Background System Design Efficiency Components Schematic Component Specifications Program Flow Cost Hurdles Future Adjustments Special Thanks

- Original Idea came from previous coworker - Had existing solar setup for his home - Asked me to build system for him - Lost contact - Every Engineer’s dream right?

Major Mechanical Parts - Solar Panel - Weatherproof Box - Worm Gear - 12V DC Drill - Roller Bearing Pillow Blocks - Turn Table - Aluminum Pipe & Plate

Vertical Single Axis Tracker (VSAT) - More effective at higher latitudes - Best benefit in winter time - Increase efficiency up to 30% - Why not dual axis? - Only increases efficiency by an additional 6%

Charge Controller H - Bridge Battery MicroP NAND IC Inverter IC 5v RegulatorLCD

Mechanical Encoder GPS Module LCD Screen

GPS – Global Sat EM-406a - 20 Channel, Built in antenna, TTL, 5V Baud Rate, Output Message – GGA, GSA, GSV - Altitude to 60,000 ft, Up to 15 ft Accuracy - Power Consumption (44mA) Continuous, (25mA) Trickle Microcontroller – Atmel Atmega 324P - 32KB of memory, 32 Programmable I/O Pins - Running at 1 MHz - Power Consumption – 0.4 mA Charge Controller - Automatic overcharge protection (14.4V) - Automatic discharge protection (12.4 on, 11.0 off) - Self Consumption < 10 mA Solar Panel - PMAX = 10 W, PMAX = 17 V, PMAX =.58 A Battery - 12 V, 9 Ahr Capacity, 5 yr float life

Mechanical Encoder - 5 V, 4 bit Hexadecimal - 16 Position, 22.5 deg LCD - 2x20 Character LCD - Temperature Range (- 40 to 185 degrees) - White LED Backlight - 5 V, 1.6 mA current - Parallel Connection H – Bridge - Voltage – Up to 48 V - 5 A Max peak current - 4 A RMS current - TTL Compatible

Mechanical Encoder 5.35 LCD Module23.09 GPS Module73.55 Turntable, Worm Gear Solar Panel Kit Aluminum Plate & Pillow Blocks V Drill19.99 Other Components – Donated by EE Department 0.00 Total

-Interfacing components to work properly -Burned out H – Bridge -Correct Coding to receive data -Aligning mechanical encoder -Appropriate size of worm gear

-Higher amp capacity H – Bridge -Different Design Possibilities -Possibly remove NAND & Inverter ICs -Develop code structure for better functionality -Add buttons for user friendly information gathering
