Designing integrated PV facility with dual-axis solar tracking system mounted on the south building face

Abstract

This paper provides rationales for effective application of a solar tracking system at the latitude of Chelyabinsk. Efficiency of the PV facility can be improved by 32% with a single-axis tracking system. Expected power increase of the dual-axis tracking system is 40%. The paper presents one of the most accurate algorithms for solar tracking-NREL SPA. Based on the tracking algorithm, equations of the sun diagram are developed for the Chelyabinsk latitude. In addition, the design of the integrated wall-mounted PV facility are described. The proposed design allows cost reduction of the solar tracking system due to decreased number of linear actuators.
