Solar Operated Weather Forecasting Station

Abstract

The electrical energy generated by PV systems depends mainly on the available solar radiation reaching the PV modules. Tracking systems ensure that the sun's rays fall perpendicular on the active surface of the PV module. Improving the efficiency of solar panels is the main task of solar energy generation. One of the methods is a solar tracking system. The most critical parameters of tracking systems is a precise orientation to the sun. This paper presents the outline and execution of a simple, easy and cheaper automatic, Aurdino based single-axis solar tracking for weather forecasting station application. In this paper, single-axis solar trackers' performance based on schedule and light-dependent resistor (LDR) photosensors and a stationary photovoltaic installation in various weather conditions has compared. A comparative analysis of the operation of a manufactured schedule solar tracker and an LDR solar tracker in different weather conditions for one year has performed; also, a simple method for determining the rotation angle of a solar tracker based on the encoder has proposed.
