Increased power and efficiency

PERC technology improves on an already high efficiency of 21.9 percent. The manufacturer created an efficient and highly durable model by adding a robust PID resistance and unique glass lamination on top. SIL-420-BG produces 420 W of power under standard test conditions.

Heat-resistant performance

This module makes the heat less dangerous since it has one of the lowest temperature coefficients in the market, losing just -0.377% of efficiency for every 1.8°F over 77°F.

Quality and reliability

SIL-420-BG receives multiple quality checks throughout the manufacturing process and is subject to stringent quality and reliability testing. The manufacturing facilities are highly automated, eliminating the risk of human error. Silfab is dedicated to quality, safety and reliability to ensure you get the very best.

Low degradation for increased lifespan

The amount of power output loss experienced by these panels during the first year of operation will not exceed 2%. The average yearly power drop from the second to the 30th year will not surpass 0.3%. After 30 years, the module will still produce more than 89.3% of its initial output.

A panel that can handle hail, wind, and snow

The 1.38" frame, built of black anodised aluminium and a layer of protective tempered glass, makes this module weather-resistant. Both the front and the back sides of the modules can withstand a 5400 Pa load.
