New light curves in two wavelengths (B and V) of eleven W UMa- type systems, obtained at Kryonerion Observatory in Greece, are presented. The light curves of these systems are analysed by using Frequency Domain techniques and new geometric and photometric elements are given. These elements are combined with the available spectroscopic data of the systems and new absolute elements are derived. Using the latter elements the evolutionary status of these systems is considered on the basis of mass-radius and mass-luminosity diagrams, and the results are compared with previous studies, where the physical parameters of these systems are based on photometric elements derived by other methods.
