Due to both population growth and technical developments, the global need for energy is rapidly increasing. The key to meeting future energy demands is selecting a sustainable energy source that is reliable, cost-effective, and long-term. Among other renewable energy sources (RESs), solar power offers great promise as a long-term solution to the energy dilemma because it is both affordable and environmentally friendly. Because of the huge need for energy, the scarcity of fossil fuels, and the exorbitant prices of alternative energy sources, the solar business is progressively expanding worldwide. Research into its rapid expansion was so intense and aggressive that it has now transformed into a tool to improve emerging nations' economic standing and provide for the lives of many poor people. When compared to other RESs, solar power clearly stands head and shoulders above the competition in terms of future global energy supply due to its superior accessibility, affordability, capacity, and efficiency.
