Currently, most of the world’s energy is derived from fossil fuels (World Energy Resources 2013 Survey). Fossil fuels are a limited resource and might not be able to meet the future energy requirements of the world for too long (Shafiee and Topal 2009). Apart from being non-renewable, these are also significant contributors of greenhouse gases to the environment leading to air, water and land pollution (Marland and Rotty 1984). Due to the nature of these resources there is an urgent need to conserve these resources. It is also important to explore alternative energy sources for the future.To this end, multiple solutions have been proposed. One of the most promising technologies is solar energy. Solar energy can be harnessed using different type and iterations of a solar panel. In this paper, we will focus on roof mounted grid connected PV systems. Not only do these systems provide clean energy, but can also contribute to the mitigation of greenhouse gas production (Sims et al. 2003). Though operation of a PV system does not consume any substantial energy, the manufacturing of a PV system is a very energy intensive process. To determine and quantify the CO2 emissions mitigation potential and net energy yield of these systems , it is important to determine the EPBT and GPBT of PV systems.
The net energy yield of a PV system may be defined as energy returned on energy invested (EROEI or…
