The modules replace traditional tiles, mounted directly on the roof - without any additional support structure - creating a weatherproof and durable roofing solution. The distinctive Terracotta Orange (RAL 8023) color makes the installation virtually indistinguishable from traditional ceramic tiles, making it the ideal choice for buildings in conservation areas and historic districts, where traditional black panels would be unacceptable. The **N-type TOPCon bifacial** technology, combined with the glass-glass construction, provides exceptional durability - resistance to hail Class 5, the highest fire resistance rating A, and extreme resistance to snow and wind loads. The **Cradle to Cradle Gold** certification and production using 100% renewable energy make this series stand out in terms of environmental friendliness and sustainability. The module has prestigious DIBt construction approval, simplifying the formalities of roof modernization. **30-year product and performance warranty** with guaranteed 90% power after 30 years is among the longest standards in the industry. The series is dedicated to demanding private investments, historic buildings, and projects where the aesthetics of the roof are of paramount importance. ## Notable figures - Module efficiency of 14.4% is 1.5pp below average for \*\*TOPCon 0-400W\*\* panels (median: 16.0%) - 139.0 W/m² power density is 20.8 W/m² below \*\*TOPCon 0-400W\*\* median (159.8 W/m²) - requires larger installation area - 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 - Ranked #14014 out of 14129 panels for efficiency in the database ## Questions ### Do SOLID Solrif Terracotta Orange panels actually look like traditional roof tiles, and can they be used in heritage conservation zones? Yes. The SOLID Solrif modules in Terracotta Orange (RAL 8023) are engineered to visually replicate traditional ceramic roof tiles. The color is virtually indistinguishable from original ceramics, which is why this series has been approved for use in historic districts and heritage-protected areas where standard black PV panels are not permitted. This is further backed by the prestigious DIBt building approval. ### How does the SOLID Solrif installation work - is any additional roof structure needed? No additional mounting structure is required. The SOLID Solrif is a BIPV (Building-Integrated Photovoltaics) solution - modules are installed directly onto roof battens, replacing conventional roof tiles. There is no need for sub-framing or underlayment supports. The panels simultaneously form a weatherproof roof covering and an energy-generating surface, simplifying the project and reducing material costs. ### What warranty comes with the SOLID Solrif panels, and how much power output is guaranteed after 30 years? Solitek offers a 30-year product warranty covering manufacturing defects and a 30-year linear power output warranty guaranteeing at least 90% of rated power after the full 30-year period. This ranks among the longest warranty standards in the PV industry and reflects the manufacturer's confidence in the durability of the glass-glass construction with N-type TOPCon technology. ### What is N-type TOPCon technology used in the SOLID Solrif, and how does it compare to older PERC technology? TOPCon (Tunnel Oxide Passivated Contact) uses an N-type silicon base with a thin tunnel oxide passivation layer that minimizes carrier recombination losses. Compared to PERC, it delivers higher efficiency, a better temperature coefficient (approx. -0.30%/°C vs. -0.35%/°C), and slower long-term degradation. In the SOLID Solrif, this translates to greater energy yield over the entire 30-year warranty period. ### Are the SOLID Solrif panels resistant to heavy hail and significant snow loads? Yes. The glass-glass construction (two layers of 3.2 mm heat-strengthened glass) provides Class 5 hail resistance - the highest rating under the IEC standard. The SOLID Solrif series withstands extreme snow and wind loads of up to 10.5 kPa and achieves the highest fire resistance class A. This is especially critical when the modules function as the primary roof covering, subject to the same requirements as traditional tiles. ### What does the Cradle to Cradle Gold certification on the SOLID Solrif mean for an investor? The Cradle to Cradle Gold certification confirms that the modules are designed for a circular economy - materials are recyclable and production at SoliTek's Lithuanian factory runs on 100% renewable energy. For investors, this means a fully documented low-carbon product, which is relevant for ESG reporting, green building subsidies, or procurement requirements mandating sustainable supply chains. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Rev20251125_Solid-Solrif_Terracotta-Orange_D-b3824be76f8a.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, +8.9 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, +8.9 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, +8.9 pp | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | 18 kg lighter, +8.7 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, +8.7 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, +8.7 pp | | [Gamko New Energy GKA182M285W](https://comparepv.com/panel/gamko-new-energy-gka182m285w) | 285 W | 23 kg lighter, +8.6 pp | | [Gamko New Energy GKA182M240W](https://comparepv.com/panel/gamko-new-energy-gka182m240w) | 240 W | -45 W, 23 kg lighter, +8.6 pp | | [Gamko New Energy GKA182M260W](https://comparepv.com/panel/gamko-new-energy-gka182m260w) | 260 W | -25 W, 23 kg lighter, +8.6 pp | | [Solitek SOLID Solrif Transparent 290](https://comparepv.com/panel/ginlong-solis-solid-solrif-transparent-290) | 290 W | +0.2 pp | | [Solitek SOLID Solrif Terracotta Bronze 355](https://comparepv.com/panel/ginlong-solis-solid-solrif-terracotta-bronze-355) | 355 W | +70 W, lighter, +3.6 pp | | [Solitek SOLID Solrif 425](https://comparepv.com/panel/ginlong-solis-solid-solrif-425) | 425 W | +140 W, +7.1 pp | | [Solitek SOLID Solrif 435](https://comparepv.com/panel/ginlong-solis-solid-solrif-435) | 435 W | +150 W, lighter, +7.6 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +225 W, lighter, +10.6 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +210 W, lighter, +10.4 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +220 W, lighter, +10.2 pp | --- Source: https://comparepv.com/panel/ginlong-solis-solid-solrif-terracotta-orange-285w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
