There is a certain relationship between the wattage and weight of solar panels, but this relationship depends on various factors, such as the material, size, design, and so on of the solar panel.

Here are some common wattage and weight data for solar panels for reference:

Polycrystalline silicon solar panel: A polycrystalline silicon solar panel with a wattage of 250W, weighing approximately 18-23kg.

Monocrystal silicon solar panel: A single crystal silicon solar panel with a wattage of 300W, weighing approximately 19-24kg.

It should be noted that the higher the wattage of a solar panel, the larger its size and weight, but at the same time, it generates more electrical energy.

Moreover, in practical use, the weight of solar panels is also influenced by various factors such as installation method, bracket material, angle, and orientation.

Therefore, when selecting solar panels, it is necessary to comprehensively consider factors such as performance, size, weight, installation requirements, and usage scenarios to select the most suitable solar panel.
