Abstract
This study presents the optimal design of a PV-diesel generator-based electricity system for the selected location in Kharar, Punjab, India. The system architecture consists of a generic 1kWh Lead Acid battery, a 10.2 kW flat plate PV system, a 4.69 kW System Converter, and an autosized 4.70 kW diesel generator. The analysis includes important metrics and results. The Total Net Present Cost (NPC) and the Levelized Cost of Electricity (COE) for the proposed system are not provided in the available information but are integral for evaluating the economic feasibility. The estimated Operating Cost is $65,209.06, and various cost components are categorized and analysed. The electrical production of the system is detailed, with an average electrical output of 1.94 kW and a capacity factor of 19.0%. The total annual production from the PV system is 16,989 kWh. The diesel generator's fuel consumption is measured at 20.5 L annually, with a specific fuel consumption of 0.297 L/kWh. This information is vital for assessing the sustainability and operational aspects of the system. The study evaluates the performance of the lead-acid batteries, indicating the string size and other technical specifications. The renewable penetration of the system is impressive, with 68.4% of the total capacity being renewable, and 99.6% of renewable production meeting the load. In conclusion, the presented design showcases the potential of a PV-diesel generator-based system in providing electricity in Kharar, Punjab, India. It demonstrates the feasibility of incorporating renewable energy sources alongside a diesel generator, highlighting the system's strong renewable penetration. Further economic evaluations and environmental considerations are required to make informed decisions regarding its implementation and sustainability.
