Sirius PV ELNSM54M-405-HC-HV 405W Bifacial Monocrystalline Solar Panel
Model ELNSM54M-405-HC-HV | Bifacial PERC | 120 Half-Cell Monocrystalline | Bifacial | 1500 V System Voltage
Product Overview
The Sirius PV ELNSM54M-405-HC-HV 405W bifacial monocrystalline solar panel delivers reliable power and strong long term performance for residential and commercial arrays. This high efficiency module uses advanced PERC bifacial cell technology to harvest energy from both the front and rear surfaces. System designers can benefit from a compact 1722 x 1134 mm footprint with a slim 35 mm frame, which simplifies handling and mounting. Module efficiency up to 20.74% helps maximize output where roof or ground space is limited. A durable anodized aluminium frame, tempered glass and robust encapsulation are engineered for harsh outdoor environments. With a 12 year product warranty and long term power guarantees, this panel is an excellent choice for dependable rooftop or ground mount systems. It is produced in Turkey by Sirius PV (Elin A.Ş), supporting projects that value European manufacturing expertise. The panel’s 1500 V system rating, low temperature coefficients and tight positive power tolerance support efficient string design and predictable energy yields.
Key Benefits
High power density for limited spaces: With a 405 Wp rating and up to 20.74% efficiency, strong output is delivered from a compact footprint, ideal for tight roofs and constrained sites.
Bifacial generation for higher yields: Bifacial PERC technology captures irradiance from the front and reflected light from the rear side, which can increase energy production on bright and reflective surfaces.
Proven long term reliability: A 12 year product warranty and power warranties of 93.95% at 10 years and 87.2% at 25 years support bankable project performance.
Stable performance in real conditions: Low temperature coefficients, a nominal operating temperature of 45±2 °C, and a wide operating range from -40 °C to 85 °C improve energy production in varied climates.
Robust mechanical design: Tempered anti reflection coated glass, a strong anodized aluminium frame and 3.2 mm glass thickness provide resistance to wind, snow and mechanical stress on demanding installations.
Flexible system integration: A 1500 V maximum system voltage, 25 A series fuse rating and bifacial architecture give designers flexibility for string lengths and mounting layouts in modern PV systems.
How It Works
This Sirius PV ELNSM54M-405-HC-HV bifacial monocrystalline solar panel converts sunlight into usable DC electricity through high efficiency PERC cells. When light hits the 120 monocrystalline cells, photons release electrons and generate an electrical current across the cell matrix. The bifacial design allows the rear side to use reflected light from the roof or ground, which helps increase total kWh output over the year. Optimized cell interconnection and low resistance busbars guide the current to the junction box and onward to inverters or charge controllers. Temperature behaviour, voltage and current are balanced so each string operates near maximum power point in real field conditions. Over time, slow power degradation and stable encapsulation support predictable performance for residential, commercial and light industrial projects.
Bifacial PERC cell operation: Each PERC monocrystalline cell converts direct sunlight on the front while the rear side responds to reflected irradiance. This configuration increases energy harvest without expanding the array footprint and suits bright surfaces such as white membranes, gravel or light concrete.
Maximum power tracking in strings: At standard test conditions, the module operates at 30.93 V and 13.1 A to reach 405 W. In a string, inverters use MPPT algorithms around these voltage and current values so combined modules work near their maximum power point across changing irradiance.
Thermal and environmental resilience: The panel is rated for ambient conditions from -40 °C to 85 °C, supporting harsh summers and winters. Low temperature coefficients for Pmax, Voc and Isc help limit power losses as module temperature rises during sunny periods.
