The global solar industry has reached 2 terawatts of installed capacity. Yet across that installed base, a systematic bleed is happening. Solar sites are underperforming at rates that would be unacceptable in any other infrastructure asset class.
In 2024, the industry lost $5,720 per megawatt to equipment failures and operational inefficiencies. For a 100 MW site, that translates to $572 million in lost revenue over its operational lifetime, a figure that dwarfs the cost of prevention.
The problem is not new. What is new is the scale. As solar deployments have grown, the gap between expected and actual performance has widened. Sites are losing 5.77% of their potential output to equipment-related issues. This is a structural problem that compounds over time.
The industry knows where the losses are coming from. Inverters account for 43% of all solar system failures and 36% of lost energy production.
String failures, combiner box issues, and tracker malfunctions make up the rest. Yet these problems persist because they are not visible until they become catastrophic. A single inverter failure on a large site can cost $50,000 to $100,000 in lost revenue before it is even detected.
For asset managers and operators, the question is not whether to address underperformance. It is how quickly to address it. The cost of early detection and intervention is a fraction of the cost of allowing failures to compound.

A site that catches an inverter issue in month two instead of month six recovers tens of thousands in lost revenue. A site that prevents tracker failures through predictive maintenance avoids the cascading power losses that come when tracking systems fail.
The technology to detect these issues exists. Thermal imaging, string-level monitoring, and AI-powered anomaly detection can identify problems before they cause revenue loss. The gap is not in technology. It is in adoption. Many operators still rely on monthly production reports to identify issues, a lag time that means months of undetected losses before action is taken.
For solution providers, this is the market opportunity. Sites are losing billions because they lack real-time visibility into equipment health. Companies that can provide that visibility, whether through hardware, software, or hybrid solutions are solving a problem worth billions in recovered revenue.
