I. Key Findings
1. Leading Total Power Generation
The Qatar demonstration project completed power generation comparison tests from July 7, 2026, to August 22, 2026. Measured data shows that during the test period, JinkoSolar’s Tiger Neo 3.0 modules achieved a total specific yield of 226.02 kWh/kW, while N-type BC modules recorded 221.77 kWh/kW. The Tiger Neo 3.0 modules delivered an average 1.92% power gain per watt, demonstrating stable and reliable overall power generation performance under extreme tropical desert conditions.
2. High Bifaciality Rate Advantages Stand Out
Data broken down by irradiance level shows that in the high-irradiance range above 1000W/m2, the Tiger Neo 3.0 achieved a power generation gain of 2.01%. The Tiger Neo 3.0’s bifaciality rate reached a maximum of 85% ± 5%, whereas N-type BC modules—where both positive and negative busbars are located on the rear side—typically have a bifaciality rate of only around 70% due to shading losses caused by metal electrodes and the patterning process. Qatar’s terrain consists primarily of desert and sandy land with virtually no rainwater runoff. The high reflectivity of the sandy surface provides a stable source of reflected irradiance on the module’s rear side. A higher bifaciality ratio means greater ability to capture rear-side irradiance, thereby generating higher power output gains during periods of high irradiance.
3. Low-Temperature Operation Ensures High-Temperature Power Generation
The Middle East’s desert regions experience year-round high temperatures, with ground temperatures in Qatar approaching 50°C during the test period, and the operating temperature of solar modules directly affects power generation efficiency and long-term reliability. Monitoring data from the full testing cycle shows that the Tiger Neo 3.0’s average operating temperature is 0.36°C lower than that of N-type BC modules. A lower operating temperature means less power loss due to temperature, enabling the Tiger Neo 3.0 to maintain stable power output even in extremely high-temperature environments.
II. Project Background
To verify the modules’ actual power generation capacity under desert climates and explore their application value in typical Middle Eastern power plant scenarios, JinkoSolar collaborated with QEERI (Qatar Environment and Energy Research Institute), a national research institution in Qatar, to conduct a comparative field test between the Tiger Neo 3.0 and N-type BC modules in Qatar. Located in a desert region, Qatar features typical climatic characteristics such as high irradiance, high temperatures, high humidity,aridity with little rainfall, and high surface albedo, making it a rigorous testing environment for evaluating module power generation performance, weather resistance, and reliability. At the same time, the Middle East has emerged as a key, rapidly growing region in the global PV market, with large-scale ground-mounted power plant construction continuing to advance. Local field test data done with well-known and reputable third parties provides important reference value for equipment selection in the region. Therefore, selecting Qatar as the site for this project ensures that the test results more closely reflect the actual operating conditions of projects in the Middle East.
III. Project Design
To ensure that the comparison results are objective and valid, this project employs a string-level parallel comparison approach, strictly controlling variables to ensure data validity.
1. Test Samples: Six Jinko Tiger Neo 3.0 modules and six N-type BC modules were selected. Both sets of modules measure 2382 × 1134 mm;
2. Installation Method: Both sets of modules were installed using the same mounting structure and under identical installation conditions. The installation tilt angle was 22° for both, with consistent orientation and no surrounding obstructions. The ground consisted of typical desert sand, ensuring essentially identical irradiance conditions;
3. Purpose of Comparison: To reflect the power generation capacity under typical Middle Eastern power plant conditions at a desert ground-mounted power plant, with a focus on evaluating the comprehensive power generation performance of the two module types in environments characterized by high irradiance, high temperatures, high humidity and highly reflective surfaces;
4. Monitoring Period: July 7, 2026, to August 22, 2026, fully covering the summer high-temperature period; no rainfall was recorded during the test period, with clear skies throughout the entire cycle and stable irradiance conditions;
5. Data Assurance: Data collection and monitoring for the project were conducted by QEERI (Qatar Environment and Energy Research Institute), a national research institution in Qatar affiliated with Hamad bin Khalifa University. With extensive research experience in the reliability of photovoltaic modules in arid regions, QEERI provides authoritative endorsement of the objectivity and impartiality of the test data;

IV. Data Insights
During the nearly one-and-a-half-month testing period, actual test data showed that JinkoSolar’s Tiger Neo 3.0 modules achieved a total specific yield of 226.02 kWh/kW, while N-type BC modules recorded 221.77 kWh/kW, indicating that the Tiger Neo 3.0 delivered an average 1.92% increase in power output per watt. During the testing period, the local weather was predominantly sunny and partly cloudy, with abundant solar radiation. The comprehensive advantages of the Tiger Neo 3.0 can be verified from the following three dimensions.
1. Stable power generation gain throughout the entire cycle: During the testing period, the Tiger Neo 3.0 consistently maintained a positive power generation gain over the N-type BC modules, with a power generation gain per watt of 1.92%. It did not experience any decline in gain due to extreme high temperatures or intense solar radiation, demonstrating stable and reliable power generation performance.
2. Significant Advantages in High-Irradiance Bifaciality: In high-irradiance ranges above 1000W/m2, the Tiger Neo 3.0 achieved a power generation gain of 2.01%. The high surface reflectivity of the Qatari desert provides considerable additional irradiance to the rear of the modules. Modules with high bifaciality can more fully capture and convert this rear-reflected irradiance, thereby achieving higher power generation gains during periods of high irradiance.
3. Lower Operating Temperature Ensures Power Generation in High-Temperature Conditions: Throughout the entire testing cycle, the Tiger Neo 3.0’s average operating temperature was 0.36°C lower than that of N-type BC modules. This lower operating temperature provides a strong guarantee for power generation and long-term reliability in high-temperature environments.
V. Analysis of Operating Principles
From a technical perspective, Jinko Tiger Neo 3.0 employs a unique MAX graphical enhancement technology. Through the selective layout of the rear poly layer, it significantly reduces rear-side irradiation loss and achieves a high bifaciality of up to 85% ± 5%. The ground at the Qatar power plant consists primarily of desert sand, which has a high reflectivity and can provide considerable reflected irradiance to the rear of the modules. A higher bifaciality ratio means the modules are better able to capture reflected light on the rear side, converting more rear-side irradiance into actual power generation.
Compared to N-type BC modules, the Tiger Neo 3.0’s advantage in bifaciality is even more pronounced. Since both the positive and negative grid lines of BC cells are located on the rear side, the metal electrodes on the back, combined with the shading losses caused by the patterning process, result in a bifaciality ratio typically around 70% only. Consequently, the power generation benefits from rear-side irradiation are relatively limited in highly reflective ground environments such as deserts. The difference in bifaciality between the Tiger Neo 3.0 and N-type BC modules, combined with Qatar’s intense sunlight and highly reflective sandy terrain, directly translates to a 2.01% power gain in high-irradiance ranges exceeding 1000W/m2.
In terms of temperature performance, the Tiger Neo 3.0 exhibits same power temperature coefficient, and its average operating temperature throughout the entire test cycle was 0.36°C lower than that of N-type BC modules, effectively reducing power loss in high-temperature environments and ensuring stable power generation under Qatar’s high-temperature conditions. This lower operating temperature is a validation of the datasheet values and is a proof that even if both technologies have same temperature coefficient on datasheet, the actual performance could not be the same under real world conditions.
