HT-SAAE HT54-18X(ND)-F 450W vs HT-SAAE HT54-18X(ND)-F 460W

Q: Which panel is better: HT-SAAE HT54-18X(ND)-F 450W or HT-SAAE HT54-18X(ND)-F 460W?

According to our database: HT-SAAE HT54-18X(ND)-F 460W has higher module efficiency (23.00% vs 22.50%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of HT-SAAE HT54-18X(ND)-F 450W and HT-SAAE HT54-18X(ND)-F 460W?

HT-SAAE HT54-18X(ND)-F 450W has a module efficiency of 22.50%, while HT-SAAE HT54-18X(ND)-F 460W is 23.00%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does HT-SAAE HT54-18X(ND)-F 450W use vs HT-SAAE HT54-18X(ND)-F 460W?

HT-SAAE HT54-18X(ND)-F 450W uses TOPCon cells; HT-SAAE HT54-18X(ND)-F 460W uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.

Q: What is the warranty on HT-SAAE HT54-18X(ND)-F 450W and HT-SAAE HT54-18X(ND)-F 460W?

HT-SAAE HT54-18X(ND)-F 450W has a 30 years power warranty; HT-SAAE HT54-18X(ND)-F 460W has a 30 years power warranty. The power warranty guarantees a minimum percentage of rated output at the end of the warranty period (typically 80-87%). Product (materials) warranties are usually shorter.

Q: Are HT-SAAE HT54-18X(ND)-F 450W and HT-SAAE HT54-18X(ND)-F 460W bifacial panels?

Both HT-SAAE HT54-18X(ND)-F 450W and HT-SAAE HT54-18X(ND)-F 460W are bifacial - they capture reflected light from the ground, which can add 5-15% more annual energy on ground-mount or elevated rooftop installations with a light surface beneath.
