The use of a **bifacial design** allows for the recovery of additional energy from both sides - particularly on light-colored roofs, on ground surfaces with gravel, or in ground-mounted systems with adequate spacing. A key advantage of this series is **dual-glass construction**, which enhances resistance to weather conditions and provides better protection for the module in demanding environments. Monocrystalline PERC technology and half-cut cell layouts support higher efficiency even under partial shading and minimize internal losses. Furthermore, multi-busbar (MBB) solutions improve current collection and enhance connection reliability. The SE6-66HBD is a good choice for PV farms, large commercial rooftops, and projects where high power density, durability, and long-term, predictable performance are desired. ## Notable figures - Efficiency of 23.2% matches the \*\*TOPCon 700-750W\*\* median - Power density of 231.8 W/m² matches the \*\*TOPCon 700-750W\*\* median - Temperature coefficient of -0.28%/°C matches the \*\*TOPCon 700-750W\*\* median - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces - Ranked #1306 out of 14005 panels for efficiency in the database ## Questions ### What is the maximum power output of the SunEvo Solar SE6-66HBD and what does it mean for my system? The SE6-66HBD delivers a peak power of 720 Wp, placing it among the highest-output large-format modules currently on the market. This means you need only about 14 panels to build a 10 kWp system, compared to roughly 20 panels at 500 W each. Higher per-panel wattage translates to fewer roof or ground mounting points, less racking hardware, and faster installation — a significant advantage in commercial rooftop and utility-scale PV projects. ### What is TOPCon technology used in the SE6-66HBD and how does it compare to older PERC cells? TOPCon (Tunnel Oxide Passivated Contact) is a next-generation monocrystalline cell architecture. In the SE6-66HBD series it achieves approximately 22.86% module efficiency — roughly 1.5 to 2 percentage points above comparable PERC modules. TOPCon also offers a lower temperature coefficient, meaning better performance on hot days, and a lower annual degradation rate of around 0.4% versus 0.55–0.6% for PERC. The cumulative yield advantage becomes especially significant over the first decade of operation. ### What warranties come with the SunEvo Solar SE6-66HBD panels? The SE6-66HBD series carries a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. The 30-year power warranty means the manufacturer commits to maintaining output above a defined degradation threshold for three full decades. This is a standard advantage of bifacial dual-glass modules and a key factor in long-term ROI modeling for commercial and utility projects. ### How does the bifacial design of the SE6-66HBD work and when does it actually pay off? A bifacial panel harvests solar energy from both the front and rear surfaces of the module. The SE6-66HBD has a bifaciality factor of approximately 80%, which on highly reflective ground cover — gravel, white roofing membrane, snow, or light-colored concrete — can yield 4–12% more annual energy compared to a standard monofacial module. The gain is greatest in ground-mounted systems with adequate ground clearance and on bright industrial rooftops. On typical dark asphalt shingles or ceramic tiles, the rear-side contribution will be negligible. ### Is SunEvo Solar a Tier 1 manufacturer and does that matter when buying SE6-66HBD panels? SunEvo Solar does not currently appear on the Bloomberg NEF Tier 1 module manufacturer list. It is important to understand that the Tier 1 classification is a bankability rating used in project finance — it does not assess technical quality or module efficiency. In practice, some lenders on externally financed large-scale projects may require additional due diligence on non-Tier 1 suppliers. For residential and smaller commercial installations, this distinction typically has little practical impact on purchasing decisions. ### Are the SE6-66HBD panels suitable for large commercial rooftops and utility-scale PV farms? Yes, the SE6-66HBD series is designed for industrial rooftop and utility-scale ground-mount applications. The 2384 × 1303 mm format, 720 Wp output, and bifacial dual-glass construction are all characteristic of utility-grade modules. However, the panel weighs approximately 37.9 kg, which requires robust racking structures and appropriate lifting equipment during installation. This series is not intended for typical residential rooftop systems. ## 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-720w 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.
