Compare Corab panels on ComparePV." source: "https://comparepv.com/reviews/corab" --- # Corab panels, *read off the datasheets* Corab is a leading Polish manufacturer of steel photovoltaic structures and a distributor of devices from renowned brands in the renewable energy sector. They design and produce assembly structures for various types of roofs and surfaces and are also a distributor of... Everything below is computed from those 5 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Corab does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 1993 - **Headquarters:** Olsztyn, Poland - **Annual capacity:** 2.5 GW - **Employees:** 300+ 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 | 5 | models in the database | | Average efficiency | 20.6 % | across the catalogue | | Best efficiency | 21.0 % | their strongest module | | Power range | 360-410 Wp | smallest to largest | | Bifacial share | 0 % | 0 dual-sided models | | Average warranty | 25 years | guaranteed output term | ## 01. The top of the range The leaders of Corab'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 | [EC410M-10-108FB-V](https://comparepv.com/panel/corab-ec410m-10-108fb-v) | 410 Wp | 21.0% | | 2 | [EC405M-10-108B-V 405 Wp](https://comparepv.com/panel/corab-ec405m-10-108b-v-405-wp) | 405 Wp | 20.9% | | 3 | [EC405M-10-108B-V](https://comparepv.com/panel/corab-ec405m-10-108b-v) | 405 Wp | 20.9% | | 4 | [EC405M-10-108B](https://comparepv.com/panel/corab-ec405m-10-108b) | 405 Wp | 20.9% | | 5 | [ENCOR EC360M-6-120FB](https://comparepv.com/panel/corab-encor-ec360m-6-120fb) | 360 Wp | 19.3% | - EC410M-10-108FB-V - Monocrystalline - EC405M-10-108B-V 405 Wp - Monocrystalline - EC405M-10-108B-V - Monocrystalline - EC405M-10-108B - Monocrystalline - ENCOR EC360M-6-120FB - Monocrystalline [Sort the whole catalogue by efficiency](https://comparepv.com/panels/corab?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [EC410M-10-108FB-V](https://comparepv.com/panel/corab-ec410m-10-108fb-v) | 21.0% | 410 Wp | | 2 | [EC405M-10-108B-V 405 Wp](https://comparepv.com/panel/corab-ec405m-10-108b-v-405-wp) | 20.9% | 405 Wp | | 3 | [EC405M-10-108B-V](https://comparepv.com/panel/corab-ec405m-10-108b-v) | 20.9% | 405 Wp | | 4 | [EC405M-10-108B](https://comparepv.com/panel/corab-ec405m-10-108b) | 20.9% | 405 Wp | | 5 | [ENCOR EC360M-6-120FB](https://comparepv.com/panel/corab-encor-ec360m-6-120fb) | 19.3% | 360 Wp | - EC410M-10-108FB-V - Monocrystalline - EC405M-10-108B-V 405 Wp - Monocrystalline - EC405M-10-108B-V - Monocrystalline - EC405M-10-108B - Monocrystalline - ENCOR EC360M-6-120FB - Monocrystalline [Sort the whole catalogue by power](https://comparepv.com/panels/corab?sort_by=power&sort_order=desc) ## 02. By what the array is for Three cuts of the same catalogue, each ordered by efficiency inside its band. An empty column means the brand does not build for that case. ### For a house roof 380-460 Wp | # | Panel | power | efficiency | | --- | --- | --- | --- | | 1 | [EC410M-10-108FB-V](https://comparepv.com/panel/corab-ec410m-10-108fb-v) | 410 Wp | 21.0% | | 2 | [EC405M-10-108B-V 405 Wp](https://comparepv.com/panel/corab-ec405m-10-108b-v-405-wp) | 405 Wp | 20.9% | | 3 | [EC405M-10-108B-V](https://comparepv.com/panel/corab-ec405m-10-108b-v) | 405 Wp | 20.9% | | 4 | [EC405M-10-108B](https://comparepv.com/panel/corab-ec405m-10-108b) | 405 Wp | 20.9% | - EC410M-10-108FB-V - Monocrystalline - EC405M-10-108B-V 405 Wp - Monocrystalline - EC405M-10-108B-V - Monocrystalline - EC405M-10-108B - Monocrystalline ## 03. What the catalogue is made of Shares are of the 5 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.

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:** Strong warranty coverage averaging 25 years - **Strength:** Established manufacturer with 33+ years of experience - **Strength:** Large-scale production capacity of 2.5 GW ### Where it is thin - **Watch out:** Average efficiency of 20.6% is below the industry leading edge - **Watch out:** Limited bifacial panel options - **Watch out:** No high-power panels (500W+) available for commercial use - **Watch out:** Limited adoption of latest cell technologies (TOPCon/HJT) ## 05.
