Day

The desired day is calculated.

Global radiation

The total global solar radiation on the current solar module.

Global radiation horizontal

A measure of the amount of radiation measured on a horizontal plate at the current location.

Solcells azimut

Is the angle of the solar cell and is defined as 0˚ at the north direction and 90˚ to the east, that is, can be compared with the dash. The angle is defined as the sun's rays hit the panel, ie the panel is directed straight towards the sun, the angle is offset 180˚.

Solar cell angle

Refers to the angle of the solar cell in relation to the horizontal plane, ie 0˚ when the solar cell lies flat on the ground.

Sun azimut

Is the angle of the sun and is defined as 0˚ at the north direction and 90˚ to the east, that is, can be compared with the weather dash.

Sun height

Refers to the angle of the sun in relation to the horizontal plane, ie 0˚ on the horizon and 90˚ when the sun is in zenith.
