Design of a dual solar-electric indoor lighting reinforcement system

The increasing energy consumption in the country is becoming one of the major economic and social problems. Although our beloved country is very rich in fossil and non-renewable energy resources, inefficient energy consumption imposes irreparable damage on the country's budget and ultimately makes the future unclear. The high cost of electricity production on the one hand and the limited consumption on the other hand, in addition to the previous reasons, double the importance of improving consumption and using more renewable resources. In the present study, the design of a system has been investigated, which can be used to reduce electricity consumption to zero for daytime lighting and greatly reduce energy consumption for nighttime lighting. The aim of this study is to generally investigate the use of solar energy and lighting in reducing electrical energy consumption. It is clearly visible that the high cost of solar equipment has limited the attention of consumers and energy engineers to using this type of production. Therefore, in this work, much attention has been paid to the simplicity and cheapness of the design and an attempt has been made to produce this system with the minimum equipment available in the Iranian market. In order to ensure the accuracy of the results obtained, the results were first compared with other valid results, which showed acceptable accuracy in all sections. The results obtained show that in the sunlight receiving section, which is the main focus of this research, the final designed trackers achieve high accuracy. By using instantaneous tracking in this system, we always benefited from this accuracy in practice. The next sections of the system are presented as an analytical design and a suitable combined system for lighting and providing light to buildings is introduced. According to the results obtained, the initial claim of the efficiency of this system and reducing electricity consumption has been proven.
