- Frame Design
- The frame must move on two axes
- First Axis controlled by the heliostat to provide daily tracking of the sun
- Second Axis controlled manually for annual positioning toward sun

- Solar Panels
- Can we use the solar panels instead of photo resistors.
- Charge battery by solar panels.
- Power Draw Problem
- Further testing should be performed to ensure a full day of power
- Test the heliostat running indoors and record the power life
- Checking Voltage Readings over course of a day
