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.

Engineering Analysis: Pennsylvania averages: 5 hours of sunlight 3, ,000 kWh usage per month System Specs: 190 watt rated panel 112 panels 258 sq. ft amorphous silicon window (5% conversion) kWh available per day for windows

Engineering Analysis: Monthly Power Generated: Roof Array – 3,192 kWh Windows – 2,117 kWh Total – 5,309 kWh

Concluding Remarks The design is fully able to sustain a family of four in Pennsylvania. The design is fully able to sustain a family of four in Pennsylvania. However, the house will take 40 years to break even. However, the house will take 40 years to break even.
