All of the pentominos have a different heigt, that corresponds with their position in the alphabet; F is the lowest, Z the highest pentomino. The clues outside the grid tell how many pentominos can be seen from that side. A pentomino is visible when no higher pentomino is in front of it.
Solution code: Row 11, followed by column 5. For every cell the letter of the pentomino and '-' for an empty cell.

@sandmoppe: that is a good idea. I didn't realize puzzlers would write the pento-letters in the grid, but now that is possible with the grey cells. Thanks for the hint!

New image uploaded; grey cells instead of black ones.

Die schwarzen Kästchen haben mich immer wieder in die Irre geführt. Vielleicht wäre es besser, sie grau zu halten. Dann kann man den Pentomino-Buchstaben hineinschreiben und glaubt nicht immer, dass es sich um ein Leerfeld handelt.
