In recent years, the growth of utility-scale solar energy systems has been on the rise as more and more companies and organizations turn to renewable energy sources to meet their power needs. However, this growth comes with an increased demand for asset managers to keep these facilities maintained and performing at peak efficiency. To mitigate system-wide degradation and failure a proper plan needs to be utilized at each facility.
"There’s been a huge amount of growth in utility scale solar applications for large companies, as they’re starting to see the benefit of large solar projects purchased through leases, which is causing the market to realign."
In this article, we will examine the growth of utility-scale solar systems, their unprecedented degradation rates, and the importance of ensuring long-term performance with aerial drone thermography. We will also explain why drone thermography for inspections and maintaining solar PV facilities is the best-suited option for utility-scale systems.

The Growth of Utility-Scale Solar
As the global supply chain issues have started to ease the growth of utility-scale solar energy systems has continued to increase. According to the International Energy Agency (IEA), more utility-scale solar has been installed in 2021–2022 than all other forms of energy combined. This is a clear indication of the growing demand for renewable energy sources and the increasing importance of utility-scale solar for future power needs around the world.
"Solar PV is becoming the lowest-cost option for new electricity generation in most of the world, which is expected to propel investment in the coming years."
There are several reasons for this tremendous growth in utility-scale solar. One of the main drivers is the decline in the cost of solar technology and required components, making it more affordable and accessible for companies and organizations of all sizes. Additionally, governments around the world are implementing policies and incentives to promote the use of renewable energy sources, further driving the growth of utility-scale solar.

Unprecedented Degradation Rates
One of the many challenges utility-scale solar systems face is the increasing rate of system degradation to the solar facility as their systems age. Degradation of utility-scale solar systems refers to the decline in performance or functionality of the system over time. This can be caused by a variety of factors, including poor design and installation, exposure to harsh environmental conditions, and inadequate maintenance.
"Newer utility-scale solar PV plants are holding up better to degradation than their predecessors. Overall, the average utility-scale solar PV was found to experience a performance loss of -1.23%/per year. Plants built since 2014 have declined in performance less (-1.1%/per year) than plants built before 2015 (-1.2%/per year)."
Some examples of degradation in utility-scale solar systems include:
- Decrease in power output over time, leading to a reduced ability to generate electricity.
- Damage to the solar panels, such as cracking or discoloration, which can reduce the efficiency of the system.
- Issues with the inverter or other electrical components, which can result in system failure or reduced performance.
- Corrosion or damage to the mounting structures or other hardware, which can compromise the structural integrity of the system.
As systems continually degrade over time these issues can have a significant impact on how asset managers meet their energy production goals for their customers. Degradation can also increase the risk of system failure, which can be costly if repairs require a facility shut down to complete. Therefore, it is crucial to employ effective and efficient PV inspection and maintenance techniques to ensure the long-term performance of these systems.

Ensuring Long-Term Performance of Utility-Scale Solar
Maximizing the long-term performance of a utility-scale PV installation is crucial for asset managers that rely on these systems to meet their energy production goals. Drones are the most effective way to extend the lifespan of these systems. Drone-based aerial thermography is growing rapidly for these types of inspections because it can provide detailed, real-time analytical data on the temperature of different components of the system. Drones can save time and reduce costs compared to traditional ground-based inspections, access hard-to-reach areas, such as rooftops and remote sites, and provide detailed images that can be used to identify and diagnose issues such as shading, soiling, or damage to the panels.
