Δ What is the difference between Tier 1 Solar Panel and not Tier 1 Solar Panel?
The main difference of the solar panel price is
between
Tier 1 Solar Panel
and
not
Tier 1 Solar Panel
.
If you order the
mainstream
solar panel --- cell size 166*166mm or 182mm*182mm (210*210mm will soon becoming popular), cell number 54pcs,60pcs, 72pcs, watt :365-670W), you can get
the lower price
, because our factory or others' have the stock. But we also can do the customized order, you can chose the cell battery IBC,TYPE P-perc or type N-I-TOPCON), mono or poly, Monofacial or Bifacial, size, watt and so on.
If you are interesting in stock panel, please contact me.
