Pharos Data
Inspection and progress monitoring.
The surveyor you no longer book. A visiting contractor inspects your site once a year, on a day that suited the diary. The station that lives on your ground inspects it monthly, and again after every storm, with no mobilisation to arrange and nobody to fly in.
That is the whole difference. Not a better camera. A shorter gap between the fault appearing and you knowing about it.
What comes back
Three reports the station already flies for.
-
Solar fault reports
Module level thermal inspection, graded and costed, so the repair list writes itself.
- Severity graded fault map over the array.
- Estimated rand loss per fault.
- Prioritised repair list.
- Monthly cadence, plus post storm sweeps.
-
Construction progress reports
What is actually built, counted, against what the programme said would be built.
- Daily or weekly orthomosaic of the site.
- Piles, structures and panels counted.
- Progress against plan.
- Daily reporting where the programme needs it.
-
Mining stockpile volumetrics
Same flight path, same method, every day, so your stock numbers move for real reasons.
- Scheduled photogrammetry passes.
- Volume per stockpile.
- Stock movement tracked over time.
- The method recorded on every pack.
When the job needs survey accuracy, the same station flies a different aircraft built for it.
The Matrice 4D, the mapping aircraft, with a mechanical shutter and RTK. Same ground, same station, a different tool out of it.
The work
Four families of daylight work.
- Thermal inspection Heat as the tell. Panels, joints, bearings and stockpiles read against their neighbours under the same load and the same weather, with the conditions logged at capture.
- Progress tracking The same site, the same waylines, on a schedule. What changed since the last pass is the deliverable, not a single pretty afternoon of it.
- Measurement Topography and volumetrics. Surfaces, stockpiles and earthworks measured on a repeat grid, with the method recorded so your own surveyor can sign it off.
- Verification As built against as drawn. What is on the ground today, positioned and dated, so a claim about the site can be settled by looking rather than arguing.
What lands on your desk
A fault map, and the case for fixing each one.
Every anomaly is pinned to its module and string, graded, and carried through to what it is costing you a year and how long the repair takes to pay for itself. Below is a sample pack from a plant that does not exist.

- No finding
3 critical, 5 high and 10 to watch across six blocks. Every one of them is listed in the register with a photo, a position and a grade.

Illustrative figures on an invented plant. Real numbers come off your own array, your own yield and your own tariff.
Commercial rooftops
Fly in the morning. Faults on your desk before lunch.
A commercial rooftop under 1 MW is one short flight. The array is scanned, the anomalies are graded, and the pack is with you inside the hour. It is the smallest job the station does, and the fastest thing it gives back.
This one is a rooftop story. It holds for arrays under 1 MW and we do not stretch it further than that.
By industry
The station is already there. Put it to work.
The sentry that never sleeps, and the surveyor you no longer book. The same aircraft flies daylight inspection work, delivered as reports on the same monthly bill.
-
SolarThermal panel inspections with a fault map and repair list.
- Thermal and visual on the same pass, so soiling and droppings are told apart from real electrical faults.
- Every anomaly pinned to its module and string: cell hotspots, a hot substring behind a failed diode, a module or a whole string gone dark.
- The same waylines every time, so you see how the plant is ageing instead of one afternoon of it.
You get a fault map over the array, a severity ranked defect register with a photo per fault, and a repair list in priority order.
-
MiningStockpile volumes and haul road checks in a monthly report.
- Stockpile volumes from a repeat grid: volume per pile, and the change since last month.
- Haul roads flown as a corridor. Potholes, ponding, berm loss and drainage failure, pinned and classed.
- Thermal over coal stockpiles and discard dumps for hotspots before they take hold.
You get volumes with the method recorded, an orthomosaic, a haul road defect register, and the surface model your own surveyor signs off.
-
TailingsScheduled facility surveys with a visual record for compliance teams.
- The full footprint on identical waylines every month. The dated archive it builds is the product.
- Freeboard, pool position and beach width, trended flight to flight rather than guessed between visits.
- An early sweep of the downstream face and toe for wet anomalies, reported as differences, never as verdicts.
You get the trends, a surface change map, an anomaly register, and an accuracy statement on every pack. It is the visual layer of your monitoring stack, not a replacement for your instruments.
-
InfrastructurePowerline and substation thermal scans.
- A standard shot list per bay from safe standoff: bushings, breakers, arresters, busbar joints, cooling.
- Hot joints reported against a similar component under similar load, with the load and the weather logged at capture.
- Structures and hardware within reach: cracked insulators, loose clamps, broken strands, nests, theft damage.
You get a condition register with photos and positions, and a thermal findings report with an action band on every finding.
-
Rail and portsPatrols over known theft corridors within station reach.
- The sections a station reaches, flown along the servitude with every image tagged to chainage.
- By night for theft, by day for condition, on one subscription. Missing spans, stripped masts, cut fences, staged vehicles.
- Change against the last pass: new dumping, encroachment, vegetation into the envelope, fence breaks.
You get a patrol report per section with an incident and defect register, a comparison against the previous pass, and urgent findings called through live.
-
Estates and reservesFence, dam and infrastructure audits.
- The boundary traced on a schedule, dwelling at gates, corners and the dead ground where people actually cross.
- Dam extent and level trended from the same waylines. Roofs, pump houses and sheds checked as a comparable set.
- Fire sweeps folded into the patrol along plantation and fynbos edges, with coordinates and stills on anything found.
You get fence and gate defects with positions, a dam trend, a building condition set, and a fire watch log, on one bill with the night watch.
It is the same discipline, pointed at daylight. Flown in idle windows, no mobilisation cost. Open any one of them.
