Jinko Solar’s Edge in Harsh Climates: Insights from Edgard Abou Kheir, Technical Services Manager – MENA

What are Jinko’s latest PV technologies, and how do they tackle efficiency issues in high-temperature regions?

Jinko Solar prioritizes technological advancement and reliability in the solar market. We’ve proven this with almost 150GW of TOPCon shipments since 2021 until date. Our R&D team are always working on optimizing the technology and improving the cells to always achieve higher power classes and efficiency levels. Our continuous R&D efforts have culminated in the Tiger Neo 3.0, featuring 20BB, HCP, and MAX technologies, achieving a 24.8% efficiency and 670W power. Those improvements also take into consideration reliability and performance under harsh environmental conditions, for this reason we perform extensive reliability testing on each new technology before its release to the market to simulate its reliability specially for high temperature and humidity regions. In addition to that, we also focus on doing field tests in our region to compare the performance of different types of technologies in different weather conditions.

Jinko’s TOPCon outperformed competitors in Qatar’s extreme climate. What key factors contributed to this success?

Although HJT technology holds theoretical advantages, JinkoSolar’s TOPCon modules demonstrated superior performance in Qatar’s harsh conditions. This was attributed to JinkoSolar’s advanced technology, strategic material choices, optimized module design, and excellent thermal stability, ultimately yielding higher Performance Ratios, Specific Yields and operational efficiency. The recorded numbers and results also confirmed that not all manufacturers have the same TOPCon technology, and its performance can differ.

How do Jinko’s PV modules resist degradation in MENA’s heat and humidity, and what role does BOM play in reliability?

Jinko Solar’s PV modules are engineered to mitigate degradation mechanisms prevalent in the Middle East and North Africa (MENA) region’s extreme heat and humidity through a combination of advanced Bill of Materials (BOM) selection and sophisticated module design.

• Encapsulation Material Selection: The choice of encapsulant is critical in humid environments.
• Double-Glass Module Design:  The double-glass design provides enhanced structural integrity and thermal management.
• BOM and Reliability Interplay: The careful selection of interconnect ribbons, junction box materials, and other BOM components further contributes to the overall reliability and longevity of the modules. Each component is rigorously tested to ensure compatibility and performance under extreme conditions.

How does Jinko’s bifacial dual-glass design compare to traditional PV modules, and what are its cost implications for utility projects?

Jinko Solar’s bifacial dual-glass modules boost energy yield compared to traditional modules by capturing sunlight on both sides, lowering the Levelized Cost of Electricity (LCOE) for utility projects. Dual-glass construction enhances durability, reducing long-term costs. Recent glass price reductions made the prices of the glass lower and more competitive. Jinko Solar’s MAX technology, which improves rear-side generation, further enhance economic and technical viability by increasing the bifacial factor and energy generation from the rear side. While installation requires optimization for rear-side capture, the increased energy output and longevity make Jinko Solar’s bifacial dual-glass a cost-effective and more reliable choice for utility-scale solar projects.
