A 2 pp efficiency advantage translates to approximately 10% more energy yield from the same roof or ground area. - **N-type TOPCon: low LID and LeTID degradation** - 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. - **Bifacial design: +5–30% gain from albedo** - 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. - **30-year linear power warranty** - 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. - **European manufacturing (Asturias, Spain)** - 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. ## Cons - **No BNEF Tier 1 status** - 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. ## About this series 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. ## Notable figures - Efficiency of 23.4% is 0.6pp above the \*\*TOPCon 600-650W\*\* median (22.8%) - 234.1 W/m² power density - 6.4 W/m² more than \*\*TOPCon 600-650W\*\* median (227.7 W/m²), more power per roof area - Temperature coefficient of -0.28%/°C matches the \*\*TOPCon 600-650W\*\* median - 31.5 kg weight - 1.2 kg lighter than \*\*TOPCon 600-650W\*\* median (32.7 kg), reducing installation effort - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## Questions ### How does the N-TOPCon technology used in the Exiom EX585-605TC series differ from older PERC modules? N-TOPCon cells feature an additional tunnel oxide layer that drastically reduces charge carrier recombination. In practice, this translates to efficiencies of up to 23.4% (model EX605), significantly higher than those of typical PERC modules. Equally important, n-type technology eliminates LID and LeTID degradation, meaning the module does not exhibit a noticeable power drop relative to its nameplate rating after the first months of operation. ### What warranty is offered on the Exiom EX585-605TC(B)-144(HC)(182)BF panels, and what does it cover? The manufacturer provides a 25-year product warranty covering defects in materials and workmanship. In addition, a separate 30-year linear power warranty guarantees minimum output performance over three decades of operation. This is one of the most comprehensive warranty packages available in the commercial-grade module segment and a compelling factor when calculating project payback period. ### How much more energy does the bifacial Exiom EX585-605TC module generate compared to a standard monofacial module? The rear side of a bifacial module captures irradiance reflected from the ground, rooftop surface, or surrounding terrain. With a typical ground albedo (light soil, gravel, or snow), the additional energy yield ranges from 5% to 25%. The rated power of 585–605 Wp refers exclusively to the front-side performance. The highest bifacial gains are achieved in ground-mounted systems with high-albedo surfaces or on white roofing membranes. ### Is the Exiom EX585-605TC(B) series suitable for agrivoltaic farm installations? Yes, this series was designed with such applications in mind. The large 182 mm cell format and power output of up to 605 Wp allow large areas to be covered with fewer modules, reducing balance-of-system (BoS) and racking costs. Bifaciality is particularly advantageous in agrivoltaic systems, as modules mounted at an appropriate height allow partial light transmission to crops while simultaneously harvesting irradiance reflected from the soil or vegetation below. ### Do Exiom EX585-605TC panels suffer significant power loss during hot summer days? N-TOPCon technology exhibits a lower temperature coefficient than PERC cells, typically around -0.29%/°C. This means that at a cell temperature of approximately 65°C (peak summer conditions), the power loss is roughly 10–11%, compared to 13–14% for older module technologies. In a Central European climate, this difference results in measurably higher annual energy yield, particularly during June and July. ### Where are Exiom panels manufactured, and can they be trusted for a large commercial installation? Exiom Solution S.A. is a manufacturer headquartered in Spain, with a TOPCon module factory being built in partnership with Iberdrola targeting a production capacity of 500 MW per year. The company applies European quality control standards, and its products have been deployed in installations across more than 50 countries, with a cumulative installed capacity exceeding 1 GW. For large commercial projects or utility-scale farms, it is advisable to verify current IEC certifications and confirm the availability of local after-sales service support. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/EX585-605TCB-144HC182BF-c92289346e55.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +45 W, lighter, +1.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +40 W, lighter, +1.6 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -45 W, lighter, +1.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +35 W, lighter, +1.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -50 W, lighter, +1.2 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +30 W, lighter, +1.2 pp | | [Exiom EX345AGR-182](https://comparepv.com/panel/exiom-ex345agr-182) | 345 W | -260 W, hotter, -10.0 pp | | [Exiom EX350AGR-182](https://comparepv.com/panel/exiom-ex350agr-182) | 350 W | -255 W, hotter, -9.9 pp | | [Exiom EX355AGR-182](https://comparepv.com/panel/exiom-ex355agr-182) | 355 W | -250 W, hotter, -9.7 pp | | [Exiom EX360AGR-182](https://comparepv.com/panel/exiom-ex360agr-182) | 360 W | -245 W, hotter, -9.5 pp | | [Exiom EX365AGR-182](https://comparepv.com/panel/exiom-ex365agr-182) | 365 W | -240 W, hotter, -9.3 pp | | [Exiom EX530MB-144BF](https://comparepv.com/panel/exiom-ex530mb-144bf) | 530 W | -75 W, hotter, -2.9 pp | | [Exiom EX535MB-144BF](https://comparepv.com/panel/exiom-ex535mb-144bf) | 535 W | -70 W, hotter, -2.7 pp | | [Exiom EX540MB-144BF](https://comparepv.com/panel/exiom-ex540mb-144bf) | 540 W | -65 W, hotter, -2.5 pp | | [Exiom EX545MB-144BF](https://comparepv.com/panel/exiom-ex545mb-144bf) | 545 W | -60 W, hotter, -2.3 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +25 W, cooler, +1.0 pp | --- Source: https://comparepv.com/panel/exiom-ex605tc-144hc182bf Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
