The bifacial design captures additional rear-side irradiance reflected from the ground, a meaningful advantage on elevated or flat-roof mounts. - **Up to 22.26% efficiency — near segment top** - Efficiency of 21.49-22.26% at up to 435 Wp places the series close to the top of comparable peers (SunLink SL5N108 at 22.3%, SunKean SKT415~435M10-108D4 at 22.27%), clearly above Just Solar's IBC Mono Module (22.1%). The gap to the segment leader is only 0.04 pp, negligible in practical yield terms. - **Extended 25/30-year warranty** - A 25-year product warranty and 30-year power warranty exceed the market standard of most older PERC modules (typically 12/25 years), reducing investor risk over the system's long-term operation. - **Compact 108-cell format, low weight** - Dimensions of 1724x1134x30 mm and a weight of 23.4 kg make the panel easy to transport and install on pitched residential roofs with limited surface area, without requiring reinforced roof structures. ## Cons - **Limited manufacturer track record** - Lina Energy (UK) has been operating since 2017, roughly 9 years — shorter than many established Tier-1 manufacturers in the comparable segment. Given the 30-year power warranty, a shorter operating history increases uncertainty around the manufacturer's servicing capability over the full warranty period. - **30-year power retention below best-in-class** - Available technical documentation indicates guaranteed power retention of approximately 84.5% after 30 years, below the best premium N-type TOPCon modules in the segment, which reach as high as ~87-88%. The gap is small but measurable against top-tier competitors. ## About this series The Lina Energy LEPV 108 Nexa TOPCon panel series is a technologically advanced solution based on **N-type silicon cells**, which set new efficiency standards in the Polish climate. The use of innovative TOPCon architecture allows for significantly higher efficiency than traditional modules, which directly translates into maximizing yields from every square meter of the roof. This series effectively eliminates the problem of rapid component aging, offering **minimal light-induced degradation**, which ensures the installation maintains its power for decades. The optimal configuration of 108 cells makes the panels extremely handy and ideal for installation on residential buildings where space is often limited. A key competitive advantage is the **exceptional performance at low irradiance**, allowing for efficient electricity production even on cloudy days or during morning and evening hours. This is complemented by a **very low temperature coefficient**, guaranteeing stable system operation during summer heatwaves. This is a product aimed at demanding investors who expect a combination of the latest innovations with an aesthetic appearance and the **energy security** of their household or business. ## Notable figures - At 22.0% efficiency, this panel is on par with typical \*\*TOPCon 400-450W\*\* modules - Power density of 219.9 W/m² matches the \*\*TOPCon 400-450W\*\* median - -0.36%/°C temperature coefficient - 0.07pp worse than \*\*TOPCon 400-450W\*\* median (-0.29%/°C), expect higher hot weather losses - Weight of 23.4 kg is 1.4 kg above \*\*TOPCon 400-450W\*\* median (22.0 kg) - verify structural support - Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof ## Questions ### What efficiency do Lina Energy LEPV 108 Nexa TOPCon panels achieve and what drives it? The LEPV 108 Nexa TOPCon series reaches module efficiency of up to 22.26%, placing it at the top of the residential solar market. This is driven by N-type TOPCon cells, which feature a significantly lower carrier recombination rate compared to conventional PERC technology. In practice, this means more energy output from the same roof area without requiring additional space. ### What warranties does the Lina Energy LEPV 108 Nexa TOPCon series carry? Lina Energy provides a 25-year product warranty covering materials and workmanship, along with a 30-year linear power warranty guaranteeing that output will not fall below 84.5% of nominal power at the end of the warranty period. This is among the longest power output guarantees available for monocrystalline modules and reflects the proven durability of TOPCon cell technology. ### Are the LEPV 108 Nexa TOPCon panels bifacial, and what does that mean for my system? Yes, the LEPV 108 Nexa TOPCon series uses bifacial technology, meaning the rear side of the module also generates electricity from reflected irradiance. Over light-colored surfaces or white roofing membranes, the bifacial gain can add several percentage points to annual energy yield at no extra cost. On a standard dark pitched roof the benefit is smaller but still measurable and requires no additional components. ### How do Lina Energy LEPV 108 Nexa TOPCon panels perform in overcast or low-light conditions? The LEPV 108 Nexa TOPCon series is specifically well-suited for temperate climates with frequent cloud cover. N-type TOPCon cells deliver excellent low-irradiance performance, generating electricity efficiently on overcast days and during early morning and late afternoon hours. Compared to older PERC modules, TOPCon technology handles diffuse, scattered light more effectively, which is a meaningful advantage across all four seasons. ### Is the 435 Wp Lina Energy LEPV 108 Nexa TOPCon panel suitable for a standard residential rooftop? Yes, the 108 half-cut cell configuration results in compact dimensions of 1724 × 1134 × 30 mm and a weight of approximately 23.4 kg, which is compact for a 435 Wp module. This makes the panel straightforward to transport and install on typical pitched or gabled rooftops using standard aluminum racking. Installers can handle these modules without specialized lifting equipment. ### What does the -0.36 %/°C temperature coefficient of the LEPV 108 Nexa TOPCon mean during hot summer days? A temperature coefficient of Pmax at -0.36 %/°C is among the lowest in this product class. It means that for every degree Celsius the module temperature rises above 25°C, power output drops by only 0.36%. Older PERC cells typically show -0.38 % to -0.40 %/°C. On a hot summer day when a roof surface heats to 60-70°C, this difference results in a measurably higher energy yield from the entire system. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/7-bcf646b95023.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A480-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a480-mah54mw) | 480 W | +50 W, cooler, +2.1 pp | | [Gokin GK-5-54HG-480M](https://comparepv.com/panel/gokin-gk-5-54hg-480m) | 480 W | +50 W, cooler, +2.1 pp | | [Jinko Solar JKM480N-48QL6-DB-F2-EU](https://comparepv.com/panel/jinko-solar-jkm480n-48ql6-db-f2-eu) | 480 W | +50 W, cooler, +2.0 pp | | [Gamko New Energy GKA96N-PRO-480W](https://comparepv.com/panel/gamko-new-energy-gka96n-pro-480w) | 480 W | +50 W, cooler, +2.0 pp | | [Lina Energy MEPV 350 (Terracotta)](https://comparepv.com/panel/lina-energy-mepv-350-terracotta) | 350 W | -80 W, lighter, -4.1 pp | | [Lina Energy MEPV 360 (Terracotta)](https://comparepv.com/panel/lina-energy-mepv-360-terracotta) | 360 W | -70 W, lighter, -3.6 pp | | [Lina Energy LEPV 410](https://comparepv.com/panel/lina-energy-lepv-410) | 410 W | -20 W, lighter, -1.0 pp | | [Lina Energy LEPV 415](https://comparepv.com/panel/lina-energy-lepv-415) | 415 W | -15 W, lighter, -0.8 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +80 W, cooler, +3.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +65 W, cooler, +2.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +75 W, cooler, +2.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +60 W, cooler, +2.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +70 W, cooler, +2.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +70 W, cooler, +2.5 pp | --- Source: https://comparepv.com/panel/lina-energy-lepv-430 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.
