Eng..) - Asian Institute of Technology, 1987 Summary: A computer program in BASIC was developed to simulate the performance of stand -alone photovoltaic systems . The simulation was designed to ascertain that photovoltaic system reliability indexes, i.e. cumulative loss of load hours (LOLH) over one year, can be determined according to the meteorological conditions in Thailand, consumer consumption patterns, array size and battery size . The results of the simulation indicate that for a given load profile , there exist several combinations of array size and battery capacity which meet a prescribed system reliability . Economic analysis is introduced in order to allow for a trade-off between array size and battery capacity to meet a specified system reliability. The minimum cost f or meeting a prescribed system reliability is found a t the point where the marginal rate of substitution between array size and battery capacity is equal to the ratio of the array price to the battery The optimum degree of system reliability is thus determined by considering the cost of the system against the cost of running the backup power source, i.e. a diesel set, a given number of hours.
