Compare Exiom panels on ComparePV." source: "https://comparepv.com/reviews/exiom" --- # Exiom panels, *read off the datasheets* Exiom is a European solar module manufacturer with production facilities in Spain. The company focuses on producing high-quality photovoltaic modules for the European market, emphasizing local manufacturing and short supply chains. Everything below is computed from those 39 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Exiom does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2019 - **Headquarters:** Barcelona, Spain - **Annual capacity:** 0.5 GW - **Employees:** 100 Company facts, not datasheet figures. Tier 1 is a financier's bankability list, and says nothing about how a panel performs. ## Key figures | Measure | Value | Note | | --- | --- | --- | | Panels | 39 | models in the database | | Average efficiency | 20.1 % | across the catalogue | | Best efficiency | 23.4 % (good) | their strongest module | | Power range | 270-605 Wp | smallest to largest | | Bifacial share | 59 % | 23 dual-sided models | | Average warranty | 29 years | guaranteed output term | ## 01. The top of the range The leaders of Exiom's own catalogue on the two figures a specification sheet leads with. Neither is a verdict: the most efficient module in a range is rarely the one that suits a given roof. ### Most efficient module efficiency | # | Panel | power | efficiency | | --- | --- | --- | --- | | 1 | [EX605TC-144HC182BF](https://comparepv.com/panel/exiom-ex605tc-144hc182bf) | 605 Wp | 23.4% (good) | | 2 | [EX455TC-108HC](https://comparepv.com/panel/exiom-ex455tc-108hc) | 455 Wp | 23.3% (good) | | 3 | [EX600TC-144HC182BF](https://comparepv.com/panel/exiom-ex600tc-144hc182bf) | 600 Wp | 23.2% (good) | | 4 | [EX450TC-108HC](https://comparepv.com/panel/exiom-ex450tc-108hc) | 450 Wp | 23.0% (good) | | 5 | [EX595TC-144HC182BF](https://comparepv.com/panel/exiom-ex595tc-144hc182bf) | 595 Wp | 23.0% (good) | - EX605TC-144HC182BF - Monocrystalline bifacial - EX455TC-108HC - Monocrystalline - EX600TC-144HC182BF - Monocrystalline bifacial - EX450TC-108HC - Monocrystalline - EX595TC-144HC182BF - Monocrystalline bifacial [Sort the whole catalogue by efficiency](https://comparepv.com/panels/exiom?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [EX605TC-144HC182BF](https://comparepv.com/panel/exiom-ex605tc-144hc182bf) | 23.4% (good) | 605 Wp | | 2 | [EX600TC-144HC182BF](https://comparepv.com/panel/exiom-ex600tc-144hc182bf) | 23.2% (good) | 600 Wp | | 3 | [EX595TC-144HC182BF](https://comparepv.com/panel/exiom-ex595tc-144hc182bf) | 23.0% (good) | 595 Wp | | 4 | [EX590TC-144HC182BF](https://comparepv.com/panel/exiom-ex590tc-144hc182bf) | 22.8% (good) | 590 Wp | | 5 | [EX585TC-144HC182BF](https://comparepv.com/panel/exiom-ex585tc-144hc182bf) | 22.6% (good) | 585 Wp | - EX605TC-144HC182BF - Monocrystalline bifacial - EX600TC-144HC182BF - Monocrystalline bifacial - EX595TC-144HC182BF - Monocrystalline bifacial - EX590TC-144HC182BF - Monocrystalline bifacial - EX585TC-144HC182BF - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/exiom?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 39 modules in the database, counted once each. A power ladder of one module counts as its rungs, which is why a large catalogue is not the same as a wide one.
