Questions about this pairing
Which panel is better: Exiom EX605TC-144HC182BF or Exiom EX550MB-144BF?
According to our database: Exiom EX605TC-144HC182BF has higher module efficiency (23.40% vs 21.30%); Exiom EX605TC-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 EX605TC-144HC182BF and Exiom EX550MB-144BF?
Exiom EX605TC-144HC182BF has a module efficiency of 23.40%, while Exiom EX550MB-144BF is 21.30%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Exiom EX605TC-144HC182BF use vs Exiom EX550MB-144BF?
Exiom EX605TC-144HC182BF uses TOPCon cells; Exiom EX550MB-144BF uses PERC. 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 EX605TC-144HC182BF and Exiom EX550MB-144BF?
Exiom EX605TC-144HC182BF has a 30 years power warranty; Exiom EX550MB-144BF 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 EX605TC-144HC182BF and Exiom EX550MB-144BF bifacial panels?
Both Exiom EX605TC-144HC182BF and Exiom EX550MB-144BF 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.
