Systematic Design and Simulation of a Home Stand-Alone PV System for a Located in Baghdad City

Designing a stand-alone photovoltaic (PV) system for a home is a captivating and forward-thinking endeavor that has gained significant traction in recent years. The primary objective of such a system is to enable homeowners to generate clean and sustainable electricity on their premises, thereby reducing their carbon footprint and energy costs while gaining energy independence. A stand-alone PV system, also known as an off-grid PV system, operates independently of the traditional electricity grid. This makes it an ideal choice for remote or rural areas where grid connectivity may be unreliable or unavailable. Additionally, stand-alone PV systems are appealing to environmentally conscious homeowners who seek to reduce their reliance on fossil fuels and minimize their impact on the environment. The core concept behind designing a stand-alone PV system is to harness sunlight using solar panels, convert it into electricity, and efficiently store the excess energy in batteries for use during periods of low sunlight. This ensures a consistent and reliable power supply, even when the sun is not shining, which is crucial for maintaining the comfort and functionality of a modern household. Almost all types of applications can make use of photovoltaic systems to harness solar energy. Stand-alone renewable energy sources based on photovoltaic systems and battery storage systems are starting to play a significant role in supplying power all over the world. In the Iraqi city of Baghdad, all the city’s energy needs could be met by renewable energy. Solar energy will play an important role in Baghdad. In order to provide a family with the necessary electricity, this paper will demonstrate the design and simulation of a standalone photovoltaic (PV) system for a home in Baghdad. PVsyst software, which is a potent program for designing, simulating, and generating PV system reports, was used for the design and simulation. PVsyst uses advanced algorithms and databases to simulate solar energy systems’ performance. Thus, users design optimized systems for their locations, meteorological data, and electrical load. A stand-alone PVsyst was designed and simulated to provide 4 kW load power to a house in Baghdad. The main results were 1635 kWh/kWp/year with a 71% performance ratio.
