Compare Renewsys panels on ComparePV." source: "https://comparepv.com/reviews/renewsys" --- # Renewsys panels, *read off the datasheets* RenewSys is the first integrated manufacturer of Solar PV Modules and its key components - Encapsulants, Backsheets, and Solar PV Cells. Established in 2012, RenewSys is the renewable energy arm of the ENPEE Group, a diversified global conglomerate. They have manufacturing facilities... Everything below is computed from those 45 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Renewsys does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2011 - **Headquarters:** Mumbai, India - **Annual capacity:** 2.5 GW - **Employees:** 1071 - **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 | 45 | models in the database | | Average efficiency | 22.6 % | across the catalogue | | Best efficiency | 23.6 % (good) | their strongest module | | Power range | 415-650 Wp | smallest to largest | | Bifacial share | 100 % | 45 dual-sided models | | Average warranty | 30 years | guaranteed output term | ## 01. The top of the range The leaders of Renewsys'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 | [DESERV Extreme 144X-610](https://comparepv.com/panel/renewsys-deserv-extreme-144x-610) | 610 Wp | 23.6% (good) | | 2 | [DESERV Extreme 132X 635](https://comparepv.com/panel/renewsys-deserv-extreme-132x-635) | 635 Wp | 23.5% (good) | | 3 | [DESERV Extreme 144X-605](https://comparepv.com/panel/renewsys-deserv-extreme-144x-605) | 605 Wp | 23.4% (good) | | 4 | [DESERV Extreme 132X 630](https://comparepv.com/panel/renewsys-deserv-extreme-132x-630) | 630 Wp | 23.4% (good) | | 5 | [DESERV EXTREME 156X-650](https://comparepv.com/panel/renewsys-deserv-extreme-156x-650) | 650 Wp | 23.3% (good) | - DESERV Extreme 144X-610 - Monocrystalline bifacial - DESERV Extreme 132X 635 - Monocrystalline bifacial - DESERV Extreme 144X-605 - Monocrystalline bifacial - DESERV Extreme 132X 630 - Monocrystalline bifacial - DESERV EXTREME 156X-650 - Monocrystalline bifacial [Sort the whole catalogue by efficiency](https://comparepv.com/panels/renewsys?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [DESERV EXTREME 156X-650](https://comparepv.com/panel/renewsys-deserv-extreme-156x-650) | 23.3% (good) | 650 Wp | | 2 | [DESERV EXTREME 156X-645](https://comparepv.com/panel/renewsys-deserv-extreme-156x-645) | 23.1% (good) | 645 Wp | | 3 | [DESERV EXTREME 156X-640](https://comparepv.com/panel/renewsys-deserv-extreme-156x-640) | 22.9% (good) | 640 Wp | | 4 | [DESERV Extreme 132X 635](https://comparepv.com/panel/renewsys-deserv-extreme-132x-635) | 23.5% (good) | 635 Wp | | 5 | [DESERV EXTREME 156X-635](https://comparepv.com/panel/renewsys-deserv-extreme-156x-635) | 22.8% (good) | 635 Wp | - DESERV EXTREME 156X-650 - Monocrystalline bifacial - DESERV EXTREME 156X-645 - Monocrystalline bifacial - DESERV EXTREME 156X-640 - Monocrystalline bifacial - DESERV Extreme 132X 635 - Monocrystalline bifacial - DESERV EXTREME 156X-635 - Monocrystalline bifacial [Sort the whole catalogue by power](https://comparepv.com/panels/renewsys?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 45 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.
