Module Orientation, Tilt Angles, and Shading

IT IS NOT ENOUGH to collect data. The designer and installer must understand how each piece of information affects other design and installation decisions.

A thorough site visit to collect data is vital in order to design a highly effective photovoltaic system. Depending upon the project, an engineer or sales professional can conduct the site visit. It is the key to gathering information and cutting costs. You must consider site-specific information about shading, microclimate, and the customer’s intentions during the design phase.

Module orientation and tilt angles depend upon the information collected during the site visit. The site also influences the type of PV components and mounting ...
