Locus Energy’s PVIQ Suite is a set of performance optimization tools that provides fleet managers with a much-needed means of evaluating how the actual performance of solar PV assets ranks against expected performance by identifying specific performance drivers. Such data is invaluable — not only for system stakeholders who can use it to identify and rectify problems, but also for financial institutions, which can use the PVIQ Suite as a means of ranking the value of solar PV assets. The PVIQ suite consists of three elements: Virtual Irradiance data, Performance Waterfall Analytics and a spreadsheet plug-In tool.
Virtual Irradiance (VI)
As the “fuel” for solar PV systems, solar irradiance is the most valuable data for assessing the performance of a solar PV system. But the ability to compare actual performance to expected performance is limited by the cost of acquiring granular irradiance data for a specific location. Using data from the 40,000 Locus Energy sensors across the country, as well as private and public historical and real-time data from weather stations, satellite imagery, federal agencies and other sources, Locus Energy’s proprietary algorithms can provide highly accurate, ground-level irradiance data across an install base or a geographic region on a 15-minute basis, thus eliminating the need for costly on-site sensors. When used with other modeling data — i.e., the type of panel or inverter — Locus Energy’s VI tool provides system stakeholders with a truly accurate assessment of how much energy their systems should be producing based on the amount of sunlight that is hitting the ground.
PVIQ Excel Datalink
PVIQ Excel Datalink is a Microsoft® Excel® add-in which establishes a direct link between the Locus Energy database and Excel workbooks. PVIQ Excel Datalink leverages the company’s robust API to retrieve and display a variety of data within a spreadsheet. Users can quickly create custom reports and analyses leveraging Excel’s advanced data analysis functions such as macro automation, conditional formatting and pivot tables. With the PVIQ Excel Datalink, fleet managers can now spend more time on asset optimization and less on routine operational reporting.
The add-in is packaged with a set of template reports that may be customized to each user’s needs. With PVIQ Excel Datalink, users can supply data to any performance model they prefer, or draw modeled performance calculations directly from the platform, thus providing all the flexibility users need in order to accurately model PV assets.
Benefits of PVIQ Excel Datalink:
- Significant time savings in regular reporting by eliminating manual download of data into spreadsheets.
- Enable automation of custom analyses
- Reduction in manual errors while copying and manipulating data.
- Quick access to all device data, analytic data like Virtual Irradiance, performance data, and system metadata/registration data for analysis.

Using a range of algorithms and empirical models, PVIQ’s Waterfall report can remotely determine the root causes of a solar PV system’s failure to meet performance expectations. These reasons may include factors such as weather uncertainty, snow downtime, shading, equipment downtime, equipment degradation and inverter problems. The prescriptive analysis provided by Waterfall enables a specific, detailed understanding of which factors are most affecting the performance of a solar PV system and how the causes of the underperformance can best be addressed.
