Design, Operation and Maintenance of PV Systems: A Review

Abstract

Renewable technology is becoming increasingly important in the production of electricity nowadays. As they are non-renewable sources of energy that lead to environmental emissions, fossil fuels do not offer a viable choice for the future.Photovoltaic energy is the most commonly used source of green energy, and this is attributed to the vast amount of solar power across the world. The major developments in photovoltaic systems (regardless of the performance of the various technologies) are currently focused on improving the architecture of photovoltaic systems, and also the efficient operation and maintenance of these systems.This thesis aims to study photovoltaic systems, where the key points of these systems are architecture, operation and maintenance. The essential elements of the device and their own configuration are updated throughout the design. The basic operation and the operation of hybrid systems, and also the power efficiency, was checked with respect to the operation. Ultimately, their efficiency, thermography and electroluminescence, soil, hazards and failure modes were studied in relation to the maintenance of PV systems.
