-  * ListenpunktInfrared ​radiation coming from natural sunlight can cause a heat build-up inside building, resulting in thermal imbalance under hot climate conditions. Measurements carried out with a-Si photovoltaic glazing show a significant decrease in radiation transmission of 780nm-2500nm range (near infrared, N-IR), up to 90%.+  * Infrared ​radiation coming from natural sunlight can cause a heat build-up inside building, resulting in thermal imbalance under hot climate conditions.

   * Due to the greenhouse effect, the temperature of the interior rises when the g-value increases. The g-value and SHGC (Solar Heat Gain Coefficient) indicates the amount of energy that goes through a glazing. The a-Si technology of Onyx Solar provides a great protection from such factor, limiting the g-value to the range of 10-40%.   * Due to the greenhouse effect, the temperature of the interior rises when the g-value increases.

   * Another key factor to consider when choosing the right glazing is the negative impact of ultraviolet (UV) radiation into the interiors, on furnishings,​ and to people. The architectonic photovoltaic glazing filters up to 99% of the ultraviolet radiation. Regarding the light reflection produced by the photovoltaic glass, values go from 7 to 9%. These values are similar to conventional glazing which normally ranges from 6 to 10%.   * Another key factor to consider when choosing the right glazing is the negative impact of ultraviolet (UV) radiation into the interiors, on furnishings,​ and to people.
