Performance of low-cost solar radiation logger

<p>In solar power systems, irradiance value data are among the most important parameters. Such can be used in installing photovoltaic (PV) modules, such as determining exact location, tilt angle, and required area, for optimal efficiency. In this study, comprehensive simulation implementation of a radiation meter with PV cell temperature sensor presented. The measurement is based on reading generated by small capacity at specific load converted into digital microcontroller using implicit Newton polynomial interpolation (NPI) equation low-cost alternative method. effect included conversion to obtain precise results. Firstly, structure characteristics discussed. Secondly, parameters, measuring method, NPI presented assess Finally, PSIM hardware conducted validate concepts compare their proposed has an average error 2.72% test.</p>
