Thanks to the use of a **bifacial double glass** design, these panels effectively utilize light reflected from the ground, which significantly increases the total energy yield compared to traditional monofacial modules. The use of SMBB technology optimizes current flow and reduces the risk of micro-cracks, which directly translates to **exceptional mechanical durability** and stable operation over decades. These modules effectively solve the problem of efficiency loss at high temperatures thanks to a **low temperature coefficient**, making them an ideal choice for the increasingly warm Polish summers. The SE6-66HBD series is primarily dedicated to demanding commercial installations and large photovoltaic farms, where maximizing return on investment and achieving the lowest cost of energy (LCOE) is of key importance. What distinguishes it from competitors- solutions is **minimal light-induced degradation** (LID), which guarantees investors safety and full predictability of yields over a long-term horizon. It is a choice for professionals focusing on innovations that realistically work for higher profit without any quality compromises. ## Notable figures - Efficiency of 23.2% matches the \*\*TOPCon 700-750W\*\* median - At 231.8 W/m² power density, roof space requirements are typical for \*\*TOPCon 700-750W\*\* panels - At -0.28%/°C, hot weather performance is typical for \*\*TOPCon 700-750W\*\* panels - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - In the top 9% for efficiency among all TOPCon panels ## Questions ### What is the maximum power output of SunEvo Solar EVO 6N panels — do SE6-66HBD modules really reach 720 Wp? Yes, the top-tier modules in the SE6-66HBD series achieve a peak power of up to 720 Wp under Standard Test Conditions (STC). This is typical for large-format utility-scale modules based on N-type TOPCon cells. Higher per-module wattage reduces the number of panels needed per unit area and lowers Balance of System (BoS) costs, directly improving the project's LCOE. ### What is TOPCon technology and why choose it in the EVO 6N series? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology offering higher efficiency and lower degradation than standard PERC cells. In the EVO 6N series this means minimal Light-Induced Degradation (LID), better performance under diffuse irradiance, and stable output throughout the 30-year power warranty period. For commercial and utility-scale solar farms it translates into a measurably lower LCOE over the full investment horizon. ### What warranties are included with SunEvo Solar EVO 6N (SE6-66HBD) panels? The EVO 6N series comes with a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty. The manufacturer guarantees a specified minimum percentage of original rated output for three decades — standard conditions for commercial-grade modules that typically satisfy project finance requirements from lenders in the renewable energy sector. ### Does the bifacial double glass design of the SE6-66HBD actually increase energy yield, and by how much? Yes, the bifacial double glass construction allows EVO 6N modules to harvest not only direct front-side irradiance but also albedo light reflected from the ground. With white gravel or light concrete surfaces, bifacial gain typically ranges from 5–15% compared to monofacial panels, depending on tilt angle and ground surface reflectivity. The benefit is most pronounced on ground-mounted utility-scale solar farms with an optimized albedo surface. ### Is SunEvo Solar a Tier 1 manufacturer and are EVO 6N panels bankable? SunEvo Solar is not currently listed on Tier 1 rankings published by Bloomberg NEF or PV-Tech. For bank-financed projects, lenders may require additional technical and financial due diligence or yield insurance. This does not necessarily indicate poor product quality, but it is advisable to consult a financial advisor or independent engineer before specifying these modules for a large commercial installation. ### Are SunEvo Solar EVO 6N panels suitable for large utility-scale solar farms in Poland? Yes, the SE6-66HBD series is designed for utility-scale and commercial installations. The 720 Wp rating and large-format frame are compatible with standard racking systems used on Polish solar farms. The low temperature coefficient supports stable output on hot summer days, and the 30-year power warranty covers a typical renewable energy project horizon. MPPT compatibility with the selected inverter and the overall electrical design should be verified before procurement. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/evo6n-n-type-topcon-bifacial-double-glass-700-720w-solar-mou-9ef6011a0554.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | -40 W, lighter, +2.0 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -45 W, lighter, +1.8 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +1.8 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | -25 W, lighter, +1.7 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -50 W, lighter, +1.6 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -50 W, lighter, +1.6 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -50 W, lighter, +1.6 pp | | [SunEvo Solar SE6-66HBD-700W](https://comparepv.com/panel/sunevo-solar-se6-66hbd-700w) | 700 W | -20 W, -0.7 pp | | [SunEvo Solar SE6-66HBD-705](https://comparepv.com/panel/sunevo-solar-se6-66hbd-705) | 705 W | -15 W, -0.5 pp | | [SunEvo Solar SE6-66HBD-710](https://comparepv.com/panel/sunevo-solar-se6-66hbd-710) | 710 W | -10 W, -0.3 pp | | [SunEvo Solar SE6-66HBD-715](https://comparepv.com/panel/sunevo-solar-se6-66hbd-715) | 715 W | Very close match | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +85 W, cooler, +1.9 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +80 W, cooler, +1.7 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +75 W, cooler, +1.6 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +70 W, cooler, +1.4 pp | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | +40 W, cooler, +1.3 pp | --- Source: https://comparepv.com/panel/sunevo-solar-se6-66hbd-720 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.
