The Lina Energy LEPV 144 BIFACIAL series is designed to maximize energy yield in situations where every square meter counts, and where reflected light from the ground can significantly increase production. A key advantage is the bifacial design, which allows for the utilization of radiation from both sides - making the installation particularly effective on roofs with light-reflecting membranes, on ground-mounted structures, carports, or pergolas.

These are monocrystalline modules with 144 cells, optimized for stable operation under variable conditions and predictable energy yields over the long term. In practice, this means a lower risk of underestimating production in commercial projects, as well as greater investment profitability with limited mounting space.

Another distinguishing feature is the high degree of sealing (IP68 class), which makes the installation easier in challenging environmental conditions, as well as the long warranty, which supports the financial security of the project. The LEPV 144 BIFACIAL series is ideal for installers and investors looking for modules for PV farms, industrial facilities, and modern, high-end prosumer projects.

What owners get
Bifacial design boosts energy yield

Double-sided cells capture light reflected from the ground, meaningfully increasing output on light-colored membrane roofs, ground-mount arrays, carports, and pergolas - an advantage standard monofacial modules in this power class (550 Wp) don't offer.

30-year product and power warranty

The manufacturer offers 30 years of coverage on both the product and power output, exceeding the market-standard 12/25-year terms common in this segment, which strengthens the financial security of long-term investments, particularly for utility-scale PV projects.

High IP68 junction box rating

The IP68 rating on electrical components provides resistance to moisture and dust, easing installation on solar farms, industrial buildings, and other sites exposed to demanding environmental conditions.

Efficiency matches segment PERC leaders

The 21.28% efficiency matches the best comparable 550 Wp PERC-based models, such as IBC Solar's 182M Half Cell (21.28%), Goldi Solar's GS10-B144-TF (21.3%), and Jetion's JT SGh (21.3%), placing the series at the top of its technology class.

Low power temperature coefficient

A Pmax temperature coefficient of -0.34%/°C limits power loss at high operating temperatures, translating to more stable output in summer months and warmer climates compared to typical PERC modules (around -0.35 to -0.38%/°C).

Trade-offs
PERC cells instead of newer N-type tech

The module relies on older P-type PERC technology, while the premium segment is increasingly shifting to N-type TOPCon/HJT cells offering lower LID degradation and efficiencies in the 22-23% range. This may limit the series' technological edge over the coming years.

No confirmed BNEF Tier 1 status

Current publicly available BNEF Tier 1 lists show no clear confirmation of Lina Energy, and combined with the manufacturer's relatively young age (founded in 2017), this may raise bankability questions for large commercial financing compared to established players among the peer comparables.

Common questions

6 answered
What warranty comes with the Lina Energy LEPV 144 BIFACIAL panels?
The LEPV 144 BIFACIAL series comes with a 30-year product warranty and a 30-year power warranty, placing it among the best-warranted modules on the market. The power warranty guarantees at least 80% of the rated output over the entire period. For investors, this means solid financial protection for three decades without the need to replace the modules.
What does bifacial technology mean in the LEPV 144 series and when does it pay off?
The bifacial design allows LEPV 144 BIFACIAL modules to absorb solar irradiance from both the front and rear surfaces. Rear-side gain from ground albedo typically adds 5–15% to overall energy yield, depending on the surface reflectivity. The greatest benefit is seen on installations with light-colored roofing membranes, ground-mount systems, carports, and pergolas where reflected light is highest.
What is the peak power and efficiency of the LEPV 144 BIFACIAL modules?
The LEPV 144 BIFACIAL series delivers a peak power of 550 Wp at a module efficiency of 21.28%. The monocrystalline PERC half-cut cell layout with 144 cells provides high power density within a 2279×1134×35 mm frame weighing 33 kg. These figures suit both utility-scale PV farms and premium prosumer installations where roof space is limited.
Are Lina Energy LEPV 144 BIFACIAL panels a good fit for commercial rooftops with white membranes?
Yes, flat commercial rooftops with white TPO or PVC membranes are one of the best use cases for this series. Light-colored membranes reflect a significant share of irradiance toward the module's rear glass, measurably increasing energy production. The IP68-rated junction box also protects against moisture and debris commonly found on flat industrial roofs.
How does the LEPV 144 BIFACIAL perform in high summer temperatures?
The temperature coefficient of Pmax for the LEPV 144 BIFACIAL is –0.34%/°C, meaning relatively modest power losses when cell temperature exceeds 25°C STC. Compared to older-generation modules with coefficients around –0.40 to –0.45%/°C, this series retains more output during peak summer hours, improving overall annual energy yield in hot climates.
Is the Lina Energy LEPV 144 BIFACIAL series still available for purchase?
Yes, the LEPV 144 BIFACIAL series is currently in active production and available to order. Modules are distributed across Poland and Europe through authorized Lina Energy partners. For current stock levels or lead times, contact an authorized distributor directly.
