Diffuse solar irradiation on a tilted surface with an isotropic model

## Information

This component computes the hemispherical diffuse irradiation on a tilted surface. The irradiation is composed of the diffuse horizontal solar irradiation and the irradiation that has been reflected by the ground. Both components are adjusted to take into account the tilt of the receiving surface.
