Sunergy Back Contact 425W Monofacial Solar Panel
Model Sunergy Back Contact 425 | Back Contact | 120 Half-Cell | Monofacial | 1000V System Voltage
Product Overview
The Sunergy Back Contact 425W monofacial solar panel is engineered for reliable on roof performance and long term energy yields. This high efficiency panel uses advanced back contact cell technology to deliver a power range from 415 to 425 watts, ideal for residential and small commercial solar installations. The solar panel design keeps all busbars on the rear side of the cell, which helps reduce shading losses and improves visible surface area on the front glass. As a result, more sunlight is captured and converted into usable electricity across the module surface. With panel efficiency between 21.08 and 21.59 percent, this module supports compact system layouts where roof space is limited. The 21 kilogram weight offers a balance between robust construction and easier handling for installers on site. This Sunergy solar panel suits customers seeking dependable output, neat aesthetics, and a future ready home energy upgrade.
Key Benefits
High power density for tight roof spaces: The 415 to 425 watt output allows more energy from fewer panels. This helps homeowners maximise generation on smaller or shaded roofs without compromising overall system performance.
Advanced back contact cell architecture: Back contact technology removes busbars from the front of the cells, which reduces shading and visual clutter. This design can enhance light capture while delivering a clean, uniform panel appearance on the roof.
Premium module efficiency up to 21.59%: Module efficiency of 21.08 to 21.59 percent supports higher energy production per square meter. This efficiency range helps reduce balance of system costs by requiring fewer mounting structures and electrical components.
Balanced 21 kg weight for easier handling: A panel weight of 21 kilograms offers solid durability with practical transport and installation. Installers can move and position the module more safely, which supports faster project completion on site.
Flexible choice for homes and small businesses: The power class and technology make this module suitable for pitched roofs, flat roofs, and retrofit projects. System designers can match it with modern inverters and mounting systems for many on grid configurations.
How It Works
This Sunergy back contact solar panel turns sunlight into direct current electricity through interconnected photovoltaic cells. Each cell uses a semiconductor junction that creates an electric field when photons strike the surface. The back contact layout keeps the electrical connections on the rear, which leaves the front glass mainly devoted to light absorption. When sunlight hits the cell, electrons are excited and move across the internal electric field, generating current that flows through the rear conductors. Multiple cells are wired together inside the laminate to achieve the 415 to 425 watt power range at standard test conditions. The direct current produced can be routed to an inverter, where it is converted into alternating current for household appliances or grid export. This process repeats every day as long as sufficient solar irradiance reaches the panel surface. In this way the module supports lower electricity bills and a reduction in grid dependence.
Back contact cell current collection: In a back contact design, metallic conductors are placed behind each cell rather than on the surface. This configuration keeps more active area exposed to sunlight and minimises optical losses from front busbars. The result is improved current collection and a cleaner visual finish on the installation.
Module interconnection and power output: Individual cells are joined in series strings to build the desired voltage and current. The combined string layout is optimised to achieve the 415 to 425 watt nominal power rating. Laminated glass, encapsulant, and backsheet protect the cells so stable output is delivered over many years of outdoor exposure.
Integration with inverters and home systems: The direct current from the panel is fed through DC cabling to a compatible inverter or microinverter. The inverter converts the energy into usable alternating current that can power loads or be exported. Monitoring systems can then track production, supporting smarter energy use throughout the property.
