Electrical equipment designed for a particular environmental condition may not provide satisfactory performance under other conditions of temperature and humidity. Specifically in the case of solar PV inverters, the efficiency and other system characteristics may vary as per the extreme climatic conditions at the place of installation. Here a comparative study of solar PV inverter performance under such extreme conditions is presented in terms of system efficiency and insulation resistance. The conditions as per relevant international standards are simulated in a climatic chamber and five samples are studied for the effect of extreme temperature and humidity conditions. It is found that the insulation resistance of few samples is varying drastically which will affect the system safety. Similarly the efficiency of the system is also affected. Similarly there is considerable change in the system efficiency also.Keywords

Performance of a SPV system is dependent on temperature, array configuration, solar insolation, shading across it etc. The conversion of solar energy using SPV modules comes with its own problems that arise from the change in insulation conditions. These changes in insulation conditions severely affect the efficiency and output power of the SPV modules. For improving the efficiency of conversion of solar energy can be done by tracking the maximum power point of a PV module. There are so many types of MPPT charge controllers for doing this important work in SPV system. A dc-dc converter is essential in SPV system as it acts as an interface between the load and the SPV module. Three different basic types of converters are explained in this paper without any non-idealities. There are other types of dc-dc converters as well, but these converters from these three basic converters. Further by using these dc-dc converters the performance of the MPPT algorithms can be done for improving the overall efficiency of the SPV system.Keywords

The key requirements for the control of the solar photovoltaic (SPV) energy conversion systems are to achieve very fast yet quite accurate tracking of the maximum power point under rapidly changing environmental conditions and to obtain efficient unperturbed tracking operation under steady environmental conditions. In this work, a high-performance Maximum Power Point Tracking (MPPT) technique, based on one cycle control (OCC), is proposed to meet these challenging requirements. This paper proposes single phase z-source inverter with maximum power point tracking using OCC for solar photovoltaic power generation. OCC is based on output current adjustment according to the voltage of photovoltaic array so as to extract the maximum power from it. A 1 kW grid-tied roof-top system is designed using the OCC method for MPP. Analysis & simulation using MATLAB tool, is carried out to validate the proposed technique.Keywords
