Andrew Greenfield checks his home’s solar power output against consumption through his computer and mobile phone dozens of times each day. The IBM (IBM) storage engineer enjoys trying to match the power he consumes to heat his pool in Arizona with what he produces during the day from the panels on his roof.

The same rooftop solar providers that are threatening utility revenues are more than just occupying customer roofs—they’re inside the home, monitoring usage trends and adapting the systems to meet both the homeowner’s needs and their own bottom lines.

SolarCity, Sunrun, SunPower (SPWR), and Locus Energy are amassing billions of points of data in smart home systems that consumers love and that baffle utilities, many of which have no incentive to help consumers manage their power usage more efficiently.

“We have an algorithm that tracks the clouds designed by a Ph.D. from Stanford,” says Adrian De Luca, vice president in charge of sales at Hoboken (N.J.)-based Locus Energy, which monitors more than 25,000 solar systems in the U.S. and Canada. “We can tell from across the country whether performance isn’t up to specifications for whatever reasons,” De Luca says. “The utilities should want this data.”

Nearly 12,000 solar professionals gathered last week in Chicago at Solar Power International. Through conference sessions, trade show exhibits and networking events, it was clear that this industry overcome challenges and is now gaining traction. In the opening session, Rhone Resch, President and CEO of Solar Energy Industries Association said “Welcome to the big leagues.”

With all the various types of monitoring systems, the industry has moved well beyond the why and how of solar and is now examining exactly what is happening with specific installations. AlsoEnergy recently acquired Deck Monitoring and announced that it will continue with both product lines targeted at commercial and utility-scale PV. Skytron’s solution goes beyond operations and management (O&M) of PV plants and into what Murad Can, Vice President Global Customer Operations at Skytron calls “energy efficiency management,” using algorithms for diagnosis and control. Santerno is an Italian O&M company that introduced PV Power Plant Controller that offers remote control on-web diagnostics. And Locus Energy provides residential solar monitoring solutions up to customized dashboards for managing fleets of solar assets.

As we’ve written before, solar monitoring is an absolute must for any new solar installation. Now Locus Energy has given installers two new options to do just that.

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.

A technology company with Investor’s Circle backing was just acquired by an energy software firm.

Locus Energy, a New Jersey-based technology firm that monitors solar panel performance and provides data analytics was acquired by Kentucky software firm Genscape.

Investor’s Circle, which has its headquarters at American Underground in downtown Durham, first saw Locus entrepreneurs presenting at an event four years ago in Philadelphia.

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.”
