In recent years, great efforts have been made to reach a consensus on heliostat testing best practices. A specific SolarPACES task was launched to provide a Heliostat Testing Guidelines document for single heliostat evaluation with a focus on prototy

A new measurement system able to measure the shape accuracy of complete mirrored heliostat modules in series production was developed. The applied deflectometry measurement method is based on the reflection of regular patterns in the mirror surface a

The hydrogen formation of diphenyl oxide (DPO) / biphenyl (BP) based heat transfer fluids (HTFs) can cause undesirably high concentrations of the gas in the HTF system of solar thermal parabolic trough plants. Hydrogen permeates from the HTF into the

Distribution of heliostat aim points is a major task during central receiver operation, as the flux distribution produced by the heliostats varies continuously with time. Known methods for aim point distribution are mostly based on simple aim point p
