Abstract: A clamping device for a solar module has or forms at least a first receiving portion for receiving an edge portion of the solar module. The first receiving portion has at least a first side wall portion and an additional side wall portion for constructing a receiving region. The first receiving portion is constructed in an integral manner. The elasticity modulus of the first receiving portion is greater than the elasticity modulus of rubber. There is also disclosed a method for assembling a solar module.
