Finally, thank! man, that's what I was looking for. Ten 121 panels producing 1.3KW which seem like more than what they are rated for, it should have produced 1.21KW max, but if you look at the spec sheet I attached above it all makes sense.
What this shows is that yingly poly panel is being sold at its lab value but the sharp panel is being sold at its real world output value.
Thin film looking awesome at the moment. I'll try and find out if sharp is available here in Lahore.
