Questions about this pairing
Which panel is better: Horay Solar HS510TC-MHA-D or Longi Solar LR7-54HVH-475M?
According to our database: Longi Solar LR7-54HVH-475M has higher module efficiency (23.30% vs 23.10%); Longi Solar LR7-54HVH-475M tolerates heat better (temp coeff -0.260%/°C vs -0.280%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Horay Solar HS510TC-MHA-D and Longi Solar LR7-54HVH-475M?
Horay Solar HS510TC-MHA-D has a module efficiency of 23.10%, while Longi Solar LR7-54HVH-475M is 23.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Horay Solar HS510TC-MHA-D use vs Longi Solar LR7-54HVH-475M?
Horay Solar HS510TC-MHA-D uses TOPCon cells; Longi Solar LR7-54HVH-475M 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 HS510TC-MHA-D and Longi Solar LR7-54HVH-475M?
Horay Solar HS510TC-MHA-D has a 30 years power warranty; Longi Solar LR7-54HVH-475M 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 HS510TC-MHA-D and Longi Solar LR7-54HVH-475M bifacial panels?
Horay Solar HS510TC-MHA-D is bifacial (captures light from both faces); Longi Solar LR7-54HVH-475M is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
