Next Generation N-Type Cell Technology

Silfab Prime NTC cells surpass the performance and reliability limitations encountered in standard solar cells, resulting in enhanced power output, higher efficiency in low light conditions, consistent performance in high temperatures, improved shade tolerance, and reduced degradation rates throughout the lifetime of the panel. 

Standard Solar Cell technology relies on a p-type wafer with openings in the rear passivation for charge collection (charge carriers trying to find a small hole), causing reduced passivation, limiting efficiency and overall power output. 

Silfab Prime NTC Solar Cell technology uses an n-type wafer with a rear NTC passivation layer enabling better charge carrier collection while reducing recombination leading to improved efficiency

MORE POWER MORE PRODUCTION 

IMPROVED EFFICIENCY 

Silfab Prime NTC boast significantly higher efficiency levels than standard conventional solar panels through better LCOE (levelized cost of electricity), requiring fewer solar panels and delivering unmatched efficiency and generating more power over the solar system’s life. 

Made to withstand the test of time

REDUCED DEGRADATION RATE & LID 

Silfab Prime NTC presents lower degradation in comparison to industry standard panels annually, attributed to their heightened resilience against diverse stressors, encompassing light exposure, mechanical loads, and thermal fluctuations, etc. 

ENHANCED DURABILITY & SUPERIOR WARRANTY

Silfab Prime NTC features a unique passivation layer that protects against moisture, UV, temperature, and other environmental factors, ensuring prolonged lifespan. Tested by third-party renewable energy test center RETC and PVEL for top performance ensures all Silfab Solar panels are tier-one quality. 

Reliable for decades

LOWER OPERATING TEMPERATURE & HIGHER TEMPERATURE TOLERANCE 

Silfab Prime NTC maintains higher efficiency levels as temperatures rise, withstanding higher operating temperatures and providing more consistent performance and maximum power output in all weather conditions. 

IMPROVED LOW LIGHT PERFORMANCE 

Silfab Prime NTC has better long-term performance in low-light conditions, (cloudy days or early mornings/late afternoons), due to enhanced sensitivity to diffused light, ensuring continuous energy generation even when sunlight is not at its peak.
