Model SV120M.3.2-365 | Monocrystalline PERC Half-Cut | 120 Half-Cell PERC | Monofacial | 1000V System Voltage
The Selfa SV120M.3.2-365 solar panel delivers reliable 365W performance in a compact, high efficiency format designed for demanding European conditions. This monocrystalline half-cut PERC module is engineered by Polish manufacturer Selfa GE S.A. for residential and commercial rooftop projects seeking strong output from limited roof space. With panel efficiency up to 20 percent, it converts sunlight into electricity with very little wasted surface area across the 120 half cut cells. The module combines proven PERC cell technology, 9 busbar design and a self cleaning textured glass surface to increase long term yield. A linear power warranty ensures 91.8 percent output after ten years and 83 percent output after twenty five years, which supports stable energy production across the full lifetime of the system. Installers and owners benefit from a robust IP68 junction box, 3.2 mm tempered anti reflection glass and tested resistance to wind, snow and harsh environmental exposure.
High power density for limited roof space: The 365W output and 20 percent efficiency allow more energy production from a compact footprint, which supports higher yield on small residential roofs or constrained commercial arrays.
Half-cut PERC technology for better performance: Advanced monocrystalline PERC half cells reduce resistive losses and improve efficiency under real world conditions, which helps maintain strong production even when operating temperatures rise.
Reliable output with low annual degradation: A total degradation rate of about 0.68 percent per year is supported by a linear power warranty, which maintains at least 91.8 percent power after ten years and 83 percent after twenty five years.
Durable construction for harsh weather: The 3.2 mm tempered glass with anti reflection coating, IP68 junction box and robust frame are tested for high wind and snow loads, which helps protect the module during storms and heavy winter conditions.
European manufacturing and strong product support: Produced by Selfa GE S.A. in Poland, the panel includes a twelve year product warranty and a twenty five year power warranty, which offers long term peace of mind for installers and system owners.
The Selfa SV120M.3.2-365 solar panel converts incident sunlight into usable direct current electricity using monocrystalline PERC half cells wired in a high efficiency series parallel layout. Each of the 120 half cut cells generates voltage when photons strike the silicon, which releases electrons and drives current through the integrated 9 busbar grid. The panel operates at a maximum power point of 34.1 volts and 10.71 amperes under standard test conditions, giving a nominal power of 365 watts. Bypass diodes inside the IP68 junction box help limit power loss during partial shading by allowing current to flow around shaded cell strings. The anti reflection tempered glass improves light transmission into the cells, while the self cleaning surface helps reduce soiling losses over time. Generated DC power is routed through MC4 compatible connectors and 4 mm² solar cables to the inverter, which then converts the energy into AC power for on site loads or export to the grid. Performance is maintained across a temperature range from minus forty to plus eighty five degrees Celsius, supported by carefully engineered temperature coefficients for voltage, current and power.
Monocrystalline PERC half-cell generation: High purity monocrystalline silicon cells with PERC structure capture more sunlight by reflecting unabsorbed photons back through the cell, which increases internal absorption and improves conversion efficiency. The half cut format divides each cell into two sections, which reduces resistive losses and lowers operating current in each cell strip for better performance and higher reliability.
9 busbar and bypass diode current management: A dense 9 busbar layout collects current quickly from each cell and shortens the path that electrons travel, which reduces series resistance and enhances output under high irradiance. Three integrated bypass diodes in the junction box protect the module by limiting hot spot risk and allowing unaffected cell strings to keep generating when parts of the panel become shaded or soiled.
Rugged module design for stable lifetime yield: The 3.2 mm prismatic tempered glass with anti reflection structure increases light capture and protects the cells against impact, wind and snow loads during long term outdoor exposure. Anodized framing, IP68 junction box sealing and tested resistance to salt mist and ammonia environments support dependable operation near coasts, agricultural sites and industrial rooftops.
