This question is part of the Super Big Solar Panel FAQ from Solar Mango, where expert answers to over 100 important questions on solar panels are provided.

 

The following are the parameters you should evaluate on:

  • Grade – Solar panels come in Grades A, B & C (Grade A being the highest quality)
  • Tier of the manufacturer – Organizations such as BNEF have come up with ranking of the solar panel manufacturer, classifying them into one of three Tiers (Tier 1 being the highest)
  • Efficiency – Solar panels have efficiencies ranging from 13%-24%
  • Performance under low light conditions – Some solar panels can generate higher amounts of electricity than other panels with the same Wp

  • Temperature coefficient – Solar panels with lower temperature coefficient (and higher temperature tolerance) lose less of their efficiency at higher temperatures
  • Warranties available – Solar panels come with performance warranties, which range from Standard to Linear
  • Presence of anti-PID features – Solar panels also come with features to tackle PID or Potential Induced Degradation, a characteristic that can cause significant harm to the panel within the first few years of installation.
