The modules utilize **N-type TOPCon Half-Cut** cells in M10 format, which offer higher energy efficiency and improved resistance to degradation compared to PERC cells. The **bifacial** design (glass-on-glass) allows for energy generation from both the front and back of the module, which translates to higher daily energy yield. The SOLID Blackstar series is ideally suited for residential and commercial rooftops, and its **aluminum frame and all-black design** make it suitable for demanding architectural projects. The panels have a **Cradle to Cradle** certification, confirming the manufacturer's environmental responsibility and full recyclability. Fire resistance class A, resistance to harsh weather conditions (wind, frost, salt), and a long product warranty make this series an attractive option for investors who value reliability and long-term cost-effectiveness. ## Notable figures - Efficiency of 22.3% matches the \*\*TOPCon 400-450W\*\* median - At 222.8 W/m² power density, roof space requirements are typical for \*\*TOPCon 400-450W\*\* panels - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 400-450W\*\* median - Weight of 25.0 kg is 3.0 kg above \*\*TOPCon 400-450W\*\* median (22.0 kg) - verify structural support - Ranked #5544 out of 14129 panels for efficiency in the database ## Questions ### What warranty comes with the SoliTek SOLID Blackstar panels? The SOLID Blackstar series includes a 30-year product warranty and a 30-year power output warranty. SoliTek guarantees no more than 1% degradation in the first year and only 0.31% per year thereafter, ensuring at least 90% of rated power after 30 years of operation. This is among the strongest warranty terms available for European-manufactured PV modules. ### How does the TOPCon technology in the SOLID Blackstar compare to older PERC cells? The N-type TOPCon half-cut cells used in the SOLID Blackstar deliver module efficiency up to 22.04%, compared to 20-21% typical for PERC. More importantly, annual degradation is just 0.31% versus approximately 0.45% for PERC, and TOPCon cells are significantly less susceptible to LID (Light Induced Degradation). This results in meaningfully higher energy yield over the full 30-year system lifetime. ### Does the bifacial glass-glass construction of the SOLID Blackstar actually increase energy production? Yes. The bifacial design captures albedo light reflected from the surface beneath the module, boosting energy yield by up to 10-15% under favorable conditions such as a light-colored roof, gravel, or snow. The glass-glass encapsulation also extends module lifespan by eliminating backsheet degradation and improving resistance to moisture ingress and mechanical loads up to 8,100 Pa. ### Are the SoliTek SOLID Blackstar 435W panels suitable for a residential pitched roof? Yes, the SOLID Blackstar 435W is well-suited for residential rooftop installations. The all-black aluminum frame meets the aesthetic requirements of modern architecture, while the 8,100 Pa load rating ensures safety under heavy wind and snow conditions. The modules are compatible with standard racking and mounting systems widely available on the market. ### Where are SoliTek SOLID Blackstar panels manufactured, and does it matter? SoliTek SOLID Blackstar panels are manufactured in Lithuania, making them one of the very few PV modules produced entirely in Europe. European production means full quality oversight, a lower transportation carbon footprint, and no exposure to anti-dumping tariff risk. The series holds the Cradle to Cradle certification, confirming the manufacturer's environmental commitment and full end-of-life recyclability. ### Do SOLID Blackstar panels perform well in winter and low-irradiance conditions? Yes. N-type TOPCon technology has a low temperature power coefficient, so the modules lose less output on hot days compared to PERC cells. In winter, the bifacial design allows additional energy harvest from light reflected off snow. The panels are certified for salt mist, freeze-thaw cycling, and extreme wind resistance, making them a reliable choice for the demanding climates of Poland and Central Europe. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/BLACKSTAR_435Wp_compressed-54f75e238ca5.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, +2.0 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, cooler, +2.0 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, lighter, +2.0 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +50 W, cooler, +2.0 pp | | [Solitek SOLID Agro 290](https://comparepv.com/panel/ginlong-solis-solid-agro-290) | 290 W | -145 W, heavier, -7.6 pp | | [Solitek SOLID Bifacial Anti-Glare 425](https://comparepv.com/panel/ginlong-solis-solid-bifacial-anti-glare-425) | 425 W | -10 W, heavier, -0.5 pp | | [Solitek SOLID Bifacial 425](https://comparepv.com/panel/ginlong-solis-solid-bifacial-425) | 425 W | -10 W, heavier, -0.5 pp | | [Solitek SOLID Bifacial Full black 435](https://comparepv.com/panel/solitek-solid-bifacial-full-black-435) | 435 W | Heavier | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +75 W, cooler, +2.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +60 W, lighter, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +70 W, cooler, +2.4 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +70 W, cooler, +2.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +55 W, lighter, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +65 W, cooler, +2.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +65 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/ginlong-solis-solid-blackstar-435 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
