Protection from the sun

[Calendyr]

What do you guys use to protect the car from the sun for places where there is no shade?

To start with I will be using a car to go to clients places so I can't use something huge. Also I will be working alone so I can't use something that needs 2 guys to setup and move.

Anyone in my situation who found a good way to deal with this?

pop up gazebo, maybe even 2 3x3m next to each other as they aren't that big to take along
