Bifacial Design, N-Type Half-Cells, and Dual Glass Structure Explained

These advanced features define the high-efficiency performance and extended durability of the Thornova TS-BGT66(620)-G11 solar panel:

Bifacial Technology
This bifacial module is engineered to capture solar energy from both the front and rear sides. While the front absorbs direct sunlight, the rear side collects reflected light from surrounding surfaces such as concrete, snow, or sand. This dual-sided exposure increases overall energy harvest, significantly boosting total output and system efficiency—especially in high-albedo environments.

N-Type Half-Cell Architecture
The panel utilizes N-Type monocrystalline cells with a half-cut layout, offering superior efficiency and thermal performance compared to traditional P-Type cells. N-Type cells are inherently more resistant to light-induced degradation (LID) and offer improved electron mobility, resulting in higher efficiency and longer operational stability. The half-cell configuration minimizes resistive losses and enhances energy yield even under partial shading.

Dual-Glass Structure
Encased between two layers of tempered glass, this panel provides exceptional mechanical strength and environmental protection. The dual-glass architecture enhances resistance to moisture, UV exposure, and extreme weather conditions like high winds and heavy snow. This design minimizes degradation and extends module lifespan, making it ideal for demanding installations requiring long-term reliability.
