Solar Energy Estimations

Concepts

Radiation from direct sunlight.

Radiation from reflected sunlight from either the ground or the sky.

Total radiation on a surface including direct and diffuse sources.

This is the insolation on a surface parallel to the ground.

This is the insolation on a vertical surface, like a window.

For a window, this is the radiation striking the outside surface.

For a window, this is the radiation that is transmitted by the window into the interior space without being reflected or absorbed.

Insolation is usually reported in power or energy per area.
