The ENCOR EC415M series is a line of photovoltaic modules from the Polish brand Corab, available in two technological variants tailored to different investor needs. The N-type TOPCon Bifacial variant uses double-sided cells in a glass-glass construction - the panel absorbs radiation from both the front and rear side, translating into 10 to 30% additional energy compared to traditional monofacial modules. N-type technology performs particularly well under diffuse light conditions - during fog or overcast skies it generates more current than conventional P-type cells. The variant with a black frame and half-cut cells, in turn, is designed for rooftop installations on single-family homes, where aesthetics and low power degradation over time matter. Both variants feature a linear power warranty for 30 years and fire class A, meaning the highest level of fire safety. The ENCOR EC415M series is intended both for individual prosumers and small commercial installations, and Polish distribution and service shorten lead times and simplify warranty handling.

What owners get
Domestic Distribution and Door-to-Door Service

Corab S.A. — the manufacturer behind the ENCOR brand — operates a door-to-door service model backed by a nationwide network of field technicians in Poland. This significantly reduces response times for warranty claims and eliminates the need to ship modules abroad for servicing, a genuine competitive advantage over most Asian Tier-1 brands available on the Polish market.

21.25% Efficiency in the 415 Wp Segment

The module matches its direct peer comparables: LEDVANCE M395~415P54LM-BF-F3 (21.25%), Aptos Solar DNA 108-Monofacial (21.25%), and AE Solar AURORA AE MD-108 (21.28%). It ranks in the upper efficiency band for the 108-cell half-cut format and holds its own against European competitors.

Half-Cut Cells and 1500 V DC System Voltage

Half-cut cell technology reduces internal current by approximately 50%, lowering resistive losses and improving partial-shading tolerance. The 1500 V DC maximum system voltage enables longer strings, reducing BoS wiring costs in commercial and utility-scale installations.

High Mechanical Resistance: 5400 / 2400 Pa

The module withstands snow loads of 5400 Pa and wind loads of 2400 Pa, exceeding the standard IEC 61215 requirements of 2400 / 2400 Pa. This specification is particularly relevant in the Polish climate, where heavy snow accumulation on pitched roofs is common.

Established Manufacturer — 35 Years in Renewable Energy

Corab S.A. has been operating since 1991 and is Poland's largest manufacturer of PV mounting structures, offering a complete ENCOR ecosystem encompassing modules, inverters, and energy storage. Its long track record substantially reduces the risk of warranty orphaning — a real concern with lesser-known brands.

Trade-offs
12-Year Product Warranty — Below Tier-1 Standard

The product warranty stands at 12 years, whereas leading Tier-1 manufacturers — including JA Solar, Trina Solar, Canadian Solar, and Risen — offer 15 years as standard. For systems with a planned service life of 25+ years, this gap may be consequential if mechanical defects emerge between years 13 and 15.

84.8% Power Retention After 25 Years — Typical P-Type PERC Performance

The declared output after 25 years is 84.8% (year 1: <2%; subsequent years: 0.55%/year), consistent with typical P-type PERC degradation profiles. By comparison, N-type TOPCon modules — including the bifacial variant of the same EC415M series — generally deliver ≥87–88% power retention after 25 years at an annual degradation rate of approximately 0.40%.

Common questions

6 answered
What warranty does the ENCOR EC415M panel come with, and what does it cover?
The ENCOR EC415M series comes with a 12-year product warranty covering material and manufacturing defects, along with a 25-year linear power output warranty that defines the maximum allowable performance degradation over time. The modules carry fire class A certification, the highest fire safety rating. Warranty service is handled by Polish distributor Corab, significantly shortening claim response times compared to panels imported without local support.
Is the black-frame ENCOR EC415M panel a good aesthetic fit for a sloped residential roof?
Yes, the black-frame variant of the ENCOR EC415M is specifically designed for residential rooftop installations. The black frame combined with dark half-cut cells creates a uniform, low-profile appearance that blends well with dark roof tiles or metal roofing. It is the right choice for homeowners who want both solid energy output and a visually clean roofline.
What are half-cut cells in the ENCOR EC415M and why do they matter?
Half-cut cell technology splits each cell in two, reducing internal resistance and heat-related losses. The practical benefit is lower power loss under partial shading from chimneys or dormers, and slower long-term degradation. An ENCOR EC415M panel with half-cut cells produces more annual energy than a conventional full-cell module with the same 415 Wp nameplate power rating.
How quickly can I get warranty service for ENCOR EC415M panels if something goes wrong?
ENCOR EC415M is a product of Polish brand Corab with domestic distribution and service infrastructure. This means no need to contact an overseas manufacturer, faster response times, and warranty claims handled entirely in Poland. In practice, module replacement or claim resolution is significantly quicker than for panels sourced directly from Asia without a local authorized service network.
How much energy can a system built with 415 Wp ENCOR EC415M panels generate annually?
A single ENCOR EC415M module rated at 415 Wp will produce approximately 415 to 460 kWh per year at a typical Polish location with around 1000-1100 kWh/kWp of annual irradiation. A 10-panel system (approx. 4.15 kWp) typically covers 60-80% of an average household's annual electricity consumption, depending on roof orientation, tilt angle, and actual energy usage.
What is the difference between the N-type TOPCon Bifacial variant and the black-frame variant in the ENCOR EC415M series?
The N-type TOPCon Bifacial variant uses bifacial cells in a glass-glass construction, harvesting an additional 10-30% of energy from albedo reflections off the ground or rooftop surface, making it ideal for ground-mount or flat-roof installations. The black-frame half-cut variant prioritizes aesthetics and low long-term degradation for sloped residential rooftops. Both variants share the same 415 Wp rating, 25-year power warranty, and fire class A certification.
