Validation of a simulation program for photovoltaic systems

(Received 2 August 1991, accepted 22 August 1991)

Abstract
A program simulating the long term behaviour of PV system is validated by means measurements done for about two years on a stand alone system of 760 W , with a storage battery of 280 Ah. The simulation is carried on with measured solar radiation as well as with data generated by stochastic technique. The simulated and measured solar total covered load are compared. For both radiation kinds the simulation fits the experimpntal data in a satisfying way. The effect on the storage of the autocorrelated nature of daily radiation sequences is accounted for using a generation technique which reproduces well the short term fluctuations.
