The innovative use of rectangular cells allows for significantly better power density, which directly translates to maximizing yields from every square meter of surface area. A key distinguishing feature of this series is the **bifacial double-sided design**, which, combined with double glass, ensures additional energy yield from reflected radiation and extreme durability in harsh conditions. This solution effectively eliminates the problem of light-induced degradation, guaranteeing stable system operation for decades. These panels are primarily dedicated to modern solar farms and large commercial installations where the priority is the lowest cost of energy production. Compared to the competition, this model stands out with an **excellent temperature coefficient** and high efficiency in diffused light conditions, which is crucial in the Polish climate zone. By investing in the EVO 6R series, users gain **the highest resistance to mechanical loads** and a modern design that combines aesthetics with uncompromising technology, ensuring energy security at the highest level. ## Notable figures - Efficiency of 22.8% matches the \*\*TOPCon 600-650W\*\* median - At 227.7 W/m² power density, roof space requirements are typical for \*\*TOPCon 600-650W\*\* panels - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 600-650W\*\* panels - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - In the top 22% for efficiency among all TOPCon panels ## Questions ### What warranty comes with the SunEvo Solar EVO 6R SE6R-66HBD panels? The EVO 6R SE6R-66HBD series carries a 25-year product warranty covering defects in materials and workmanship, plus a 30-year linear power output warranty. The N-type TOPCon cells deliver low degradation rates, and the double-glass construction adds structural durability. The 30-year power warranty is one of the longest available in the utility-scale segment, reflecting the manufacturer's confidence in long-term module performance. ### How does the TOPCon cell technology in the EVO 6R differ from standard PERC modules? The N-type TOPCon cells used in the EVO 6R SE6R-66HBD have a lower temperature coefficient (-0.30%/°C) and significantly reduced light-induced degradation (LID) compared to PERC technology. This translates to higher energy yield on hot days and a more stable power output across the module's lifetime. The SE6R-66HBD-625W achieves over 22.6% module efficiency, putting it at the top of the utility-scale class. ### What real-world benefit does the bifacial design of the EVO 6R SE6R-66HBD deliver? The bifacial EVO 6R captures direct irradiance on the front side and reflected irradiance on the rear side. With a bifaciality factor of approximately 80%, ground-mounted installations on reflective surfaces such as white gravel or snow can expect a 4-12% increase in annual energy yield compared to monofacial modules. The double-glass encapsulation protects both active surfaces over the full 30-year warranty period. ### Is the SunEvo Solar EVO 6R 625 Wp a good fit for a utility-scale PV farm? Yes, the EVO 6R SE6R-66HBD is purpose-built for utility-scale solar farms and large commercial rooftops. At 625 Wp per module, it reduces the total module count and lowers balance-of-system (BoS) costs per megawatt. The -0.30%/°C temperature coefficient and strong low-irradiance performance help maintain a competitive LCOE in climates with significant cloud cover, such as Central Europe. ### Is SunEvo Solar a Tier 1 manufacturer and is it a reliable choice for large projects? SunEvo Solar is not currently listed as a Tier 1 manufacturer by Bloomberg NEF. It is worth noting that Tier 1 classification reflects financial capacity and bankability in large-scale project finance rather than direct product quality. The EVO 6R SE6R-66HBD series can be independently verified through ENF Solar and ComparePV. For large investments, it is advisable to review current certifications, IEC test reports, and project references before committing. ### How does the EVO 6R SE6R-66HBD perform in cold weather and low-light conditions? The N-type TOPCon cells in the EVO 6R carry a temperature coefficient of -0.30%/°C, meaning the module produces more power on cold, clear days than older PERC technology. The double-glass, bifacial construction performs well under diffuse irradiance - a key advantage in northern and Central European climates with frequent overcast skies. The rigid glass-glass laminate also provides superior resistance to snow loads and mechanical stress over the module's lifetime. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/evo-6r-600-625w-n-type-topcon-bifacial-double-glass-solar-mo-75665fe3cba7.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +2.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +2.2 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +2.0 pp | | [Longi Solar LR8-66HVD-665M](https://comparepv.com/panel/longi-lr8-66hvd-665m) | 665 W | +50 W, cooler, +1.9 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (665W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-665w-class) | 665 W | +50 W, cooler, +1.9 pp | | [Huayao HY665-B144DSS](https://comparepv.com/panel/huayao-hy665-b144dss) | 665 W | +50 W, lighter, +1.9 pp | | [Sunpro Power SPDG665-BC132R12](https://comparepv.com/panel/sunpro-spdg665-bc132r12) | 665 W | +50 W, cooler, +1.9 pp | | [SunEvo Solar SE6R-66HBD-600W](https://comparepv.com/panel/sunevo-solar-se6r-66hbd-600w) | 600 W | -15 W, -0.6 pp | | [SunEvo Solar SE6R-66HBD-605W](https://comparepv.com/panel/sunevo-solar-se6r-66hbd-605w) | 605 W | -10 W, -0.4 pp | | [SunEvo Solar SE6R-66HBD-610W](https://comparepv.com/panel/sunevo-solar-se6r-66hbd-610w) | 610 W | Very close match | | [SunEvo Solar SE6R-66HBD-620W](https://comparepv.com/panel/sunevo-solar-se6r-66hbd-620w) | 620 W | Very close match | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +65 W, lighter, +2.4 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +60 W, lighter, +2.2 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +85 W, cooler, +2.2 pp | | [WINAICO WST-675BKX72-A2](https://comparepv.com/panel/winaico-wst-675bkx72-a2) | 675 W | +60 W, cooler, +2.2 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +80 W, cooler, +2.1 pp | --- Source: https://comparepv.com/panel/sunevo-solar-se6r-66hbd-615 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
