Professional and cost effective solar farm inspections


Solar power is a relatively new and increasingly important source of electrical energy for business owners, utility companies, and homeowners alike.


To ensure any energy system is performing as expected it needs periodic inspections. Solar PV systems are not exempt from this requirement.


Infrared thermal imaging technology offers an efficient and accurate way to spot damaged solar cells, even in large arrays.


Why schedule an inspection?


Our approach


We use a specially modified survey vehicle to speed up the solar panel inspection process and help keep costs down. We can either work with a retractable mast or the vehicle is designed with a platform for a second person to scan and photograph as we move along. Our approach offers ground level inspections along with a spatial analysis; consequently clients can gain a quick overview of the site and have the advantage of close up inspections. Faulty/damaged panels are subsequently marked with a red paint pen or sticker for ease of identification making it helpful for the maintenance team.


What can you find?

What shows up on a thermal image includes cracked cells, poor tabbing soldering, poor header bar soldering, faulty diodes, moisture penetration, shading and bird droppings all of which affects the performance of the module. The problem is they all have a larger or lesser impact depending on the degree of resistance caused by the poor connections. A poor module in any string of modules can have a major impact on the overall energy generation performance.


Heat Tight can spot these problems through a comprehensive solar power scan. We look at all aspects of a photovoltaic system, from cells to combiner boxes and inverters. Solar panels need maintenance like any other piece of equipment and infrared is an efficient and cost effective way to keep the system operating at its best.


What information is provided?

Each thermographic image taken during our inspections of solar farms and commercial roof tops would provide the following details:




Solar PV Inspections - Homes

We can also provide inspections for domestic homes which will be conducted with the use of a telescopic mast. Inspections here will be imaged from the front elevation only.
