G. Install the Solar Panel

This step is to choose which rover you want to be for your project. Your kit comes with two different "solar panels," allowing you to swap the top of your rover. One is designed to look like the Yutu (Moon) rover, and the other is inspired by the Zhurong (Mars) rover.

1. Choose Your Solar Panel 
Decide whether you want your rover to be a lunar explorer (Yutu rover) or a Martian explorer (Zhurong rover) today.
​2. Place the Solar Panel on Top
The solar panel is designed to fit snugly on top of the rover's main body. Gently place your chosen solar panel on top of your your rover's main shell. It will cover the shell and complete the look. Make sure to align the the ultrasonic sensor extender square hole​ with your solar panel. If there is a solar panel sticker covering the square hole​, then make sure to cut a clean square hole through it to make sure that the  the ultrasonic sensor can be easily installed on top of the solar panel.
3. Attaching the Rover Hat 
To attach the hat, we will use the hook-and-loop tape. This will create a connection that is strong enough to hold the hat securely in place, but also allows you to remove it gently whenever you want to swap designs. You will need four pairs of the tape. Place one piece from each pair on the four corners of the rover's top shell. Then, stick the matching four pieces onto the corresponding spots on the inside of the rover hat. This ensures that when you press the hat down, it will lock into place.
