Existing systems
Solar Maintenance and Repair Prospecting
We map the arrays already installed across your service radius — commercial rooftops and residential streets — estimate size and vintage, and note visible condition and storm exposure since install. The first 3 are free.
Free preview: 3 properties, delivered 3 business days after we confirm your territory. No card, no call.
The installer who built the array is often gone, and nobody keeps a map of what was left behind.
The original EPC may have been acquired or exited, inverter warranties often expire around year ten, and no single register covers every installed array — least of all the residential systems between your commercial sites. So we build one.

What an existing array tells you from the air, and what it refuses to
Remote evidence is unusually good at finding arrays and bracketing their age, on a warehouse roof or a residential street, and unusually bad at diagnosing them. Both halves are in the table.
| Indicator | Where it comes from | What it settles — and what it does not |
|---|---|---|
| Array footprint and module count | Where it comes fromAerial imagery panel signatures, row spacing, and module geometry | What it settles — and what it does notGives a module count and, with an assumed wattage for the install era, a DC size band good enough to sort a 90 kW roof from a 900 kW one. The interconnection agreement has the real nameplate. |
| Residential arrays and street density | Where it comes fromImagery panel signatures on pitched roofs, residential PV permits, assessor year-built and owner-occupancy fields | What it settles — and what it does notResidential systems are detected the same way but sit on pitched, dormered, and shaded planes, so misses run higher and confidence is marked per property. Their value is density: a street installed in one era routes as a single visit. |
| Mounting system | Where it comes fromImagery shadow geometry, visible ballast blocks, rail and tilt patterns | What it settles — and what it does notSeparates ballasted, mechanically attached, flush metal-roof, carport, and ground-mount systems, which decides crew, equipment, and access cost on a service call. Attachment detail and flashing condition are not visible. |
| Install vintage | Where it comes fromPV-scoped permits, state incentive and interconnection registries, first imagery showing the array | What it settles — and what it does notBrackets the install year, which brackets the inverter population and the warranty position. Where no permit was indexed, imagery gives an upper bound only. |
| Inverter topology | Where it comes fromImagery of pad- or wall-mounted equipment, combiner placement, permit descriptions | What it settles — and what it does notDistinguishes a visible central or string installation from one with no equipment signature, which usually implies microinverters or optimizers. Manufacturer, model, and firmware are not readable. |
| Visible array condition | Where it comes fromRecent aerial imagery | What it settles — and what it does notFlags soiling, vegetation grown in since install, missing or displaced modules, debris, and ponding at the array edge. It cannot see hot spots, diode failures, delamination, string outages, or ground faults. |
| Storm exposure since install | Where it comes fromNOAA severe weather reports and gridded hail swaths, filtered to dates after install | What it settles — and what it does notShows whether the array has taken a 1-inch or 1.75-inch hail day, or a high-wind event, since it was built. It does not prove damage, an open claim, or a covered loss. |
| Who currently services it | Where it comes fromNot observable | What it settles — and what it does notThere is no public source for O&M contract status, incumbent provider, or renewal date. We say so on every property rather than inferring it. |
Arrays installed since the last flight do not appear, and steep-slope, shaded, or parapet-hidden systems can be missed. Your report states the imagery date per property and marks ambiguous detections.
Finding an array is remote work. Diagnosing one is not.
This is a prospecting instrument, deliberately not a condition assessment.
Settled by the report
- Where the arrays in your service radius are, commercial and residential, at parcel and address level
- Roughly how large each one is
- Roughly when each was installed, from permits, registries, or imagery sequence
- What the mounting type implies for crew, equipment, and roof access
- Which severe-weather events the parcel recorded since the array went up
Not settled — inspection or data required
- Whether the system is underproducing, and by how much
- Module-level faults: hot spots, cracked cells, diode failures, delamination
- Inverter make, model, firmware, fault history, or remaining warranty
- Whether hail or wind actually damaged anything, or whether a claim exists
- Who holds the current O&M contract and when it renews
The five checks that turn a detection into an opportunity
- Ask for monitoring access or twelve months of production data and compare it against expected yield.
- Request the EPC contract, interconnection agreement, and equipment list to confirm nameplate and warranty position.
- Establish whether an O&M agreement is in force, who holds it, and when it renews.
- Schedule an aerial or on-roof infrared scan before quoting module-level repair work.
- Confirm roof warranty implications and site access with the owner before any crew goes up.
A service territory you can plan, built from arrays that actually exist.
O&M sells on proximity and timing, so the register places every array at its address and ranks them by size, vintage, and condition. Your team plans the routes from there.
- 01Define the radius and the floorYou give us the drive time or counties, whether you service commercial, residential, or both, and the smallest array worth a truck roll.
- 02Sweep imagery, cross-check recordsWe identify array signatures, then corroborate each against PV permits and interconnection registries where published.
- 03Rank by service opportunityAn analyst orders the territory by size, vintage, and condition, and states confidence on ambiguous detections.
- Existing-array register
- Every array identified, commercial or residential, with address, parcel identifier, and the imagery date it was confirmed on.
- Size band and module count
- Estimated module count and a DC capacity band, with the wattage assumption behind it stated openly.
- Mounting and equipment notes
- Ballasted, attached, carport, or ground-mount, plus visible inverter equipment and what it means for access.
- Install vintage evidence
- The permit, registry entry, or imagery sequence that brackets the install year, with date and jurisdiction cited.
- Condition and storm log
- Visible condition observations plus severe-weather events recorded at that parcel since the estimated install date.
- Owner and site context
- Owner of record, apparent occupancy, site access notes, and the qualification questions still outstanding.
What imagery can prove about an existing array, and what it cannot.
Yes, and residential is where routing density pays: permits cluster by subdivision, so one filing often marks a whole street. Detection on pitched, shaded roofs is harder, so ambiguous properties are marked.
No. Imagery shows soiling, encroaching vegetation, displaced modules, and debris; underproduction, hot spots, failed diodes, ground faults, and inverter faults need monitoring data, an infrared scan, or a technician.
Not necessarily. Detection depends on imagery date, resolution, sun angle, and obstruction, so the report states the imagery date per property and marks the detections our analyst judged ambiguous.
Where a jurisdiction indexes PV permits or the state publishes a registry, the year is cited and well supported. Otherwise we fall back to the first image showing the array, which is an upper bound only.
No. The report establishes that an array exists, roughly how big and old it is, and what the property has been through — not service demand, contract availability, budget, or consent to contact.
