Energy costs produced in solar plants provided with small buried thermal storage systems capable of supplying the domestic hot water and a fraction of the winter heating requirements, have been evaluated. The thermal analysis was carried out in conditions of climatic variability, generating the insolation sequences by a stochastic prediction model and simulating the plant with an experimentally tested code. The solar fraction that makes the unitary cost of energy produced minimal was determined with the life cycle cost method.

Abstract
Energy costs produced in solar plants provided with small buried thermal storage systems capable of supplying the domestic hot water and a fraction of the winter heating requirements, have been evaluated. The thermal analysis was carried out in conditions of climatic variability, generating the insolation sequences by a stochastic prediction model and simulating the plant with an experimentally tested code. The solar fraction that makes the unitary cost of energy produced minimal was determined with the life cycle cost method. The results were compared with those obtained by using climatic data relative to the historic year.File in questo prodotto:
