What it means on a roof

Thirty years of production
Declared first-year losses, with 0.40% a year afterwards assumed for both panels, 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.

Questions about this pairing

Which panel is better: Horay Solar HS680TC-MHG-D or Horay Solar HS650TC-MHD-D?
According to our database: Horay Solar HS650TC-MHD-D has higher module efficiency (23.30% vs 21.90%). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Horay Solar HS680TC-MHG-D and Horay Solar HS650TC-MHD-D?
Horay Solar HS680TC-MHG-D has a module efficiency of 21.90%, while Horay Solar HS650TC-MHD-D is 23.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Horay Solar HS680TC-MHG-D use vs Horay Solar HS650TC-MHD-D?
Horay Solar HS680TC-MHG-D uses TOPCon cells; Horay Solar HS650TC-MHD-D 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 Horay Solar HS680TC-MHG-D and Horay Solar HS650TC-MHD-D?
Horay Solar HS680TC-MHG-D has a 30 years power warranty; Horay Solar HS650TC-MHD-D 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 Horay Solar HS680TC-MHG-D and Horay Solar HS650TC-MHD-D bifacial panels?
Both Horay Solar HS680TC-MHG-D and Horay Solar HS650TC-MHD-D 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.

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.
