modelAbsSoltigua
Information
It solves the 1D radial energy balance around the Heat Collector Element of the Soltigua PTMx parabolic trough solar collector based on the Soltigua data sheet (see http://www.soltigua.com.)
The model allows to defocusing the collectors based on the Internal focusing signal. TRUE Defocusing = 0, FALSE Defocusing =1
