The optimisation of PV/T flat-plate water collector groups depending on the variable values of mass flow rate, tube diameter, tube spacing and number of collectors was made based on exergy efficiency. Two different hydronic configurations, namely, series and series-parallel connection arrangements were investigated. An analytical model was developed to obtain exergy efficiencies. The results showed that when all other parameters were kept constant, the total exergy gain for any operating condition was higher at the series connected collector arrangement than at the series-parallel one.
