Photovoltaic panels from the Lina Energy LEPV 120 Nexa TOPCon series are an advanced solution based on N-type cells, which set a new standard of efficiency in residential and commercial installations. The use of innovative TOPCon technology allows for a significant reduction in energy losses and minimization of light-induced degradation. As a result, users gain higher efficiency in low-light conditions, which is crucial in the Polish climate, especially on cloudy days or during autumn-winter periods. This series effectively solves the problem of power drop at high temperatures, offering an excellent temperature coefficient, which translates into stable system operation throughout the year. LEPV 120 Nexa modules are characterized by exceptional mechanical durability and an aesthetic finish, making them an ideal choice for demanding investors who care about the appearance of their roof. They stand out from the competition through a precise combination of dense cell packing and optimal current flow management, which minimizes the risk of micro-cracks. It is an investment that ensures maximum energy yield from a smaller area, dedicated to those seeking uncompromising quality and longevity for their solar power plant.

What owners get
N-type TOPCon cells

TOPCon technology reduces LID degradation and improves low-light and high-temperature performance compared to older PERC cells, translating into higher real-world annual energy yield in Poland's climate.

Bifacial design

The module generates additional energy from its rear side, so mounting over a light-colored or reflective surface (e.g., a white roof or gravel) delivers a real yield boost beyond the rated nameplate power.

30-year power warranty

The linear power warranty extends to 30 years (with a 25-year product warranty), exceeding the segment's typical 25/25-year standard and implying a longer period of guaranteed stable energy output.

Efficiency near segment leaders

Efficiency of 21.95-22.18% places the series close to segment leaders (Sunket at 22.24%, Shinson at 22.24%) and well above thin-film modules such as First Solar's Series 6 Plus Bifacial (19%).

High power density

Up to 480 Wp from a 120-cell module means more energy from less roof area, reducing the number of panels needed in installations with limited mounting space.

Trade-offs
Series discontinued

The LEPV 120 Nexa TOPCon series has been discontinued, meaning limited availability of spare parts and potential difficulties with future service and warranty claim fulfillment.

Long-warranty enforcement risk

Lina Energy has only been active since 2017, and production of this specific series has ended - given the stated 30-year power warranty, this raises questions about the manufacturer's ability to support service claims over such a long horizon.

Notes from the database
  • Efficiency of 22.2% matches the TOPCon 450-500W median
  • Power density of 221.7 W/m² is 3.5 W/m² below TOPCon 450-500W median (225.2 W/m²) - needs more roof space
  • -0.36%/°C temperature coefficient - 0.07pp worse than TOPCon 450-500W median (-0.29%/°C), expect higher hot weather losses
  • Weight of 25.9 kg is 1.9 kg above TOPCon 450-500W median (24.0 kg) - verify structural support
  • Bifaciality factor of 10% can add 0-2% extra yield with reflective mounting surface

Common questions

6 answered
What does the bifacial design of the Lina Energy LEPV 120 Nexa TOPCon panels mean, and is it worth it?
A bifacial panel generates power from both sides — the rear surface captures light reflected off the roof, snow, or ground. Bifacial gain typically ranges from 5–15% depending on surface albedo and mounting clearance. The benefit is greatest on light-colored or reflective surfaces with adequate air gap below the panel. On dark roofing material the rear gain is minimal, but the N-type TOPCon cells still deliver superior low-light performance regardless of bifacial contribution.
What are the warranties on the Lina Energy LEPV 120 Nexa TOPCon panels?
Lina Energy provides a 25-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty guaranteeing at least 84.5% of the 480 Wp nameplate rating after 30 years. The 30-year power warranty exceeds the industry-standard 25-year term and reflects the manufacturer's confidence in long-term TOPCon cell stability.
How do the LEPV 120 Nexa TOPCon panels perform in high summer temperatures?
The temperature coefficient of Pmax is -0.36%/°C, which is competitive for a premium-class module. At a typical module surface temperature of around 70°C on a hot sunny day, power loss is noticeably lower than with older PERC modules. This translates directly into higher annual energy yield from the system, especially during peak summer months.
Is TOPCon technology in the LEPV 120 Nexa series genuinely better than standard PERC?
Yes. N-type TOPCon cells offer higher baseline efficiency and significantly lower LID (Light-Induced Degradation) compared to P-type PERC cells. In practice this means better low-light performance — critical in Central European climates — and a slower power degradation curve across the full 30-year warranty period. TOPCon also achieves a higher bifacial factor, maximizing rear-side energy harvest.
How many cells does the Lina Energy LEPV 120 Nexa TOPCon panel have, and what does that mean in practice?
The module uses 120 half-cut N-type TOPCon cells, delivering up to 480 Wp at approximately 22% module efficiency. The half-cut cell design halves the current per cell, reducing resistive losses and improving shade tolerance — a practical advantage on roofs where chimneys, dormers, or adjacent structures may cast partial shade on the array.
Is the Lina Energy LEPV 120 Nexa TOPCon series still available for purchase?
The LEPV 120 Nexa TOPCon series has been discontinued and is no longer in active production. Limited stock may still be available through distributors with existing inventory — availability should be confirmed directly with your supplier before ordering. For new installations, Lina Energy's current lineup includes newer series built on the same proven N-type TOPCon cell technology.
