The Tiger Neo series of N-type TOPCon-based panels from JinkoSolar achieve the maximum efficiency rating at 22.95% under ideal conditions, whereas the most efficient N-type panels currently on the market all have efficiency percentages above 21%. When the temperature exceeds 77 degrees Fahrenheit, Tiger Neo beats out the competition with a temperature coefficient of 0.29%/°C.
Three N-type TOPCon solar panel model series are available from JinkoSolar under the brand name Tiger Neo. The most recent range from the firm, the Tiger Neo 66-cells, features greater watt ratings and a little improved efficiency. It offers up to 620 watts at a 22.95% efficiency, compared to the 54-cell Tiger Neo residential panel’s up to 450 watts at a 22.52% efficiency and a 0.29%/°C temperature coefficient.
In addition to having a better efficiency, N-type TOPCon has significantly less degradation than PERC, such as LID and LeTID, thanks to its doping and diffusion characteristics. The first 12-month deterioration of TOPCon arrays, on average, is between 0.5% and 0.6%, whereas that of PERC arrays is between 1.5 and 1.8%, according to tracking comparison data collected and recorded from existing n-type and p-type projects.
The temperature coefficient is yet another important element that hastens the adoption of TOPCon panels. The panel’s efficiency will decrease by the coefficient rating % for every degree Celsius when the temperature climbs over 25. JinkoSolar’s Tiger Neo, for instance, has a temperature coefficient value of 0.29%/°C. Its efficiency will decline by 2.9%/°C when the panel temperature rises by 10 degrees Celsius (50F), which is frequent in hot sunshine. In contrast, a P-type panel with a temperature coefficient of 0.35%/°C will see a loss in efficiency of 3.4%/°C, or 17% greater decreases. In essence, when it’s heated, it generates less electricity.
