Improving Solar Panel Inspection with Infrared Imaging
In 2019, about two percent of the world''s total electricity came from photovoltaic solar panels. In the United States, about 3.27 percent of electricity was generated by photovoltaic cells, and solar accounted for 4.37 percent of the United Kingdom''s electricity. Compared with twenty years ago, these are impressive numbers.
In the latest episode of FLIR Delta, we will answer the four most commonly asked questions about using thermal drones in solar panel inspections.• Why use a ...
How to find photovoltaic ground faults | Isolation resistance testing ...
To understand all components of the PV array, we can not just focus on individual solar panels. PV array faults may be more easily found and mitigated, once we understand how all the components of the PV array play together. First, we have the Equipment Grounding Conductor (EGC). This is the conductive path, that provides a …
