Solar Plant Failure Detection

SunSpotter

SunSpotter is solar fault detection software that monitors your PV system in real time, using your existing data to spot hardware issues immediately.

It catches power-robbing failures early to boost energy production and minimize downtime.

Easily integrated into your current setup, SunSpotter ensures your solar plant runs at peak efficiency.

Remote locations make regular inspections of solar sites difficult and infrequent. As a result, broken equipment often goes unrepaired, causing large solar plants to underperform. Our recent analysis shows this results in a 2% annual energy output loss.

Operators miss key performance goals and fail to meet energy commitments due to these losses. Much of this lost output could be avoided with better maintenance practices. The problem? Traditional methods—manual inspections and drone flights—are slow and expensive. Even traditional data-driven M&D, used extensively in fossil fleets, overwhelms operators with false alarms when applied to PV. As a result, solar plants run below their potential, losing power and revenue every day.

SunSpotter changes the game.

Here’s how:

  1. Boosts efficiency: Remote monitoring gives operators real-time insights, so they can fix problems faster and keep the plant running smoothly.
  2. Cuts costs: It uses the data you already have, which means no more expensive on-site inspections or drone flights.

Our monitoring system does the heavy lifting for you. It monitors your equipment 24/7, detecting twice as many failures while sending fewer false alarms, so you can focus on what really matters.

 

Benefits

  • Continuous Fault Detection

SunSpotter continuously monitors your plant using your existing data. It detects DC hardware faults like string outages and tracker issues. By catching these faults early, SunSpotter pinpoints the exact hardware that needs repair, enabling faster fixes and boosting power generation. Our proprietary algorithm identifies twice as many faults as leading tools while reducing false alarms.

  • Automated Setup and Seamless Integration

SunSpotter quickly identifies your plant’s layout using site data samples, streamlining setup. It seamlessly integrates with your existing PV monitoring systems, with no need for extra sensors or hardware.

  • Real-time Anomaly Detection

Forget slow, costly inspections. SunSpotter analyzes your PV data in real time, identifying specific DC hardware faults as soon as they happen, helping you avoid inefficiencies and boost energy output.

  • Reduced O&M Costs

SunSpotter tracks faults and power loss in real-time, giving you immediate insights to prioritize issues, reduce downtime, and schedule maintenance efficiently. You can focus on what matters most—fixing critical problems first.

  • Proven Results

SunSpotter originated from DOE-funded research and has been validated on over 1GW of installed PV capacity. This product was the result of collaborative research performed by the Electric Power Research Institute, Inc.
