When evaluating the comprehensive performance of a solar panel, in addition to hard indicators such as conversion efficiency, power output, and temperature coefficient, "light decay" performance is an extremely critical but often overlooked parameter. Light-Induced Degradation (LID) represents the degree of attenuation of the power output of solar panels during the initial use or long-term operation, which directly affects its power generation income and return on investment. This article will focus on the core issue of "How is the light decay performance of Jinko Tiger solar panels?" and conduct a systematic analysis from multiple dimensions such as technical principles, actual data, comparative advantages, and long-term benefits.
1. What is light decay? Why is it so important?
Light decay refers to the performance degradation of the output power of solar cell modules due to physical changes in materials after they begin to be exposed to sunlight. Generally, there are two types of light decay:
Initial light decay (LID): occurs between a few hours and a few days after the module is initially exposed to sunlight, and generally has the greatest impact;
Long-term light decay (LeTID): The phenomenon that the performance of the module continues to decline over time, especially in high temperature and high humidity environments.
The more severe the light decay, the greater the gap between the actual power generation capacity and the nominal power, and the economic benefits of the system will be greatly reduced. Therefore, excellent light decay control capability is an important indicator for evaluating high-end solar modules.
2. Overview of Jinko Tiger solar panel light decay performance
The Jinko Tiger series covers multiple technical routes such as P-type PERC and N-type TOPCon. Among them, Tiger Pro mainly uses P-type technology, while Tiger Neo is based on N-type TOPCon cells. Both perform well in light decay control, as follows:
2.1 Tiger Pro (P-type PERC) light decay performance
The light decay in the first year is controlled within 2%: thanks to Jinko's optimization of the stability of the PERC passivation layer, the generation of oxygen-boron complexes is reduced, and LID is effectively alleviated.
The average annual power decay rate does not exceed 0.55%: far better than the industry average (usually between 0.7% and 0.8%).
2.2 Tiger Neo (N-type TOPCon) light decay performance
The light decay rate in the first year is less than 1%: N-type technology is naturally free of boron doping and almost no oxygen-boron complexes are produced, so LID is extremely low.
The average annual power attenuation rate is controlled within 0.4%, which can achieve 30 years of linear power output guarantee, far exceeding P-type modules.
Jinko Tiger Neo series is an industry benchmark product in the field of N-type modules. Its excellent anti-light decay ability brings users longer-term and more stable power generation benefits.
3. Technical principle: How does Jinko control light decay?
Jinko Solar can achieve such excellent light decay control mainly thanks to the following key technologies:
3.1 High-quality silicon wafer control
The Tiger series uses high-purity silicon wafers with low metal impurities to effectively reduce defect sites, inhibit recombination centers, and reduce light decay rate.
3.2 Laser non-destructive cutting technology
The Tiger Neo series uses non-destructive laser cutting technology to avoid micro-cracks on the edge of the cell, improve the strength of the cell, and reduce stress. 3.3 Passivation contact structure optimization
High-efficiency passivation layer (such as SiOx, SiNx) and selective doping process are used to optimize the charge recombination mechanism and reduce LID and LeTID.
3.4 Battery Packaging Solution
The packaging design of the Tiger series focuses on air tightness, thermal expansion matching and material life, improves the anti-aging and anti-humidity performance of the components, and controls long-term light decay from the source.
4. Why is low light decay so important to users?
Choosing components with good light decay control is not only about pursuing "panel quality", but also a long-term guarantee for system benefits:
More stable power generation: low light decay means higher available power output, especially in scenarios with high electricity prices or power restrictions.
Clearer return on investment: long-term benefits are more predictable, suitable for projects such as financial leasing, EPC contracting, and power station asset transfer.
More durable components: low-attenuation components have strong structural stability and low hot spot risks, and are suitable for extreme climates such as high temperature and high humidity.
Lower system operation and maintenance costs: due to slow performance degradation, the frequency of component replacement is reduced, reducing the burden of later operations.
5. Application Case: Advantages of Jinko Tiger Components in High Attenuation Environments
In high-temperature and high-ultraviolet regions such as the Middle East, Africa, and Southeast Asia, component light decay is particularly obvious. The Jinko Tiger Neo modules have been successfully applied to multiple ground power station projects with high light, high temperature and humidity. The actual operation data shows that:
The power generation in the first year far exceeded the design expectations;
The power attenuation in the subsequent five years remained within 0.35%;
The overall IRR of the project was increased by more than 6% compared with the conventional PERC solution.
This fully proves the superior light decay resistance of the Tiger series modules, providing investors with stable and reliable returns.
In today's increasingly homogenized solar modules, "light decay" has become a key indicator to distinguish high-quality products. Jinko Energy's Jinko Tiger series, especially Tiger Neo, has achieved industry-leading low light decay performance through N-type TOPCon technology and advanced manufacturing processes.
Whether it is a home user pursuing long-term power generation benefits or a commercial or power station investor focusing on asset stability, Jinko Tiger solar panels are a trustworthy choice. In the future, as the global photovoltaic market evolves towards high efficiency and long life, the Tiger series will continue to lead the development trend of green energy with its stable, low decay and high yield characteristics.
