Compare S-Energy panels on ComparePV." source: "https://comparepv.com/reviews/s-energy" --- # S-Energy panels, *read off the datasheets* S-Energy has 91 modules in the database, from 365 to 665 Wp. Everything below is computed from those 91 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where S-Energy does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2011 - **Headquarters:** Seoul, South Korea 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 | 91 | models in the database | | Average efficiency | 21.0 % | across the catalogue | | Best efficiency | 22.4 % | their strongest module | | Power range | 365-665 Wp | smallest to largest | | Bifacial share | 77 % | 70 dual-sided models | | Average warranty | 28 years | guaranteed output term | ## 01. The top of the range The leaders of S-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 | [SL65-78TDP-625R](https://comparepv.com/panel/s-energy-sl65-78tdp-625r) | 625 Wp | 22.4% (good) | | 2 | [SL65-72TDP-575R](https://comparepv.com/panel/s-energy-sl65-72tdp-575r) | 575 Wp | 22.3% (good) | | 3 | [SL65-78TDP-620R](https://comparepv.com/panel/s-energy-sl65-78tdp-620r) | 620 Wp | 22.2% (good) | | 4 | [SL65-72TDP-570R](https://comparepv.com/panel/s-energy-sl65-72tdp-570r) | 570 Wp | 22.1% (good) | | 5 | [SL65-54TDP-430R](https://comparepv.com/panel/s-energy-sl65-54tdp-430r) | 430 Wp | 22.0% (good) | - SL65-78TDP-625R - Monocrystalline bifacial - SL65-72TDP-575R - Monocrystalline bifacial - SL65-78TDP-620R - Monocrystalline bifacial - SL65-72TDP-570R - Monocrystalline bifacial - SL65-54TDP-430R - Monocrystalline bifacial [Sort the whole catalogue by efficiency](https://comparepv.com/panels/s-energy?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [SL85-66BDL-665R](https://comparepv.com/panel/s-energy-sl85-66bdl-665r) | 21.4% | 665 Wp | | 2 | [SL85-66BDL-660R](https://comparepv.com/panel/s-energy-sl85-66bdl-660r) | 21.3% | 660 Wp | | 3 | [SL85-66BDL-655R](https://comparepv.com/panel/s-energy-sl85-66bdl-655r) | 21.1% | 655 Wp | | 4 | [SL85-66BDL-650R](https://comparepv.com/panel/s-energy-sl85-66bdl-650r) | 20.9% | 650 Wp | | 5 | [SL85-66BDL-645R](https://comparepv.com/panel/s-energy-sl85-66bdl-645r) | 20.8% | 645 Wp | - SL85-66BDL-665R - Monocrystalline bifacial - SL85-66BDL-660R - Monocrystalline bifacial - SL85-66BDL-655R - Monocrystalline bifacial - SL85-66BDL-650R - Monocrystalline bifacial - SL85-66BDL-645R - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/s-energy?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 91 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 | | --- | --- | --- | --- | | | PERC | 59.3% | 54 | | | TOPCon | 27.5% | 25 | | | Unknown | 13.2% | 12 | PERC accounts for 59.3% of the catalogue - 54 of 91 modules. ### Efficiency spread share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | 20-21% | 54.9% | 50 | | | 21-22% | 37.4% | 34 | | | 22-23% | 7.7% | 7 | ## 04.
