Sirius PV ELNSM54M-415-HC-HV 415W Bifacial Monocrystalline Solar Panel
Model ELNSM54M-415-HC-HV | PERC Monocrystalline | 120 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The Sirius PV ELNSM54M-415-HC-HV 415W bifacial monocrystalline solar panel is engineered for high efficiency and long term performance in demanding projects. This 415 watt module uses advanced PERC cell technology and a half cut cell layout to deliver reliable energy output in residential, commercial, and utility scale systems. With a maximum module efficiency of 21.25%, it helps achieve strong power density where roof or ground space is limited. The panel is built around 182×91 mm mono cells, arranged as 120 half cells, and protected by 3.2 mm tempered glass with anti reflection coating. Installers and owners benefit from robust mechanical strength, a maximum system voltage of 1500 V, and precise power tolerance from 0 to +1.23%. A 12 year product warranty and long term linear power warranty support dependable energy production over decades. This Sirius PV module from Elin A.Ş in Turkey is a versatile choice for modern solar arrays that demand efficiency, durability, and attractive lifetime returns.
Key Benefits
High power density for limited space: The 415 Wp output and up to 21.25% efficiency allow more energy per square meter, ideal for tight rooftops and compact ground mounts.
Bifacial design for increased yield: Bifacial construction captures light from the front and rear surfaces, boosting energy production on reflective surfaces and in high albedo environments.
Stable long term performance: A total degradation rate of about 0.51% per year supports 93.95% power after 10 years and 87.2% after 25 years, improving lifetime energy yield.
Robust mechanical design: The module uses 3.2 mm tempered glass, an anodized aluminium frame, and a 1500 V system rating, delivering reliability in a wide range of climates and mounting conditions.
Optimised electrical characteristics: The 31.16 V operating voltage and 13.32 A current at maximum power enable flexible string sizing while the tight positive tolerance enhances energy harvest.
Reliable performance in real conditions: Competitive low light behavior and carefully controlled temperature coefficients support stable energy output across seasons and varying irradiance levels.
How It Works
This Sirius PV bifacial monocrystalline solar panel converts sunlight into usable DC electricity through advanced PERC half cells on both faces of the module. When sunlight hits the 182 mm mono cells on the front side, photons are absorbed and generate an electric current that flows through multi busbar conductors. Simultaneously, the bifacial rear side captures reflected and diffuse light from the ground or nearby surfaces, providing additional power gain under the right conditions. The module operates at a maximum power point of 415 Wp, with a voltage of 31.16 V and a current of 13.32 A, feeding DC power into the inverter. The inverter then converts this DC into AC power for on site loads or export to the grid, depending on the system design. Carefully engineered temperature coefficients, mechanical components, and protective glass ensure steady output in a wide range of outdoor environments.
PERC monocrystalline half cell architecture: Each of the 120 PERC half cells uses a passivated rear surface to reflect unused light back into the cell, increasing the chance of photon absorption and electron generation. The half cut design reduces resistive losses and improves performance at higher currents, while also limiting the impact of local shading on the string.
Bifacial energy capture: The module is built as a bifacial unit, allowing the rear side to collect light reflected from bright surfaces such as concrete, light gravel, snow, or white roofing. This rear side contribution increases total energy generation over the year, especially in open rack ground mounts and elevated rooftop installations where albedo can be optimised.
Thermal and electrical optimisation: The panel’s temperature coefficients, including -0.34% per °C for Pmax and -0.26% per °C for Voc, limit power loss as module temperature rises in strong sun. A positive only power tolerance from 0 to +1.23% ensures that every shipped module matches or exceeds the nameplate rating, supporting consistent field performance and streamlined system design.
