Strong in heat, no clear weak spot
The Exiom EX585-605TC(B)-144(HC)(182)BF photovoltaic module series is an advanced solution based on N-type TOPCon cell technology, which redefines performance standards in challenging lighting conditions. Thanks to the bifacial design, these panels allow for additional energy yield from reflected radiation, making them an ideal choice for investors building large-scale agrivoltaic farms and demanding commercial installations. The use of 144 Half-Cut cells in the 182 mm format effectively minimizes resistive losses and limits the risk of hotspots, directly translating into a longer lifespan for the entire system. This solution eliminates the problem of rapid power degradation, offering significantly better parameter stability over time than traditional P-type modules. By choosing this series, the user receives a product with an exceptionally low temperature coefficient, which guarantees high electricity production even on hot summer days. They are distinguished from the competition by precise European quality control and maximization of yields from limited ground or roof areas. This equipment is designed for those seeking uncompromising efficiency and high resistance to LID and LeTID degradation, ensuring a fast return on investment in the Polish climate. This model perfectly solves the problem of limited space, generating more energy from every square meter of the installation.
Ranking
Signals from the data
Utility-scale, commercial, agrivoltaic, shaded-installations and hot-climate.
Top 4% of the TOPCon 550-600 W segment, against a median of -0.290. Ranked 1,309th in the whole database.
A peak efficiency of 23.4% places the series at the level of the closest peer comparable — GCL SIROT NT10/72GDF (23.42%) — and exceeds the JS Solar JS210MHC120 (21.4%) and LEDVANCE M585~605P60UB (21.37%) by more than 2 percentage points. A 2 pp efficiency advantage translates to approximately 10% more energy yield from the same roof or ground area.
N-type cells exhibit significantly lower light-induced degradation (LID) and light- and elevated-temperature-induced degradation (LeTID) than legacy P-type PERC cells, resulting in a slower power decline during the first 2–5 years of operation. Over a 30-year system lifetime, the cumulative energy yield is measurably higher than that of PERC modules with nominally similar rated power.
The bifacial construction captures irradiance reflected from the ground surface — the albedo coefficient is approximately 20% for concrete, 35%+ for light-colored gravel, and up to 80% for snow. For ground-mounted and agrivoltaic installations, this translates to a real increase in annual energy yield of 5–30% compared to a monofacial equivalent.
The manufacturer offers a 30-year linear performance warranty — five years longer than the 25-year benchmark applied by JS Solar JS210MHC120 and LEDVANCE in the same power class. The extended warranty horizon directly reduces investment risk in utility-scale projects with long financing cycles and improves their bankability, even in the absence of BNEF Tier 1 status.
Exiom has commissioned a 500 MW module factory in Langreo (Asturias) in partnership with Iberdrola, facilitating compliance with EU regulatory requirements on local content (eligibility for IPCEI and NZIA fund subsidies). The European supply chain shortens lead times and reduces exposure to import tariff risk.
Exiom Solution does not appear on the BloombergNEF list of bankable manufacturers (tier_1_bankable: false), which may represent a formal barrier when securing project financing from lenders that require a BNEF-certified supplier. For utility-scale PV projects above 1 MWp financed through investment loans, the financing institution's acceptance of the manufacturer should be verified early in the development process.
- Efficiency of 22.6% matches the TOPCon 550-600W median
- At 226.4 W/m² power density, roof space requirements are typical for TOPCon 550-600W panels
- At -0.28%/°C, hot weather performance is typical for TOPCon 550-600W panels
- 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces
- In the top 26% for efficiency among all TOPCon panels
