Compare JS Solar panels on ComparePV." source: "https://comparepv.com/reviews/js-solar" --- # JS Solar panels, *read off the datasheets* JS Solar has 137 modules in the database, from 200 to 670 Wp. Everything below is computed from those 137 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where JS Solar does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2011 - **Headquarters:** Jinhua, China 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 | 137 | models in the database | | Average efficiency | 20.0 % | across the catalogue | | Best efficiency | 22.4 % | their strongest module | | Power range | 200-670 Wp | smallest to largest | | Bifacial share | 9 % | 12 dual-sided models | | Average warranty | 25 years | guaranteed output term | ## 01. The top of the range The leaders of JS Solar'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 | [JS580N144](https://comparepv.com/panel/js-solar-js580n144) | 580 Wp | 22.4% (good) | | 2 | [JS435N108FB](https://comparepv.com/panel/js-solar-js435n108fb) | 435 Wp | 22.3% (good) | | 3 | [JS575N144](https://comparepv.com/panel/js-solar-js575n144) | 575 Wp | 22.3% (good) | | 4 | [JS570N144](https://comparepv.com/panel/js-solar-js570n144) | 570 Wp | 22.1% (good) | | 5 | [JS430N108FB](https://comparepv.com/panel/js-solar-js430n108fb) | 430 Wp | 22.0% (good) | - JS580N144 - Monocrystalline bifacial - JS435N108FB - Monocrystalline bifacial - JS575N144 - Monocrystalline bifacial - JS570N144 - Monocrystalline bifacial - JS430N108FB - Monocrystalline bifacial [Sort the whole catalogue by efficiency](https://comparepv.com/panels/js-solar?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [JS210MHC132-670](https://comparepv.com/panel/js-solar-js210mhc132-670) | 21.6% | 670 Wp | | 2 | [JS210MHC132-665](https://comparepv.com/panel/js-solar-js210mhc132-665) | 21.4% | 665 Wp | | 3 | [JS210MHC132-660](https://comparepv.com/panel/js-solar-js210mhc132-660) | 21.2% | 660 Wp | | 4 | [JS210MHC132-655](https://comparepv.com/panel/js-solar-js210mhc132-655) | 21.1% | 655 Wp | | 5 | [JS210MHC132-650](https://comparepv.com/panel/js-solar-js210mhc132-650) | 20.9% | 650 Wp | - JS210MHC132-670 - Monocrystalline - JS210MHC132-665 - Monocrystalline - JS210MHC132-660 - Monocrystalline - JS210MHC132-655 - Monocrystalline - JS210MHC132-650 - Monocrystalline [Sort the whole catalogue by power](https://comparepv.com/panels/js-solar?sort_by=power&sort_order=desc) ## 02.

What the catalogue is made of Shares are of the 137 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 | | --- | --- | --- | --- | | | Unknown | 55.5% | 76 | | | PERC | 38.7% | 53 | | | TOPCon | 5.8% | 8 | Unknown accounts for 55.5% of the catalogue - 76 of 137 modules. ### Efficiency spread share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | \<20% | 32.1% | 44 | | | 20-21% | 35.8% | 49 | | | 21-22% | 27.7% | 38 | | | 22-23% | 4.4% | 6 | ## 04.
