Design of Photovoltaic monitoring and service using IR Imaging

Project Overview

Photovoltaic is one of the renewable energy sources. This renewable energy source is considered one of the best alternatives for non-renewable sources. but with photovoltaic we notice that there is some drop of efficiency in the panel in the term of producing electricity; And there are many factors That could affect the panel such as excessive heat and dust. In this cause, the panel should be studied and analyzed along with the data it provides to protect and to choose the best material suitable for the conditions the panel subjected to. One of these studies is infrared imaging. IR imaging detect any cracks and problems in the solar panel where we get to know what should be replaced. Within time the solar panel are subjected to thermal and mechanical stress in which an IR sensor or camera is possible to detect.

Infrared Imaging Defects such as cracks or interconnection mismatches in solar cells are a genuine problem for Solar panels despite the differences in the weather a panel subjected to. They are hard to avoid and it is impossible to quantify their impact on panel’s performance during its lifetime. it is reported that as a field solar panel ages and is subjected to thermal and mechanical stresses, which results in an inactive cell with significant hot spot heating effect. One of the indicators using Infrared imaging are hot spots, which are areas on the panel with high temperatures, were used as effective indicators to diagnose the defective portions of the solar panel. Infrared images of panel surfaces are to be captured also to observe temperature distribution over the surface of the solar panel. There are two temperature points to be noted (hottest and coldest point) by moving the scanner across each cell of the panel. The measurements are to be taken during a period of good insolation in a clear sky.
