Further parameters for solar energy - Adapting to environmental conditions

Besides the solar irradiance other meteorological parameters are relevant for solar power plants. Scientists of the department Qualification determine various parameters which are used to qualify solar resources and solar power plants. In particular, the operation of power plants must be adjusted to the site specific special environmental conditions. Therefore, many activities of our department are carried out in collaboration with the enerMENA Meteonetwork on various sites in the Middle East and North Africa (MENA), in addition to the facilities at PSA (owned by the Spanish research center CIEMAT), Jülich and Cologne. Thus, our scientists obtain realistic insight into the meteorological conditions of this region and the challenges that project developers face. For many phenomena aerosols play an important role. The models and measurements methods used by DLR include:

  •  Spectroradiometer system for global horizontal and direct normal irradiance. Source: DLR

    Determining the aerosol-optical thickness and the properties of the aerosol with an AERONET sun photometer
  • Modelling solar spectra and their influence on solar plants and radiometers
  • 3D wind measurements with high temporal resolution of the dynamic wind loads on collectors and receivers because these influence the efficiency of solar power plants
  • Modelling and measuring the atmospheric extinction in CSP plants
  • Measurement of particle concentration with particle counters
  • Modelling and measurement of dew, measurement of ground humidity and ground temperature
  • Height profile of the aerosol extinction coefficient with LiDAR systems

The Analysis of aerosols in the lower atmosphere also leads to synergies with the group for durability of components of our department.
