Description

Product Description

The JA Solar 545W solar panel is built using advanced monocrystalline PERC half cell technology to deliver high power output and improved energy efficiency. The half cell configuration reduces electrical losses and improves performance in shaded conditions while increasing overall module reliability.

This panel is part of the JA Solar Deep Blue series and is engineered to provide excellent temperature performance, ensuring stable energy generation even in hot climates. Its robust construction with tempered glass and a corrosion resistant aluminium frame allows the module to withstand harsh weather conditions including high wind and snow loads.

With high conversion efficiency and durable materials, the JA Solar 545W module is suitable for rooftop installations, ground mount solar systems, and large scale solar farms. It is compatible with most grid tied and hybrid inverter systems and provides long term reliability supported by industry standard warranties.
