Application of customized PV solar system layout in complex mountainous terrain characterized as multi slope faces

Based on the comparative analysis between the practical operational data and the theoretical calculation results in feasibility study stage of a PV solar station, the applicability of customized PV solar system design in complex terrain with multi slope faces was checked and tested. It was showed that the practical output was consistent with the feasibility study results considering the fact of solar poorer year and equipment maintenance and failures. By comparing and analyzing the output of different power units, it was found that the output difference was caused by the different proportion of east-west consequent PV arrays. It revealed that there is a strong positive correlation between the practical output of power units and the proportion of east-west consequent PV arrays.
