Overview
Site Overview is where you can find the project information after setting up your project in Site Configuration. Based on the latitude and longitude, local design data can be pulled, including wind speed, seismic, and snow. It is also where you can choose modules and inverters which will be in the project. You can also set which weather source file to use for your project.
