PRODUCT OVERVIEW
The Maple Leaf 5N N-Type TOPCon Bifacial Dual Glass Solar Module (640W) is engineered with the latest Maple Leaf S-TOPCo 2.0 Technology, offering exceptional solar panel efficiency, enhanced reliability, and a long solar panel lifespan. Designed with N-type solar cells, this advanced module eliminates Light Induced Degradation (LID), ensuring consistent and reliable solar power generation for decades.
Its bifacial dual glass structure enables up to 30% additional energy output by capturing sunlight from both sides, making it one of the best solar panels for cloudy and low-light conditions thanks to its superior weak illumination response. With a maximum efficiency of 23.71% and excellent solar cell temperature coefficient performance, this module delivers high output even in high-temperature working environments.
KEY FEATURES:
-
N-Type Solar Cell with Zero LID – No light-induced degradation, guaranteeing long-term energy yield.
-
TOPCon Solar Technology (S-TOPCo 2.0) – Advanced passivating contact cells ensure higher reliability and zero leakage current.
-
Bifacial Dual Glass Design – Increases energy yield by up to 30% with rear-side power generation.
-
Superior Weak Illumination Response – Optimized performance even under cloudy, foggy, or low-light conditions.
-
Better Temperature Coefficient – High power generation under high operating temperatures.
-
30-Year Power Output Warranty – Backed by SunEvo with 15 years materials warranty + 30 years performance warranty.
-
High Reliability Solar Panels – ISO 9001:2015 Quality Management certified, IEC61215/61730 solar certifications, and more.
