Photovoltaic Testers for Facility Power Monitoring


Solar-powered devices are an important part of achieving a cleaner, more sustainable world. To make these devices effective and scalable, realistic and repeatable test conditions must be created.


With the help of a photovoltaic tester, it will be a complete electrical test solution for determining the performance of photovoltaic arrays. This device collects vital data that will assist a technician to review trends or common problems for the current and future conditions.



In the solar energy industry, photovoltaic test equipment is frequently used for analysis. It measures and analyzes the I-V (current vs. voltage) and P-V (power vs. voltage) characteristics of solar energy. It demonstrates the photovoltaic effect, photochemistry, and electrochemistry using semiconducting materials. These tools are widely used in electrical system commissioning, auditing, and troubleshooting. With them, curve populations can be quickly analyzed, providing outliers and data for future performance monitoring.


Solar Panel Testers have become increasingly in demand in recent years as PV technology has become more affordable and popular. There are numerous tools available for performing various tests on PV systems. Fluke, a manufacturer of handheld test instruments, is currently one of the leading suppliers of tools and testers. Fluke solar testing equipment covers everything from solar irradiance meters and photovoltaic testers for residential use to commissioning a new PV array or performing routine maintenance on a solar farm or photovoltaic power station. Read on for a more in-depth look at each area of test.


Solar Panel Commissioning Tests


Commissioning tests are performed to ensure that PV systems are operating safely and in accordance with predetermined safety standards. IEC 62446, the primary PV safety standard, specifies the minimum testing requirements that must be met each time a PV installation is connected to the grid. Fluke provides a tool specifically designed to perform these tests quickly and safely. It can check the continuity of protected conductors and connections as well as measure the insulation resistance of active conductors.


Solar Panel Performance Testing

Regular PV system maintenance requires performance testing to be successful. Without regular monitoring of a photovoltaic installation, it would be impossible to compare performance numbers and thus difficult to judge system efficiency over longer time periods. Fluke provides a number of instruments for performing performance tests.


Troubleshooting Solar Panels

Troubleshooting is an important application in any field because it entails locating and correcting the source of a failure or malfunction. This is especially important when dealing with photovoltaics because total failure means a loss of electricity, which could have a significant impact on daily life on a larger scale. It is also possible that a PV system will not completely fail, but one or more modules will malfunction. In this case, the PV system’s efficiency will suffer, indicating that troubleshooting is required.
