Abstract
It is known that a solar beam crossing a window losses 10% of its incident power. Yet, this affirmation is not supported by many published scientific evidences. In this work, a heat flux mapping method was used to determine the heat flux distributions at the focal spot of a solar concentrating device without and with a window on the incident beams' trajectory. The presence of a window on the beams' trajectory induces a 12% loss of the total power and a 11% decrease of the peak heat flux density.
