Independent verification for solar fleets

Prove what your solar fleet did, and know what to do next.

Monitoring alone is not evidence. The record can be wrong, buried in the numbers or missing altogether, and piecing it together by hand delays action.

Trackable checks every solar site against the revenue meter, and where the records can’t settle a question, against its own instrument on site. Read-only, alongside your monitoring.

  • What each site did and why, every outage on the record with how it began
  • Which fixes pay the most, ranked, with scenarios to test them
  • How every inverter is running, checked each night

Where Saltbush Mesa's missing energy went

Since May 2022 the revenue meter recorded 14,983 MWh, 687 MWh (4.4%) short of the P50 forecast. In the weather it had, the site lost 648 MWh on site or in its records.

Long outages: grid trip, daytime restartInferred

Open: rests on records still requested. What the data shows so far:

5 of 6 outages of six hours or more began with every running inverter tripping on grid protection, and all 6 ended between 7 am and 5 pm. What was reset each time is still an open question.

A measurement would settle this: in the monitoring’s readings every unit stops at once. Trackable’s instrument times each inverter’s trip to the millisecond, so the record shows whether the utility or the site’s own switchgear went first.

The gap

Monitoring reports what the equipment says about itself. Nothing independent checks it.

Piecing it together by hand delays action, and at refinancing or sale an unverifiable history is priced against you.

Wrong.

A mislabeled sensor or a dropped data link skews a site's numbers for years.

Buried.

Losses hide in readings too coarse or too scattered to see.

Missing.

Outages no service record explains, and gaps nobody filled.

Picture a marathon runner. Check the pulse every few minutes and the race looks steady. Wear a heart monitor the whole way and you catch the falter at mile nine. Your monitoring checks in. Our instrument never looks away.

Case study · a real 1 MW community solar site we audit · 2026
EXHIBIT 01
Every outage over six months, timed and classified from the meter and the inverters' fault registers.
EXHIBIT 02
By the fault registers alone, every one looks like a grid-protection trip, with no inverter fault.
EXHIBIT 03
Our independent measurement matched the site's production meter to within a fraction of a percent, month after month.
EXHIBIT 04
One was actually an on-site failure, by the O&M technician's assessment. Its fault codes look exactly like a grid trip.
EXHIBIT 05
About $10,500 a year in power lost to site outages, averaged over the site's full record since 2022. Nineteen in twenty of those dollars were lost in outages missing from the service records.

Outages that look alike in the monitoring can begin in very different places. We show where each began, what it cost, and which records settle who pays.

What this means for an owner

Know where it went

The weather separated from what happened on site, month by month, so you can act on the part that’s yours.

Recover lost revenue

Fixes ranked by what they’re worth, with scenarios to test each one first.

Back up your history

Where service records are silent, show a lender or buyer when each outage began and ended.

EVERY FINDING CHECKABLE BY THE OWNER, THE OPERATOR, OR THEIR ENGINEER, WITHOUT REFERENCE TO US.
The portal

Every site's record, in one place.

Updated every night and checked against the revenue meter. The owner, the O&M provider and the monitoring provider each see the version written for them.

From Trackable Systems <alerts@trackable.systems>Subject Saltbush Mesa Solar: 2 new findings, Jul 21
Trackable

2 new findings

Trackable's daily check of Saltbush Mesa Solar found 2 new things worth a look on Tuesday, July 21.

  • Inverter 1-7: Produced 71% of what its neighbors did, per kW of panels
  • Inverter 1-10: No readings in the monitoring all afternoon, but the production meter shows it kept producing (a data link problem, not lost energy)

Based on the monitoring's 15-minute readings and the production meter. We email each condition once, not every day it lasts.

Why it holds up

Every claim can be checked, by your engineer or your buyer’s.

Your engineer can check every claim, and your buyer's engineer can reproduce every result. And the record gets sharper with every event, every answer and every site.

Built for funds and IPPs with distributed C&I and community solar.

  1. Records from every roleThe portal asks the owner, the O&M provider and the utility for what only they hold. Each answer is reviewed, then the record updates.
  2. An evidence packet for every outageThe original files, every fault code decoded, and a fingerprint on each file that proves nothing changed.
  3. Locked and sealedEvery reading is kept for seven years, and our instrument's recordings are sealed each hour on the Base public blockchain.
  4. Open until settledA finding that rests on a record still requested says so, and names the record that would settle it.
  5. Our own signature libraryEvery disturbance our instrument catches is catalogued each night with its waveform shape, beside what the monitoring showed at that moment, so a pattern that keeps coming back stands out sooner. The library grows with every event.
What we do

Four levels of proof. Start at any of them.

Every level includes the portal and its record of each site. Choose a single pass or a record kept current every day. Then choose whether we work from your monitoring alone or add our instrument on site.

MONITORINGREVENUE METERSERVICE LOG ONE RECORD
Levels 1 and 2 · No hardware on site

Make sense of the data you already have

Start here when the question is what your records can prove. We read your monitoring data, test it against itself and the revenue meter, and say what it shows and what it cannot.

INVERTER NODE 960 READINGS A SECOND
Levels 3 and 4 · Our instrument on site

Add independent, high-fidelity measurement

Add this when you need to know, and prove, the true health and performance of each site. Our instrument measures each inverter directly, independent of your monitoring, and catches what happens between its readings.

LEVEL 1ONCE

Forensic screen

The first pass through every site's records, in about 30 days for a 30-site fleet. Your team's part is small: read-only access to your monitoring platform, and four documents if you have them: the service log, the P50 energy report, the as-built single-line diagram and the price per kWh. Nothing missing holds us up; a finding that needs a document says so until it arrives.

You get: which sites' data can be trusted, every outage timed and classified, what each site's losses are worth, and a clear next step for each one, all in your portal with every finding linked to the records behind it.

LEVEL 2EVERY DAY

Continuous intelligence

Monitoring for your monitoring. Keeps the portal current every night. New outages go on the record as they happen, alarms come decoded, and each month's gap to forecast is explained.

LEVEL 3ONCE

Instrumented site audit

Adds our instrument for an audit period. It records each inverter 960 times a second, more than 280,000 times the detail of the monitoring's five-minute readings, checked against the revenue meter. The findings go into your portal. It settles what the site actually does.

Settles: who opened the breaker, whether a quiet inverter was producing, which units ran while the monitoring was dark, and why the site waited to restart.

LEVEL 4EVERY DAY

Continuous intelligence, instrumented

Our instrument stays on site, and the portal stays current every day. The cause of each trip is on the record, not inferred, and the performance number comes without the data-quality caveat.

Start

Start with a free Fleet Health Check.

The Fleet Health Check reads the monitoring data you already have and ranks every site by where verification would matter most, and why. One week, read-only, yours to keep. It is a free first look. Level 1, the forensic screen, is the full version.
