Abstract:
With the recent development and success of Vehicle integrated photovoltaic
(VIPV), the efficiencies and power capacities of EVs (electric vehicles) and PHVs (plugin hybrid vehicles) has extremely improved. Especially VIPV has improved the
continuous charging and discharging cycles of EVs. Modern researchers are working on
the development of fully solar operated vehicles. So, there is a need to re-establish
meaningful practical modeling and simulation of solar irradiance for the vehicleintegrated PV, rather than an extension of the existing technology. This is a well-known
fact that PV energy is directly proportional to the Solar irradiance. Once solar irradiance
energy density is explored, it will help the designers of solar systems and those of the
electric vehicles as well. It is also helpful to estimate solar power output of Vehicle
integrated PV. It is also obvious that the solar irradiation depends on many factors, such
as curvature & Orientation of the surface, solar angular position, time and date of year,
geographic location, humidity, cleanliness, altitude and climate. In this work,
mathematical expression is derived for an expected curved surface to estimate varying
solar irradiance energy density throughout the curved surface. Although the same curved
surface was simulated using the Autodesk Revit (version: 2019), the mathematical solar
irradiance model was verified. The main objective of this research is to draw model for
estimation of solar irradiance density on the curved metal surface so that we can predict
the energy output from the EV car surface.
