Questions about this pairing
Which panel is better: Exiom EX555MB(144)182 or Exiom EX600TC-144HC182BF?
According to our database: Exiom EX600TC-144HC182BF has higher module efficiency (23.20% vs 21.50%); Exiom EX600TC-144HC182BF tolerates heat better (temp coeff -0.280%/°C vs -0.350%/°C). See the full spec comparison and 30-year energy simulation above for a complete picture.
What is the efficiency of Exiom EX555MB(144)182 and Exiom EX600TC-144HC182BF?
Exiom EX555MB(144)182 has a module efficiency of 21.50%, while Exiom EX600TC-144HC182BF is 23.20%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Exiom EX555MB(144)182 use vs Exiom EX600TC-144HC182BF?
Exiom EX555MB(144)182 uses PERC cells; Exiom EX600TC-144HC182BF uses TOPCon. 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 Exiom EX555MB(144)182 and Exiom EX600TC-144HC182BF?
Exiom EX555MB(144)182 has a 30 years power warranty; Exiom EX600TC-144HC182BF 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 Exiom EX555MB(144)182 and Exiom EX600TC-144HC182BF bifacial panels?
Exiom EX600TC-144HC182BF is bifacial (captures light from both faces); Exiom EX555MB(144)182 is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
