New approach to measure the solar potential of urban areas
Dutch people propose a new approach to measure the solar potential of urban areas. It is based on two parameters modelled in relation to the skyline:
the sky view, i.e. the relationship between the visible sky and a hemisphere centred on the analysed location; it determines a useful urban spatial indicator for radiation and the thermal environment; and the solar cover, which determines irradiation by direct sunlight. These two parameters can be easily and quickly obtained from the Skyline profile.
According to the researchers, the maximum estimation error of the model is less than 10%, and the system also offers a substantial reduction in the computational requirements needed to determine the efficiency of photovoltaic systems in complex urban environments.
The model is applicable to all latitudes, as it incorporates five coefficients that depend on the local climate.
