    A Tier 1 Panel means it is a Grade A solar cell and will have its performance claims backed-up by a 3rd party

    If it’s a Tier1 panel look at the data sheet and if it is backed by a 3rd party. i.e. Chubb or Zurich on its performance, then it is a genuine tier one panel.

    Tier 1 solar panels are all good in low light and have to be certified for salt and ammonia that is normal with a Grade A panel.
