Data confidence 85 high

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

This paper presents a new approach to the solar tracking control. Today several methods are used to minimize the angle of incidence between the incoming sunlight and the photovoltaic (PV) panel. Most of them require optical solar sensor(s) to maximize energy output. There are approaches where geolocation data and the timetable of the Sun's position support a solar tracking mechanism. This paper proposes a novel sensorless (no optical or geo positioning sensors required) solar tracking mechanism based on a maximum power point tracking (MPPT) control for a mobile autonomous PV system. Such a system would provide an automatic PV panel position adjustment towards the Sun using a sensorless 3-DOF solar tracker system with a MPPT based control.
