Reducing the Cost and
Complexity of Solar Monitoring


Locus Energy’s Data Acquisition System (DAS) solutions combine plug-and-play data acquisition hardware with industry-leading cloud-based software, the Solar-OS™ solar monitoring platform. Locus Energy offers DAS solutions for the residential, commercial and utility-scale PV markets, providing operational transparency on system performance through an intuitive and powerful user interface.

For residential and light commercial PV monitoring, Locus Energy offers, respectively, the LGate 120 and 320, which feature:

  • Low-cost digital socket meters with integrated cellular uplink to significantly reduce networking and commissioning complexity
  • Advanced firmware with compression algorithms to minimize cell data costs
  • RS-485 inputs for direct communication with inverters and other devices


For large commercial and utility-scale PV monitoring, Locus Energy offers the LGate 360 featuring:

  • Plug-and-play connectivity with a wide variety of inverters, meters, weather stations and other third-party equipment
  • Flexible networking options to reduce conduit runs and minimize hardware costs
  • Options for integration with leading SCADA equipment for command and control applications

Driving Operational Efficiency
for Solar Asset Managers

As the rate of solar adoption grows, operators of PV fleets are looking for more sophisticated tools to manage assets and track performance of portfolios. Locus Energy’s SolarNOC™ is a cloud-based enterprise asset management platform for fleets of residential, commercial and utility-scale solar PV systems. The SolarNOC™ allows fleet managers to aggregate performance data from many sources, apply advanced analytics and streamline operations and maintenance activities.  Key features:

  • Data aggregation from multiple hardware stacks, 3rd party data feeds/APIs and legacy monitoring providers
  • Powerful filtering interface to granularly track asset data and create role-based dashboards with a variety of KPIs/diagnostics
  • Integration with key 3rd party enterprise applications for improved workflows




Big Data for Solar: Providing Insight Into Distributed PV Assets


Monitoring systems can tell you that a system isn’t meeting performance expectations, but they can’t tell you why. Until now. Locus Energy’s PVIQ Suite™ is a powerful set of analytic and diagnostic tools allowing fleet operators to assess performance at both the system and fleet level and then drill down into the specific causes for a system’s deviation from expectations.  Key features:

  • Highly accurate and granular satellite-derived irradiance data with coverage across the continental US
  • Advanced algorithms automate the identification of the root causes of system underperformance
  • Spreadsheet plug-in connected directly to the Locus Energy database
