| Summary: | This paper presents and evaluates the potential of using solar energy in selected transportation vehicles
to minimize fuel consumption and toxic emissions. The main objective of the monograph was to develop
a mathematical model of the course of bus roof lighting as a practical tool for planning the efficiency
of photovoltaic technology for a specific vehicle operating in a specific location. Based on geographic
location, estimation of sunlight availability, interference with bus roof lighting and irregularities in
vehicle operation, the amount of electricity generated by photovoltaic modules was modeled. It was
hypothesized that a photovoltaic system placed on the flat roof of a city bus in Lublin, located at 22°34′E,
51°15′N (eastern Poland), receives less solar energy than a system placed in an open, unshaded area.
The paper analyzes available photovoltaic panel solutions for automotive applications. A database and a method for measuring total solar irradiance (irradiance) were selected. The amount of solar
energy reaching four different city buses was determined and compared with the values obtained for
a stationary object, taking into account the time variation: year, season, month, day and time of day.
The annual reduction in solar irradiance was compared in two submodels: maximum solar irradiance
and mileage, which amounted to 19% and 31%, respectively. The submodels were based on time series
of measured data from four city buses.
The final part of the study analyzed the use of solar energy in a photovoltaic system installed on
the roof of a city bus. The measured green energy produced from the photovoltaic system on board
the short and long buses replaced 10% (398 kWh) and 27% (1261 kWh) of the energy produced from
fuel chemical energy in the alternators, respectively. In the context of the proposed solution for electric
vehicles, this system will allow them to increase their range. |
