Analyses of the influence of aerosols on the yield of photovoltaic systems contribute to better utilisation of electricity grids and to making the energy transition more secure. A measurement campaign in Allgäu as part of the MetPVNet project provided important data for estimating the production of solar electricity. Photo: Jonas Witthuhn, TROPOS

Air quality models can improve the accuracy of forecasts of daily solar power production in the future

Analyses of the influence of aerosols on the yield of photovoltaic systems contribute toward a better utilisation of electricity grids and the energy transition.
