This work presents predictions on the amplitudes of solar g-modes. It is based on the assumption that convective overshoot into the convectively stable interior generates gravity waves. Based on this assumption it is possible to estimate values for the amplitude of the g-modes below the solar convection zone. Numerical simulations, giving the transmission of gravity waves through the convection zone have been carried out for 5 different frequencies and horizontal extents equivalent to l-values approximately in the range 6-18. The horizontal velocity amplitude of solar g-modes near the solar surface is estimated to be in the range 0.01-5mm/s. The largest value assumes that all the available energy from the excitation goes into a single mode. Using assumptions on the ratio between intensity and velocity oscillations the amplitude in intensity of a l=6 mode is estimated to be <=5x10^-7^.
