Efficiency leader, no clear weak spot
The ECO LINE TOPCON GLASS-GLASS BIFACIAL series is a response to the growing requirements for durability and energy yields, combining the advantages of bifacial power generation with an innovative N-type cell structure. The use of TOPCon technology allows for minimizing losses associated with charge recombination, which directly translates into higher module efficiency even under limited sunlight. The construction based on two layers of tempered glass provides exceptional mechanical resistance and full protection against aggressive environmental factors such as ammonia or salt mist. This makes these panels an optimal choice for installations on livestock buildings, coastal areas, and large ground-mounted farms. This solution eliminates the problem of light- and temperature-induced degradation, offering parameter stability for decades. A key advantage over the competition is increased bifacial efficiency, which, combined with a low annual degradation rate, guarantees investors the highest power density from the available area. By choosing this series, the user receives a product designed to maximize self-consumption and shorten the payback period thanks to stable power production in all weather conditions.
Ranking
Signals from the data
Commercial.
Top 4% of the TOPCon 450-500 W segment, against a median of 22.52%. Ranked 627th in the whole database.
Top 10% of the TOPCon 450-500 W segment, against a median of 225.2.
The manufacturer offers a 30-year product warranty alongside a 30-year linear power warranty – uncommon in this segment, where competitors (e.g., Jinko, Vikram) typically provide 25 years on the product with 30 years on power. This extended coverage meaningfully lengthens the safe investment horizon.
The 22.6-23.6% range clearly outperforms Jinko Solar JS182MHC120 (21.48%) and Vikram Solar SOMERA (21.51%) at the same maximum power of 465 Wp – translating into higher energy yield from the same roof or ground footprint.
Two layers of tempered glass provide resistance to ammonia and salt mist, making the series suitable for livestock buildings and coastal installations – applications where standard backsheet modules degrade faster.
N-type TOPCon cells reduce recombination losses and maintain higher efficiency under low irradiance, while bifacial power generation further increases energy yield per unit of area compared to monofacial modules.
Luxor Solar has operated since 2007 and is headquartered in Germany, giving it a long manufacturing and after-sales support history in Europe – the ECO LINE series is not discontinued (launched 2023, still current in 2026).
Luxor Solar does not appear on the BloombergNEF Tier 1 bankable manufacturers list (Q1/Q2 2026), unlike companies such as Jinko Solar or Trina Solar. This can complicate financing for large-scale projects where commercial banks require Tier 1 supplier collateral.
The maximum efficiency of 23.6% is lower than Just Solar's JST-EDMH-(445-465)W-TD (23.81%) at the same 465 Wp maximum power – a small relative gap (about 0.9 pp), but on large ground-mount projects it can translate into slightly lower power density per hectare.
- Efficiency of 23.6% is 1.1pp above the TOPCon 450-500W median (22.5%)
- 232.7 W/m² power density - 7.5 W/m² more than TOPCon 450-500W median (225.2 W/m²), more power per roof area
- Temperature coefficient of -0.29%/°C matches the TOPCon 450-500W median
- Bifacial design (77% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof
- #627 for efficiency, #2165 for temperature performance out of 14005 panels
