HT-SAAE HT72-18X-560W vs HT-SAAE HT72-18X-550W

Q: Which panel is better: HT-SAAE HT72-18X-560W or HT-SAAE HT72-18X-550W?

According to our database: HT-SAAE HT72-18X-560W has higher module efficiency (21.70% vs 21.30%). See the full spec comparison and 30-year energy simulation above for a complete picture.

Q: What is the efficiency of HT-SAAE HT72-18X-560W and HT-SAAE HT72-18X-550W?

HT-SAAE HT72-18X-560W has a module efficiency of 21.70%, while HT-SAAE HT72-18X-550W is 21.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does HT-SAAE HT72-18X-560W use vs HT-SAAE HT72-18X-550W?

HT-SAAE HT72-18X-560W uses TOPCon cells; HT-SAAE HT72-18X-550W uses PERC. 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 HT72-18X-560W and HT-SAAE HT72-18X-550W?

HT-SAAE HT72-18X-560W has a 25 years power warranty; HT-SAAE HT72-18X-550W has a 25 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.

Thirty years of production

Each panel's own declared degradation curve, at 1,200 kWh/kWp a year

Cell temperature

Same temp coeff. for both panels (-0.330 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
