The Glint and Glare Assessment for Solar-Thermal plants shows potential for improvements
September 2016 - Zehndorfer Engineering finalizes a Solar Glare Assessment for several Solar-Thermal Plants situated on a building compound to be constructed in Villach / Austria. The installations are distributed on several roofs and meant to contribute to the hot water generation in the flats below. The survey was ordered by the Villach City Government in an administrative assitance procedure. The solar installations, to be built on several newly planned buildings, triggered concerns about glint and glare with regard to the residents of neighboring buildings as well as the road nearby.
The Glint and Glare Calculation indeed showed a glaring hazard of some of the installations, which could be abated almost completely by reducing the elevation of the solar collector panels, thus not causing any additional costs. Glaring in the direction of the closely located street was found to be negligible.
