In practice, this means fast warranty claim resolution without the need to contact an overseas support center — a significant advantage for installers and commercial investors who require a responsive turnaround time. - **Premium-Class Mechanical Durability** - The panel is certified for snow load of 5,400 Pa and wind load of 2,400 Pa, placing it above the standard minimum (2,400/2,400 Pa per IEC 61215). These ratings make the series well-suited for installations in harsh climatic conditions and on industrial facilities with demanding roof structures. - **1500 V DC System Voltage Support** - A maximum system voltage of 1,500 V DC allows for longer string configurations than in 1,000 V installations, reducing BoS costs (cabling, number of MPPT inputs) and simplifying system design — particularly beneficial in commercial and utility-scale projects. - **Low Annual Degradation of 0.55%** - After the first year (degradation \<2%), the panel loses only 0.55% of its power output annually, guaranteeing 84.8% of nominal power after 25 years. For a 10 kWp installation, this translates to tens of additional kWh per year compared to modules with a 0.7%/year degradation rate. - **Half-Cut PERC Technology and IEC 62716 Certification** - Half-cut cells reduce resistive losses and improve shadow tolerance under partial shading conditions. The IEC 62716 certification (ammonia resistance) broadens the application range to include agrivoltaic installations and livestock farming facilities. ## Cons - **21.3% Efficiency — Notable Gap to Segment Peers** - Peer comparables at the same 460 Wp power class achieve efficiencies of 23% (Risen RSM96-11-440-460BNDG, N-type TOPCon) and 23.02% (SunKean SKT440~460M12-96D4) — a difference of approximately 1.7 percentage points. With a module area of approximately 2.16 m², this means that achieving the same installed capacity with ENCOR panels requires measurably more roof space or a higher module count. - **PERC Technology — An Older Standard** - Direct competitor Risen RSM96-11 employs N-type TOPCon, which offers lower LID/LeTID rates, a better temperature coefficient, and higher efficiency. PERC remains a proven technology, but in the 460 Wp segment an increasing number of manufacturers are migrating to N-type, which may affect the perceived technological currency of this series. - **15-Year Product Warranty** - The 15-year product warranty meets the market minimum; however, peer product Risen RSM96-11 offers a 25-year product warranty in this class. For investors underwriting commercial projects with a horizon exceeding 15 years, the shorter coverage period increases exposure to out-of-pocket service costs after the warranty expires. ## About this series The ENCOR EC460M-10-120S series is a premium-class photovoltaic module based on **monocrystalline PERC half-cut cell technology**, combining high productivity with exceptional resistance to harsh weather conditions.

The ENCOR EC460M-10-120S series comes with a 15-year product warranty covering material and workmanship defects. The manufacturer also provides a 25-year linear power output warranty with an exceptionally low degradation curve, ensuring stable and predictable energy generation throughout the module's lifetime. For prosumer and commercial installations, this provides a solid foundation for return-on-investment calculations. ### Does the half-cut PERC technology in the EC460M-10-120S improve performance under partial shading? Yes. The half-cut PERC cells used in the EC460M-10-120S series split each cell into two smaller segments, reducing resistive losses and limiting the negative impact of partial shading — from chimneys, antennas, or nearby trees. The panel maintains high energy output even in diffuse light and low-irradiance conditions, making it a reliable choice for rooftops with obstructions. ### Is the ENCOR EC460M-10-120S a bifacial panel? No, the EC460M-10-120S is a monofacial module — electricity is generated solely through the front surface. It does not feature an active rear side like bifacial panels and therefore does not benefit from light reflected off the ground or mounting surface. For typical rooftop systems and most ground-mounted installations, this is a fully sufficient and well-proven solution that is also simpler to design around. ### Are the ENCOR EC460M-10-120S panels suitable for large-scale solar farms? Yes, the EC460M-10-120S series was designed with commercial installations and utility-scale PV farms in mind. Support for high system voltage enables longer string configurations, simplifying the electrical design and reducing Balance of System (BoS) costs. Certified mechanical resistance to extreme snow and wind loads makes these modules reliable in demanding climatic and terrain conditions. ### What is the peak power of the ENCOR EC460M-10-120S and is it enough for a typical home? The ENCOR EC460M-10-120S delivers a peak power output of 460 Wp under STC conditions. For a typical single-family home consuming 3,500–5,000 kWh per year, 8–12 modules are usually sufficient, depending on roof orientation and actual energy usage. The high per-unit power rating means fewer panels are needed to reach the target system capacity. ### Where is ENCOR service available and how does the EC460M-10-120S warranty claim process work? The ENCOR brand is developed by Corab, a Polish manufacturer, which means service and warranty claims are handled domestically — without the need to contact an overseas producer. Local support shortens response times and simplifies warranty procedures, providing a significant advantage for installers and investors who require efficient after-sales assistance and fast access to technical support. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/2029-corab-encor-ec460m-10-120s-karta-produktu-pl-3aa814157ae7.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +50 W, cooler, +3.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, +3.5 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +3.4 pp, +5 yr warranty | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, +3.2 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +3.2 pp, +5 yr warranty | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, +3.2 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +100 W, cooler, +3.5 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +95 W, cooler, +3.3 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +90 W, cooler, +3.1 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +80 W, cooler, +3.1 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +80 W, cooler, +3.1 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +85 W, cooler, +3.0 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | +85 W, cooler, +2.9 pp | --- Source: https://comparepv.com/panel/encor-ec460m-10-120s Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
