Solar Panel Monitoring

A solar array can lose output for weeks before anyone notices — a shaded string, a failing inverter, a box quietly underperforming. Collie’s dashboard tracks production down to the individual panel, so a dip gets caught the day it starts, not the quarter it shows up in the bill.

A quiet loss is still a loss

Solar underperformance rarely fails loudly. It just produces a little less every day, until someone finally compares the bill to the forecast.

Invisible degradation

Dust, shading, and ageing cells reduce output gradually — nothing dramatic enough to trigger a manual inspection on its own.

Only the total is visible

Without panel-level data, a site only sees the combined number — never which specific panel or box is dragging the average down.

Costly manual checks

Sending someone to physically inspect every panel across a large roof or field is slow, and it only checks whatever day someone shows up.

From the whole site down to one box

The dashboard zooms from a single total-output number all the way down to the specific panel that needs attention.

Energy production dashboard

Live and historical kWh output, peak power, and efficiency, tracked continuously against expected generation.

Panel list view

Every panel or string in the array, listed with its current status — producing normally, underperforming, or offline.

Box panel details

Drill into a single combiner box or panel to see its voltage, current, and yield against its own historical baseline.

Efficiency alerts

When a panel or box drifts below its expected yield, an alert is raised automatically — no need to wait for the monthly review.

How it flows

Generate. Compare. Alert.

01

Generate

Every panel and box reports its output continuously, feeding one live production number for the whole site.

02

Compare

Each unit’s output is measured against its own expected yield — not a generic average that hides individual problems.

03

Alert

A drop beyond the expected range flags that specific panel or box, so maintenance knows exactly where to look.

Generate. Compare. Alert.

A rooftop panel in full sun and one partly shaded by a vent shouldn’t be judged against the same number. Collie compares each panel or box to its own expected output, so an alert always points to a real, specific problem — not just normal variation across the array.

A visual check, without the ladder

For large rooftop or ground-mounted arrays, a Collie robot can carry the same vision module used for site surveillance to visually inspect flagged panels up close — cutting down on manual roof access for routine checks.

Solar panel monitoring system tracking output, faults and array performance

Where it’s deployed

Anywhere panels are on the roof

Industrial Sites

Rooftop and yard installations feeding production floors, tracked against facility energy demand.

Hospital

Backup and supplementary solar capacity monitored for reliability alongside critical loads.

Offices

Corporate rooftop solar tied to sustainability reporting and energy cost tracking.

Warehouses

Large flat-roof arrays where panel-level detail matters most, given the sheer number of units.

Frequently Asked Questions (FAQ)

What does Solar Panel Monitoring track?

It monitors panel-level performance data such as output, efficiency, and fault conditions, so underperforming or damaged panels can be identified without manual inspection.

How quickly are faults or drops in output flagged?

The system compares live output against expected performance and flags anomalies as they occur, rather than only surfacing them at the next scheduled maintenance visit.

Can I monitor multiple sites from one dashboard?

Yes – panel data from multiple installations feeds into the same Collie dashboard, so a facilities team can track several sites without switching systems.

Does it help with maintenance scheduling?

Historical performance trends make it easier to prioritise which panels or strings need attention first, turning maintenance into a data-driven schedule instead of a fixed calendar routine.

Can this integrate with existing solar inverters or monitoring hardware?

Solar Panel Monitoring is built to pull readings from panel-level sensors and standard monitoring hardware into the Collie dashboard – get in touch to confirm compatibility with your specific inverter setup.
