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.

Questions about this pairing

Which panel is better: Horay Solar HS460TC-MHB or Horay Solar HS460TC-MHB-D?
According to our database: both panels are closely matched on key specs - the decision often comes down to price and local availability. See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Horay Solar HS460TC-MHB and Horay Solar HS460TC-MHB-D?
Horay Solar HS460TC-MHB has a module efficiency of 22.60%, while Horay Solar HS460TC-MHB-D is 22.60%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Horay Solar HS460TC-MHB use vs Horay Solar HS460TC-MHB-D?
Horay Solar HS460TC-MHB uses N-type cells; Horay Solar HS460TC-MHB-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 HS460TC-MHB and Horay Solar HS460TC-MHB-D?
Horay Solar HS460TC-MHB has a 30 years power warranty; Horay Solar HS460TC-MHB-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 HS460TC-MHB and Horay Solar HS460TC-MHB-D bifacial panels?
Horay Solar HS460TC-MHB-D is bifacial (captures light from both faces); Horay Solar HS460TC-MHB is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.

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.
