Well people talk about Trina, jinko, sunpower, rec, qcells, lg neon, etc etc I rates GCL far ahead of the competition because its output electronics and device circuit ratios standout with the voltage rise calculation means even on the tiny light its reflects best sun absorption capacity with its high poly solar cell that's why it's world's largest poly crystalline solar modules. Its also their longetivity also to stand firm in rough weather, dangerous Storm<br /> Snow or amonia corrosion etc etc
