5. Revised Problem Statement & EMS Modeling Based on customer needs, the design team will have to tackle several issues. They will have to create a system that is able to generate enough power for a family of four using only solar energy. The system must be integrated into or replace the building envelope of the house. The design must be able to provide support of the structures that it replaced and withstand environmental elements.
