Axitec 590W bifacial N-Type TOPCon Solar Panel AC-590TGB/144TS
The AXITEC AC-590TGB/144TS is a 590 W, high-performance bifacial module built on n-type TOPCon half-cells with a rugged glass/glass laminate. With 22.84% module efficiency, a 1,500 V DC system rating, and a 30 mm silver aluminum frame, it’s engineered for long-term reliability and strong energy yield in C&I and large residential arrays.
Key Benefits
High Output & Efficiency: 590 W STC with 22.84% module efficiency for dense layouts.
Bifacial Gain: Rear-side contribution can lift power; BNPI test points show up to ~654 W at specified rear irradiance.
Durable Double-Glass: 2.0 mm front + 2.0 mm rear glass improves fire safety and PID resistance.
Robust Mechanics: Test loads up to 113 psf (front) / 50 psf (rear) for harsh conditions.
Special Technology
n-Type TOPCon Half-Cells (144): Low LID, strong low-light behavior; SMBB layout for reduced resistive loss.
High-Voltage Platform: 1,500 V DC rating enables longer strings and BOS savings.
IP68 Components: Stäubli MC4-EVO2 connectors, IP68 junction box with 3 bypass diodes.
Warranty
30-Year Manufacturer Warranty & 30-Year Linear Performance Guarantee.
Best Uses
Commercial & Utility DG: Carports, rooftops, and ground mounts targeting low LCOE.
Large Residential: High-power, high-efficiency modules where roof area is limited.
Bifacial Design and N-Type Half-Cells Structure Explained
These advanced features define the high-efficiency performance and extended durability of the Axitec AC-590TGB/144TS 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.
