The ECO LINE N-TYPE TOPCON GLASS-GLASS BIF M108 series redefines standards of durability and efficiency in modern photovoltaic installations. Advanced N-Type TOPCon cell technology effectively minimizes light-induced degradation (LID) and guarantees above-average efficiency even in low sunlight conditions or on hot days. Thanks to the use of a unique bifacial glass-glass construction, these modules exhibit extreme resistance to external factors such as hail, heavy snow loads, or aggressive ammonia vapors, making them an ideal solution for agriculture and industrial areas. Double-sided energy generation allows for significant gains from reflected radiation, which, combined with high bifacial efficiency, radically shortens the return on investment time. These panels solve the problem of limited installation space thanks to the optimized M108 format, which combines compact dimensions with powerful output power. This model stands out from the competition with an excellent temperature coefficient and the highest fire resistance class, ensuring maximum fire safety for users. It is a product dedicated to the most demanding investors, for whom long-term yield stability and trouble-free system operation in all weather conditions are key. By choosing this solution, you can be sure that your installation is based on components with the highest mechanical durability currently available on the Polish market.

What owners get
Highest efficiency in the peer group

Efficiency up to 23.24% exceeds all listed peer comparables: JA Solar JAM60S40 LR (23%), Sunlike SKT490~510M12-108D4 (22.93%), and Trina Solar Vertex (21.2%). This is a real advantage at the same 510 Wp max power, translating into a smaller footprint for the same installed capacity.

N-type TOPCon cells instead of PERC

N-type TOPCon technology effectively limits light-induced degradation (LID) and offers a better temperature coefficient than the more common PERC cells, resulting in higher yield in high temperatures and low-irradiance conditions.

30-year product and power warranty

The manufacturer covers a full 30 years with both a product warranty and a power warranty - while most competitors (including Trina Solar or JA Solar) typically offer 12-15 years of product warranty alongside 25-30 years of power warranty. Covering the product itself for a full 30 years is uncommon in this segment.

Glass-glass construction resistant to harsh conditions

The bifacial glass-glass build offers enhanced resistance to hail, snow load, and ammonia fumes, making the series suitable for agricultural applications (e.g., installations near livestock farms) and industrial settings, where standard backsheet modules degrade faster.

Compact M108 format at high power

The M108 format delivers up to 510 Wp within relatively compact module dimensions, easing installation on limited roof areas without sacrificing per-unit power output.

Trade-offs
No Tier 1 (BNEF) status

Luxor Solar does not hold Tier 1 status per BloombergNEF classification, while comparable series such as JA Solar JAM60S40 LR and Trina Solar Vertex come from Tier 1 manufacturers. Lacking this status may limit access to bank financing on larger commercial and utility-scale projects, where lenders require modules from bankable manufacturers.

Notes from the database
  • Efficiency of 22.3% matches the TOPCon 450-500W median
  • 220.5 W/m² power density is 4.7 W/m² below TOPCon 450-500W median (225.2 W/m²) - requires larger installation area
  • Temperature coefficient of -0.29%/°C matches the TOPCon 450-500W median
  • At 27.6 kg (3.6 kg above TOPCon 450-500W median of 24.0 kg), requires checking roof load capacity
  • 77% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces

About the ECO LINE N-TYPE TOPCON GLASS-GLASS BIF M108 series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What warranty does the Luxor ECO LINE N-TYPE TOPCon Glass-Glass BIF M108 come with?
Luxor provides a 30-year product warranty and a 30-year linear power output warranty on the ECO LINE N-TYPE TOPCon Glass-Glass BIF M108 series. After 30 years the module must retain at least 89% of its rated power. This is one of the longest warranty standards available in the European market and reflects the manufacturer's confidence in the glass-glass structural durability.
Is the Luxor ECO LINE N-TYPE TOPCon BIF M108 a good fit for agricultural and agrivoltaic installations?
Yes, the ECO LINE N-TYPE TOPCon Glass-Glass BIF M108 series is specifically recommended for agrivoltaic projects. The glass-glass construction resists ammonia vapors and fertilizer exposure common on farmland. Bifacial cell architecture captures ground-reflected irradiance from soil or vegetation, increasing energy yield without additional footprint. High mechanical load ratings (up to 5400 Pa snow load) and hail resistance add further reliability under variable Central European weather conditions.
What is the peak power of the Luxor ECO LINE N-TYPE TOPCon Glass-Glass BIF M108 and what does it mean in practice?
The module's peak power is 510 Wp under STC conditions. In practical terms, a 10 kWp system requires only 20 panels instead of 25 with older 400 W modules. The M108 format (108 half-cut cells) combines compact dimensions with high output power, reducing the number of mounting brackets needed and simplifying DC string wiring.
How does TOPCon technology in the Luxor ECO LINE BIF M108 series differ from standard PERC panels?
N-Type TOPCon cells feature an ultra-thin tunnel oxide passivation layer on the rear side that significantly reduces carrier recombination. This results in higher module efficiency and a better temperature coefficient (approximately -0.25%/°C vs. -0.35%/°C for PERC). N-type doping also makes the cells virtually immune to light-induced degradation (LID), delivering more stable energy output over the full system lifetime.
Does the Luxor ECO LINE N-TYPE TOPCon Glass-Glass BIF M108 perform well on cloudy days and during heat waves?
Yes. N-Type TOPCon technology delivers superior low-light performance compared to PERC, which is particularly valuable under the often overcast conditions in Central Europe. The low temperature coefficient (-0.25%/°C) means the module loses less power on hot days - for example at a cell temperature of 45°C power loss is noticeably smaller than with PERC equivalents. An anti-reflective front glass coating further improves diffuse irradiance absorption.
Does the bifacial design of the Luxor ECO LINE N-TYPE TOPCon BIF M108 actually increase energy production, and under what conditions?
Bifacial energy generation provides measurable gains primarily in ground-mounted systems and on rooftops with high-albedo surfaces such as white TPO membranes, where the albedo factor reaches 0.3-0.6. On typical grass-covered ground, annual production gains of 5-15% over a monofacial equivalent can be expected. On darker substrates the bifacial gain is smaller, but the glass-glass construction still improves mechanical durability and resistance to potential-induced degradation (PID).
