Model SV120M.3.2-360 | Monocrystalline PERC Half‑Cut | 120 Half‑Cut Cells | Monofacial | 1000V System Voltage
The Selfa SV120M.3.2-360 monocrystalline half‑cut solar panel delivers 360W of reliable power with high efficiency for residential, commercial, and small industrial projects. This premium Selfa solar panel is engineered in Poland and designed for long term performance in demanding European climates. With a module efficiency of 19.7 percent, it supports compact rooftop systems where space is limited but energy yield must be maximized. Advanced PERC cell technology, a 9‑busbar layout, and half‑cut architecture help reduce resistive losses and improve real world output across the day. The module uses prismatic tempered glass with integrated anti‑reflection coating, improving light capture while assisting natural self‑cleaning when exposed to rain. Robust mechanical strength up to 3800 Pa wind load and 5400 Pa snow load allows confident use in harsh weather regions. This Selfa SV120M.3.2-360 solar panel also offers a positive power tolerance from 0 to plus 5 watts, ensuring that installed capacity is at least equal to the nameplate rating. For customers seeking a high quality European made module with proven durability, this 360W Selfa panel provides an excellent balance of performance, efficiency, and long term value.
High power density for limited roof space: The 360W output and 19.7 percent efficiency enable strong yields on compact residential and commercial rooftops.
Half‑cut cell design with 9‑busbar layout: Half‑cut monocrystalline PERC cells with 9 busbars are used to lower resistive losses, boost shade tolerance, and enhance real world performance.
Durable construction for tough weather: Robust mechanical strength up to 3800 Pa wind and 5400 Pa snow load provides reliable operation in harsh wind, snow, and hail conditions.
Optimized glass with anti‑reflection coating: Prismatic tempered glass with integrated anti‑reflection structure increases light capture while promoting self‑cleaning under rainfall.
Long term warranty protection: A 12 year product warranty and 25 year linear power warranty help secure predictable long term energy production and investment returns.
European quality from a Polish manufacturer: The module is produced by Selfa GE S.A. in Poland, supporting high quality standards, local service, and reliable supply for European projects.
The Selfa SV120M.3.2-360 solar panel converts sunlight into usable electricity through efficient monocrystalline PERC half‑cut cells. Sunlight strikes the prismatic tempered glass, which directs more light into the 120 half‑cut cells arranged across the module surface. Inside each cell, photons free electrons, creating direct current that is collected by the dense 9‑busbar grid. Half‑cut architecture divides the module into two electrically independent sections, reducing resistive losses and limiting power drop when partial shading occurs. The generated current flows through three bypass diodes in the IP68 junction box, which protect against local hot spots and maintain output under non uniform irradiance. From the junction box, power travels via 4 mm² cables and MC4 compatible connectors to the system inverter, where it is converted to alternating current suitable for homes and businesses. Stable performance is maintained across a wide ambient temperature range, helped by carefully controlled temperature coefficients for power, voltage, and current.
Monocrystalline PERC half‑cut cell operation: High quality monocrystalline PERC cells are used to capture sunlight with strong efficiency and robust reliability. The half‑cut configuration reduces current in each cell string, which lowers resistive losses and improves overall module efficiency under standard test conditions.
9‑busbar current collection and bypass diodes: A 9‑busbar metallization pattern collects current more evenly across each cell, shortening the path for electrons and reducing series resistance. Three bypass diodes in the IP68 junction box protect shaded cell strings, minimizing mismatch losses and limiting the risk of hot spots over the module lifetime.
Thermal behavior and real world performance: The module’s NOCT of 42 ± 2 degrees Celsius indicates stable operation in typical outdoor conditions with light wind. Carefully specified temperature coefficients for Pmax, Voc, and Isc ensure predictable performance as panel temperature rises on hot days, providing dependable output in diverse climates.
