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 (-0.280 %/°C), so a warmer roof scales both curves by the same factor: the totals fall together and neither panel gains on the other.

According to our database: TCL Zhonghuan HSM-ND66-GK710 has higher module efficiency (22.90% vs 22.50%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of TCL Zhonghuan HSM-ND66-GK700 and TCL Zhonghuan HSM-ND66-GK710?
TCL Zhonghuan HSM-ND66-GK700 has a module efficiency of 22.50%, while TCL Zhonghuan HSM-ND66-GK710 is 22.90%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does TCL Zhonghuan HSM-ND66-GK700 use vs TCL Zhonghuan HSM-ND66-GK710?
TCL Zhonghuan HSM-ND66-GK700 uses N-type cells; TCL Zhonghuan HSM-ND66-GK710 uses N-type. 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 TCL Zhonghuan HSM-ND66-GK700 and TCL Zhonghuan HSM-ND66-GK710?
TCL Zhonghuan HSM-ND66-GK700 has a 30 years power warranty; TCL Zhonghuan HSM-ND66-GK710 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.
Are TCL Zhonghuan HSM-ND66-GK700 and TCL Zhonghuan HSM-ND66-GK710 bifacial panels?
Both TCL Zhonghuan HSM-ND66-GK700 and TCL Zhonghuan HSM-ND66-GK710 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.
