The Lina Energy LEPV 120 HALF-CUT series consists of monocrystalline modules with a half-cut (120 cells) architecture, designed for stable operation of the installation in real roof conditions - even when partial shading from chimneys, trees, or dormer windows occurs. Dividing the cells in half reduces losses associated with current flow, and the arrangement with 3 bypass diodes helps maintain energy production under uneven sunlight.

This series uses tempered glass with an anti-reflective coating, which improves the utilization of diffuse light - important in the Polish climate, where many days of the year have cloudy skies. The modules also have a connection box with IP68 protection, which increases resistance to moisture, dust, and long-term outdoor operation.

The LEPV 120 HALF-CUT is a good choice for single-family homes, small businesses, and prosumer installations, where consistent yields, durability, and easy integration with standard inverters and mounting equipment are important.

What owners get
21.17% efficiency, above peer group

The module achieves 21.17% efficiency, exceeding comparable 340 Wp panels - MWG Mono (20.12%), Resun RS6K-M (20.15%), and even Panasonic HIT+.+ N340 (20.3%). This is the highest result within the 340 Wp peer comparison group.

Half-cut architecture with 3 bypass diodes

Splitting cells into 120 half-cells reduces resistive losses and improves heat dissipation, while the 3-bypass-diode layout maintains power output under partial shading from chimneys or dormers - a common condition on Polish single-family roofs.

AR-coated glass for diffuse light

Tempered glass with an anti-reflective coating improves utilization of diffuse irradiance, which is practically relevant in Poland's climate with a high number of overcast days per year.

IP68-rated junction box

IP68 ingress protection offers higher resistance to moisture and dust than the commonly used IP65 standard, supporting long-term reliability in outdoor installations.

25-year power warranty

The 25-year linear power warranty and 20-year product warranty match the market standard for monocrystalline modules from 2020 and provide a predictable basis for yield calculations over the full lifetime of the installation.

Trade-offs
Production discontinued in 2024

The LEPV 120 HALF-CUT series was discontinued (released 2020, ended 2024), meaning limited availability of identical modules for system expansion and potential difficulties with warranty service over the 25-year power warranty period.

Manufacturer outside BNEF Tier-1 list

Lina Energy (headquartered in the UK, founded 2017) does not appear on the current BloombergNEF Tier-1 list, unlike brands such as Panasonic in the peer set. This may affect project bankability and bank financing terms.

No bifacial variant

The series does not offer bifacial technology (is_bifacial: false), while the manufacturer's portfolio includes bifacial models (e.g., LEPV 144 BIFACIAL) capable of generating additional albedo-driven yield - this potential remains untapped in this series.

About the LEPV 120 HALF-CUT series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

Is the Lina Energy LEPV 120 HALF-CUT series still available for purchase?
The LEPV 120 HALF-CUT series has been discontinued and is no longer actively sold by Lina Energy. Some remaining stock may still be available through distributors, but supply is limited. If you are planning a new installation, it is worth asking your supplier about a current replacement with comparable power output and half-cut cell technology.
What warranty does the Lina Energy LEPV 120 HALF-CUT come with?
Lina Energy provides a 20-year product warranty covering the modules themselves, along with a 25-year linear power output warranty. This means the panels are guaranteed to retain at least the specified percentage of their nominal 340 Wp output for a quarter of a century, which is a standard level of protection for the residential prosumer segment.
What does half-cut cell technology mean in the LEPV 120 HALF-CUT and does it actually matter?
In a half-cut design, each cell is laser-cut into two smaller halves, reducing internal resistance and lowering resistive losses during current flow. The result is better performance under partial shading conditions, such as from a chimney or nearby trees. Three bypass diodes further isolate shaded cell strings, allowing the rest of the module to continue operating at full capacity.
Do Lina Energy LEPV 120 HALF-CUT panels perform well under overcast skies?
Yes. The modules feature tempered glass with an anti-reflective coating that improves absorption of diffuse light. This is particularly relevant in climates with frequent cloud cover, where a significant portion of annual irradiation arrives as diffuse rather than direct sunlight. The panel generates power even under low-irradiance conditions, though output is proportionally lower than under full sun.
Is the LEPV 120 HALF-CUT 340 Wp module a bifacial panel?
No, the LEPV 120 HALF-CUT series is a monofacial panel. Energy is generated exclusively by the front surface of the module. Bifacial technology, which allows additional energy harvest from light reflected off the ground or rooftop surface, is not featured in this series.
Are Lina Energy LEPV 120 HALF-CUT panels compatible with standard inverters and racking systems?
Yes. The LEPV 120 HALF-CUT modules feature an IP68-rated junction box with standard MC4 connectors and typical open-circuit voltage values, ensuring compatibility with the vast majority of inverters on the market. The aluminum frame conforms to common industry dimensions, making them compatible with standard pitched and flat-roof racking systems.
