This model delivers a high maximum power output of 520W with a module efficiency of 19.3%. Despite its robust performance, it weighs only 8.6KG and has an ultra-thin profile of 2mm, which significantly simplifies installation and reduces structurally-induced roof stress.
Yes. The panel is designed to operate reliably in harsh environments, featuring a certified operating temperature range from -40℃ up to 85℃, and it conforms to Class A application standards.
Our manufacturing processes utilize state-of-the-art production equipment and strictly comply with global quality management systems, holding certifications that adhere to ISO, TUV, and CE standards.
We employ heavy-duty, impact-resistant industrial packaging and crates to secure all solar panels. This prevents micro-cracks and structural damage during loading, sea shipping, and local distribution.
Every client is supported by a comprehensive after-sales service policy, which includes prompt response channels, product installation guidance, and ongoing technical troubleshooting.
