Energy performance results of 240 mw x year of spanish large-scale pv plants

Resumen

ABSTRACT: large-scale Spanish photovoltaic plants is presented. 20 installations, totalling more than 90 MW, are analysed for a period of up to 4 years. We suggest a procedure to assure the consistency of the data coming from the field and a method of calculating the energy availability rate of the installations, both of them in a way that is independent of the operator of the plant. The operational results are final yields of more than 1,500 kWh/kW for static installations and more than 2,100 kWh/kW for a 2-axis tracking configuration; average performance ratios of 0.8 and energy availabilities of more than 99.5%, with no significant differences between static and tracking systems. Because of the large size and wide location distribution of this sample, we consider these results representative of the performance of large scale PV plants in Spain.
