What’s so great about crystalline? More power that’s what! lol
This is a test I have been wanting to try for a long time. And I only had a brief chance to do it before these two 120 watt monocrystilline panels are to be installed.
The theory being: Although amorphous (thin film) panels DO perform better under low light for a given WATTAGE, if we instead compare a mono vs a thin film of approximately the same SIZE we will find that the mono does just as well. Or will we?
