Bifacial Solar Panel | 705Wp | 40.70V | 22.70% | 2384x1303x35mm | 40HQ: 558Pieces
GRANKIA GT705W-132M topcon bifacial photovoltaic pv solar panels 705w is making it one of the most efficient solar panels on the market. This is achieved through the use of advanced Topcon technology, which allows for more efficient energy conversion.
The photovoltaic pv solar panels 705w is designed with a bifacial structure, which means it can absorb light from both the front and back sides of the panel. This allows for increased energy output, especially in situations where the panel is installed on a reflective surface.
With advanced cell architecture and innovative manufacturing techniques, the topcon bifacial photovoltaic pv solar panels 705w achieves impressive efficiency levels. It converts more sunlight into electricity, which is particularly beneficial for large-scale installations where maximizing space and output is essential.

Half-Cell Design
The solar panel features a half-cell design, which reduces electrical losses and increases energy output.
Multi-Busbar (MBB) Technology
The solar panel uses MBB technology, which reduces electrical resistance and increases energy output.
Low Temperature Coefficient
The photovoltaic pv solar panels have a low temperature coefficient, which means its energy output is less affected by high temperatures. This makes it an ideal choice for installations in warm climates.
High Salt Mist and Ammonia Resistance
The photovoltaic pv solar panels have a high resistance to salt mist and ammonia, making it suitable for use in coastal and agricultural areas.
Compatible with Popular Inverters
The solar panel is compatible with popular inverters from leading manufacturers, making it easy to integrate into existing solar systems.
