This allows more power to be harvested from limited roof space without any technological compromise. - **30-Year Linear Power Warranty ≥87.4%** - The manufacturer guarantees degradation of ≤1% in Year 1 and ≤0.40%/year for the subsequent 29 years, resulting in a minimum of 87.4% of rated power after 30 years. Standard Tier-1 PERC panels (e.g., JA Solar, Trina) typically offer 25-year warranties with an 84.8% floor — STAR Pro delivers both a longer coverage period and a higher minimum power threshold. - **Favorable Temperature Coefficient of -0.30%/°C** - The temperature coefficient of -0.30%/°C outperforms the typical range of legacy P-type PERC cells (-0.35 to -0.45%/°C), meaningfully reducing power losses on hot days. EGing reports an approximately 3% increase in annual energy yield compared to P-type modules under equivalent climatic conditions. - **Half-Cut + SMBB Technology for Challenging Roof Layouts** - The combination of half-cut cells and super multi-busbar (SMBB) technology reduces resistive losses and limits the impact of partial shading on the entire string. In practical residential installations featuring chimneys or dormers, effective shading affects fewer cells than in a conventional 60-cell full-cell module. - **20+ Years of Manufacturing Experience and Bankable Status** - EGing PV has been in operation since 2003 and is the first publicly listed pure-play module manufacturer on the Shanghai Stock Exchange (SHA: 600537). Its Tier-1/bankable status confirms its eligibility to support bank-financed projects on a non-recourse basis. ## Cons - **Significant Manufacturer Financial Risk** - In 2024, EGing PV reported a net loss of approximately RMB 2.09 billion (~USD 288 million), accompanied by a 57% year-over-year revenue decline; its TOPCon facilities in Chuzhou (7.5 GW of capacity) were fully suspended in 2025 amid module capacity utilization of approximately 35%. Despite the completion of a pre-restructuring process and the securing of RMB 819 million in new financing (April 2026), the severe deterioration in profitability represents a material risk factor for honoring the 30-year power warranty — particularly for installations with long payback horizons. ## About this series The EGing PV STAR Pro SERIES are modules based on **N-type TOPCon cells**, designed for high productivity in Polish conditions - even when the weather is unfavorable. Thanks to **half-cut technology** and **SMBB (multi-busbar)** solutions, the panels better limit internal losses and operate more stably under partial shading, which genuinely simplifies the design of rooftop installations near chimneys, windows, or neighboring obstructions. In practice, this means more predictable yields and lower risks of underestimating energy production. The **bifacial dual-glass** versions additionally allow for utilizing reflected light, which is significant on light-colored rooftops, ground installations, or industrial setups. The series also stands out for its **PID resistance** and optimized performance in low-light conditions, translating to better profitability during transitional seasons. It is an excellent choice for premium home installations, commercial rooftops, and projects where high efficiency, durability, and operational safety are key. ## Notable figures - At 21.8% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - At 217.6 W/m² power density, roof space requirements are typical for \*\*TOPCon 400-450W\*\* panels - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - At 20.2 kg, this panel is 1.8 kg lighter than \*\*TOPCon 400-450W\*\* median (22.0 kg) - easier handling during installation - #7285 for efficiency, #6093 for temperature performance out of 14005 panels ## Questions ### What warranty is offered on EGing PV STAR Pro SERIES panels? EGing PV provides a 12-year product warranty (covering material and manufacturing defects) and a 30-year linear power output warranty on the STAR Pro series. This means that after 30 years, the panel should still produce at least 87.4% of its nominal output power. Warranty claims are handled through an authorized distributor or directly with the manufacturer. ### Do EGing PV STAR Pro SERIES panels perform well in winter and under overcast conditions? Yes. N-type TOPCon cells feature a low temperature coefficient (approx. -0.30%/°C), which means