modelSolarThermalEfficiency
Calculates the efficiency of a solar thermal collector
Information
Overview
Model for the efficiency of a solar thermal collector. Inputs are outdoor air temperature, fluid temperature and solar irradiation. Based on these values and the collector properties from database, this model calculates the heat flow to the fluid circuit. We assume that the fluid temperature is equal to the collector temperature.

Limit eta to 0 and eta_zero.
Add correct units.
Avoid dividing by G=0. -
