Compare YS Solar panels on ComparePV." source: "https://comparepv.com/reviews/ys-solar" --- # YS Solar panels, *read off the datasheets* Guangdong Yaosheng Solar Technology Co., Ltd. (YS SOLAR) is a national high-tech enterprise specializing in the R&D, production, sales, and service of photovoltaic and solar thermal products. The company is a wholly-owned subsidiary of Guangdong Yaosheng-Yifang Group. YS Solar has become a... 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 YS Solar does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2009 - **Headquarters:** Meizhou City, Guangdong Province, 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 | 5 | models in the database | | Average efficiency | 20.4 % | across the catalogue | | Best efficiency | 21.0 % | their strongest module | | Power range | 330-350 Wp | smallest to largest | | Bifacial share | 0 % | 0 dual-sided models | | Average warranty | - years | guaranteed output term | ## 01. The top of the range The leaders of YS 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 | [YS350SM-90](https://comparepv.com/panel/ys-solar-ys350sm-90) | 350 Wp | 21.0% | | 2 | [YS345SM-90](https://comparepv.com/panel/ys-solar-ys345sm-90) | 345 Wp | 20.7% | | 3 | [YS340SM-90](https://comparepv.com/panel/ys-solar-ys340sm-90) | 340 Wp | 20.4% | | 4 | [YS335SM-90](https://comparepv.com/panel/ys-solar-ys335sm-90) | 335 Wp | 20.1% | | 5 | [YS330SM-90](https://comparepv.com/panel/ys-solar-ys330sm-90) | 330 Wp | 19.8% | - YS350SM-90 - Monocrystalline - YS345SM-90 - Monocrystalline - YS340SM-90 - Monocrystalline - YS335SM-90 - Monocrystalline - YS330SM-90 - Monocrystalline [Sort the whole catalogue by efficiency](https://comparepv.com/panels/ys-solar?sort_by=efficiency&sort_order=desc) ### Highest power nameplate output | # | Panel | efficiency | power | | --- | --- | --- | --- | | 1 | [YS350SM-90](https://comparepv.com/panel/ys-solar-ys350sm-90) | 21.0% | 350 Wp | | 2 | [YS345SM-90](https://comparepv.com/panel/ys-solar-ys345sm-90) | 20.7% | 345 Wp | | 3 | [YS340SM-90](https://comparepv.com/panel/ys-solar-ys340sm-90) | 20.4% | 340 Wp | | 4 | [YS335SM-90](https://comparepv.com/panel/ys-solar-ys335sm-90) | 20.1% | 335 Wp | | 5 | [YS330SM-90](https://comparepv.com/panel/ys-solar-ys330sm-90) | 19.8% | 330 Wp | - YS350SM-90 - Monocrystalline - YS345SM-90 - Monocrystalline - YS340SM-90 - Monocrystalline - YS335SM-90 - Monocrystalline - YS330SM-90 - Monocrystalline [Sort the whole catalogue by power](https://comparepv.com/panels/ys-solar?sort_by=power&sort_order=desc) ## 02. 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. [Cell technology across the market](https://comparepv.com/stats/cell-technology) ### Cell technology share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | Unknown | 100.0% | 5 | Unknown accounts for 100.0% of the catalogue - 5 of 5 modules. ### Efficiency spread share of the catalogue | # | Panel | share | panels | | --- | --- | --- | --- | | | \<20% | 20.0% | 1 | | | 20-21% | 60.0% | 3 | | | 21-22% | 20.0% | 1 | ## 03. 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. ### Where it is thin - **Watch out:** Average efficiency of 20.4% 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) ## 04. In short > **YS Solar:** YS Solar is a solid option, offering 5 panels suitable for residential installations. With an average efficiency of 20.4% and top models reaching 21.0%, their panels deliver competitive performance. ### Common questions #### Is YS Solar a good solar panel manufacturer?
