Its **distinctive, matte bronze color** perfectly complements historic urban landscapes, meeting stringent conservation requirements in historic city centers dominated by red-tiled roofs. Special glass coatings reduce reflections, making the panel appear like a standard ceramic tile from the street, rather than a typical solar panel. The construction, featuring **double-tempered glass**, guarantees exceptional mechanical strength, certified to a Class 5 hail resistance. A wide range of mounting angles and high resistance to snow and wind loads make it a versatile solution for year-round use. **A 30-year product and performance warranty**, along with **Cradle to Cradle Gold certification**, confirms the highest standard of sustainable production, carried out in Europe using renewable energy. The series is primarily intended for investors renovating historic buildings, villas, and protected structures, where the use of standard solar panels is impossible or undesirable. ## Notable figures - Efficiency of 18.0% is 2.0pp above the \*\*TOPCon 0-400W\*\* median (16.0%) - Power density of 173.2 W/m² packs 13.4 W/m² more into the same footprint vs \*\*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 - Ranked #13330 out of 14129 panels for efficiency in the database ## Questions ### Can Solitek SOLID Solrif Terracotta Bronze panels be installed on a historic tenement building subject to heritage conservation requirements? Yes, the SOLID Solrif Terracotta Bronze series was designed specifically for buildings under heritage conservation oversight. The matte bronze color mimics traditional ceramic roof tiles, and special glass coatings reduce light reflections so the modules look like classic tiles from street level rather than conventional solar panels. The system is installed without additional support framing, preserving the original roof geometry, which significantly simplifies obtaining heritage authority approval in historic city centers dominated by red-tiled rooftops. ### How does the Solitek SOLID Solrif Terracotta Bronze differ from standard solar panels - does it truly replace roof tiles? The SOLID Solrif Terracotta Bronze is a BIPV system in which the modules simultaneously function as waterproof roof cladding and a photovoltaic generator. Unlike standard PV panels mounted on top of an existing roof, Solrif is the roof itself - installed directly on battens without a separate ceramic tile layer and without any additional steel racking. This eliminates the cost of traditional tile covering and shortens the overall project timeline. ### What is TOPCon technology in the Solitek SOLID Solrif Terracotta Bronze series, and what does bifacial design offer in a rooftop BIPV application? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that delivers higher efficiency and a lower temperature coefficient than older PERC cells, meaning less power loss on hot days. The bifacial rear gain is smaller in a BIPV application than in ground-mount systems because the back pane is enclosed, but the glass-glass construction inherent to bifacial cell design translates directly into exceptional mechanical durability and an extended module service life. ### How resistant are Solitek SOLID Solrif Terracotta Bronze modules to hail, snow, and wind loads? The SOLID Solrif Terracotta Bronze modules use double-tempered glass (3.2 mm per pane) and carry a Class 5 hail resistance certificate, meaning they withstand impact from 50 mm diameter hailstones. The glass-glass construction handles mechanical loads up to 10,500 Pa, comfortably exceeding the structural requirements for typical European rooftops exposed to heavy snow accumulation or strong wind gusts. ### What warranty does Solitek provide on the SOLID Solrif Terracotta Bronze series and what does it cover? Solitek offers a 30-year product warranty and a 30-year power output warranty on the SOLID Solrif Terracotta Bronze series. The product warranty covers material and manufacturing defects, while the power warranty guarantees a minimum percentage of nominal output throughout the full 30-year operational period. The Cradle to Cradle Gold certification confirms that production takes place in Lithuania using 100% renewable energy and in accordance with circular economy principles. ### What is the maximum power output of a single Solitek SOLID Solrif Terracotta Bronze module, and is it enough for a single-family home? The maximum rated power of a single SOLID Solrif Terracotta Bronze module is 355 Wp. Because each module is sized to match a standard ceramic roof tile, total system output depends on available roof area. For a typical single-family home with a sufficiently large roof section, the installed capacity can cover a substantial share of annual electricity consumption. A precise system design should be prepared by an installation company experienced in BIPV solutions. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Rev20251006_Solid-Solrif_Terracotta-Bronze_D-10-09_compressed-fb895db9ee5c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | 18 kg lighter, +5.1 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, +5.1 pp, -5 yr warranty | | [Gamko New Energy GKA210M320W](https://comparepv.com/panel/gamko-new-energy-gka210m320w) | 320 W | -35 W, 17 kg lighter, +5.0 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | -15 W, 17 kg lighter, +5.0 pp | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | 17 kg lighter, +5.0 pp | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | +25 W, 16 kg lighter, +5.0 pp | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | +45 W, 16 kg lighter, +5.0 pp | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | +45 W, 16 kg lighter, +5.0 pp | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | +25 W, 16 kg lighter, +5.0 pp | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Lighter, +4.6 pp, +10 yr warranty | | [Solitek SOLID Solrif Terracotta Orange 285W](https://comparepv.com/panel/ginlong-solis-solid-solrif-terracotta-orange-285w) | 285 W | -70 W, -3.6 pp | | [Solitek SOLID Solrif Transparent 290](https://comparepv.com/panel/ginlong-solis-solid-solrif-transparent-290) | 290 W | -65 W, -3.3 pp | | [Solitek SOLID Solrif 425](https://comparepv.com/panel/ginlong-solis-solid-solrif-425) | 425 W | +70 W, +3.5 pp | | [Solitek SOLID Solrif 435](https://comparepv.com/panel/ginlong-solis-solid-solrif-435) | 435 W | +80 W, lighter, +4.0 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +155 W, lighter, +7.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +140 W, lighter, +6.8 pp | --- Source: https://comparepv.com/panel/ginlong-solis-solid-solrif-terracotta-bronze-355w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
