Bifacial Solar Panel | 610Wp | 40.80V | 21.55% | 2172x1303x30/35 mm | 40HQ: 720 / 620 Pieces
GRANKIA GT610W-120M best dual glass topcon bifacial 610w pv module makes it an ideal choice for both residential and commercial installations.
The bifacial design allows the 610w pv module to capture sunlight from both the front and rear sides, significantly increasing energy yield. This feature is particularly beneficial in environments with reflective surfaces, such as snow or sand, where additional light can be harnessed.
The dual glass design enhances durability and longevity. It provides superior protection against environmental factors such as moisture, dust, and UV radiation, ensuring that the module maintains its performance over time.

Topcon Technology
The innovative Topcon technology used in the 610w pv module enhances the efficiency of the solar cells by reducing recombination losses. This results in higher energy conversion rates and improved overall performance.
Enhanced Aesthetics
The sleek design of the dual glass module not only contributes to its durability but also offers a modern and aesthetically pleasing appearance, making it suitable for various architectural styles.
Temperature Coefficient
The module features a low temperature coefficient, which means it performs better in high-temperature conditions compared to traditional solar panels. This characteristic helps maintain energy output during hot weather, ensuring consistent performance.
Advanced Glass Technology
The panel uses high-transmission tempered glass, which is not only durable but also allows more sunlight to penetrate into the solar cells. This contributes to a higher power output and improves the overall efficiency of the module.
IP68 Rating (Water and Dust Resistance)
The topcon 610w pv module features an IP68 rating, which means it is highly resistant to water and dust ingress. This level of protection ensures that the panel can continue to function efficiently even in challenging outdoor environments, such as in regions with high humidity, rainfall, or dust storms.
