As the longest day of the year approaches, solar systems are entering their peak production season. But summer heat doesn’t just boost solar output. It can also reveal hidden issues that threaten system performance and efficiency. That’s why this is the ideal time to schedule a solar drone inspection.
At CES, our aerial thermal imaging services give you an in-depth, real-time look at how your system is performing under stress when solar panels are working their hardest.
More Sun, More Stress
During summer, high irradiance levels mean your solar panels are operating at or near maximum capacity. But the increased thermal load can exaggerate minor issues and cause new faults to emerge. That’s where drone-based inspections shine.
Flying above your array, our drones use high-resolution thermal sensors to detect:
- Hot spots that indicate failed cells or internal shorts
- Uneven heating that signals soiling, shading, or degradation
- Anomalies in strings or modules that might be invisible during cooler seasons
By capturing data when the system is under full load, we get the clearest picture of what’s working, and what isn’t.
What Thermal Imaging Really Shows Us
Thermal imaging isn’t just a heat map; it’s a diagnostic tool. Our trained technicians interpret the data to uncover performance reducing issues, including:
- Microcracks and delamination – These can start small but grow with heat cycles, reducing output and posing fire risks.
- Reverse polarity or internal short circuits – These are safety-critical issues that often surface during peak operation.
- Underperforming strings – A single compromised module can affect the output of an entire string — especially on hot, high-production days.
- Combiner box and junction faults – Abnormal heating in electrical enclosures can point to wiring or connection failures.
With thermal imagery captured by drone, we’re not just spotting problems. We’re pinpointing exact locations, so maintenance teams can act fast and efficiently.
Take Action Before the Heat Takes Its Toll
Regular drone inspections, especially in summer, help extend the lifespan of your solar system. By addressing faults early, you can prevent expensive downtime, protect equipment warranties, and ensure your system performs at its best during the sunniest months of the year.
And because inspections are performed by drone, there’s no need to disrupt operations or put personnel at risk. It’s fast, safe, and incredibly effective.
Your System Is Talking, Are You Listening?
Summer solstice is more than just a calendar date. It’s a performance milestone for your solar investment. Let CES help you tune in with a thermal drone inspection that tells the full story from the panels to the power output.
