This video is a hands-on visual demonstration of performing a RETScreen analysis for a Grid-Connected carport 15 to 20 kW in California. This tutorial will guide you step by step through the process of using RETScreen 4 to conduct a preliminary analysis for a residential/commercial scale system. It will describe in detail some key inputs. This demo will show the impact of using 20, 25 or 45 year life cycle. The analysis will cover a RETScreen 4 analysis type method 2 and will cover both a fixed array and tracker array. Note that this is one of 5 case studies covered in the Leonardo Academy course designed by the Clean Energy Institute of GPEKS, and that the full course contains extensive written documentation and a step by step document covering in greater details the material shown in the video.
