These European-made modules feature a **glass-to-glass bifacial technology**, which allows for energy generation from both sides of the panel, increasing yields even in diffuse and reflected light conditions. Thanks to the double-glazed construction, the panels offer exceptional mechanical strength and certified resistance to salt fog and ammonia - making them ideal for demanding environments such as agricultural sites, coastal installations, and parking canopies. The series meets the highest fire safety standards (Class A) and has a **Cradle to Cradle** certification, confirming near 100% recyclability. The manufacturer offers a 30-year product and performance warranty, and the modules are designed for a 50-year lifespan. **SOLID Framed Transparent** is particularly well-suited for **BIPV (Building Integrated Photovoltaics)** applications - where solar panels are integrated into buildings - as well as greenhouses, terrace covers, and carports, where aesthetics, transparency, and durability are paramount. ## Notable figures - At 22.3% efficiency, this panel is on par with typical \*\*TOPCon 500-550W\*\* modules - Power density of 223.1 W/m² is 4.3 W/m² below \*\*TOPCon 500-550W\*\* median (227.4 W/m²) - needs more roof space - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 500-550W\*\* panels - At 29.0 kg, this panel is 2.0 kg heavier than the \*\*TOPCon 500-550W\*\* median (27.0 kg) - more demanding for installation crews - #5082 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### What is the maximum power output of the Solitek SOLID Framed Transparent series, and what cell technology does it use? The top variant in the series reaches 505 Wp and uses n-type TOPCon cells, which deliver higher efficiency and slower power degradation compared to older PERC technology. The bifacial glass-glass construction harvests energy from both sides of the module, boosting annual energy yield — especially over reflective surfaces or under diffuse light conditions. ### Are SOLID Framed Transparent panels suitable for carports, greenhouses, or terrace canopies? Yes — that is one of the primary use cases for this series. The transparent glass-glass structure with an aluminum frame transmits natural daylight, making these modules ideal for BIPV applications: carports, terrace canopies, horticultural and industrial greenhouses, and building facades. The combination of aesthetics, energy generation, and interior daylighting is the main advantage over conventional opaque panels. ### Can Solitek SOLID Framed Transparent panels handle harsh environments such as coastal locations or livestock buildings? Yes. The series carries certified resistance to salt mist (coastal environments) and ammonia (agricultural buildings such as stables and pig farms). The dual-glass construction also provides superior mechanical strength. Modules meet fire safety Class A standards and are manufactured in Europe for a projected 50-year service life. ### Does the bifacial design of SOLID Framed Transparent panels actually produce more energy? In typical installations with a bright or reflective surface below (light-colored carport floor, snow, gravel, or a light-colored facade), bifaciality can increase annual energy yield by 5–15% compared to a similarly rated monofacial panel. The n-type TOPCon technology also reduces losses at high temperatures and under diffuse irradiance, which is particularly relevant in Central European climates. ### What warranty does the Solitek SOLID Framed Transparent series carry, and what does it cover? Solitek provides a 30-year product warranty (covering material and manufacturing defects) and a 30-year power output warranty. Modules are designed for a 50-year operational lifespan. For context, the industry standard is typically 10–12 years of product warranty and 25 years of power warranty, making Solitek's offering noticeably stronger than the market norm. ### Are SOLID Framed Transparent panels recyclable, and does Solitek hold a certification for this? Yes. The series holds the Cradle to Cradle certificate, confirming recyclability at nearly 100%. The glass-glass build without a polymer backsheet simplifies material recovery at end of life. This is a meaningful differentiator for investors or companies subject to ESG reporting requirements or those looking to minimize the environmental footprint of their PV installation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Rev20251006_Solid_Framed_505W_compressed-cf2d1a7de3a0.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +2.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +50 W, lighter, +2.3 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +55 W, lighter, +2.5 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +45 W, lighter, +2.1 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +2.1 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +2.1 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +40 W, cooler, +2.0 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | +40 W, lighter, +1.9 pp | --- Source: https://comparepv.com/panel/ginlong-solis-solid-framed-transparent-505 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
