Use case · worked example

The output is the proof.

String 14B at a solar farm is making 18% less than its neighbours. Teleport sends a drone to look, then the right fix: a cleaning robot for dirt, a licensed technician for a hot spot. Nobody is paid on a photo. They're paid when the string's own meters show the power is back.

Talk to usAll use cases
String 14B, fixed and proven by its own outputFive rows of solar panels from above. String 14B is dusty and falls to 82 percent of its neighbours. A drone lifts off its pad and flies a thermal pass along 14B. The finding is soiling, so the branch to the cleaning robot is taken and the branch to a licensed technician is not. The robot runs the length of the row and the dust clears. The output bar climbs back to 99 percent of its peers. Three checks tick: the robot ran 14B, two hours of measured clear sky, at least 97 percent of peers. Verified, and a receipt prints: output 99 percent, paid on accept.14A14B14C14D14EDRONE PADFINDINGHOTSPOT → LICENSED TECHSOILING → CLEANING ROBOTSTRING 14BWATCH · 2 H−18% VS PEERSPEERS14B82% OF PEERS99% OF PEERSCHECKSROBOT RAN 14BCLEAR SKY · 2 H≥ 97% OF PEERSVERIFIEDOUTPUT 99%PAID ON ACCEPT

§ 01

One string is quietly 18% down.

Solar faults don't announce themselves. A dirty row or a hot cell just makes less power, all day, until someone looks. The plant's meters notice first.

Who asks
The plant's monitoring system spots the drop. The owner's operations agent posts each task under a mandate, and the owner answers for every one.
Who does it
A drone looks. A cleaning robot cleans. A licensed technician replaces panels. Each one only when the step before calls for it.
Evidence only
The string inverters, with signed meter readings, and an irradiance sensor that says whether the sky was really clear.
Evidence
Thermal images and a flight log, the robot's run log, the technician's capture on site, and the meters.
Who pays
The owner, step by step: $60 for the drone, cleaning by the run, $280 for the technician plus the panel. Example figures.
You get
A string back to full output, and a proof that says so in kilowatts, not adjectives.
Example · photo to come

A photo shows a clean panel. The meter shows it's making power again.

The short version

A device asks, an agent decides, and a drone, a robot or a person does the work, each picked by what the step before it found. Every fix is checked the same way: by what the string produces once the sky is clear.

Helios Flats and string 14B are fictional. Prices are illustrative.

§ 02

The finding picks the fix.

The drone doesn't fix anything. It finds out what's wrong, and that finding decides who goes next: a robot for dirt, a licensed technician for a hot spot or a cracked panel. Every branch ends at the same check.

In this example the finding was a hotspot, so § 04 and the receipt follow the technician's branch. The hero above follows the cleaning robot's.

§ 03

From a dip on a chart to power back, in six steps.

Cheapest look first, then the fix the finding calls for. One workflow per string, from the first alarm to the last release.

  1. 01

    Detect

    String 14B runs 18% below its neighbours for more than two hours of measured clear sky. The watch order fires once, for this string.

  2. 02

    Look

    A drone flies a thermal pass over 14B. It doesn't fix anything. It comes back with a finding: soiling, a hotspot or a crack.

  3. 03

    Branch

    The finding picks the next task. Dirt goes to the cleaning robot. A hotspot or a crack goes to a licensed technician, with the panel as goods.

  4. 04

    Fix

    The robot runs the row. Or the technician locks out the string and swaps panel 14B-07.

  5. 05

    Verify by output

    Over the next two hours of clear sky, 14B must be back within 3% of its neighbours, on signed meter data.

  6. 06

    Hold back

    For a panel swap, 85% is paid on accept. The last 15% follows after seven days with no repeat.

§ 04

Paid on kilowatts, not photos.

A clean-looking panel can still be broken. The string's own meters settle it: back within 3% of its neighbours, over two hours of measured clear sky, and still there a week later.

The model only reads the thermal image to pick the branch. It never decides whether the repair worked: the meters do, under a versioned policy.

§ 05 · Electrical safety

Live strings, licensed hands.

A string in sunlight is live. The drone and the robot never touch anything electrical. Panel swaps go only to a technician with a checked licence, and only after the string is locked out, tagged and measured dead, all of it recorded before the first bolt comes out.

§ 06

What needs care.

Measuring power is easy. Measuring it fairly, on the right day, around live equipment, takes a few rules.

  • Clouds aren't failures

    A cloudy afternoon looks like a failed repair, and a sunny one can flatter a bad one. Clear sky is measured by an irradiance sensor, not assumed.

  • Live strings, licensed hands

    A string in sunlight is live, isolator or not. Electrical work goes to licensed technicians only, after lock-out and tag-out, and never to the marketplace.

  • One string, one alarm

    Output wobbles. The watch order fires only after two hours of clear-sky deviation, and only one workflow can be open per string at a time.

  • The panel is goods

    Hardware is billed separately from labour, so a $280 repair and a $200 panel never blur in the proof. Warranty swaps are tracked the same way.

  • Drones fly by the rules

    The pilot's certification is a checked capability, and airspace rules are checked before the flight. The drone looks. It never touches.

  • A different fault is a new task

    If 14B drops again for another reason, that's a new workflow with its own finding, not a clawback from the technician who fixed the last one.

§ 07

A receipt measured in kilowatts.

The owner gets a proof per fault: what the meters saw, what the drone found, who fixed it and what the string made afterwards. Rolled up, it's a quarter's worth of uptime a lender can check.

Dollars pay the technician, part now and part after the week holds. Nobody needs $PORT to post a repair or get paid for one.

For builders.

A WATCH standing order on the string, an escalation that branches on FINDING:SOILING or FINDING:HOTSPOT, and a MEASUREMENT condition on ATTESTED_DEVICE meter data, so the proof can reach the top assurance level.

Proposed additions this use case surfaced

Findings that branch
An escalation that picks its next template from the finding: FINDING:SOILING to the robot, FINDING:HOTSPOT to a licensed technician, each with its own budget.
Verification by output
A MEASUREMENT against a peer group, gated by an environmental reading such as irradiance. No photo can stand in for it.
Holdback on durability
Most of the pay on accept, the rest when a no-repeat window holds. In the v0.3 draft; this case pairs it with findings.
Goods kept apart
Panels and parts as goods line items, so labour pay and hardware cost never mix in the proof or the receipt.
Fault rollups
A quarterly proof of every deviation and every verified fix, per string, for owners and the lenders behind them.

Example economics: drone $60, cleaning by the run, technician $280 with 15% held for seven days, the panel billed as goods. Developer docs
