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

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
