What it means on a roof

Thirty years of production
Each panel's own declared degradation curve, at 1,200 kWh/kWp a year
Same temp coeff. for both panels (-0.310 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

Questions about this pairing

Which panel is better: HT-SAAE HT54-18X(N)-465W or HT-SAAE HT54-18X(N)-470W?
According to our database: HT-SAAE HT54-18X(N)-470 W has higher module efficiency (23.50% vs 23.30%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of HT-SAAE HT54-18X(N)-465W and HT-SAAE HT54-18X(N)-470W?
HT-SAAE HT54-18X(N)-465 W has a module efficiency of 23.30%, while HT-SAAE HT54-18X(N)-470 W is 23.50%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does HT-SAAE HT54-18X(N)-465W use vs HT-SAAE HT54-18X(N)-470W?
HT-SAAE HT54-18X(N)-465 W uses TOPCon cells; HT-SAAE HT54-18X(N)-470 W uses TOPCon. Modern n-type technologies (TOPCon, HJT, BC) typically deliver higher efficiency and lower degradation compared to older PERC (p-type) cells.
What is the warranty on HT-SAAE HT54-18X(N)-465W and HT-SAAE HT54-18X(N)-470W?
HT-SAAE HT54-18X(N)-465 W has a 30 years power warranty; HT-SAAE HT54-18X(N)-470 W 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.

Every figure here is from the manufacturers' own datasheets - a dash means the value is not published, never an estimate. The thirty-year projection and the temperature scenarios are calculations from those figures, and each states its assumption above.
