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. ## About this series 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. ## Notable figures - At 21.3% efficiency, this panel is on par with typical \*\*PERC 550-600W\*\* modules - Power density of 212.8 W/m² matches the \*\*PERC 550-600W\*\* median - At -0.34%/°C, hot weather performance is typical for \*\*PERC 550-600W\*\* panels - Weight of 33.0 kg is 2.2 kg above \*\*PERC 550-600W\*\* median (30.8 kg) - verify structural support - In the top 63% for efficiency among all PERC panels ## Questions ### 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. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/10-74c9d8270124.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +3.7 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +3.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.3 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, lighter, +3.2 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +90 W, cooler, +3.5 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +85 W, cooler, +3.3 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +80 W, cooler, +3.1 pp | --- Source: https://comparepv.com/panel/lina-energy-lepv-550 Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
