HT-SAAE HT54-18X(N)-465W vs HT-SAAE HT54-18X(N)-515W

Q: Which panel is better: HT-SAAE HT54-18X(N)-465W or HT-SAAE HT54-18X(N)-515W?

According to our database: HT-SAAE HT54-18X(N)-465W has higher module efficiency (23.30% vs 23.20%). 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(N)-465W and HT-SAAE HT54-18X(N)-515W?

HT-SAAE HT54-18X(N)-465W has a module efficiency of 23.30%, while HT-SAAE HT54-18X(N)-515W is 23.20%. Higher efficiency means more electricity from the same roof area - useful when space is limited.

Q: What cell technology does HT-SAAE HT54-18X(N)-465W use vs HT-SAAE HT54-18X(N)-515W?

HT-SAAE HT54-18X(N)-465W uses TOPCon cells; HT-SAAE HT54-18X(N)-515W 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(N)-465W and HT-SAAE HT54-18X(N)-515W?

HT-SAAE HT54-18X(N)-465W has a 30 years power warranty; HT-SAAE HT54-18X(N)-515W 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.

What it means on a roof

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 (-0.310 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.
