2.1 Optical Performance of Solar Collector Fields. The optical performance of solar collector fields has to consider several aspects. In line focussing systems the individual collectors are arranged in a long row connected through the heat transfer fluid piping. First of all, there is an interaction of individual collector rows by mutual shading.
Transporting electricity over long distances would also become much easier, which is particularly useful for renewable energy applications – and some have proposed giant superconducting cables ...
