HIGHER POWER PRODUCTION = SECURE YIELDS

LUXOR Solarmodul Produktion

Bifacial solar modules use both direct radiation on the front and indirect light on the back to generate electricity. A glass pane on the rear side of the module enables both unused light that passes through the module and reflected light from the surroundings to be captured by the cells on the back.

Factors such as the so-called albedo (retroreflective power) comprised with the distance between the module and the surface greatly influence how high the additional generated yield is at the rear end.

Depending on the nature of the reflective surfaces and the installation height of the module, the yield can be up to 25% higher.

ALBEDO*

Albedo is a measure of the retro-reflectivity of diffuse reflection, i.e. non self-illuminating surfaces..

In the case of a bifacial solar cell, the back surface field, which is normally covered entirely with aluminium, is printed with an aluminium grid approximately at the front of the solar cell. The application of this grid enables indirect light from the solar cell to be picked up on the back and converted into electrical current.

The bifacial additional yield is dependent on the area of reflection. The higher the albedo, the greater the reflected radiation. An additional yield of up to 25% can be achieved. With an albedo of 30%, an 11% higher yield was achieved within one year.