smaller power losses during freezing temperatures compared to older P-type modules. The STAR Pro series is also optimized for low-irradiance conditions, so even on overcast autumn and winter days the installation generates a measurable amount of energy. ### What do half-cut cell technology and SMBB offer in the STAR Pro panels, and does it really matter when shading occurs? In the STAR Pro series, cells are cut in half and additionally interconnected with multiple thin wires (SMBB, multi-busbar). If part of the panel falls into the shadow of a chimney, dormer, or antenna, the power loss is confined to the shaded section only, rather than affecting the entire module. In practice, on typical residential rooftops this can increase annual energy yield by several to more than ten percent compared to full-cell modules without SMBB. ### Is the EGing PV STAR Pro SERIES available in a bifacial version? EGing PV does offer a bifacial dual-glass variant for the STAR Pro series; however, the standard product line available in Poland consists of monofacial modules. Bifacial versions are worth considering for ground-mount installations or on light-colored flat roofs, where reflected irradiance can increase energy yield by a few percent. It is advisable to confirm the availability of a specific variant with your distributor before purchase. ### What power output and efficiency do EGing PV STAR Pro SERIES panels achieve, and who are they intended for? Peak power output for the 72-cell models reaches up to 580 Wp, with a conversion efficiency of approximately 22.45%. These are top-tier specifications within the prosumer and commercial segments. The series is well suited for premium residential installations, commercial rooftops, and larger projects where maximizing energy yield from a limited roof area is a priority. ### Is EGing PV a reliable manufacturer, and do the STAR Pro panels meet quality standards? EGing PV is a Chinese manufacturer that has been operating since 2003 and holds Tier 1 status according to the BloombergNEF ranking, indicating financial stability and supply reliability. STAR Pro series panels carry IEC certifications, and the N-type TOPCon cells are resistant to PID (Potential Induced Degradation). This is particularly important in Poland, where humidity and fluctuating temperatures can accelerate the aging of lower-quality modules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/e0bbef22edcd72e-02a5442edfd9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +50 W, +2.2 pp, +15 yr warranty | | [Just Solar JST-EDMH-(445-465)W-TD (465W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-465w-class) | 465 W | +40 W, +2.0 pp, +5 yr warranty | | [JA Solar JAT54S40-475/LR](https://comparepv.com/panel/ja-solar-jat54s40-475-lr) | 475 W | +50 W, +2.0 pp, +5 yr warranty | | [Tongwei TWMNH-48HW475](https://comparepv.com/panel/tongwei-solar-twmnh-48hw475) | 475 W | +50 W, +2.0 pp, +5 yr warranty | | [Astronergy CHSM48RN(DG)/F-BH-475](https://comparepv.com/panel/astronergy-chint-new-energy-technology-co-ltd-chsm48rn-dg-f-bh-475) | 475 W | +50 W, +2.0 pp, +5 yr warranty | | [AIKO AIKO-A475-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a475-mce54mw) | 475 W | +50 W, +2.0 pp, +5 yr warranty | | [AIKO AIKO-A475-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a475-mah54mw) | 475 W | +50 W, +2.0 pp, +5 yr warranty | | [EGing PV EG-385M54-HLV (black)](https://comparepv.com/panel/eging-pv-eg-385m54-hlv-black) | 385 W | -40 W, hotter, -2.1 pp | | [EGing PV EG-390M54-HLV (black)](https://comparepv.com/panel/eging-pv-eg-390m54-hlv-black) | 390 W | -35 W, hotter, -1.8 pp | | [EGing PV EG-415M54-HLV-395W](https://comparepv.com/panel/eging-pv-eg-415m54-hlv-395w) | 395 W | -30 W, hotter, -1.5 pp | | [EGing PV EG-400M54-HLV (black)](https://comparepv.com/panel/eging-pv-eg-400m54-hlv-black) | 400 W | -25 W, hotter, -1.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +85 W, cooler, +3.2 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +70 W, +3.0 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +80 W, cooler, +2.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +65 W, +2.7 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +75 W, cooler, +2.7 pp | --- Source: https://comparepv.com/panel/eging-pv-eg-425nt54-hlv 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.
