Elerix EXS-550MHC-B 550W PERC Monocrystalline Half-Cut Solar Panel
Model EXS-550MHC-B | PERC Monocrystalline | 144 Half-Cut Cells | Monofacial | 1500V System Voltage
Product Overview
The Elerix EXS-550MHC-B 550W PERC monocrystalline half-cut solar panel is designed for projects that demand high efficiency and long term reliability. This powerful module uses advanced mono PERC half cut cells to deliver a panel efficiency of 21.3% while maintaining a sleek black appearance. With a maximum system voltage of 1500 V and robust construction, it fits both residential and commercial installations. A linear power warranty ensures strong performance, with 92% output guaranteed after 12 years and 83% after 30 years. The EXS-550MHC-B is produced by Elerix Ltd. in the Czech Republic and is built to handle demanding climates including deserts, farmlands and coastal areas. Heavy snow and wind load resistance, together with an IP68 junction box, support dependable energy production throughout the panel lifetime.
Key Benefits
High power density: The 550 Wp output and 21.3% efficiency help maximise energy yield from limited roof or ground space.
Reliable long term performance: A 12 year product warranty and 30 year linear power warranty support investment security for owners.
Durable mechanical design: The tempered glass, anodized aluminium frame and IP68 junction box provide strong protection in harsh weather.
Enhanced safety and compatibility: A 1500 V system rating and 25 A series fuse rating suit modern string inverters and large scale arrays.
Optimised cell technology: PERC half cut cells reduce resistive losses and hot spot risk, improving real world performance and reliability.
How It Works
Sunlight hits the Elerix EXS-550MHC-B solar panel and is absorbed by its monocrystalline PERC half cut cells. The cells convert this solar energy into direct current electricity, which is then routed through the integrated junction box and DC cables to the inverter. At standard test conditions the module delivers up to 550 Wp, with a maximum power voltage of 42 V and current of 13.1 A. The high efficiency design means more of the incident light becomes usable power, even when installation space is limited. Temperature coefficients have been optimised so that power loss remains moderate as cell temperature rises. The robust frame, glass and encapsulation work together to protect the cells from mechanical stress and moisture, supporting stable performance over decades of operation.
Mono PERC half-cut cell architecture: Each 182 × 91 mm monocrystalline PERC cell is cut into half cells and arranged in a 144 cell layout. This layout reduces electrical resistance and lowers operating temperature, which increases output and decreases the risk of hot spots over time.
Energy flow and system integration: Generated DC power flows from the cell strings to the IP68 junction box, which contains three bypass diodes. These diodes help the panel continue operating when partial shading occurs, while the 1500 V system rating allows longer strings and reduced cabling costs.
Temperature and environmental resilience: The panel operates from -40°C to 85°C and uses a tempered glass front with 3.2 mm thickness. Power, voltage and current temperature coefficients are engineered so performance remains stable in heat, cold and changing irradiance throughout the year.
