Silent string outages
One combiner fuse or a failed optimizer takes a whole string offline. The array keeps reporting, just lower.
- Typical loss4–9%
- Found byMonitoring alarm
Commercial O&M
A system nobody watches is a system losing money.
Arrays do not fail loudly. A tripped string, a dirty module row or a dead monitoring gateway quietly removes 8–15% of production and keeps billing you nothing. We monitor, inspect and repair commercial portfolios, including arrays we did not build.

What goes wrong
The four failures that cost the most.
None of these trip a breaker or call anyone. They show up as a production number that is a little lower than last year, which is exactly why portfolios go years without noticing.
Soiling and snow
Dust, pollen and winter grime build up on low-tilt commercial arrays, which never get a good rain rinse.
- Typical loss3–7%
- Fixed byScheduled wash
Dead monitoring
A site changes its network or the gateway dies. Production is fine but nobody can see it, or prove it for an incentive filing.
- Typical lossReporting only
- Fixed byComms repair
Roof and penetration wear
Ballast shift, chafed conduit and failed pitch pans turn into a roof claim long before they turn into a power problem.
- Typical lossRoof damage
- Found byAnnual inspection
Inverter faults
The single most expensive component and the one with the shortest life. Lead times run weeks if nobody is tracking warranty status.
- Typical lossFull site
- Fixed byWarranty + spares
Wildlife and vegetation
Birds nesting under modules, rodents in the DC runs, trees that were small when the array went in.
- Typical loss1–5%
- Fixed byAbatement visit

Orphaned systems
Your installer is gone. The array is still on the roof.
Solar has had a decade of companies closing, selling and walking away from service obligations. We take those systems over regularly. The first step is not a contract. It is a condition assessment that tells you what you actually own, what is still under manufacturer warranty, and what it will take to get production back to where the original model said it should be.

How a ticket runs
From alarm to closed, with a person's name on it.
01
Alarm hits our desk
Monitoring flags the fault before the site does. Most owners hear about the problem from us, not the other way round.
Automatic
02
Remote triage
A technician checks inverter logs, string data and comms. A real share of faults clear remotely without anyone driving anywhere.
Same day
03
Dispatch
If it needs hands, you get a scheduled window and the name of the tech coming. Site contacts and access requirements are already in the file.
24–72 hr by plan
04
Repair and verify
Fix, then confirm the string is back at expected output before the truck leaves. Photos and readings attached to the ticket.
On site
05
Close out
Written summary, warranty claim filed if the part qualifies, and the recovered production quantified in the monthly report.
