This approach not only enhances the aesthetics of the installation but, above all, significantly increases efficiency by eliminating dead zones on the panel surface. Thanks to the dense packing of cells, these panels generate more energy from the same area compared to classic solutions, making them an ideal choice for prosumers with limited roof space. A key benefit for the user is **increased resistance to shading**, as the unique internal layout allows individual module sections to operate independently. The SE6-46SC series is also characterized by excellent mechanical stability and a **minimized risk of micro-cracks**, which directly translates into the longevity of the entire photovoltaic installation. The use of **low cell operating temperature** ensures that the system maintains high efficiency even during summer heat, limiting power drops caused by component heating. This solution is dedicated to the most demanding investors who prioritize reliability and the highest system performance in all weather conditions. ## Notable figures - Efficiency of 20.2% is 1.6pp below the \*\*database\*\* median (21.8%) - 201.8 W/m² power density is 16.3 W/m² below \*\*database\*\* median (218.1 W/m²) - requires larger installation area - -0.34%/°C temperature coefficient - 0.04pp worse than \*\*database\*\* median (-0.30%/°C), expect higher hot weather losses - At 21.8 kg, this panel is 4.7 kg lighter than \*\*database\*\* median (26.5 kg) - easier handling during installation - Ranked #12039 out of 14129 panels for efficiency in the database ## Questions ### What is the shingled cell technology used in SunEvo Solar SE6-46SC panels and does it actually improve efficiency? Shingled technology overlaps thin cell strips and bonds them with conductive adhesive instead of traditional tabbing ribbons. This eliminates inactive areas on the module surface, resulting in higher power density and better use of every square centimeter. In practice, it translates to more kilowatt-hours per year from the same roof area compared to conventional PERC panels. ### Do SunEvo Solar SE6-46SC panels perform well on a roof partially shaded by a chimney or dormers? Yes, the SE6-46SC series handles partial shading better than standard modules. The shingled cell layout allows independent operation of individual module sections, so shading one section does not shut down the rest. For roofs with significant shading obstacles, adding power optimizers or microinverters will further reduce energy losses. ### What warranty comes with SunEvo Solar SE6-46SC panels and what does it cover? The manufacturer provides a 25-year product warranty covering material and workmanship defects, plus a 25-year linear power output warranty. This means SunEvo Solar guarantees a minimum power level for a full quarter century. Before purchasing, verify that the distributor has a local or European representative capable of handling warranty claims. ### What is the peak power of one SE6-46SC panel and how many do I need for a 10 kWp system? Each SE6-46SC panel has a rated peak power of 445 Wp. To build a 10 kWp system you would need approximately 23 panels (10,000 Wp ÷ 445 Wp ≈ 22.5, rounded up). The high per-panel wattage means fewer modules are required to reach a target system size, which is a clear advantage when roof space is limited. ### Do SunEvo Solar SE6-46SC panels suffer significant power loss during hot summer temperatures? The shingled architecture promotes lower cell operating temperatures by eliminating metallic tabbing ribbons that create localized hot spots. As a result, the SE6-46SC series maintains relatively high efficiency during summer heat compared to conventional modules. For the exact temperature coefficient of Pmax, check the current datasheet from the manufacturer. ### Is SunEvo Solar a Tier 1 manufacturer and what does that mean when buying SE6-46SC panels? SunEvo Solar is not currently listed among Tier 1 manufacturers according to BloombergNEF rankings. Tier 1 status primarily reflects a manufacturer's ability to finance bankable projects rather than being a direct measure of product quality. When choosing non-Tier 1 panels, pay close attention to valid IEC certifications, availability of local warranty support, and the brand's track record in the European market. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/SE-46SC-Series-0c2a0de89e3c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [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 | +45 W, +3.6 pp, +5 yr warranty | | [Luxor Solar LX-465M/182R-96+ GG](https://comparepv.com/panel/luxor-lx-465m-182r-96-gg) | 465 W | Cooler, +3.6 pp, +5 yr warranty | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | Cooler, +3.5 pp, +15 yr warranty | | [AIKO AIKO-A470-MAH54Mb](https://comparepv.com/panel/aiko-aiko-a470-mah54mb) | 470 W | +50 W, cooler, +3.4 pp | | [AIKO AIKO-A460-MAH54Mb](https://comparepv.com/panel/aiko-shenzhen-aiko-digital-energy-technology-co-ltd-aiko-a460-mah54mb-1) | 460 W | Cooler, +3.4 pp, +5 yr warranty | | [TCL Zhonghuan HSM-BD54-LA470](https://comparepv.com/panel/tcl-zhonghuan-hsm-bd54-la470) | 470 W | +50 W, cooler, +3.4 pp | | [SunEvo Solar SE6-46SC-425W](https://comparepv.com/panel/sunevo-solar-se6-46sc-425w) | 425 W | Very close match | | [SunEvo Solar SE6-46SC-430W](https://comparepv.com/panel/sunevo-solar-se6-46sc-430w) | 430 W | +10 W, +0.5 pp | | [SunEvo Solar SE6-46SC-435W](https://comparepv.com/panel/sunevo-solar-se6-46sc-435w) | 435 W | +15 W, +0.7 pp | | [SunEvo Solar SE6-46SC-440W](https://comparepv.com/panel/sunevo-solar-se6-46sc-440w) | 440 W | +20 W, +0.9 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +90 W, cooler, +4.8 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +140 W, cooler, +4.6 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +85 W, cooler, +4.5 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +85 W, cooler, +4.5 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +135 W, cooler, +4.4 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +80 W, cooler, +4.3 pp | --- Source: https://comparepv.com/panel/sunevo-solar-se6-46sc-420 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.
