Astronergy 575W Bifacial Solar Panel

Astronergy 575W Bifacial Solar Panel – Astro N5 TOPCon Double Glass High Efficiency Module

The Astronergy 575W bifacial solar panel (model CHSM72N(DG)/F-BH) is a high-performance photovoltaic module engineered for commercial, industrial, and utility-scale solar installations requiring maximum efficiency, durability, and long-term reliability. Built using advanced N-Type TOPCon cell technology and a half-cut cell architecture, this Astronergy bifacial solar panel delivers excellent energy yield, reduced degradation, and improved system performance throughout its operational lifespan.

High Efficiency Astronergy 575W Solar Panel Performance

With a rated output of 575 watts under Standard Test Conditions (STC), the Astronergy 575W solar panel achieves a module efficiency of up to approximately 22.3%, allowing installers to maximise system output while reducing the number of modules required. The use of N-type monocrystalline TOPCon technology improves carrier mobility and reduces recombination losses, resulting in higher efficiency and better long-term performance compared to conventional P-type modules.

The Astronergy Astro N5 575W solar panel also features excellent low-light performance, allowing improved energy production during early mornings, late afternoons, and cloudy conditions.

Bifacial Double Glass Technology for Increased Energy Yield

This Astronergy bifacial solar module features dual glass construction combined with bifacial energy generation capability. The rear side of the panel captures reflected and diffused light from surrounding surfaces, increasing total system energy production beyond the rated front-side output. Depending on installation conditions, bifacial gain can significantly improve overall system performance and reduce levelised cost of energy (LCOE).

The robust double glass construction enhances resistance to environmental degradation, including moisture ingress, UV exposure, and temperature cycling. This improves mechanical stability and ensures consistent performance over long operating periods.

Electrical Specifications and System Compatibility

The Astronergy 575W bifacial solar panel is designed for modern high-voltage solar installations and supports a maximum system voltage of 1500V DC, allowing efficient string design and reduced balance-of-system costs.

Key electrical specifications at STC include a voltage at maximum power (Vmp) of approximately 42.94 V, a current at maximum power (Imp) of approximately 13.39 A, an open-circuit voltage (Voc) of approximately 51.10 V, and a short-circuit current (Isc) of approximately 14.19 A. These characteristics allow compatibility with a wide range of commercial and utility-grade string inverters when properly configured.

N-Type TOPCon Technology Advantages

The Astronergy N-Type TOPCon solar panel offers several advantages over conventional solar modules, including improved efficiency, reduced degradation rates, and better resistance to potential induced degradation (PID). N-type technology provides superior long-term performance stability and ensures consistent energy generation throughout the system lifespan.

The module also features a favourable temperature coefficient of -0.29% per °C, helping maintain stable output even in high ambient temperatures commonly experienced in solar installations across South Africa.

Mechanical Specifications and Build Quality

The Astronergy Astro N5 575W solar panel is designed for durability and structural strength. The module measures 2278 × 1134 × 30 mm and weighs approximately 32.1 kg. Its anodised aluminium frame provides excellent corrosion resistance and mechanical integrity, while the double glass design improves durability and reduces long-term degradation risks.

The module is rated for mechanical loads of up to 5400 Pa on the front side and 2400 Pa on the rear side, ensuring reliable performance in demanding environmental conditions such as strong wind or exposed installations.

Operating Conditions and System Integration

The Astronergy 575W bifacial module operates efficiently across a wide temperature range and supports modern solar system architectures. The module uses high-quality connectors (HCB40 standard or optional MC4-EVO2A), ensuring reliable electrical connections and compatibility with industry-standard solar cabling.

With a nominal module operating temperature (NMOT) of approximately 41°C ±2°C, the module provides stable operating performance under real-world conditions.

Warranty and Long-Term Performance Reliability

Astronergy supports the Astro N5 bifacial solar panel with 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, ensuring reliable long-term performance and return on investment.
