One small point and well acknowledged on this issue is that we are starting with a product that only produces at 14-18% [up to19%] efficiencies to begin with.
A 5%loss is to an average of 16% efficiencies as 31.25% loss is to100% efficiency. Till PV modules hit 50-75% efficiency in conversion, I think we have a responsibility to our customers to give them every watt they are paying for. Weather it is in the DC side , AC side or both it is a cost of doing business. Our job, as I see It, is to keep that cost and loss to a minimum. Maybe the 600volt limit is too restrictive. I propose that we need from a NEC point of view, is to look at 800 or 900VDC limits VS the current 600VDC.
