On the Simulation of a Mono-Actuator Bi-Axial Azimuth PV System

Abstract

The current trends in solar tracking systems and their appropriate tracking programs aim to capture the most of the solar radiation using simple devices. These have to be done considering the specific local and climatic configuration of the implementation area. In order to accomplish these conditions, the present paper proposes a non-adjustable mono-actuator, bi-axial azimuth mechanism, starting from a previous adjustable proposal, and determines its optimised length dimensions for Brasov’s climatic conditions, by means of numerical simulations. Consequently, the received direct solar radiation amount is estimated considering the clouds’ presence in the sky during each month by means of a specific factor referred to as the Clouds’ Crossing Factor.
