UE provides three technological pathways for solar panels. You can explore their advantages to choose the one that best fits your needs. Of course, the quickest way is to click here to directly contact our engineers.   PERC（Passivated Emitter Rear Cell）:    - Cost-effectiveness: The PERC technology boasts mature manufacturing processes, akin to traditional solar cell production, resulting in lower manufacturing costs. This positions PERC as a cost-effective choice, particularly for large-scale solar projects.    - Stability in Performance: Widely applied in commercial settings, PERC technology demonstrates stable performance, making it suitable for projects requiring long-term reliability.    - Widespread Application: With its cost-effectiveness and stable performance, PERC technology has found extensive applications in both commercial and industrial sectors, making it especially suitable for large-scale solar ventures.   TOPCon（Tunnel Oxide Passivated Contact）:    - High Conversion Efficiency: TOPCon cells consistently achieve high conversion efficiencies, making them ideal for projects with stringent requirements for energy output.    - Low-Temperature Manufacturing: The manufacturing process involves lower temperatures, contributing to energy savings and environmental friendliness, making it suitable for environmentally conscious projects.    - High-Temperature Stability: TOPCon cells exhibit stability in high-temperature environments, making them advantageous in regions with hot climates.    - Extended Lifespan: TOPCon cells generally boast an extended lifespan, often surpassing 25 years.   HJT（Hetero junction Technology）:    - High Conversion Efficiency and Low Light Degradation: HJT technology typically achieves high conversion efficiency, excelling particularly in low-light conditions.    - Adaptability to Temperature Changes: HJT cells remain stable in high-temperature environments, making them suitable for regions with challenging climates.    - Suitability for Space-Limited Projects: Due to their high conversion efficiency and relatively small size, HJT cells are well-suited for space-limited projects such as rooftop installations.   - Extended Lifespan: HJT cells commonly have an extended lifespan, often exceeding 30 years, ensuring sustained high conversion efficiency.
