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 - 4,000 kWh usage per month
• System Specs
• 190 watt rated panel
• 112 panels
• 258 sq. ft amorphous silicon window (5
  conversion)
• 1182.4 kWh available per day for windows

20
Engineering Analysis

• Monthly Power Generated
