The use of **N-type TOPCon cells** helps minimize typical power losses over time and maintain stable performance in the long term, which is beneficial for both prosumers and commercial investors. The **bifacial** design allows for efficient utilization of reflected light from the ground - a significant advantage on flat roofs, ground-mounted systems, and anywhere where a clear surface can be maintained beneath the modules. The module utilizes a **half-cut cell** design, which improves resilience to partial shading and supports even performance throughout the entire string. Furthermore, the **anti-reflective glass** reduces reflections and facilitates energy harvesting in challenging lighting conditions. The SE6R-66HBD is a good choice for PV farms, large industrial rooftops, and projects where maximizing yield and reliability are prioritized over compromises in design. ## Notable figures - Efficiency of 23.1% matches the \*\*TOPCon 600-650W\*\* median - At 231.4 W/m² power density, this panel generates 3.7 W/m² more per unit area than \*\*TOPCon 600-650W\*\* median (227.7 W/m²) - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 600-650W\*\* median - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - #1554 for efficiency, #6152 for temperature performance out of 14129 panels ## Questions ### What are N-type TOPCon cells in the SE6R-66HBD series and why do they matter? TOPCon (Tunnel Oxide Passivated Contact) is an advanced N-type silicon cell architecture. Compared to mainstream PERC, TOPCon achieves higher conversion efficiency (the SE6R-66HBD series reaches approx. 22.68%) and a lower temperature coefficient of -0.30%/°C, meaning less power loss on hot days. N-type cells also exhibit significantly lower LID degradation, so the module's rated power declines more slowly during the first years of operation. ### Does the bifacial SE6R-66HBD panel work well on a pitched roof? Bifacial modules work on any roof type, but their rear-side advantage is greatest when reflected light can reach the back surface. On a typical pitched roof with dark tiles, the bifacial gain is minimal (1-3%). The SE6R-66HBD series reaches its full bifacial potential on ground-mounted systems, white or light-colored flat rooftops, and structures with a bright membrane beneath. On pitched roofs, the main reason to choose this series is its high 625 W output and efficiency, not bifaciality. ### What warranty does the SunEvo Solar SE6R-66HBD come with? The manufacturer provides a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means the panel is guaranteed to maintain the declared percentage of its initial rated power according to the degradation curve in the datasheet. This is one of the longer warranty programs available for TOPCon modules - make sure installation is performed by a certified installer, as installation errors can void the warranty. ### Does the SE6R-66HBD perform well in winter and low-light conditions? Yes. The low temperature coefficient (-0.30%/°C) reduces power loss on hot summer days, but also makes the module well-suited to the temperature swings typical of Central European climates. In overcast and diffuse-light conditions, N-type TOPCon cells show slightly better low-light response than older PERC cells, resulting in higher energy yield on cloudy days. The half-cut cell layout further reduces losses under partial shading. ### Which inverters are compatible with the 625 W SE6R-66HBD series? 625 W modules require an inverter with a sufficiently high MPPT input voltage - typically at least 600-800 V DC. The SE6R-66HBD series is compatible with mainstream grid-tied inverters (SMA, Fronius, Huawei, SolarEdge, Growatt, and others) that support high-wattage modules. Before purchasing, check the inverter datasheet for maximum string voltage and align the number of modules per string with the MPPT voltage range of your chosen device. ### SunEvo Solar is not a Tier 1 manufacturer - is that a concern when buying the SE6R-66HBD? Tier 1 lists (e.g., Bloomberg NEF) primarily assess a manufacturer's financial standing and bankability, not product quality. SunEvo Solar is a Chinese manufacturer with IEC- and TÜV-certified modules, and the SE6R-66HBD series is listed in the ENF Solar and ComparePV databases with full documentation. When purchasing, verify the warranty insurance policy, the availability of a local distributor, and the manufacturer's claims history. For large commercial installations, additional warranty insurance is worth considering. ## 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, +2.1 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +50 W, lighter, +1.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +1.9 pp | | [WINAICO WST-675BKX72-A2](https://comparepv.com/panel/winaico-wst-675bkx72-a2) | 675 W | +50 W, cooler, +1.9 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +45 W, lighter, +1.7 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +45 W, lighter, +1.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | Cooler, lighter, +1.7 pp | | [SunEvo Solar SE6R-66HBD-600W](https://comparepv.com/panel/sunevo-solar-se6r-66hbd-600w) | 600 W | -25 W, -0.9 pp | | [SunEvo Solar SE6R-66HBD-605W](https://comparepv.com/panel/sunevo-solar-se6r-66hbd-605w) | 605 W | -20 W, -0.7 pp | | [SunEvo Solar SE6R-66HBD-610W](https://comparepv.com/panel/sunevo-solar-se6r-66hbd-610w) | 610 W | -15 W, -0.6 pp | | [SunEvo Solar SE6R-66HBD-615W](https://comparepv.com/panel/sunevo-solar-se6r-66hbd-615w) | 615 W | -10 W, -0.4 pp | | [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 | +55 W, lighter, +2.1 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +75 W, cooler, +1.9 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +70 W, cooler, +1.8 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +45 W, cooler, +1.7 pp | --- Source: https://comparepv.com/panel/sunevo-solar-se6r-66hbd-625w 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.
