Avon PV Energy System

Project Name: AVON Solar PV Energy System

Department: Systems Application

Focus Area: Design, Engineering, Procurement and Installation

Product/Process: 16 kW PV SYSTEM

Prepared By: Geof Moser & Glenn Gu

A complete shading analysis was performed using computer aided design of the building occupied by Avon (a more extensive site analysis can be performed once the building is completed). Analysis shows that approximately 16 kW of installed PV can be placed on the roof structure of the building.

Extensive shading on the buildings roof has determined the design format and layout of the PV system. The 3D drawing provided in this document should give a better understanding of this situation.

*Please understand that as there is space for more solar modules to be placed on the roof, extensive shading on the PV modules would render them inefficient and cause excessive financial losses.
