At the same 375 Wp power class, this translates into measurably higher energy yield per square meter of roof area. - **Full All-Black Aesthetics** - The anodized black frame and black backsheet (model EC375M-6-120B) create a uniform module surface — a significant advantage for installations on pitched roofs visible from street level and for ceramic tile roofs, where a white backsheet noticeably detracts from visual appeal. - **Half-Cut 120-Cell Technology — Enhanced Shade Tolerance** - Splitting cells into half-cuts reduces resistive (I²R) losses by approximately 50% and minimizes partial-shading losses through the independent operation of each module half. The 120-cell configuration, combined with an extended MC4 cable, simplifies installation in both landscape and portrait orientations. - **High Mechanical Resistance — 5,400 Pa Snow Load** - Certified snow load tolerance of 5,400 Pa and wind load tolerance of 2,400 Pa (IEC 61215, IEC 61730) are values consistent with premium-class modules and are well-suited to Polish winter conditions and steep-pitch roof installations. - **Polish Manufacturer CORAB — Local Support Since 1991** - CORAB has been active in the market for over 30 years and backs its modules with a warranty serviced by a Poland-based entity, eliminating the risk of lengthy claims procedures with Asian factories. Polish-language technical support and availability through domestic PV distributors are a practical advantage for prosumer installers. ## Cons - **Lower Efficiency Than JS Solar in This Segment** - The JS Solar JSHC166M120 achieves 21.3% efficiency at the same 375 Wp power class, compared to 20.59% for the ENCOR EC — a gap of 0.71 percentage points. For a 10 kWp system, this equates to approximately 0.35 m² of additional roof area required for equivalent energy production. - **80.2% Power Retention After 25 Years — Below TOPCon Standard** - The linear power warranty guarantees 80.2% of nominal power output after 25 years, corresponding to a degradation rate of approximately 0.79%/year. N-type TOPCon modules (e.g., newer ENCOR EC-N variants) guarantee 87–90% after 25 years at 0.40–0.45%/year degradation — a difference that compounds into several percentage points of higher annual yield in the later years of system life. - **12-Year Product Warranty — Segment Minimum** - A 12-year product warranty sits at the lower bound of current market standards; several Tier-1 manufacturers (Jinko Solar, LONGi) now offer 15-year product warranties at comparable purchase prices. ## About this series ENCOR EC series panels stand out from the competition through the combination of **monocrystalline Half-Cut cell technology** with a thoughtful design tailored to Polish climate conditions. Half-Cut cells split each cell in half, which significantly reduces current losses and improves resistance to partial shading - particularly important for installations on roofs with complex geometry or shading elements. The series is available in a **full-black aesthetic** variant with a black frame and black backsheet, which blends seamlessly into the architecture of modern buildings and roof tiles. Newer models designated with N feature advanced **TOPCon N-Type technology**, characterized by a lower temperature coefficient and slower degradation over time - which translates into genuinely higher energy yields throughout the entire lifecycle of the installation. A practical convenience is the **extended connection cable** with MC4 connectors, enabling flexible mounting in both landscape and portrait orientation without additional accessories. High mechanical resistance to snow and wind loads, confirmed by IEC 61215 and IEC 61730 certifications, makes ENCOR EC a **reliable choice** for installers and prosumers seeking a solid module with Polish technical support and a long-term linear warranty. ## Notable figures - Efficiency of 20.6% is 1.1pp above the \*\*PERC 0-400W\*\* median (19.4%) - At 205.8 W/m² power density, this panel generates 11.4 W/m² more per unit area than \*\*PERC 0-400W\*\* median (194.4 W/m²) - At -0.36%/°C, hot weather performance is typical for \*\*PERC 0-400W\*\* panels - Ranked #11174 out of 14005 panels for efficiency in the database ## Questions ### What warranty does the ENCOR EC series come with? ENCOR EC panels include a 12-year product warranty and a 25-year linear power warranty. The manufacturer guarantees a specified performance level for a quarter century, which is critical when calculating the return on investment of a photovoltaic system. Because ENCOR is headquartered in Poland, warranty claims are straightforward for domestic installers and prosumers. ### Do ENCOR EC panels perform well under partial shading? Yes, the half-cut cell technology used in the ENCOR EC series splits each cell in half, significantly reducing resistive losses under partial shading. This is a key advantage for rooftop installations near chimneys, dormers, antennas, or neighboring buildings. Because each half-cell carries lower current, shading on one section has minimal impact on the output of the rest of the module. ### What is the difference between ENCOR EC N models and the standard EC series? Models with the N designation use TOPCon N-Type cell technology, which delivers a lower temperature coefficient and slower long-term degradation compared to standard monocrystalline cells. In practice, this means higher energy yields over the full system lifetime, especially on hot summer days when elevated cell temperatures would otherwise reduce output more noticeably in conventional modules. ### Are ENCOR EC panels available in an all-black version for modern homes? Yes, the ENCOR EC series comes in a full black aesthetic variant with a black frame and black backsheet. This option integrates seamlessly with modern roofing tiles, slate, and contemporary architecture where visual appearance is as important as performance. Choosing the all-black variant does not compromise any technical specifications or power output. ### What is the maximum power output of an ENCOR EC panel, and how many modules are needed for a typical home system? ENCOR EC panels reach up to 375 Wp. A typical 6 kWp residential system requires about 16 modules, while a 10 kWp system needs roughly 27. Thanks to monocrystalline half-cut cells, the panels maintain high efficiency under diffuse irradiance conditions typical of Central European climates in autumn and winter. ### Can ENCOR EC panels be installed in both landscape and portrait orientation? Yes, the extended MC4 connection cable included with every ENCOR EC module allows flexible installation in both landscape and portrait orientation without purchasing additional cable extensions. Installers particularly appreciate this feature on roofs with non-standard geometry or limited space for cable routing, as it reduces both installation time and balance-of-system costs. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/Karta_produktu_Corab_Encor_ec375m-6-120b_pl-f87d5e82c716.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | Cooler, lighter, +2.6 pp | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | Cooler, lighter, +2.6 pp | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | Lighter, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | Lighter, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Lighter, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | Lighter, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | Lighter, +2.4 pp, +5 yr warranty | | [Gamko New Energy GKA210M380W (1/2\*4\*19)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19) | 380 W | Lighter, +2.4 pp, +5 yr warranty | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | Cooler, +2.0 pp, +15 yr warranty | | [Maxeon SPR-MAX3-425-R](https://comparepv.com/panel/maxeon-spr-max3-425-r) | 425 W | Cooler, +1.8 pp, +15 yr warranty | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +135 W, cooler, +4.4 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +120 W, cooler, +4.2 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +130 W, cooler, +4.1 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +115 W, cooler, +3.9 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +125 W, cooler, +3.9 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +125 W, cooler, +3.9 pp | --- Source: https://comparepv.com/panel/encor-ec375m-6-120b Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
