The curtain wall includes mullion profiles, transom profiles and one or more panels, where the mullion profiles extend vertically, where the transom profiles each are attached to two mullion profiles and extend horizontally, where the mullion profiles are provided with a groove on each side for receiving the side edge of a panel. The grooves have an access opening, where the access opening has a first fixed dimension or width in a horizontal direction, where the transom profiles have a second dimension in a horizontal direction and at right angles to the profile direction of the transom profiles, where the second dimension is larger than the first dimension, where the transom profiles have a third dimension in a non-horizontal direction at right angles to the profile direction, where the third dimension is smaller than the first dimension.

A glazing and condensation system for roof panels comprises mullions and purlins. Roof panels are disposed above the mullion. A section of double-sided tape is disposed between a first roof panel and the mullion. A section of double-sided tape is disposed between a second roof panel and the mullion. The roof panels can be solar roof panels and/or glass roof panels. A first condensation collection channel is arranged beneath the first roof panel. A second condensation collection channel is arranged beneath the second roof panel. A third condensation collection channel is arranged perpendicular to the mullion, beneath the first roof panel, and above the first condensation collection channel. A fourth condensation collection channel is arranged perpendicular to the mullion, beneath the second roof panel, and above the second condensation collection channel. The condensation collection channels collect condensation and/or drippage from roof panels, and cause condensation and/or drippage to be channeled away from a solar cover. A wire casing includes wires that are connected to solar roof panels.
