Compare Q-SUN Solar panels on ComparePV." source: "https://comparepv.com/reviews/q-sun-solar" --- # Q-SUN Solar panels, *read off the datasheets* Qn-SOLAR officially launched its global PV business in 2022. The company is headquartered in Shanghai, China, and has four manufacturing bases in China. As a professional and integrated company, Qn-SOLAR operates in various fields of PV upstream and downstream, achieving an annual... Everything below is computed from those 111 datasheets: no score out of ten, no ranking of brands against each other, and nothing a manufacturer can pay to change. Where Q-SUN Solar does not publish a figure, it is left out of the average rather than assumed. ## The company - **Founded:** 2014 - **Headquarters:** 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 | 111 | models in the database | | Average efficiency | 21.9 % | across the catalogue | | Best efficiency | 23.7 % (good) | their strongest module | | Power range | 395-730 Wp | smallest to largest | | Bifacial share | 68 % | 76 dual-sided models | | Average warranty | 29 years | guaranteed output term | ## 01.

What the catalogue is made of Shares are of the 111 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:** Solid portfolio of 111 panels - **Strength:** High-efficiency panels available (up to 23.7%) - **Strength:** Strong bifacial lineup - 68% of portfolio supports dual-sided generation - **Strength:** Strong warranty coverage averaging 29 years - **Strength:** High-power panels available (up to 730W) for commercial applications ### Where it is thin - **Watch out:** Limited adoption of latest cell technologies (TOPCon/HJT) ## 05.
