Introduction
Photovoltaic systems are an important contribution to the the energy transition, and to a sustainable handling of resources – in recent years, driven by state subsidies, numerous smaller and larger photovoltaic systems have been installed in many countries in the world. After the boom phase, the maintenance of existing plants in particular is gaining in ignificance. This practical guide explains how thermography can support you during commissioning, documentation and maintenance, and provides helpful tips for using a thermal imager.
Motivation and reasons for using thermography
Detecting poor quality on the markets.
In the boom years of photovoltaics, the order books were full and solar engineers were hardly able to keep up. This meant that it was not just highly trained trade experts that were filling orders. Large numbers of cross-trade and inadequately qualified contractors helped to meet the huge demand. The consequences are still being felt today: Construction errors, inadequate solar electricity yields from the plants, up to security and fire risks. It is primarily the plant operator who suffers. However, a qualitatively inferior implementation also reflects on the the company doing the work, potentially allowing damage claims to be allowed based on a thermographic analysis.
Thermal irregularities point to a possible loss of electricity yield.
