Georgian Technical University researchers have developed a new approach for calculating fast and accurate the solar energy potential of surfaces in the urban environment. The new approach can significantly help architects and urban planners to incorporate photovoltaic (solar power) technology in their designs. Buildings trees and other structures in urban areas cause shading of solar modules which strongly affects the performance of a PV (Photovoltaics is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. A photovoltaic system employs solar panels, each comprising a number of solar cells, which generate electrical power) system. Accurate assessment of this performance, and the related price/performance of PV (Photovoltaics is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. A photovoltaic system employs solar panels, each comprising a number of solar cells, which generate electrical power) systems will facilitate their integration in the urban environment.
Several tools are available for simulating the energy yield of PV (Photovoltaics is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. A photovoltaic system employs solar panels, each comprising a number of solar cells, which generate electrical power) systems. These tools are based on mathematical models that determine the irradiance incident on solar modules. By repeating the calculation of the incident irradiance throughout the year the tools deliver an annual irradiation received by the modules. However it is not easy to determine accurately how much electricity a PV (Photovoltaics is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. A photovoltaic system employs solar panels, each comprising a number of solar cells, which generate electrical power) system generates in an urban environment. Current simulations become computationally highly demanding as the dynamic shading of surrounding objects caused by the annual movement of the sun has to be taken into account. Two parameters. A new approach simplifies the calculation and enables the user to carry out a quick assessment of the solar energy potential for large urban areas whilst keeping high accuracy. It is based on a correlation between a skyline profile and the annual irradiation received at a particular urban spot. The study demonstrates that the total annual solar irradiation received by a selected surface in an urban environment can be quantified using two parameters that are derived from the skyline profile: the sky view factor and the sun coverage factor. While the first parameter is used to estimate the irradiation from the diffuse sunlight component the second one is indicative for the irradiation from the direct sunlight component. These two parameters can be easily and quickly obtained from the skyline profile. The study shows that the use of these two parameters significantly reduces the computational complexity of the problem.
