The Power and Efficiency of Sunway Solar’s 550w Solar Panel

The Power and Efficiency of Sunway Solar’s 550w Solar Panel

At Sunway Solar, we take pride in offering high-performance solar panels that provide exceptional power and efficiency. Our company is committed to delivering top-quality products and services to meet the needs of our customers. One of our standout offerings is the Sunway 550w Solar Panel, specifically the SW550M-144 model. This solar panel is designed to harness the maximum energy from sunlight, enabling you to generate clean and renewable electricity for various applications.

Our solar panel boasts impressive specifications and dimensions. With its dimensions measuring at 2279*1133*35mm and weight at 31.5kg, it offers a sturdy and compact design that is suitable for both residential and commercial installations. Furthermore, our panel has obtained important certifications such as CE, TUV, and INMETRO, ensuring its reliability and compliance with industry standards.


Advanced Technologies for Optimal Performance

To ensure optimal performance, our 550w Solar Panel incorporates advanced technologies that enhance efficiency and aesthetics. One of these technologies is half-cell technology. By dividing the cells into halves, we minimize power loss caused by shading and improve the overall performance of the panel. This allows our solar panel to operate efficiently even in challenging environments.


Another key technology integrated into our solar panel is Multi-busbar (MBB) technology. By utilizing multiple busbars instead of the traditional two, we increase the efficiency of the module. This innovative approach not only maximizes power generation but also enhances the visual appeal of the panel.


We also employ Passivated Emitter and Rear Cell (PERC) technology in our solar panel. This advanced cell design involves a passivation process on the rear side of the cell, along with precise laser grooving. As a result, the efficiency of the cell is significantly improved, leading to higher overall system performance.


Key Electrical Parameters and Performance

Understanding the electrical parameters of our 550w Solar Panel is essential in evaluating its performance. The SW530M-144~550M-144 models offer consistent and reliable power output. With a maximum power range of 530W to 550W, these panels are capable of generating substantial electricity from the sun’s energy.


The voltage and current ratings of our solar panel are optimized for efficient energy conversion. The maximum power voltage (Vmp/V) ranges from 41.70V to 42.10V, while the maximum power current (Imp/A) ranges from 12.71A to 13.07A. These values ensure that your solar panel operates at its peak performance, delivering the maximum power possible.


With an efficiency rating ranging from 20.50% to 21.30%, our solar panel provides impressive conversion rates, maximizing the amount of electricity generated. Additionally, our panels have a power tolerance range of 0~+5W, ensuring consistent and reliable performance.



In conclusion, Sunway Solar’s 550w Solar Panel is a powerful and efficient solution for harnessing solar energy. Our company is dedicated to providing high-quality products and services to meet the needs of our customers. With advanced technologies such as half-cell, Multi-busbar, and PERC, our solar panels deliver optimal performance and aesthetic appeal. The detailed electrical parameters and impressive power output of our panels make them a reliable choice for various applications. Trust Sunway Solar for top-quality solar products that will bring you closer to a greener and more sustainable future.
