Raptor Maps partnered with FLIR Systems for a live 5-part webinar series on the use of thermal drones in solar inspections. The 5th part was a live Q&A webinar, the following summary of the questions asked and our answers can be viewed below. 

The first 4 parts of the webinar series are free on-demand videos discussing the following topics:

1. The Value of Adding Thermal for Solar Inspections

2. Thermal Drone Best Practices

3. Questions to Ask Before Hiring a Service Provider

4. Limitations of Thermal Drone Inspections

Part 5: Live Q&A Webinar

Below, are some of the questions we were able to get to with a summary of our answers given. 

What are some of the general uses of this technology in the solar space? 

There are many uses for thermal drones in the solar space. To start, when a solar farm is built doing a thermal inspection of it will confirm that the site was built correctly and the components are working properly. After that, either quarterly, semi-annually, or annually are also times that the solar PV system can be inspected. Doing this regularly will help the solar PV system be as productive as possible, allow you to know if the anomalies are warranty related issues, and make sure it reaches its full potential lifetime.  

What is the demand for drone companies in the solar industry?

There is a massive demand for drone companies performing thermal inspections on solar PV systems. In the last 6 months we have seen a sharp increase in the number of drone service providers entering the solar space because solar asset owners are demanding them. As the awareness of the benefits that using thermal drones in these inspections grows, more companies will look to adopt the technology in place of other inspection methods. 

One reason for the rapid growth is because currently a lot of solar PV systems are in uncontrolled airspace, allowing for drone service providers to be able to quickly and easily perform the inspection without having to go through regulations.  


At what size of a Solar PV system does an aerial solar inspection become valuable?

The answer to this is also very dependent on the age of the solar farm. For instance, a smaller but older solar PV site being inspected could bring considerable value to the ones receiving the report because as the PV systems age, the likelihood of anomalies occurring increases. We have found that anything over 100 kW, or roughly half an acre, is enough of a benchmark to see valuable results. The speed and accuracy that thermal drone inspections offer generates enough ROI to be chosen as the inspection method the next time an inspection is needed. 

For reference, one megawatt is roughly 5 acres in size. 


How does Raptor Maps train and qualify drone pilots, and how do I start a drone pilot program? 

For clarity, Raptor Maps does not offer a drone training program. We recommend going to well received places and using our, and FLIR’s resources on drone best practices. 

To start doing solar inspections, we recommend doing hands on drone training with your specific payload. You should take an in field drone training class. This will allow you to fully utilize the features of your equipment.
