This means less roof area is needed to reach the same installed capacity. - **N-type IBC (Back Contact) cells** - The absence of front-side metallization grid and busbars eliminates shading losses from contacts and delivers a uniform total-black look without compromising electrical performance. - **30-year linear power warranty** - A 30-year power warranty and 20-year product warranty exceed the typical market standard (10-15 years product, 25 years linear for many competitors), simplifying long-term ROI planning. - **Half-Cut design reduces microcracking** - Splitting cells into halves lowers mechanical stress and the risk of microcrack propagation, and under partial shading (leaves, chimneys) power losses are lower than with full-size cells. - **Low temperature coefficient of -0.29%/°C** - According to ENF Solar datasheet data, the Pmax temperature coefficient is -0.29%/°C, better than the typical -0.35 to -0.40%/°C for PERC cells — the module loses less power at high roof temperatures in summer. ## Cons - **No bifacial variant available** - The series does not offer bifacial modules, so in ground-mount installations or on high-albedo surfaces it forfeits the several-to-teens-percent additional yield achievable with competing bifacial modules of the same power class. - **Manufacturer not on the BNEF Tier 1 list** - Lina Energy (United Kingdom, founded 2017) does not appear on BloombergNEF's Tier 1 bankability list, and its relatively short track record (~9 years) may complicate financing for larger commercial projects and raise questions about honoring the 30-year linear power warranty. ## About this series The Lina Energy LEPV 120 ULTRA PREMIUM series is designed for maximum aesthetics and stable operation in real-world conditions - these are total black modules that complement modern architecture and do not detract from the appearance of the roof. The use of **N-type cells** and **IBC (back contact) technology** allows for minimizing losses due to shading and better utilization of the active surface, which translates into improved system performance. Additionally, the **Half-Cut** design enhances resistance to micro-cracks and reduces the risk of yield losses over time, particularly in systems exposed to temperature and load fluctuations. This is a good choice for investors who expect long-term predictable energy production - whether in single-family homes, small businesses, or premium projects where appearance, durability, and parameter certainty are important. The series is also distinguished by **extended linear warranty**, making it easier to plan returns on investment and limit long-term risk costs. ## Notable figures - Efficiency of 22.3% matches the \*\*Back Contact 400-450W\*\* median - At 222.9 W/m² power density, roof space requirements are typical for \*\*Back Contact 400-450W\*\* panels - At -0.29%/°C, hot weather performance is typical for \*\*Back Contact 400-450W\*\* panels - #5082 for efficiency, #2165 for temperature performance out of 14005 panels ## Questions ### What warranty comes with the Lina Energy LEPV 120 ULTRA PREMIUM panels? The LEPV 120 ULTRA PREMIUM series carries a 20-year product warranty covering manufacturing defects and material faults, along with a 30-year linear power output warranty. The linear guarantee ensures a predictable, gradual power degradation curve over three decades, making it easier to model return on investment and reduce financial risk over the system's lifetime. ### What is IBC (Back Contact) technology in the LEPV 120 ULTRA PREMIUM series and what does it mean for real-world performance? IBC (Interdigitated Back Contact) moves all electrical contacts to the rear side of the cell, leaving the front surface entirely unobstructed for light absorption. This eliminates shading losses from front-side busbars, increases cell efficiency, and improves low-light and partial-shading performance. Combined with N-type cell architecture, IBC delivers higher energy yield per square meter compared to standard PERC or TOPCon modules. ### Do the LEPV 120 ULTRA PREMIUM all-black panels work well on a modern house with a dark roof? Yes, the LEPV 120 ULTRA PREMIUM is a total black module — cells, frame, and backsheet share a uniform black finish. This aesthetic integrates seamlessly with anthracite or black ceramic roof tiles and standing-seam metal roofing. It is a popular choice for premium residential projects where the visual impact of the solar installation is a key consideration for the homeowner. ### How many Lina Energy LEPV 120 ULTRA PREMIUM panels do I need for a 5 kWp system? At a rated output of 400 Wp per module, you need 13 panels to reach approximately 5.2 kWp. The exact number depends on roof area, orientation, shading, and inverter configuration, so it is worth consulting a certified installer for a site-specific design. A 13-panel array at this power class typically requires around 20–22 m² of unobstructed roof surface. ### How does the half-cut cell layout in the LEPV 120 ULTRA PREMIUM reduce losses when a chimney or antenna partially shades the array? Half-cut cells split each cell into two independent halves, lowering resistive losses and allowing each half of the panel to operate separately under partial shading. When a chimney or satellite dish shades one section, only that portion loses output while the rest of the module continues producing at full capacity. Paired with the IBC back-contact architecture and N-type cells, this significantly limits energy yield losses in real-world rooftop installations. ### Is the Lina Energy LEPV 120 ULTRA PREMIUM a good fit for a small business or warehouse with high daytime energy consumption? Yes, the LEPV 120 ULTRA PREMIUM suits both residential and small commercial applications with significant daytime loads. The 400 Wp rated output delivers high installed capacity on a limited roof footprint, while the 30-year linear power warranty and N-type cell technology ensure low LCOE and stable generation across the full system lifetime — key factors when sizing a system to offset commercial electricity bills. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/5-003036f32174.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Luxor Solar LX-440M/182-108+GG](https://comparepv.com/panel/luxor-solar-lx-440m-182-108-gg) | 440 W | +40 W, cooler, +0.8 pp | | [Just Solar JST-EDMH-(445-465)W-TD (450W class)](https://comparepv.com/panel/just-solar-jst-edmh-445-465-w-td-450w-class) | 450 W | +50 W, hotter, +0.7 pp | | [Q-SUN Solar QNN182-HG450-54](https://comparepv.com/panel/qn-solar-pv-limited-qnn182-hg450-54) | 450 W | +50 W, heavier, +0.7 pp | | [Huayao HY440-N108BDD](https://comparepv.com/panel/huayao-hy440-n108bdd) | 450 W | +50 W, heavier, +0.7 pp | | [BYD NLBK-27-450](https://comparepv.com/panel/byd-nlbk-27-450) | 450 W | +50 W, heavier, +0.7 pp | | [Renesola RS41-450NBG-E3](https://comparepv.com/panel/renesola-rs41-450nbg-e3) | 450 W | +50 W, heavier, +0.7 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +110 W, cooler, +2.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +95 W, cooler, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +105 W, cooler, +2.4 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +90 W, cooler, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +100 W, cooler, +2.2 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +100 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/lina-energy-lepv-400 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
