A total of 13 solar collector models were analyzed, as shown in Fig. 2 rstly, the appropriate amount of PCM characterized by the PCM height was determined according to the input of 8-h solar radiation intensity of 800 W/m 2 [30]. Fig. 2 (a) presents Models 1–4 with different PCM heights (h P = 20, 40, 60, and 80 mm) without copper fins.
For example, a 1% rel. increase in efficiency of the bi-HSAT system located in Boulder, Colorado results in a 1.1% increase in annual energy yield. More-accurate measurement capabilities can affect future terawatt deployments on the several gigawatt scale, therefore changing system cost, material consumption, and land use.
