Aim of this work is the design of a programmable electronic system for monitoring the
environmental parameters and managing the electrical functions of a thermo-solar plant. The
designed control unit detects data from temperature and light sensors, processes acquired
information and commands external equipments (pumps, electric valves and power supplies) in
order to optimize plant performances and maximize efficiency and energy savings. Recently several
researches, in the field of solar thermal energy production, have demonstrated that nanofluid-based
solar collectors present higher conversion efficiency. In this context, the designed control unit can
be used to detect their operation parameters in order to compare the performances of nanofluidbased
solar collector with those of traditional one. The electronic experimental setup is capable to
monitor, at the same time, the two different types of solar collector in similar environmental
conditions and to show on touch screen display the detected performances. In order to have
reference data, experimental measurements have been carried out by using traditional water and
Al2O3–based nanofluid thermo solar collectors. The obtained experimental data showed the benefit
in terms of efficiency in the use of nanofluid as heat transfer fluid in such a system.
