Thanks to the **patented aluminum frame with interlocking system**, the modules create a sealed, primary roofing layer - certified by DIBt - that is resistant to extreme weather conditions and snow loads. The all-glass construction allows for natural light transmission, making this series ideal for **balcony roofs, carports, greenhouses, and patios**, where both aesthetics and functionality are important. The use of N-type TOPCon bifacial technology allows for capturing radiation from both sides of the module, increasing energy yield even in limited roof space. The manufacturer guarantees durability with a **30-year product and performance warranty**, and the Cradle to Cradle Gold certification confirms European standards for production using renewable energy. The series features **Fire Class A** fire resistance, enhancing the safety of installations in residential and commercial buildings. ## Notable figures - Module efficiency of 14.7% is 1.3pp below average for \*\*TOPCon 0-400W\*\* panels (median: 16.0%) - At 141.5 W/m², this panel generates 18.3 W/m² less per unit area than \*\*TOPCon 0-400W\*\* median (159.8 W/m²) - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 0-400W\*\* panels - At 33.5 kg, this panel is 10.0 kg heavier than the \*\*TOPCon 0-400W\*\* median (23.5 kg) - more demanding for installation crews - #13986 for efficiency, #6152 for temperature performance out of 14129 panels ## Questions ### What is the peak power output of the Solitek SOLID Solrif Transparent and what makes its glass-glass construction special? The SOLID Solrif Transparent delivers a peak power of 435 Wp with cell efficiency of approximately 22%. The glass-glass construction (3.2+3.2 mm panes) provides exceptional durability and moisture resistance, while the transparent laminate transmits up to 40% more light than standard crystalline modules - a key advantage wherever natural light below the array matters. ### Can the Solitek SOLID Solrif Transparent panels fully replace a conventional roof covering? Yes - the SOLID Solrif Transparent is a BIPV module featuring a patented aluminum frame with an interlocking lap-joint system that forms a watertight primary roof layer, eliminating the need for a separate racking structure or underlayment. DIBt certification confirms compliance with European standards for extreme weather and snow-load resistance. ### What advantage does the bifacial N-type TOPCon cell technology offer in the SOLID Solrif Transparent series? N-type TOPCon cells achieve higher conversion efficiency and lower long-term degradation than conventional PERC cells. The bifacial design captures reflected irradiance from substrates such as carport floors or greenhouse walls, boosting annual energy yield by several percent - especially valuable on limited roof surfaces or structures with a light-colored soffit. ### What warranty does Solitek provide on the SOLID Solrif Transparent, and how long does the module retain its rated power? Solitek offers a 30-year product warranty and a 30-year linear power output warranty, guaranteeing at least 87% of the rated output after three decades of operation. This ranks among the longest warranties in the BIPV market and reflects the European manufacturing standards at Solitek's production facility in Lithuania. ### Which specific applications are the Solitek SOLID Solrif Transparent panels best suited for? The series excels wherever aesthetics and natural light transmission are priorities: terrace canopies, carports, greenhouses, pergolas, and garden pavilions. Its Fire Class A fire resistance rating permits installation on both residential and commercial buildings, while DIBt certification confirms its suitability as a stand-alone primary roof layer. ### Does the Solitek SOLID Solrif Transparent carry any environmental certifications, and where is it manufactured? Yes - the series holds the Cradle to Cradle Gold certificate, confirming production powered by 100% renewable energy and a 98% recyclability rate. Manufacturing takes place in Lithuania, EU, ensuring a short supply chain, reduced transport carbon footprint, and full compliance with stringent European production standards. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Rev20250923_Datasheet_SOLID_Solrif_D_Transparent_290W_compressed-4a6ca524aa32.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-300MH-72](https://comparepv.com/panel/ja-solar-ns-300mh-72) | 300 W | 21 kg lighter, +8.6 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-300MH-72](https://comparepv.com/panel/polycrown-solar-tech-ns-300mh-72) | 300 W | 21 kg lighter, +8.6 pp, -5 yr warranty | | [Heckert Solar ZEUS 1.2 FullBlack 280W](https://comparepv.com/panel/heckert-solar-zeus-1-2-fullblack-280w) | 280 W | Cooler, 19 kg lighter, +8.6 pp | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | 18 kg lighter, +8.5 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | 18 kg lighter, +8.5 pp, -5 yr warranty | | [Heckert Solar ZEUS 3.2 285WP FullBlack](https://comparepv.com/panel/heckert-solar-zeus-3-2-285wp-fullblack) | 285 W | Cooler, 18 kg lighter, +8.5 pp | | [Gamko New Energy GKA182M285W](https://comparepv.com/panel/gamko-new-energy-gka182m285w) | 285 W | 23 kg lighter, +8.3 pp | | [Gamko New Energy GKA182M240W](https://comparepv.com/panel/gamko-new-energy-gka182m240w) | 240 W | -50 W, 23 kg lighter, +8.3 pp | | [Gamko New Energy GKA182M260W](https://comparepv.com/panel/gamko-new-energy-gka182m260w) | 260 W | -30 W, 23 kg lighter, +8.3 pp | | [Solitek SOLID Solrif Terracotta Orange 285W](https://comparepv.com/panel/ginlong-solis-solid-solrif-terracotta-orange-285w) | 285 W | -0.2 pp | | [Solitek SOLID Solrif Terracotta Bronze 355](https://comparepv.com/panel/ginlong-solis-solid-solrif-terracotta-bronze-355) | 355 W | +65 W, lighter, +3.3 pp | | [Solitek SOLID Solrif 425](https://comparepv.com/panel/ginlong-solis-solid-solrif-425) | 425 W | +135 W, +6.8 pp | | [Solitek SOLID Solrif 435](https://comparepv.com/panel/ginlong-solis-solid-solrif-435) | 435 W | +145 W, lighter, +7.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +220 W, lighter, +10.3 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +205 W, lighter, +10.1 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +215 W, lighter, +10.0 pp | --- Source: https://comparepv.com/panel/ginlong-solis-solid-solrif-transparent-290 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
