What is the role of conduction heat transfer in solar collectors?

Conduction heat transfer occurs within the solar collector itself, as heat is transferred from the absorber plate to the working fluid (such as water or air). Conduction heat transfer is critical in solar collectors, as it determines the rate at which heat is transferred from the absorber plate to the working fluid. Materials with high thermal conductivity, such as copper or aluminum, are often used in solar collectors to enhance conduction heat transfer.
