Locus Energy has launched the LGate 120 and 320 -- its next generation of smart meters designed to allow solar installers and asset managers to more easily collect, monitor and analyze performance data from both residential and light commercial solar PV systems.

Together with Locus Energy's web-based SolarOS monitoring platform, the new meters enable solar fleet operators to efficiently gather data for troubleshooting, asset optimization and performance guarantee/billing functions.

Until recently, cellular socket meters available for PV monitoring have been mainly repurposed utility meters, which have focused on consumption and demand as opposed to the PV industry's requirements. Locus Energy reports that the LGate 120 and 320 are the first cellular smart meters designed specifically to measure the performance of PV installations. Both units can communicate directly with inverters to collect additional AC and DC data points as well as fault code information, which is key to lowering O&M costs over a fleet of systems. In addition, the new meters can plug directly into local area networks via Ethernet when the cellular signal is not strong enough at a given location.

Locus Energy is out with a new product that expands solar monitoring capabilities.

Innovation is rare in the solar PV monitoring space, where the difference between competing products is often based on detailed features and functions, leaving the impression that all solutions are very similar. But the latest product announcement from Locus Energy has made a big splash and may change the game in the U.S. residential PV monitoring market.

In other words, so far U.S. PV system owners and operators have had to choose between Locus, a feature-rich metering and monitoring platform with reliability issues due to its dependency on the homeowner’s network, or another monitoring platform based on Itron, a highly reliable cellular metering solution with limited data and little troubleshooting capability. The Lgate 120 product announced by Locus today seems to resolve this dilemma.

The new Lgate 120 could lead the way for a new generation of residential PV metering and monitoring hardware for solar leasing and power purchase agreement firms.

A waterfall of data could cut solar O&M costs.

“What is unique about our service,” explained Locus Energy VP Adrian De Luca, “is that we take that data and combine it with proprietary analytics.” Computer screen dashboards that monitor renewable energy systems and report field data are now commonplace. Locus Energy believes it has an edge there.

“Virtual irradiance,” said De Luca, “is a calculation engine that runs every fifteen minutes and will tell the user how much sunlight is hitting the ground anywhere in the continental U.S. with a one-kilometer-by-one-kilometer resolution.”

“What is different about the Locus formula,” he explained, "is that every five minutes, as we get a reading from the field, we also generate an identical value for expected performance, and so there is a constant true-up of what happened and what should have happened.”
