Solid all-round for its segment
The AE Solar ECLIPSE N-TYPE BACK CONTACT TECHNOLOGY series is a breakthrough in photovoltaic module architecture that eliminates traditional cell shading by busbars. By moving all electrical contacts to the rear side of the module, these panels offer maximum light absorption surface, which directly translates to higher efficiency even in less favorable weather conditions. The use of N-type cells guarantees minimal light-induced degradation and excellent power stability over a long-term horizon, which is key for a fast return on investment. This is an ideal solution for investors seeking the highest efficiency per square meter of roof, especially where available mounting space is strictly limited. Advanced Back Contact technology effectively eliminates the problem of energy losses caused by the front grid, while offering exceptional Full Black aesthetics that blend perfectly with modern building architecture. What distinguishes them from competitors' solutions is not only their elegant, uniform appearance, but above all increased resistance to high temperatures, which allows for stable and high electricity production on hot days. By choosing this series, the user receives a premium class product that combines technological innovation with uncompromising reliability, making it the optimal choice for the most demanding residential installations and commercial systems.
Ranking
Signals from the data
Residential, commercial and hot-climate.
The module's efficiency is 23-24%, exceeding direct competitors such as Renesola RS4-470~490NX-E1 (22.71%) and Horay Solar HS 182-120 TC (22.6%). The only comparable panel in the comparison is Solar-Fabrik Mono S4 Halfcut BC White (24%), which places the ECLIPSE series among the top performers in the 470-490 Wp segment.
The temperature coefficient confirmed by the manufacturer, -0.26%/°C, is lower than the typical value for N-type TOPCon (-0.30%/°C) and significantly better than older PERC (-0.35%/°C). This translates to measurably higher power generation on hot days, which is particularly important for rooftop installations with poor ventilation.
The manufacturer declares an initial degradation rate of 1% and a linear rate of 0.35%/year, which, after 30 years, results in maintaining 88.8% of the nominal power. Standard TOPCon/PERC modules typically have a degradation rate of 0.40-0.45%/year and a 25-year warranty at a level of 84.8-86%. The 30-year product and power warranty confirms the credibility of this declaration.
Transferring all electrical connections to the rear side eliminates the front-facing ribs, which, according to the manufacturer's data, reduces power losses under shading by more than 70% compared to traditional designs. Furthermore, the BC technology significantly reduces the risk of hotspot formation, which extends the lifespan of the module.
The bifacial design with double glass provides additional power generation from reflected radiation from the ground (typically 5-15% depending on albedo). AE Solar has a Tier-1 bankable status (BNEF), the company has been operating since 2003 with headquarters in Germany, which significantly reduces contractual and service-related risks in the context of a 30-year warranty.
Modules with Back Contact (IBC/BC) technology have historically cost approximately 15-20% more than comparable N-type TOPCon modules in the same power class. For a typical 10 kWp installation (approximately 20 modules), the difference compared to standard N-type is estimated to be 1,500-2,500 PLN. The premium is only justified in installations with limited roof space, where the higher efficiency directly translates into increased overall system power.
- At 23.5% efficiency, this panel is on par with typical Back Contact 450-500W modules
- At 235.2 W/m² power density, roof space requirements are typical for Back Contact 450-500W panels
- Temperature coefficient of -0.26%/°C matches the Back Contact 450-500W median
- Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof
- Ranked #749 out of 14129 panels for efficiency in the database
