Astronergy 625W Bifacial Solar Panel – Astro N5 N-Type TOPCon High Efficiency Module

The Astronergy 625W bifacial solar panel (model CHSM78N(DG)/F-BH) is part of the advanced Astro N5 610–630W series, engineered for high-performance commercial, industrial, and utility-scale solar installations. Built using N-type monocrystalline TOPCon cell technology and a half-cut cell configuration, this 625W Astronergy solar panel delivers strong efficiency, excellent temperature performance, and reliable long-term energy production.

High Output 625W Solar Panel Performance

With a rated output of 625 watts under Standard Test Conditions (STC), the Astronergy 625W bifacial module achieves a module efficiency of approximately 22.4%. This high power rating allows system designers to reduce the number of modules required while maintaining strong overall system output.

Electrical specifications at STC include a voltage at maximum power (Vmp) of 46.29 V, current at maximum power (Imp) of 13.50 A, open circuit voltage (Voc) of 56.01 V, and short circuit current (Isc) of 14.11 A. These characteristics make the 625W Astronergy panel suitable for high-voltage string configurations up to 1500V DC when properly designed.

N-Type TOPCon Technology Advantages

The Astronergy Astro N5 625W solar panel uses N-type TOPCon cell technology, offering improved efficiency and enhanced long-term performance compared to conventional P-type modules. N-type cells provide lower degradation rates, improved resistance to Potential Induced Degradation (PID), and more stable energy production over time.

The panel features a favourable temperature coefficient of -0.29% per °C, reducing output losses in high ambient temperatures. This makes the Astronergy 625W bifacial solar panel particularly well suited to hot climates and large ground-mounted installations.

Bifacial Double Glass Construction

This Astronergy bifacial solar module features durable double glass construction (2.0 mm front and rear), enabling power generation from both the front and rear surfaces. The rear side captures reflected and diffused light from the surrounding environment, increasing total energy yield depending on installation conditions.

Integrated rear-side power gain can significantly improve system performance, particularly when installed above reflective ground surfaces or on elevated mounting structures.

Mechanical Strength and Durability

The Astronergy 625W bifacial panel is built for structural integrity and long-term durability. The module measures 2465 × 1134 × 30 mm and weighs approximately 34.7 kg. The silver anodised aluminium frame enhances corrosion resistance and mechanical stability.

The module is rated for mechanical test loads of up to 5400 Pa on the front side and 2400 Pa on the rear side, ensuring dependable performance in high-wind or exposed installations.

Electrical and Operating Parameters

The Astronergy 625W solar panel supports a maximum system voltage of 1500V DC and a maximum series fuse rating of 30A. It includes three bypass diodes and an IP68-rated junction box for enhanced environmental protection.

The nominal module operating temperature (NMOT) is approximately 41°C ±2°C, ensuring stable real-world operating conditions. Standard connectors include HCB40 (with MC4-EVO2A optional), ensuring compatibility with industry-standard cabling systems.

Warranty and Long-Term Performance

The Astronergy Astro N5 625W bifacial solar panel is backed by a 15-year product warranty and a 30-year linear power output warranty. The module is designed to maintain at least 87.4% of its original rated output after 30 years of operation, providing strong long-term investment protection.
