400W All Black Solar Panels Supplier
Luan 400W all-black solar panels with PERC (Passivated Emitter and Rear Cell) technology have the following features:
High Efficiency: PERC technology increases the efficiency of photovoltaic conversion by adding a passivation film on the back side of the cell. 400W all-black solar panels typically produce more power in the same area, making them suitable for installations with limited square footage.
Aesthetically pleasing design: The all-black design makes the panels more aesthetically pleasing when mounted on roofs or other structures, especially for residential or commercial projects seeking a high-quality appearance.
Excellent low-light performance: PERC cells perform well in low-light conditions (e.g., morning, dusk, or cloudy days) and are able to continue generating electricity, extending the operating time of the solar panel.
Low temperature coefficient: PERC solar panels have a low temperature coefficient, which means that the efficiency of the panels decreases less in high temperature environments, enabling them to maintain high power generation performance in various climatic conditions.
Lower photoluminescence degradation (LID): PERC technology effectively reduces photoluminescence degradation phenomenon, which prolongs the service life of the panel, while maintaining a high initial efficiency.
Longer life: PERC panels typically have a longer warranty and lifetime, providing more than 20 years of reliable power generation.
