Thanks to the **unique Solrif mounting system**, the modules are mounted directly as part of the roof structure, eliminating the need for traditional supports and ensuring a watertight seal comparable to traditional tiles. The **uniform, full-black surface** without visible metal elements allows the installation to seamlessly blend into the roof, creating a cohesive and architecturally refined whole. The technology of **N-type TOPCon bifacial solar cells** ensures high performance even under low irradiance or cloudy conditions. The **glass-glass construction** guarantees exceptional mechanical resistance to snow, hail, and strong winds, and the 30-year product and power warranty confirms the longevity of the series. DIBt certification allows the panels to be used in construction even in demanding climatic conditions. This is a solution for discerning investors, architects, and developers seeking modules that combine **the highest level of aesthetics with excellent energy parameters** - ideal for modern single-family homes, residential developments, and BIPV projects, where the appearance of the roof is a priority. ## Notable figures - Efficiency of 22.0% matches the \*\*TOPCon 400-450W\*\* median - 212.2 W/m² power density is 8.0 W/m² below \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - requires larger installation area - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - At 27.0 kg, this panel is 5.0 kg heavier than the \*\*TOPCon 400-450W\*\* median (22.0 kg) - more demanding for installation crews - In the top 45% for efficiency among all TOPCon panels ## Questions ### How does the Solrif mounting system work, and do SOLID Solrif Full Black panels replace traditional roofing? Yes, SOLID Solrif Full Black panels are installed using the proprietary Solrif system developed in partnership with Swiss company Ernst Schweizer AG. The modules replace conventional tiles or sheet metal, forming a watertight roof covering without additional brackets. The system delivers weatherproofing comparable to traditional roofing, while the absence of visible metal elements creates a clean, fully black roof surface. ### What is the actual energy gain from bifacial cells in the SOLID Solrif Full Black series? The bifacial N-type TOPCon cells in this series can generate up to 35% additional energy from the rear side of the module by capturing light reflected from the roof surface or surroundings. The bifacial gain is most pronounced on installations with lighter substrates or higher-albedo rooftops. Front-side rated power reaches 435 Wp, with real-world output exceeding that figure thanks to the bifacial effect. ### What warranty comes with Solitek SOLID Solrif Full Black panels and what does it cover? The SOLID Solrif Full Black series carries a 30-year product warranty and a 30-year power output warranty. Manufacturer Solitek, headquartered in Lithuania, also guarantees module longevity for at least 50 years. The warranty covers manufacturing defects and guaranteed power output levels throughout the service life, which stands out against the industry-standard 10-12-year product warranty offered by many competitors. ### Do SOLID Solrif Full Black panels perform well in winter, overcast skies, and low-irradiance conditions? Yes. N-type TOPCon technology features a low power temperature coefficient of -0.30% per degree Celsius, meaning minimal losses on cold but sunny days. Bifacial cells also capture diffuse irradiance more effectively under cloud cover. The glass-glass construction (3.2+3.2 mm) withstands snow loads up to 10,500 Pa, making the panels well-suited for climates with heavy winter precipitation. ### What is the hail and wind resistance rating for the SOLID Solrif Full Black series? The SOLID Solrif Full Black series is certified to hail resistance Class 5, meaning it withstands hailstones up to 50 mm in diameter at impact speeds exceeding 35 m/s. Wind load resistance reaches 3,600 Pa and snow load resistance 10,500 Pa. The modules also hold Fire Class A certification and DIBt approval, qualifying them for use as a building component in demanding climatic conditions. ### Is the SOLID Solrif Full Black series suitable for BIPV projects and residential architecture? Yes, BIPV is one of the primary use cases for this series. DIBt (Deutsches Institut für Bautechnik) certification qualifies the panels as a structural building element. The uniform full-black surface with no visible screws or frames makes the modules ideal for modern single-family homes, residential developments, and BIPV projects where roof aesthetics are a priority. The 1767 × 1160 mm dimensions simplify alignment with standard roof geometries. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/rev20251006solid-solrif-n-b108435w-full-blackcompressed-0594fd119f3f.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, +2.3 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +50 W, lighter, +2.3 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +50 W, lighter, +2.3 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +50 W, lighter, +2.3 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +50 W, cooler, +2.3 pp | | [Solitek SOLID Solrif Terracotta Orange 285W](https://comparepv.com/panel/ginlong-solis-solid-solrif-terracotta-orange-285w) | 285 W | -150 W, heavier, -7.6 pp | | [Solitek SOLID Solrif Transparent 290](https://comparepv.com/panel/ginlong-solis-solid-solrif-transparent-290) | 290 W | -145 W, heavier, -7.3 pp | | [Solitek SOLID Solrif Terracotta Bronze 355](https://comparepv.com/panel/ginlong-solis-solid-solrif-terracotta-bronze-355) | 355 W | -80 W, -4.0 pp | | [Solitek SOLID Solrif 425](https://comparepv.com/panel/ginlong-solis-solid-solrif-425) | 425 W | -10 W, heavier, -0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +75 W, cooler, +3.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +60 W, lighter, +2.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +70 W, cooler, +2.7 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +70 W, cooler, +2.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +55 W, lighter, +2.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +65 W, cooler, +2.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +65 W, lighter, +2.5 pp | --- Source: https://comparepv.com/panel/ginlong-solis-solid-solrif-435 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
