Diagnostics

A drop in energy production, a tripped inverter, or a warning light on your monitoring app can mean a dozen different things. Our solar diagnostic service pinpoints the real cause — quickly and clearly — so you know exactly what's happening and what (if anything) needs to be done next.

Why choose SwiftSolar D&R for diagnostics

We don't guess, and we don't upsell. Our technicians test your system methodically — panels, wiring, connections, and inverter — to identify the actual source of the issue, not just the symptom. Because detach and reset work is our specialty, we understand solar hardware at a level most general contractors don't. You'll get a clear explanation of what we found, in plain language, with honest next steps.

What's included

• Full system performance check

• Panel-by-panel inspection for damage, wear, or shading issues

• Wiring and connection testing

• Inverter and monitoring system review

• Clear, written report of findings and recommendations

The problem we solve

When a solar system underperforms, it's easy to assume the worst — or to ignore it and hope it resolves itself. Neither is a good plan. Unaddressed issues can compound, cost you money in lost production, and in some cases affect your warranty. A proper diagnostic gets you answers fast, so you can make an informed decision about repair, servicing, or simply confirming everything's fine.

FAQ

What are signs I might need a diagnostic visit?

A noticeable drop in energy production, error codes or warning lights, unusual noises, or a system that isn't matching your monitoring app's expected output are all good reasons to have us take a look.

How long does a diagnostic visit take?

Most diagnostic visits can be completed in a single appointment, though the exact time depends on the size and complexity of your system.

Will you fix the issue during the diagnostic visit?

Diagnostics is focused on identifying the problem and explaining your options. Depending on what we find, repair work may be scheduled as a separate visit.

Can a diagnostic affect my solar warranty?

No — we follow manufacturer-approved inspection procedures, so a diagnostic visit won't put your warranty at risk.

Do you diagnose issues related to roof damage as well as the solar system itself?

We focus on the solar system itself, but we regularly coordinate with roofers and insurance adjusters when a solar issue is tied to roof damage or a claim.
