...-up solar field using the CL strategy allows us both operational autonomy and significant energy savings. Solar loop thermal and optical powers gained and lost are plotted for the typical days considered; we observe that maximum thermal efficiency of 66.53% is achieved at 2.27 p.m. for the summer day...

..., the surrounding thermal losses decrease from 2505 W h to 2286 W h as the emissivity decreases from 0.74 to 0.14. This drop in energy losses (−219 W h) is recovered by the water of the tank (1207–1426 W h) and serves to rise its temperature (41–46 °C) and the thermal efficiency (23–28%). We can deduce...
