Compare Fellow Energy panels on ComparePV." source: "https://comparepv.com/reviews/fellow-energy" --- # Fellow Energy panels, *read off the datasheets* Fellow Energy is a solar energy technology manufacturer founded in 2020 in Gaziantep, Türkiye. The company specializes in the research, development, manufacturing, and sales of photovoltaic modules and solar cells, all of which are fully designed and produced domestically. Fellow Energy is... Everything below is computed from those 13 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Fellow Energy does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2020 - **Headquarters:** Gaziantep, Türkiye - **Employees:** 350+ - **Tier 1 bankable:** Yes (good) 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 | 13 | models in the database | | Average efficiency | 21.6 % | across the catalogue | | Best efficiency | 22.9 % | their strongest module | | Power range | 415-590 Wp | smallest to largest | | Bifacial share | 54 % | 7 dual-sided models | | Average warranty | 27 years | guaranteed output term | ## 01. The top of the range The leaders of Fellow Energy'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 | [FE72-18X(ND)](https://comparepv.com/panel/fellow-energy-fe72-18x-nd) | 590 Wp | 22.9% (good) | | 2 | [FE54-18X(N)-435W](https://comparepv.com/panel/fellow-energy-fe54-18x-n-435w) | 435 Wp | 22.3% (good) | | 3 | [FE54-18X(N)-430W](https://comparepv.com/panel/fellow-energy-fe54-18x-n-430w) | 430 Wp | 22.0% | | 4 | [FE54-18X(N)-425W](https://comparepv.com/panel/fellow-energy-fe54-18x-n-425w) | 425 Wp | 21.7% | | 5 | [FE72-18X 560W](https://comparepv.com/panel/fellow-energy-fe72-18x-560w) | 560 Wp | 21.7% | - FE72-18X(ND) - Monocrystalline bifacial - FE54-18X(N)-435W - Monocrystalline bifacial - FE54-18X(N)-430W - Monocrystalline bifacial - FE54-18X(N)-425W - Monocrystalline bifacial - FE72-18X 560W - Monocrystalline [Sort the whole catalogue by efficiency](https://comparepv.com/panels/fellow-energy?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [FE72-18X(ND)](https://comparepv.com/panel/fellow-energy-fe72-18x-nd) | 22.9% (good) | 590 Wp | | 2 | [FE72-18X 560W](https://comparepv.com/panel/fellow-energy-fe72-18x-560w) | 21.7% | 560 Wp | | 3 | [FE72-18X 555W](https://comparepv.com/panel/fellow-energy-fe72-18x-555w) | 21.5% | 555 Wp | | 4 | [FE72-18X 550W](https://comparepv.com/panel/fellow-energy-fe72-18x-550w) | 21.3% | 550 Wp | | 5 | [FE72-18X 545W](https://comparepv.com/panel/fellow-energy-fe72-18x-545w) | 21.1% | 545 Wp | - FE72-18X(ND) - Monocrystalline bifacial - FE72-18X 560W - Monocrystalline - FE72-18X 555W - Monocrystalline - FE72-18X 550W - Monocrystalline - FE72-18X 545W - Monocrystalline [Sort the whole catalogue by power](https://comparepv.com/panels/fellow-energy?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 13 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. [Cell technology across the market](https://comparepv.com/stats/cell-technology) ### Cell technology share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | TOPCon | 53.8% | 7 | | | PERC | 46.2% | 6 | TOPCon accounts for 53.8% of the catalogue - 7 of 13 modules. ### Efficiency spread share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | 20-21% | 7.7% | 1 | | | 21-22% | 76.9% | 10 | | | 22-23% | 15.4% | 2 | ## 04.
