The calculation of the temperature and concentration dependence of the quadrupolar-glass (QG) order parameter of solid hydrogen is presented. Starting from the microscopic Hamiltonian describing the electric quadrupole-quadrupole interaction, the effective Hamiltonian containing only commuting operators related to the components of the tensor of molecular quadrupolar momentum has been obtained. By means of this Hamiltonian the equation for the average QG order parameter has been formulated within the replica theory. The calculated tmeperature and concentration dependence of the order parameter is compared with the experimental data obtained by Meyer and Washburn.
