    • Do not use a prying motion when removing the solar panel as this might break it.

    • Insert the flat end of the spudger between the solar panel and the black cover at the corner where the red wire connects.

    • Carefully slide the spudger all the way underneath the solar panel until it detaches from the tape.

    • If the solar panel does not completely disconnect once you have fully inserted the spudger, you can gently pull or pry it the rest of the way off.
