To accomplish an enormous demand of power with solar energy, a cost effective and optimum system has to be developed which works in synchronisation with the existing grid. The Government in developing countries like India is providing momentous opportunities and marvellous schemes to promote renewable energy sources like solar for generating power. This paper aims to analyse the generation of power from solar photovoltaic (PV) systems economically and efficiently as it is always a challenge for the design engineer to develop an economical and efficient solar PV system. Apart from technical issues, structural aspects also affect the power generation from PV modules. This paper proposes an innovative design of non-movable tracking system that enhances the power generation of PV modules by just providing two grooves in the mounting structure in place of the tracking system. A formula for the optimum space calculation for PV installation is also proposed in this paper. A comparative analysis of total annual energy generated by the hardware setup and the results obtained using software of the rooftop solar PV system has also been analysed for practical consideration. To verify the results, first, the system has been simulated using the PVSYST software considering all practical and existing realistic losses like PV loss due to irradiance and temperature, array soil loss, module quality loss, array mismatch loss, ohmic wiring loss, and inverter loss which formulate a bonafide case of consideration and then hardware implementation of the proposed system. The hardware and software results have been compared to analyse the proposed topologies adopted to address the aforesaid problems.

Climate change is currently a large concern for human society, particularly our high dependence on fossil fuels. A considerable amount of research effort is focused on renewable energies, especially solar photovoltaic (PV) generation systems. For solar PV systems, energy conversion efficiency is an active research topic, with many approaches being developed to solve this problem. One of these approaches is solar tracking systems, where the solar PV moves with the sun in order to capture the maximum direct solar radiation. This paper proposes a solar PV single-axis tracking system and compares the energy conversion efficiency with respect to a fixed solar PV installation. The proposed mechanical system is based on a servomotor moving a PV on a shaft, covering 180 degrees. A sevenelement sensor is used to measure and estimate the angle of maximum solar radiation. Also, a control system was used to obtain the optimal power output from the solar PV. The system was tested in Fusagasugá, Colombia, which is located in the tropics region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
