As a solar professional, it’s important to carefully consider the photovoltaic (PV) design that will generate the highest return on investment (ROI). While the specifics may differ between residential and commercial systems, the themes are almost always the same: fast install and fast payback. Greg Smith, Senior Technical Trainer at SMA America, explores the ways that PV systems can be optimized to increase return on investment.

Locus Energy, a solar monitoring and data analytics platform provider for the solar photovoltaic (PV) market, has announced that the number of systems under Locus management has surpassed 50,000 installations and is quickly approaching 1 GW in capacity, reflecting the company’s leadership position with developers, owners and operators of residential, commercial and utility-scale solar PV fleets.

Locus Energy, based in Hoboken, New Jersey, now manages one of the nation’s largest solar performance data sets, processing over 15 million data points daily for a cumulative total of more than 30 billion data points. This wealth of solar data provides the foundation for Locus’ high quality fleet management and advanced analytics solutions.


Locus’ DAS hardware and fleet management software are now being used at more than 50,000 sites by more than 500 customers including asset managers, engineering, procurement and construction (EPC) contractors, project developers and O&M providers. In the residential market, Locus has been named the nation’s largest independent solar monitoring provider for two consecutive years.

The 50,000 site milestone is a result of 5 consecutive years of over 100 percent growth, led by customer demand for its SolarNOC (Network Operations Center) enterprise-grade software, which allows system owners, operators and investors to more easily and cost-effectively collect, monitor and analyze real-time performance data from large fleets of solar assets, as well as its flexible and innovative data acquisition systems (DAS) solutions.

In addition to its rich feature set, flexible line-up of DAS hardware and its SolarNOC fleet management software, Locus now offers a suite of analytics tools called PVIQ that provides real-time intelligence on solar performance, allowing owners and operators to easily identify which systems are not performing up to expectations and the reasons behind that underperformance. The PVIQ analytics suite is a set of advanced data analytics tools that enables owners and operators to efficiently analyze performance. It is comprised of three elements: the Virtual Irradiance (VI) tool, the Waterfall performance report and a spreadsheet program plug-in that allows users to access the Locus database directly, dramatically reducing the time required to prepare periodic performance reports.

“Locus’ strong growth is a testament to our focus on the solar market, and meeting its evolving needs in terms of distributed fleet management at scale,” said Michael Herzig, CEO at Locus Energy. “As the rate of solar adoption has grown, our products have become increasingly important to fleet owners and managers in their mission to increase efficiency and reduce O&M costs.”

“Solar electricity is entering the mainstream, with predictions being that it will be cost competitive with traditional electricity in many states before the end of the decade,” Herzig continued. “As the share of the U.S. electricity supply represented by solar continues to grow, Locus will be there to provide the industry with the sophisticated tools required to maximize electricity yields and minimize the costs of operating large fleets of residential, commercial and utility-scale systems.”
