Yin et al have presented a PV T

Yin et al. [137] have presented a PV/T system with integrated heat storage using PCM as shown in Fig. 36. Water is directly heated by thermal GDC-0980 (RG7422) from the PV; it flows via a thermosiphon through the PCM, which will store the heat from the water for later applications. The water reached a temperature which was found to be useful in domestic applications. In ambient temperatures heat captured by the PCM prevented it entering the domestic dwelling and significantly reducing the cooling load.

The addition of PCM in PV/PCM systems has been shown to lower the operating temperature of PV by removing excess heat [138]. Currently, the heat is removed by the PCM substrate and stored, until a drop in ambient temperature results in the discharging of the PCM to the environment. Storing selective breeding available heat is being investigated currently [139].
