For project financing by banks and insurers, this translates to lower counterparty risk compared to non-Tier-1 manufacturers. - **Efficiency Up to 20.74% – Top of Segment** - The peak efficiency of 20.74% matches that of direct peer comparables VSUN VSUN405-108BMH-DG and Solarspace Lumina I, and exceeds the Goldi Solar GS10-M108-BF (20.66%). The series is fully competitive with rivals in terms of power density per square meter. - **Half-Cut Cells + SMBB – Shade Tolerance and Crack Resistance** - The half-cut cell design splits cells into 108 halves, reducing losses under partial shading and lowering hot-spot risk. The multi-busbar SMBB architecture shortens the current path, reducing series resistance and mechanical stress during installation. - **Temperature Coefficient: Pmax –0.35%/°C** - The –0.35%/°C coefficient is characteristic of well-optimized mono PERC modules and results in better power retention on hot summer days. For example, at a cell temperature of 45°C, a 405 W module loses approximately 8.8 W — significantly less than the 10+ W typical of lower-grade PERC modules. - **PID Resistance and Low-Light Performance** - Certified resistance to potential-induced degradation is particularly relevant in Polish grid conditions (UPS systems, long DC string runs). The manufacturer also claims optimized low-irradiance performance — a key advantage given Poland's typical 1,600–1,700 peak sun hours per year. ## Cons - **Product Warranty of Only 15 Years** - Most Tier-1 manufacturers in this power class — including Jinko, JA Solar, and Trina — now offer a 25-year product warranty. The EGing PV STAR SERIES covers only 15 years, leaving a 10-year gap without factory protection against material defects over the typical 25-year residential system lifespan. - **PERC Technology Instead of N-Type TOPCon** - By 2025, TOPCon is becoming the market standard for new module series, offering lower LID (~1% vs. ~2% in year one for PERC) and lower annual degradation (~0.4% vs. ~0.5–0.55%). While EGing PV offers TOPCon in the STAR Pro series, the variants covered here are based exclusively on PERC, which results in lower cumulative energy yield over the system lifetime. - **Monofacial Design While Competitors Offer Bifacial** - The peer-comparable Goldi Solar GS10-M108-BF delivers the same peak power (405 W) in a bifacial configuration, typically generating 5–15% additional yield from rear-side albedo in ground-mount or light-rooftop installations. The EGing STAR SERIES is a monofacial module, limiting its energy harvest potential in such mounting scenarios. ## About this series The EGing PV STAR SERIES (108-cell module) is a solution designed for high energy yield on limited roof space. Depending on the variant, you will find technologies such as **N-Type TOPCon** or proven mono PERC cells, along with the **Half-Cell** construction, which minimizes losses and improves module performance under partial shading. In practice, this means more stable returns in typical Polish weather conditions - variable sunlight, cooler days, and in the morning. It is also worth noting the **SMBB** (busbar-free interconnection architecture), which supports better current collection from the cells and greater resistance to micro-cracks during installation and operation. The series is designed for real operational challenges, offering **resistance to PID** and optimized performance in low light conditions. This is an excellent choice for residential and commercial systems, where efficiency, aesthetics (available full-black variants), and predictable performance over years matter. ## Notable figures - Efficiency of 20.0% is 0.5pp above the \*\*PERC 0-400W\*\* median (19.4%) - At 199.7 W/m² power density, this panel generates 5.3 W/m² more per unit area than \*\*PERC 0-400W\*\* median (194.4 W/m²) - At -0.35%/°C, hot weather performance is typical for \*\*PERC 0-400W\*\* panels - #12302 for efficiency, #10419 for temperature performance out of 14005 panels ## Questions ### What warranty comes with the EGing PV STAR SERIES panels (108-cell module)? The EGing PV STAR SERIES is backed by a 15-year product warranty covering material and workmanship defects, along with a 25-year linear power output warranty. The power warranty guarantees that after 25 years of operation the module will retain at least 84.8% of its nominal rated power. EGing PV is a Bloomberg Tier 1-listed manufacturer, which provides additional assurance regarding the reliability and enforceability of these warranty commitments. ### Do the EGing PV STAR SERIES panels perform well under partial shading — for example, from a chimney or dormer window? Yes. The half-cut cell design splits each cell into two halves, which significantly reduces the impact of shading on one section of the module on the output of the remaining cells. In practice, on typical residential rooftops with chimneys, dormers, or antenna mounts — common in Polish installations — the STAR SERIES outperforms older full-cell modules under partial-shading conditions. This is a particularly valuable advantage in systems where uniform, unobstructed irradiance across the entire roof area is difficult to achieve. ### How much does a single EGing PV STAR SERIES panel weigh, and can it be installed on an older roof? The 108-cell module weighs approximately 20.2 kg and measures roughly 1722 × 1134 × 30 mm. These are standard dimensions for this class of PV module and should pose no structural issue for a typical roof truss in good condition. That said, a load-bearing assessment by a qualified structural engineer is always recommended prior to installation — particularly for buildings more than 30 years old. ### Do the EGing PV STAR SERIES panels operate efficiently in winter and under overcast conditions? Yes. The STAR SERIES is optimized for low-light performance, which is especially relevant in the Polish climate with its short winter days and frequent cloud cover. The mono PERC technology features a low temperature coefficient of approximately −0.35%/°C, meaning that on cold but sunny winter days the modules can actually deliver slightly higher output compared to peak summer temperatures — since cell efficiency improves as operating temperature drops below STC conditions. ### What is SMBB technology in the EGing PV STAR SERIES, and does it matter in practice? SMBB stands for Super Multi Busbar — a cell interconnection architecture that replaces the conventional few wide busbars with a large number of thin round wires (ribbons). This configuration improves current collection across the cell surface, increases module efficiency, and significantly enhances resistance to microcracks that can develop during installation or under mechanical loads such as snow and wind pressure. In day-to-day operation, SMBB translates to more stable long-term performance and a longer effective service life for the system. ### Is the EGing PV STAR SERIES available in an all-black version suitable for aesthetically sensitive rooftops? Yes. Within the STAR SERIES lineup (108-cell module), all-black variants are available, combining black cells with a black anodized frame and a black backsheet. This is a popular choice for installations on visible roof surfaces where visual appearance is a priority — for example, on single-family homes with ceramic or slate tiles. The electrical output and technical specifications of the all-black variant are essentially identical to those of the standard version. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/6affbdcb04fcf42-cc801a2082ba.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | +50 W, cooler, +3.1 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | -50 W, +3.0 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +3.0 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +3.0 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | Lighter, +3.0 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | Lighter, +3.0 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +3.0 pp, +5 yr warranty | | [Jetion JT440SYK(B)](https://comparepv.com/panel/jetion-jt440syk-b) | 440 W | +50 W, cooler, +2.9 pp | | [EGing PV EG-385M54-HLV (black)](https://comparepv.com/panel/eging-pv-eg-385m54-hlv-black) | 385 W | -0.3 pp | | [EGing PV EG-415M54-HLV-395W](https://comparepv.com/panel/eging-pv-eg-415m54-hlv-395w) | 395 W | +0.2 pp | | [EGing PV EG-400M54-HLV (black)](https://comparepv.com/panel/eging-pv-eg-400m54-hlv-black) | 400 W | +10 W, +0.5 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +120 W, cooler, +5.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +105 W, cooler, +4.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +115 W, cooler, +4.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +100 W, cooler, +4.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +110 W, cooler, +4.5 pp | --- Source: https://comparepv.com/panel/eging-pv-eg-390m54-hlv-black Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
