Compare Selfa panels on ComparePV." source: "https://comparepv.com/reviews/selfa" --- # Selfa panels, *read off the datasheets* Selfa has 34 modules in the database, from 310 to 550 Wp. Everything below is computed from those 34 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Selfa does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 1992 - **Headquarters:** Bydgoszcz, Poland 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 | 34 | models in the database | | Average efficiency | 20.5 % | across the catalogue | | Best efficiency | 22.6 % | their strongest module | | Power range | 310-550 Wp | smallest to largest | | Bifacial share | 9 % | 3 dual-sided models | | Average warranty | 28 years | guaranteed output term | ## 01. The top of the range The leaders of Selfa'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 | [SV120M.3.4-500](https://comparepv.com/panel/selfa-sv120m-3-4-500) | 500 Wp | 22.6% (good) | | 2 | [SV120M.2.4-500](https://comparepv.com/panel/selfa-sv120m-2-4-500) | 500 Wp | 22.6% (good) | | 3 | [SV108M.2.4-450](https://comparepv.com/panel/selfa-sv108m-2-4-450) | 450 Wp | 22.5% (good) | | 4 | [SV108M.3.4-450](https://comparepv.com/panel/tcl-zhonghuan-sv108m-3-4-450) | 450 Wp | 22.5% (good) | | 5 | [SV108M.2.4-440](https://comparepv.com/panel/selfa-sv108m-2-4-440) | 440 Wp | 22.0% (good) | - SV120M.3.4-500 - Monocrystalline bifacial - SV120M.2.4-500 - Monocrystalline bifacial - SV108M.2.4-450 - Monocrystalline bifacial - SV108M.3.4-450 - Monocrystalline - SV108M.2.4-440 - Monocrystalline [Sort the whole catalogue by efficiency](https://comparepv.com/panels/selfa?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [SV144M.5.3-550](https://comparepv.com/panel/selfa-sv144m-5-3-550) | 21.3% | 550 Wp | | 2 | [SV144M.5.3-545](https://comparepv.com/panel/selfa-sv144m-5-3-545) | 21.1% | 545 Wp | | 3 | [SV144M.5.3-540](https://comparepv.com/panel/selfa-sv144m-5-3-540) | 20.9% | 540 Wp | | 4 | [SV144M.5.1-540](https://comparepv.com/panel/tcl-zhonghuan-sv144m-5-1-540) | 20.9% | 540 Wp | | 5 | [SV120M.3.4-500](https://comparepv.com/panel/selfa-sv120m-3-4-500) | 22.6% (good) | 500 Wp | - SV144M.5.3-550 - Monocrystalline - SV144M.5.3-545 - Monocrystalline - SV144M.5.3-540 - Monocrystalline - SV144M.5.1-540 - Monocrystalline - SV120M.3.4-500 - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/selfa?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 34 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 | 73.5% | 25 | | | N-type | 26.5% | 9 | PERC accounts for 73.5% of the catalogue - 25 of 34 modules. ### Efficiency spread share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | \<20% | 38.2% | 13 | | | 20-21% | 23.5% | 8 | | | 21-22% | 20.6% | 7 | | | 22-23% | 17.6% | 6 | ## 04. Strengths and gaps Both lists are derived from the figures above rather than written about the brand. A gap here is a gap in what is published, which is not always a gap in what is built. ### What this catalogue is good at - **Strength:** High-efficiency panels available (up to 22.6%) - **Strength:** Strong warranty coverage averaging 28 years - **Strength:** Established manufacturer with 34+ years of experience ### Where it is thin - **Watch out:** Average efficiency of 20.5% is below the industry leading edge - **Watch out:** Limited bifacial panel options - **Watch out:** Limited adoption of latest cell technologies (TOPCon/HJT) ## 05. In short > **Selfa:** Selfa is a solid option, offering 34 panels suitable for both residential and commercial buyers. With an average efficiency of 20.5% and top models reaching 22.6%, their panels deliver competitive performance. ### Common questions #### Is Selfa a good solar panel manufacturer?
