Description

Received the new solar panel model. And Finch's overall interior is undergoing changes. For example, the design of the aluminum track has been updated. Therefore, a new design was needed for the installation of the solar panels and the corresponding side panels.A detailed description of the scope and motivation for this project, as well as any relevant resources

Tasks

• [ ] Confirm how the side panels and solar panels are connected.

Mounting - March 11

• How to mount solar panels to rails from the back

Measurements - March 4

• Solar panels 83 mm wide
• FINCH 340
• .5 mm from one end of the rail/foot to the other
• 36 mm from rail foot to top of tuna can
  • Currently 34 mm
  • 42.5 mm
  • Put the 10m in 6.5 mm
• Antenna is 8.5 mm tall
• Foot is 6.5 mm tall
• FINCH is currently 355.5 mm
  • Make rails 9.5mm shorter
  • Total inside length loss in z direction = 15.5 mm
  • Total rail length loss in z direction = 9.5 mm
  • If we add stackup bracket (5.5mm)and make transceiver flush with ADCS 10m (-5mm)
  • 10 mm of space is lost……
• Solar panels would have 342.5 - 9.5 = 333 mm
  • 40 mm x 8 = 320 mm
    • 13 mm extra
    • Minus the 5mm = 8 mm
  • 338.5 mm currently
  • distance between each panel?
• 83 mm width
  • 80 mm
  • 3mm to fit a hole on the side
• One possible solution
  • Make the rails 1mm thinner
  • Put the solar panels in the rails instead of on the outside
  • Screw in the solar panels to the rails from the outside
  • Either put all bracket mounting holes on another side, or make board longer inside and add holes to pcb to allow brackets to screw into rails
