Interdependencies Between Photovoltaics and Thermal Microclimate
Climate change can only be reduced to a minimum when increasing the share of renewable energies. Thus, the definition of climate protection goals led to an increasing number of photovoltaic installations worldwide in recent years. At the same time, especially urban areas are already suffering from the consequences of climate change: Heat waves during summer months and reduced night-time cooling lead to negative impacts on the human organism and health. Within this context, the present review investigates interdependencies arising between photovoltaic panels and outdoor thermal microclimate, particularly in urban areas. In a first explorative, then systematic literature research approach, relevant publications were identified and selected based on distinct criteria. The studies were classified into the following main categories: (i) impacts of photovoltaics on the thermal microclimate; (ii) impacts of thermal microclimate on photovoltaic performance. The literature is then accordingly analyzed and main interdependencies, parameters and metrics are identified. The results, however, are incongruent, reaching in category (i) from ‘solar cooling’ of the surrounding ambient air temperature of up to −1.8 K to ‘solar heating’ of up to 4 K. Hence, further research, both experimental and simulationSimulation-based, is required to comprehensively understand the interactions between photovoltaics and its thermal surroundings.
