On the Use of the FSAV/FSC Characterization to Monitor and Guarantee the Solar Results of Combisystems

The FSC method enables to characterize combisystems performances thanks to a simple quadratic curve. This characteristic curve could be used to guarantee annual performances of a system and to control its proper functioning. This would raise interest and trust of users in such systems. This paper introduces how to use measured data with the FSC method in order to monitor the combisystem, estimate its annual performance during the system operation, compare the guaranteed and estimated annual performances and finally check the actual performance realized. The proposed algorithm is tested using many detailed yearly simulations of a combisystem.
