The new measuring system works without a moving bar, only with a digital camera and calculates the flux density on the basis of the raw image data. So far there has been no workable system for commercial power plants. It is therefore only used for smaller prototype measurements in test facilities. Solar flux install#Up to now, flux density measurements were only possible using so-called moving bars – an expensive and complex to install and at the same time error-prone system. The solar flux density, on the other hand, is a direct measure of the intensity with which the concentrated sunlight hits the receiver. However, these methods only determine the radiation distribution indirectly by looking at the heat development. In order to be able to optimally align the power plant’s heliostats, the power plant’s control center therefore not only needs information on the position of the sun and the expected solar radiation, but also on the radiation distribution on the receiver.Ĭonclusions can be drawn, for example, from temperature measurements using sensors or infrared cameras. Such an uneven distribution of solar radiation causes accelerated aging of the receiver and leads to higher heat losses. However, it can happen that the mirrors are aligned in such a way that so-called hotspots arise, for example. If the radiation hits the entire surface of the receiver with an evenly distributed intensity, the energy yield is highest. There a receiver picks up the radiation and converts it into heat. In a commercial solar tower power plant, tens of thousands of individual mirrors bundle the sunlight and reflect it onto a surface at the top of the solar tower. How much concentrated solar radiation is arriving? As part of its annual conference, SolarPACES honors an outstanding new technology with the SolarPACES Technology Award every year. The SolarPACES Technological Cooperation Program (Solar Power and Energy Systems) under the umbrella of the International Energy Agency IEA is the leading international network of researchers in the fields of solar thermal power generation and solar chemical systems. Solar power plants can use the information to better align the heliostats, which increases the lifespan of the receiver and the efficiency of the power plant. The measurement results show the intensity with which the concentrated solar radiation hits the surfaces of the receiver. The measurement method they jointly developed calculates the solar flux density distribution on the receiver of solar tower power plants in real time. This year’s SolarPACES Technology Award goes to a team of researchers from the DLR Institute of Solar Research and CSP Services.
