The sun-pointing sensor is used in solar energy tracking systems to capture maximum power by photovoltaic (PV) cells or systems at the time of uniform or partial irradiance of the sun and effect of shade during clouds. PV cells or modules’ generating power is affected due to partial shading.
This paper presents an overview of the current state of the developments in sun position sensors used in solar technologies such as photovoltaic modules, satellites, solar collectors and other applications. The working principles and geometric designs of several types of sun position sensors are discussed in detail.
Sun tracking system provides a solution to fixed photovoltaic panels which lost their productivity when sun is not in the range of optimal angle. Solar trackers are designed to follow the location of the sun which results in the 10–25% more output efficiency of the PV panels.
The proposed device automatically searches the optimum PV panel position with respect to the sun by means of a DC motor controlled by an intelligent drive unit that receives input signals from dedicated light intensity sensors. The solar tracking PV panel produced more energy than fixed one with about 57.55%.

6 FAQs about [Principle of Photovoltaic Panel Rain Sensor]
What sensors are used for Monitoring photovoltaic (PV) plants?
Abstract: This article presents state-of-the-art sensing techniques used for monitoring photovoltaic (PV) plants. They are grouped into cameras, which are typically two-dimensional (2-D) cameras and non-cameras-based techniques.
What are the sensing techniques used for Monitoring photovoltaic (PV) plants?
Most of the current review papers were less comprehensive and they mainly focused on academic works. This article presents state-of-the-art sensing techniques used for monitoring photovoltaic (PV) plants. They are grouped into cameras, which are typically two-dimensional (2-D) cameras and non-cameras-based techniques.
Can sun position sensors be used for photovoltaic panels?
Fontani et al. proposed two models of sun position sensors for photovoltaic panels, for comparing their precisions. Each prototype was composed of a pinhole without lenses, an image sensor, and a black cylinder. The sensors were divided into two sections, as shown in Fig. 41.
How does rain interact with the surface of PV modules?
Rain interaction with the surface of PV modules From a physical viewpoint, a water drop deposited on an ideal flat homogeneous surface is a system composed by three boundaries (solid/water, solid/air and water/air), where the water/air interface forms a static contact angle 1 θ (see Fig. 3) with the water/solid interface .
How a solar tracker can improve the efficiency of a photovoltaic panel?
But the continuous change in the relative angle of the sun with reference to the earth reduces the watts delivered by solar panel. In this context solar tracking system is the best alternative to increase the efficiency of the photovoltaic panel. Solar trackers move the payload towards the sun throughout the day.
Can solar tracking systems be used for performance analysis of solar PV system?
The observation has been made from the comprehensive literature review on the sun tracking systems for performance analysis of solar PV system. Available literature suggested the various performance components and/or parameters, importance, use of controller, system efficiency, tracking control strategies and economic assessment.
