Compare ECODELTA panels on ComparePV." source: "https://comparepv.com/reviews/ecodelta" --- # ECODELTA panels, *read off the datasheets* EcoDelta is a French developer of wind and solar energy projects. They offer expertise in project management and financing to maximize energy output. The company strives to promote, develop, and operate decentralized renewable electricity projects. 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 ECODELTA does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2002 - **Headquarters:** La Ciotat, France 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 | 21.1 % | across the catalogue | | Best efficiency | 22.5 % | their strongest module | | Power range | 395-550 Wp | smallest to largest | | Bifacial share | 23 % | 3 dual-sided models | | Average warranty | 26 years | guaranteed output term | ## 01. The top of the range The leaders of ECODELTA'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 | [ECO-450M-54LHC-DGBF](https://comparepv.com/panel/ecodelta-eco-450m-54lhc-dgbf) | 450 Wp | 22.5% (good) | | 2 | [ECO-445M-54LHC-DGBF](https://comparepv.com/panel/ecodelta-eco-445m-54lhc-dgbf) | 445 Wp | 22.3% (good) | | 3 | [ECO-440M-54LHC-DGBF](https://comparepv.com/panel/ecodelta-eco-440m-54lhc-dgbf) | 440 Wp | 22.0% (good) | | 4 | [ECO-550M-72LHC](https://comparepv.com/panel/ecodelta-eco-550m-72lhc) | 550 Wp | 21.3% | | 5 | [ECO-415M-60SB](https://comparepv.com/panel/ecodelta-eco-415m-60sb) | 415 Wp | 21.2% | - ECO-450M-54LHC-DGBF - Monocrystalline bifacial - ECO-445M-54LHC-DGBF - Monocrystalline bifacial - ECO-440M-54LHC-DGBF - Monocrystalline bifacial - ECO-550M-72LHC - Monocrystalline - ECO-415M-60SB - Monocrystalline [Sort the whole catalogue by efficiency](https://comparepv.com/panels/ecodelta?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [ECO-550M-72LHC](https://comparepv.com/panel/ecodelta-eco-550m-72lhc) | 21.3% | 550 Wp | | 2 | [ECO-545M-72LHC](https://comparepv.com/panel/ecodelta-eco-545m-72lhc) | 21.1% | 545 Wp | | 3 | [ECO-540M-72LHC](https://comparepv.com/panel/ecodelta-eco-540m-72lhc) | 20.9% | 540 Wp | | 4 | [ECO-535M-72LHC](https://comparepv.com/panel/ecodelta-eco-535m-72lhc) | 20.7% | 535 Wp | | 5 | [ECO-530M-72LHC](https://comparepv.com/panel/ecodelta-eco-530m-72lhc) | 20.5% | 530 Wp | - ECO-550M-72LHC - Monocrystalline - ECO-545M-72LHC - Monocrystalline - ECO-540M-72LHC - Monocrystalline - ECO-535M-72LHC - Monocrystalline - ECO-530M-72LHC - Monocrystalline [Sort the whole catalogue by power](https://comparepv.com/panels/ecodelta?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 | 61.5% | 8 | | | PERC | 38.5% | 5 | TOPCon accounts for 61.5% of the catalogue - 8 of 13 modules. ### Efficiency spread share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | 20-21% | 53.8% | 7 | | | 21-22% | 23.1% | 3 | | | 22-23% | 23.1% | 3 | ## 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 22.5%) - **Strength:** Strong warranty coverage averaging 26 years - **Strength:** Established manufacturer with 24+ years of experience ## 05.
