Space saver, weak in heat
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.

In a direct peer comparison, the ENCOR EC375 delivers 20.59% module efficiency — 0.59 percentage points above the Boviet VEGA (20%) and 0.39 pp above the Boviet GAMMA (20.2%). At the same 375 Wp power class, this translates into measurably higher energy yield per square meter of roof area.
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.
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.
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.
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.
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.
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.
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.
- 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
