You are correct, but just as a point out for people, wind I am not sure, but Photovoltaics I am positive are accumulate per panel, or per unit for newer panels redesigned as solar roofing materials, intead of panels on roofing materials, utilize inverters, which are some of the most lossy circuit designs for power conversion right now.

Until inverters are made to be more efficient, this will always be a huge bottleneck for dynamic energy input and output for the solar industry, and should be considered as apart of the losses for a solar unit.
