Design Decisions: Energy•Battery Size Limiting Factor• Low Cost Design
•Quality Components• Durability
• 10 hrs of Sun Provides 3 Days of Energy Needs
Project Obstacles• Constructing Prototype Design• Flow Meter
Replacement
• Flow Switch to Manual Switch
• Fear of Making Mistakes• Decision Making
• Constructing Design
Water Testing
Water Testing
Electronic Testing• Fully Charged Battery
Powers Unit for 10.5 Hours
• Flow Switch to Manual Switch
• On a Slightly Hazy Day in Grand Rapids:• More Power Production Than
Power Consumption
• Additional Testing of Battery Required to Verify Long Term Functionality
