Solar collectors are crucial components of a Solar Thermal Power plant (STP) which are required to be within a certain feasible range in order to operate and provide solar thermal resources and intermittent inputs. The closed-loop controller design for solar collectors enhances the lifespan of STP.
During solar collector field design, it is advisable to avoid combining series–parallel configurations within a single line. Optimal mass flow rates play a crucial role in solar collector performance. Operating with volumetric flows per collector above 4 l/min offers several advantages. It allows for increased thermal load and reduced unit costs.
The use of the design tool for parametric analysis coupled with economical calculations can provide optimisation of the solar collector construction. Heat loss from absorber through glazing to ambient environment for solar collectors with low-emissive absorber (emittance 0.05) is around 75 % of overall collector heat loss.
Based on the results obtained in this study, the following conclusions can be drawn: In solar collector network design, a fully parallel configuration is advantageous from a hydraulic perspective, but not from a thermal standpoint. Economic analysis indicates that a series configuration is more cost-effective for thermal energy production.
