface. ### What is the warranty on SoliTek Blackstar panels, and what does the 90% power guarantee after 30 years mean? SoliTek provides a 30-year product warranty and a 30-year power output warranty. The manufacturer guarantees that after three decades of operation the module will retain at least 90% of its rated power output, thanks to an exceptionally low annual degradation rate of 0.31%. For comparison, most conventional PERC panels degrade at 0.5–0.7% per year. ### Are Blackstar panels suitable for pitched roofs, and can they be used on building facades? Yes, the Blackstar series is designed for pitched roofs, flat roofs, and BIPV facade applications. The frameless glass-glass construction gives the modules a clean architectural appearance, making them ideal for modern building integration. The panels withstand mechanical loads up to 8,100 Pa, ensuring resistance to high winds and heavy snow. They also perform well in carports and ground-mounted installations. ### How does the frameless glass-glass construction of the Blackstar panels differ from standard aluminum-framed modules? Standard modules use a polymer backsheet and an aluminum frame. The Blackstar uses dual tempered glass with no frame, which is more resistant to moisture, frost, UV degradation, and corrosion in salt-laden environments such as coastal locations. This construction also delivers fire class A rating, critical for installations on commercial building facades and rooftops. The modules are also 100% recyclable. ### What is N-type TOPCon technology, and how does it differ from popular PERC panels? TOPCon (Tunnel Oxide Passivated Contact) is a next-generation N-type cell technology. Compared to mainstream PERC, it delivers higher efficiency — above 22% — a lower light-induced degradation (LID) rate, and better performance at elevated cell temperatures. N-type cells are less susceptible to internal degradation, which directly translates into higher energy output throughout the 30-year lifespan of the 455 Wp Blackstar module. ### Why choose Lithuanian SoliTek Blackstar panels over cheaper Asian alternatives? European manufacturing (Lithuania) means higher quality control standards, a stable supply chain, and legal accountability under EU regulations. The Blackstar series holds Cradle to Cradle Silver certification, confirming compliance with circular economy principles — a distinction absent from the vast majority of Asian manufacturers. Over a 30-year warranty horizon, the financial stability and reputation of the manufacturer are critical for investment security. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/BLACKSTAR-B96-455W-EN-f50199547034.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +40 W, lighter, +2.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +50 W, cooler, +1.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +1.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +45 W, cooler, +1.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +45 W, lighter, +1.7 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +45 W, lighter, +1.7 pp | | [Solitek SOLID Agro Framed 300](https://comparepv.com/panel/ginlong-solis-solid-agro-framed-300) | 300 W | -155 W, heavier, -7.8 pp | | [Solitek SOLID Agro Frameless 300](https://comparepv.com/panel/ginlong-solis-solid-agro-frameless-300) | 300 W | -155 W, heavier, -7.9 pp | | [Solitek SOLID Satin 445W](https://comparepv.com/panel/ginlong-solis-solid-satin-445w) | 445 W | -10 W, heavier, -0.7 pp | | [Solitek Blackstar Satin 445](https://comparepv.com/panel/ginlong-solis-blackstar-satin-445) | 445 W | -10 W, -0.5 pp | | [Solitek SOLID Black Frameless 455](https://comparepv.com/panel/ginlong-solis-solid-black-frameless-455) | 455 W | Heavier | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/ginlong-solis-blackstar-455 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
