Environmental concerns, sustainability and energy security demand new and alternative forms of transportation. Plug-in hybrid electric vehicles (PHEVs) are getting more and more attention due to their rechargeable aspect and ability to utilize alternative sources of energy. If the energy used to charge the batteries of a PHEV is obtained from clean and renewable sources, these vehicles will emit less CO2 emissions and consume less fuel. In this study, solar energy is used as clean and renewable energy source to charge PHEV batteries. The scope of this study is to design a photovoltaic battery charging system to propel a PHEV for 32 km per day on pure electric mode and achieve the goal of reducing daily fuel consumption by 50%. The proposed solar energy system is envisaged to be installed on the roof of a house. The daily measurements of stored energy via solar panels show the viability of this approach and the potential of traveling on renewable sources of energy without burning fossil fuels.
