A smart tonneau cover for a pickup truck includes an input system that receives information concerning a route and the weather forecast for the route to a destination, the height of a cargo, a precipitation sensor, a wind sensor, and to determine the limits to the height, position, and orientation of the portions of a tonneau cover, which can include solar panels that can be moved to optimize power generation and minimize power consumption while protecting the cargo. The solar panels can be positioned when stationary, such as while parked, and repositioned as needed during transit to maintain an optimal power efficiency.
