Corrigendum to “Design, manufacturing, and test of a high concentration ratio solar box cooker with multiple reflectors” [Sol. Energy 155 (2017) 781–792] (Solar Energy (2017) 155 (781–792), (S0038092X17305935), (10.1016/j.solener.2017.07.020))

The authors regret that the reported values of direct solar irradiance, DNI, are incorrect because a wrong calibration curve for the pyrheliometer data was used. In this corrigendum, the recalculated and thus correct values for DNI, as well as all solar radiation-dependent parameters, are provided as follows. Figures and tables with the corrected values are also reported. Page 787, section “5.1. Tests without load”, second paragraph, line 4: instead of “resulted equal to 0.39 °C/(W/m2)” it should be “resulted equal to 0.32 °C/(W/m2)”. Page 787, section “5.2. Water load tests”, first paragraph, line 2: instead of “The average direct normal irradiance was 802.70 W/m2” it should be “The average direct normal irradiance was 970.29 W/m2”. Page 787, section “5.3. Peanut oil load tests”, first paragraph, lines 3 and 4: instead of “The average ambient temperature and direct solar irradiance were, respectively, 30.80 °C and 677.13 W/m2” it should be “The average ambient temperature and direct solar irradiance were, respectively, 30.80 °C and 807.78 W/m2”. Page 790, section “5.4. Comparison with literature”, first paragraph, last lines: instead of “… being the average DNI higher than 700 W/m2” it should be “… being the average DNI higher than 800 W/m2”. The corrected Tables 2–6 are reported below. Values that differ from those in the original paper are indicated in bold. The corrected Figs. 7, 8, 9, 10, 11, 12 and 13 are shown below. For Figs. 7, 8 and 11, the only difference with respect to the figures in the original paper is the DNI indicated with the grey line. Fig. 9 differs from the one in the original paper only in the legend, in particular in the DNI values associated with the individual water tests. The standard cooking power, Ps, and the thermal efficiency, η, are shown in Figs. 10, 12 and 13, and were obtained using the corrected values of DNI measured during the corresponding tests. The authors would like to apologize for any inconvenience caused.
