Industry-Leading Efficiency of up to 20.8%

Premium quality materials and strict quality control management allow Silfab panels to show an efficiency of up to 20.8% under test conditions. Reduced thermal stresses and increased current flow paths contribute to an even greater solar power harvest.

Back Contact Technology

Silfab is one of the first to introduce next generation Back Contact technology. In a Silfab 370W solar panel, all electrical contacts are placed at the back of a cell. It creates lots of additional space on the front of the module to capture more sunlight.

Quality and Reliability

The quality of each Silfab BC Series 370W panel is under meticulous control throughout the manufacturing process. Silfab panels are designed and manufactured to meet Buy American Act Compliance.

Enhanced Frame Design

The module’s aluminium light-weight frame is compatible with different racking. It is also extremely durable, being able to withstand a heavy snow load up to 5400 Pa and wind loads up to 4000 Pa.

25 Year Product and 30 Year Performance Warranty

Silfab BC Series 370W comes with an industry leading 25-year product workmanship and 30-year performance warranty.
