Choosing solar monitoring software for a utility-scale plant is mostly a question of layers. Some tools collect and control plant data on site, some aggregate many sites in the cloud, and some act on the data once it arrives. This list compares well-known options for 50 MW to 1 GW portfolios by category and by the job each one is best at, so you can see which layer you are actually buying.
In short: ClearSpot is an AI and drone automation layer for utility-scale solar O&M. It works on top of the monitoring, SCADA and data acquisition systems listed below, adding autonomous drone inspection, AI fault detection, prioritised work orders and automated reports. It is not a replacement for plant SCADA.
What solar monitoring software does
At utility scale, monitoring usually covers three functions:
- Data acquisition and SCADA: on-site loggers, controllers and communications that read inverters, trackers, meters and weather stations, and in some cases control the plant.
- Portfolio monitoring: a cloud platform that collects data from many sites, calculates KPIs, raises alarms and produces reports.
- Analytics and automation: tools that explain losses, rank issues and push work to field teams.
Most portfolios need all three, often from different vendors. If you are looking for broader commercial and financial asset management rather than monitoring, see our separate list of the best solar asset management software in 2026.

Solar power monitoring software: tool-by-tool notes
ClearSpot
ClearSpot is an automated solar operations platform. It reads data from your existing monitoring and SCADA, combines it with autonomous drone solar inspection, and uses AI fault detection (99% fault detection) to identify, rank and assign issues. Customers target 30–50% O&M cost reduction, 65% downtime reduction and 97%+ availability.
AlsoEnergy PowerTrack
PowerTrack is AlsoEnergy’s monitoring software; AlsoEnergy has been part of Stem since 2022. Stem describes PowerTrack Software as an application for commissioning, monitoring, optimising and controlling clean energy assets, including data from third-party hardware. Stem also offers its own data loggers for the platform.
Power Factors Unity
Power Factors sells Unity, a renewable energy management platform. In October 2024 the company launched Unity APM, an asset performance management application covering multiple asset classes, including battery storage.
GPM Horizon
GPM Horizon is the cloud platform of GreenPowerMonitor, a DNV company, for managing multiple renewable plants across wind, solar and storage. It was launched by DNV GL in 2018 as a monitoring platform for wind, solar and energy storage.
meteocontrol VCOM
VCOM is meteocontrol’s cloud monitoring portal. Its documentation covers connecting data sources such as meteocontrol’s blue’Log data loggers, which feed plant data into the portal. To see how ClearSpot works alongside VCOM, read our ClearSpot vs meteocontrol VCOM comparison.
Trimark
Trimark Associates focuses on SCADA for utility-scale plants. In 2025 it announced True:SCADA, a control platform for utility-scale PV, battery storage and hybrid resources that integrates with ISO and utility protocols.
Huawei FusionSolar
FusionSolar is Huawei’s smart PV solution. Its utility-scale page lists string-level diagnostics through Smart I-V Curve Diagnosis. The system is built around Huawei inverters and the FusionSolar management platform.
Solar panel monitoring software vs module-level inspection
Most solar panel monitoring software works at inverter or string level. That is useful, but it cannot always tell you which module is cracked, which row is soiled or where a hotspot is forming. As we explain in why string monitoring alone is not enough, electrical data shows that energy is missing; inspection shows why.
This is the gap ClearSpot is designed to fill. Drone thermal and RGB inspection locates defects at module level, and ClearSpot links each finding to the monitoring data that shows its impact.
Choosing solar energy monitoring software for 50 MW to 1 GW
- Fleet mix: how many inverter, tracker and logger brands you run, and whether the tool handles all of them.
- Control needs: whether you need on-site SCADA and grid communications, or only cloud monitoring.
- KPIs: whether availability and performance ratio calculations match your contracts. See our guide to solar plant performance monitoring.
- Storage: whether hybrid sites need BESS monitoring in the same view.
- From alarm to action: how alarms become work orders, and how much manual triage remains.
- Reporting: how much analyst time monthly and lender reports still take. See AI solar performance reporting.
Where ClearSpot fits
ClearSpot is not another monitoring portal and does not replace plant SCADA. It sits on top of the tools above and handles the steps that usually stay manual: combining inspection and monitoring data, ranking faults, creating work orders and writing reports.
In one example, a 100 MW solar portfolio in India used ClearSpot to feed drone and AI inspection data and monitoring data into automated reports, cutting reporting and analysis time by 90%.
ClearSpot pricing runs from $50 to $1,000 per MW per year (platform subscription), depending on portfolio scale, site size and the depth of automation and monitoring.
Frequently asked questions
What is the best solar monitoring software for utility-scale plants?
It depends on the layer you need. SCADA and data acquisition tools such as Trimark handle on-site data and control. Cloud platforms such as PowerTrack, GPM Horizon, meteocontrol VCOM and Power Factors aggregate portfolios. ClearSpot adds AI and drone automation on top.
Does ClearSpot replace SCADA or other solar monitoring software?
No. ClearSpot reads from your existing SCADA, DAS and monitoring platform. It adds drone inspection, AI fault detection, prioritised work orders and automated reports.
What is the difference between solar monitoring software and asset management software?
Monitoring software collects plant data, calculates KPIs and raises alarms. Asset management software also covers contracts, finance and portfolio decisions. Many vendors offer both.
Can I use inverter-manufacturer portals for a mixed fleet?
Manufacturer portals such as Huawei FusionSolar are built around that manufacturer’s equipment. For a mixed-brand fleet, check each portal’s third-party device support or add a vendor-neutral monitoring platform.
Why add drone inspection to solar monitoring?
Monitoring shows that energy is missing at inverter or string level. Drone inspection finds the module-level cause, such as cracks, hotspots or soiling.
How much does ClearSpot cost?
Pricing runs from $50 to $1,000 per MW per year (platform subscription), depending on portfolio scale, site size and the depth of automation and monitoring.
