Bifacial Solar Panel | 600Wp | 40.30V | 21.20% | 2172x1303x30/35 mm | 40HQ: 720 / 620 Pieces
GRANKIA GT600W-120M high module efficiency topcon 600w solar panel can meet the energy demands of both residential and commercial applications. Its high wattage allows for fewer panels to be installed, reducing overall system costs and space requirements.
The 600w solar panel boasts an impressive efficiency rating, often exceeding 21.20%. This means that a greater percentage of sunlight is converted into usable electricity, making it one of the most efficient options available on the market.
The high module efficiency topcon 600w solar panel can capture sunlight on both its front and rear sides, thanks to its bifacial design. This feature enables it to harness reflected sunlight from the roof or surrounding surfaces, increasing total energy production. As a result, users can expect higher energy yields, especially in installations where the ground surface or roof reflects a significant amount of sunlight.

Low Light Performance
This rooftop 600w solar panel is designed to perform exceptionally well in low-light conditions, such as on overcast days or during early mornings and late afternoons. The high efficiency ensures that it can still generate a significant amount of power, even when the sunlight intensity is lower than typical peak hours.
Enhanced Anti-Reflective Coating
The solar photovoltaic module is equipped with an anti-reflective coating that minimizes light loss due to reflection. This coating ensures that more light is absorbed into the solar cells, contributing to higher energy conversion efficiency and better overall performance in a range of lighting conditions.
Bifacial Design
The bifacial design of this solar module allows it to capture sunlight from both the front and back sides, further increasing its energy generation capabilities. This feature is particularly advantageous in environments where reflections from the ground or nearby surfaces can contribute to additional energy production.
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.
The topcon 600w solar panel 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.
