Which panel is better: Boviet Solar BVM7612M-580-H-HC or Boviet Solar BVM7612M-540-H-HC?
According to our database: Boviet Solar BVM7612M-580-H-HC has higher module efficiency (22.45% vs 20.80%); Boviet Solar BVM7612M-580-H-HC tolerates heat better (temp coeff -0.300%/°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 Boviet Solar BVM7612M-580-H-HC and Boviet Solar BVM7612M-540-H-HC?
Boviet Solar BVM7612M-580-H-HC has a module efficiency of 22.45%, while Boviet Solar BVM7612M-540-H-HC is 20.80%. Higher efficiency means more electricity from the same roof area - useful when space is limited.
What cell technology does Boviet Solar BVM7612M-580-H-HC use vs Boviet Solar BVM7612M-540-H-HC?
Boviet Solar BVM7612M-580-H-HC uses TOPCon cells; Boviet Solar BVM7612M-540-H-HC 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 Boviet Solar BVM7612M-580-H-HC and Boviet Solar BVM7612M-540-H-HC?
Boviet Solar BVM7612M-580-H-HC has a 30 years power warranty; Boviet Solar BVM7612M-540-H-HC has a 25 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 Boviet Solar BVM7612M-580-H-HC and Boviet Solar BVM7612M-540-H-HC bifacial panels?
Boviet Solar BVM7612M-580-H-HC is bifacial (captures light from both faces); Boviet Solar BVM7612M-540-H-HC is monofacial. Bifacial panels work best on ground mounts or raised structures with a light-coloured surface underneath.
