Photovoltaics module

Photovoltaics modules, also known as solar panels or PV modules, are the core components of any photovoltaic system that convert sunlight directly into electrical energy through the photovoltaic effect. These modules are typically composed of multiple solar cells made from semiconductor materials such as monocrystalline or polycrystalline silicon, encapsulated in a protective laminate with a tempered glass front and a polymer backsheet. Key technical specifications include peak power output (Wp), efficiency rating (%), open-circuit voltage (Voc), short-circuit current (Isc), maximum power voltage (Vmp), and maximum power current (Imp). Modules are available in various configurations, including 60-cell, 72-cell, and 144-cell formats, with standard operating voltages ranging from 12V to 48V and higher for utility-scale installations. The frame is usually made of anodized aluminum, and the junction box houses bypass diodes to minimize power loss under partial shading conditions. Modules are rated for durability with IP67 or IP68 junction boxes and are tested for resistance to hail, wind, and snow loads according to IEC 61215 and IEC 61730 standards.

Photovoltaics modules are deployed across a wide range of sectors, from residential rooftop installations to commercial and industrial ground-mounted solar farms. In residential applications, they are typically integrated into building-mounted structures or carports, feeding energy into grid-tied inverters or battery storage systems. Commercial and industrial installations often involve large-scale arrays on flat roofs or open land, powering factories, warehouses, and office buildings. Utility-scale solar plants use thousands of modules arranged in rows with tracking systems to maximize energy yield. Off-grid applications include remote telecommunications towers, water pumping stations, and rural electrification projects. Modules are also used in building-integrated photovoltaics (BIPV), such as solar roof tiles and facades, and in agrivoltaics where crops are grown beneath elevated panels.

Within our catalog, the main subcategories include monocrystalline modules, polycrystalline modules, and bifacial modules. Key article codes are structured as follows: for monocrystalline modules, the code format is PV-MONO-XXXW, where XXX represents the peak power in watts (e.g., PV-MONO-400W for a 400W module). For polycrystalline modules, the format is PV-POLY-XXXW (e.g., PV-POLY-300W). Bifacial modules use the code PV-BIFI-XXXW (e.g., PV-BIFI-450W). Additionally, we offer half-cut cell modules (PV-HALF-XXXW) and shingled modules (PV-SHIN-XXXW). These modules come with standard certifications and are available in various voltage classes, including 1000V and 1500V DC systems. Each module includes a datasheet with I-V curves, temperature coefficients, and mechanical specifications.
