What is the reflectivity of ceramic tiles to solar energy?

It can be seen from the research of this paper: the reflectivity of ceramic tiles to the solar energy is not high, the maximum is about 60 % and the lowest reaches 17.3 %; from the point of view of color, the color of ceramic tile is more light, its reflectivity is higher; the color is darker, the reflectivity is lower.

How do ceramic tiles absorb solar energy?

The average reflectivity of the ce- ramic tile material to the solar radiation is obtained by dividing the spectral band intervals. Thus, the absorption characteristics of the ceramic title to the solar energy can be understood. Planck’s law reveals the relationship among the radiation of black body, the wave- length, and the temperature.

Do solar roof tiles affect domestic consumers?

However, the progress in the development of solar roof tiles is contribute to minimal layer thickness. That ca n contribute to the reduction of the prices of the solar the roofs. The lack of contextual analysis and the signi ficant gaps in the researchers propose the industries to affect domestic consumers positively.

Does ink-jet decoration affect solar reflective properties of ceramic tiles?

However, the productive process used to obtain ceramic tiles limits the SR values due to crystallization. It was also found that ink-jet decoration negatively affects the solar reflective property of the tiles prepared with the new engobe due to its coverage by the inks and their mineralogical composition.

How much solar energy is absorbed by tiles?

The maximum is about 60 %, and the lowest reaches to 17.3 %. Thus, it is a kind of strong solar energy absorbing material. Thus, the extensive use of the tiles as outer decorative material should be avoided to save too much solar energy in order to cool the building in a hot summer.

Are solar reflective ceramic tiles effective against UHI?

One of those solutions is reflective tiles, as they absorb less heat and stay cooler than traditional materials and are considered an effective mitigation technique against the UHI phenomenon. This study investigated the obtaining of solar reflective ceramic tiles through the modification of the engobe's formulation.
