The mathematical model of solar collector consists of external energy balance of absorber (heat transfer from absorber surface to ambient environment) and internal energy balance of absorber (heat transfer from absorber surface into heat transfer fluid).
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.
Computer modeling of solar thermal collectors is a principle approach for testing of new construction concepts and improvements in the development and design stage for developers and manufacturers. Virtual prototyping of solar collectors can save the investments into number of prototypes and foresee the collector performance in advance.
