Bifacial Design and N-Type Half-Cells Structure Explained

These advanced features define the high-efficiency performance and extended durability of the HanerSun  HN18N-54HT445W 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.
