... that is exposed to solar radiation can be called a solar collector. A solar FPC is made up of many parts; however, the main components of an FPC are a cover, combined absorber and riser, and insulation, as shown in Figure 2.
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 commercial cost of a solar collector is estimated at $811.76 dollars. To obtain the annualized cost of a solar collector network, Eq. (29) is used, which requires an annualization factor defined in Eq. (30). The equipment is assumed to have a lifespan of 20 years, and the annual interest rate is 8 %.
