Its core is **N-type TOPCon double-sided cells**, which generate energy from both the front and back of the module, significantly increasing energy yield without the need for a larger land footprint. The 120-cell architecture makes Magnus offer an exceptionally favorable power-to-space ratio, reducing installation and associated infrastructure costs. The durable **2mm+2mm glass-glass construction** provides exceptional mechanical resistance - the panel withstands hail up to 40 mm in diameter and extreme weather conditions typical of the European climate. The modules are manufactured in Europe, guaranteeing shorter supply chains, a lower carbon footprint, and predictable quality. The series has a prestigious **Cradle to Cradle Gold** certification, confirming environmental responsibility at every stage of the product lifecycle - from sustainable production to complete recycling. The manufacturer offers a **30-year product warranty**, making Magnus an exceptionally attractive choice for developers of photovoltaic farms and industrial investors seeking long-term investment security and minimizing the overall system cost. ## Notable figures - At 22.9% efficiency, this panel is on par with typical \*\*TOPCon 500-550W\*\* modules - At 229.3 W/m² power density, roof space requirements are typical for \*\*TOPCon 500-550W\*\* panels - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 500-550W\*\* panels - At 28.5 kg, this panel is 1.5 kg heavier than the \*\*TOPCon 500-550W\*\* median (27.0 kg) - more demanding for installation crews - #2342 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### Are SoliTek Magnus panels suitable for large-scale solar farms and commercial rooftop installations? Yes, the Magnus series was specifically engineered for utility-scale and large commercial applications — solar farms and expansive rooftop systems on industrial buildings. With 120 N-type TOPCon bifacial cells and up to 510 Wp peak power, fewer modules are needed per megawatt, reducing balance-of-system (BoS) costs. European manufacturing ensures reliable supply chains and consistent quality, both critical for large-scale procurement. ### What warranty does the SoliTek Magnus solar panel come with? SoliTek backs the Magnus with a 30-year product warranty covering material and workmanship defects, plus a 30-year linear power output guarantee. This extended coverage is a key advantage for solar farm developers and industrial investors who require long-term performance certainty and want to minimize unexpected O&M costs over the full system lifecycle. ### What is N-type TOPCon technology and how does it compare to older PERC panels in the Magnus series? TOPCon (Tunnel Oxide Passivated Contact) is an advanced N-type silicon cell technology that delivers higher module efficiency and lower long-term degradation rates compared to PERC. It also performs better at elevated operating temperatures and under diffuse irradiance on overcast days. Magnus reaches up to 22.93% module efficiency, translating into more kilowatt-hours per unit area across the full 30-year operational lifetime. ### What does bifacial mean for the Magnus panel, and how much additional energy can the rear side generate? Bifacial modules capture irradiance from both the front and the rear surface, utilizing light reflected from the ground, rooftop, or surrounding environment. In ground-mount solar farms with light-colored surfaces, bifacial gain typically adds 10–15% in additional energy yield. The 2mm+2mm glass-glass construction protects the rear cell surface for the full 30-year operational lifetime without degradation caused by moisture or UV exposure. ### Are SoliTek Magnus panels resistant to hail and harsh weather conditions? Yes. The 2mm+2mm glass-glass construction allows Magnus to withstand hailstones up to 40 mm in diameter and the extreme weather conditions typical of the European climate. The frameless glass-glass design also eliminates corrosion risk at aluminum-frame contact points — an important long-term reliability benefit for utility-scale and industrial installations exposed to decades of outdoor conditions. ### What is the Cradle to Cradle Gold certification and why does it matter when purchasing Magnus panels? Cradle to Cradle Gold is one of the world's most rigorous sustainability standards, evaluating products across material health, circularity, clean production, water stewardship, and social fairness. For the Magnus series it confirms environmentally responsible practices at every stage of the product lifecycle, from European manufacturing through to full end-of-life recycling. This is a significant advantage for investors pursuing ESG targets, green financing, or carbon footprint reporting obligations. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Datasheet-solitek-Magnus-510W_EN-a99eb63d6794.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +2.1 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +1.9 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +50 W, cooler, +1.9 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +1.8 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +45 W, cooler, +1.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +1.6 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +1.6 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +40 W, lighter, +1.5 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | Cooler, lighter, +1.5 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | Cooler, lighter, +1.5 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +35 W, cooler, +1.3 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | +35 W, cooler, +1.3 pp | --- Source: https://comparepv.com/panel/ginlong-solis-magnus-510 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.
