Diagnosing Solar Panel Faults with Drone Thermography

Diagnosing Solar Panel Faults with Drone Thermography

Thermal Solar PV Fault Detection

Using photovoltaic solar panels to meet some or all  your electricity needs is a great investment, now more than ever. However, your panels need to be functioning correctly if that investment is to be maximised.

Regular Solar Panel Checks
Many solar panel owners don’t know how their installation is performing and of course, as most installations are on rooftops, it can be difficult to physically check them. Also, faults are not always visible to the naked eye! This is where an annual drone thermography inspection can give you all the information that you need with just one or two easy flights conducted by a qualified thermographer and certified drone pilot.

When your system was installed, the installation company would have given you a performance estimate that you can use as the benchmark to monitor your panels and make sure they are working as hard for you as possible. Checking the display on your inverter or your accompanying app can easily demonstrate if your solar panels are under performing and if you find that they are not, it’s time to get in touch with a professional to get any faults diagnosed.

How Do Solar Panels Work?
A standard solar panel or module consists of a layer of silicon cells, a holding frame, a glass covering, and various wiring to allow current to flow from the silicon cells out to the convertor. Silicon is a nonmetal with conductive properties that allow it to absorb and convert sunlight into electricity. When light interacts with a silicon cell, it causes electrons to be set into motion, which initiates a flow of electric current. This is known as the “photovoltaic effect,” and it describes the general functionality of solar panel technology.

How To Detect A Faulty Solar Panel?
When faults develop with a solar panel the result is that these cells will heat up. This is because the energy generated by the electrons moving around is not flowing through the panel and onto the convertor, and must manifest somehow, it doesn’t can’t just disappear, so the energy becomes heat. This heat is what is detected when viewed with a thermal camera.
With multiple solar panels connected in series, when a fault develops in one panel it is likely to take down all the panels connected in the string, resulting in significant loss of energy generation.

Forest Canopy Survey Using Photogrammetry Techniques

Caterham School Photogrammetry of Forest Trees - Surveying for Chalara Fraxinea – Ash Dieback Last year, we were asked by Caterham School to survey and map their school forest known as Old Parks Wood. Ash trees within the wood were suffering from Chalara Fraxinea (Ash Dieback) a disease which has the potential to kill off 80% of the ash trees in the 45-acre wood and once dead, would quickly become dangerous to wildlife and other users of the woods, including the school pupils. The mission was to map the forest canopy by drone using photogrammetry survey techniques so that the school could get a full understanding of the degree of diseased trees that were present, and then subsequently put in place a management plan in conjunction with the Forestry Commission, Natural England and the local council. Project Background In 2014 the school had bought approximately 140 acres of Old Park Wood – partly to protect it from the threat of development but also to secure its long-term future as a bi...

Hidden Issues with Thermal Imaging During Building Surveys

Beyond the Surface: Discovering Hidden Issues with Thermal Imaging during Building Surveys Building surveys have evolved significantly, thanks to advancements in thermal imaging technology and the transformative impact of thermal imaging during building surveys, uncovering concealed issues that traditional methods might overlook. The Power of Thermal Imaging Thermal imaging enables a deeper understanding of a building’s thermal performance. By capturing infrared radiation, these cameras reveal temperature variations that are invisible to the naked eye. This non-destructive technique is particularly valuable for identifying hidden issues affecting a building’s efficiency and structural integrity. Harnessing thermal imaging technology during surveys provides a comprehensive overview of a building’s insulation, HVAC systems, and potential air leaks. This proactive approach goes beyond the surface, allowing for precise problem detection before they escalate. Unearthing Insulation Deficie...
