The modules use monocrystalline half-cut cells arranged in six independent strings, which reduces power losses under partial shading and improves resistance to microcracks. The **black anodised frame** gives the panels a clean, uniform appearance, making them well suited to industrial rooftops as well as larger business installations where building aesthetics are a priority. The GEMINI series stands out from competing products with its **extended product warranty** and a linear performance guarantee spanning a quarter of a century, translating into a predictable return on investment and a lower levelized cost of energy (LCOE) over the system's lifetime. The construction withstands high mechanical loads, snow, and wind, while highly sealed connectors ensure safe operation in demanding weather conditions. This is a solution for investors and PV system designers who expect stable, proven technology from a European manufacturer along with clear warranty terms, not just a declared nominal panel output. ## Notable figures - At 21.0% efficiency, this panel is 0.8pp below the \*\*database\*\* median of 21.8% - 210.0 W/m² power density is 8.1 W/m² below \*\*database\*\* median (218.1 W/m²) - requires larger installation area - At -0.34%/°C, loses 0.04pp more power per degree than \*\*database\*\* median (-0.30%/°C) - 21.6 kg weight - 4.9 kg lighter than \*\*database\*\* median (26.5 kg), reducing installation effort - In the top 70% for efficiency among all N-type panels ## Questions ### Is the WINAICO WST-MGX-E3 GEMINI series still available for purchase? The WST-MGX-E3 GEMINI series has been discontinued by WINAICO and replaced by newer models in the current lineup. Panels may still be available from distributors as remaining stock, so it's worth confirming availability and production date with your supplier before ordering a larger batch for a commercial installation. ### What is the maximum power output of the WST-MGX-E3 GEMINI panel? The GEMINI series modules reach a maximum power output of up to 415 Wp. This is achieved using monocrystalline half-cut cells arranged in six independent strings, delivering high power density while maintaining good resistance to partial shading, common on industrial rooftops with ventilation equipment. ### What warranty applies to WINAICO GEMINI panels? WINAICO provides a 15-year product warranty and a 25-year linear power output warranty on the GEMINI series. This means the manufacturer covers not only manufacturing defects but also guarantees a defined power output level over a quarter century, helping investors precisely calculate ROI for commercial PV installations. ### Are the WST-MGX-E3 GEMINI panels bifacial? No, the WST-MGX-E3 GEMINI series consists of monofacial panels and does not use bifacial technology. This means they generate electricity only from sunlight hitting the front surface of the module, a standard approach for typical rooftop installations where modules are mounted close to the roof surface. ### What distinguishes the frame design of WINAICO GEMINI panels? GEMINI panels feature a black anodized frame that gives them a uniform, aesthetic appearance, beneficial where building facade design matters, such as office or warehouse installations with a visible roof section. The frame withstands high mechanical loads, including heavy snow and strong wind, as confirmed by manufacturer certifications. ### Is WINAICO a Tier 1 manufacturer, and where is it based? Yes, WINAICO is classified as a Tier 1 manufacturer, confirming financial stability and years of experience in producing photovoltaic modules. The company is headquartered in Taiwan, where it manufactures to international quality standards, an important factor when selecting a supplier for large commercial installations with long-term warranties. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/WINAICO_Datasheet_WST-415MGX-E3_EU_0224-7a3124c2340b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | +50 W, cooler, +2.6 pp | | [Just Solar JST-EDMH-(445-465)W-TD (460W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-460w-class) | 460 W | +50 W, +2.6 pp, +5 yr warranty | | [Luxor Solar LX-460M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-460m-182r-96-gg) | 460 W | +50 W, cooler, +2.6 pp | | [Philadelphia Solar PS-MNB108(HCBF)-460W](https://comparepv.com/panel/philadelphia-solar-ps-mnb108-hcbf-460w) | 460 W | +50 W, cooler, +2.5 pp | | [JA Solar JAT54S40-460/LR](https://comparepv.com/panel/ja-solar-jat54s40-460-lr) | 460 W | +50 W, cooler, +2.5 pp | | [Luxor Solar LX-460M/182R188-108+ GG](https://comparepv.com/panel/luxor-solar-lx-460m-182r188-108-gg) | 460 W | +50 W, cooler, +2.4 pp | | [AIKO AIKO-455-MAH54Db](https://comparepv.com/panel/aiko-aiko-455-mah54db) | 455 W | Cooler, +2.3 pp, +5 yr warranty | | [Longi Solar LR5-54HTH-455M](https://comparepv.com/panel/longi-lr5-54hth-455m) | 455 W | +45 W, cooler, +2.3 pp | | [WINAICO WST-400MGX-P3 Full Black](https://comparepv.com/panel/winaico-wst-400mgx-p3-full-black) | 400 W | -10 W, -0.6 pp | | [WINAICO WST-405MGX-E5](https://comparepv.com/panel/winaico-wst-405mgx-e5) | 405 W | Cooler | | [WINAICO WST-410MGX-P3](https://comparepv.com/panel/winaico-wst-410mgx-p3) | 410 W | Very close match | | [WINAICO WST-415MGX-E3](https://comparepv.com/panel/winaico-wst-415mgx-e3) | 415 W | +0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +100 W, cooler, +4.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +85 W, cooler, +3.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +95 W, cooler, +3.7 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +95 W, cooler, +3.7 pp | --- Source: https://comparepv.com/panel/winaico-wst-410mgx-e3 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.
