What Does a Solar & Battery System Inspection Include? A Bay Area Homeowner's Guide

If you own a home with solar, you already know the monitoring app can tell you how much power the system produced today. What it can't tell you is whether the inverter is aging, whether your disconnect is properly rated, or whether the wiring behind the panels is holding up the way it should. A solar inspection gets into that.

Here's what you can expect from a Solar & Battery System Inspection with Gelfer Electrical Services, and how to know if it makes sense for your situation.

Signs That Justify an Inspection

Not every system needs a formal inspection right now. But there are clear signals that one is worth doing:

• Lower production than expected, or a noticeable drop compared to the same period last year

• Inverter or battery alerts that have come up in your monitoring app or on the equipment itself

• You're buying a home that already has solar installed and want to know what you're getting

• You're planning to add battery storage to an existing system

• Visible damage, unusual sounds, or anything about the system's operation that seems off

In each of these cases, a professional review gives you a grounded picture of what the system is actually doing — not just what the dashboard says.

Why Monitoring Apps Don't Tell the Whole Story

Modern inverters and battery systems have good monitoring. If your system is communicating, you'll know production numbers and you'll usually get a fault code if something goes seriously wrong. What you won't get is the condition of the electrical equipment itself.

Monitoring tells you about performance. It doesn't tell you whether the DC disconnect has signs of heat damage, whether the inverter's ventilation is clear, whether conduit fittings have worked loose, or whether a recent shade change from tree growth has quietly been costing you production for a year. Those observations require eyes on the equipment.

What Is Reviewed

During a 90-minute site visit, I review the accessible components of the system. That includes:

• The inverter: visible condition, ventilation, indicator lights, and any logged faults

• The DC disconnect and any rapid shutdown equipment

• The AC disconnect and related panel connections

• Wiring and conduit runs that are accessible without destructive work

• Battery equipment, when present: enclosure condition, connections, and displayed status

• Monitoring data and production history, when the customer can share access

• Visible rooftop components, only when it is safe to access the roof and rooftop access is included in the appointment

The inspection is visual and non-invasive. Rooftop access depends on safe site conditions and is not guaranteed unless specifically included in the appointment.

Common Findings

No two systems are identical, but a few categories of findings come up regularly:

• Inverter or communication faults that have been logging without triggering an obvious alert

• Shade changes — tree growth, a new structure nearby — that have shifted the production curve in ways the homeowner hadn't connected to the system

• Aging or weathered accessible components that are functional now but worth monitoring

• Configuration or integration concerns, particularly on systems that have had components swapped or added over time

The goal isn't to find problems — it's to give you an accurate picture so you can make informed decisions about the system.

What Is Not Automatically Included

A Solar & Battery System Inspection is a visual, non-invasive review. It does not include:

• Destructive testing or opening sealed components

• Roof repair or any roofing work

• Engineering certification or stamped reports

• Thermal imaging

• IV-curve testing or advanced electrical characterization

• Repairs or replacement parts

If any of those services are relevant to your situation, I'll note it in the follow-up summary and we can talk through what makes sense.

What You Receive After the Visit

Within a few days of the inspection, you'll receive a brief emailed summary covering:

• The equipment observed during the visit

• Your stated concern or the reason for the inspection

• Key observations from the review

• Immediate safety concerns, if any were identified

• Recommended next steps

• The limitations of the inspection — what wasn't reviewed and why

This gives you a clear written record of where things stand and what to do next, without a lot of filler.

Price, Length, and How to Book

The Solar & Battery System Inspection is $300 and runs approximately 90 minutes on-site. The service area covers San Francisco and the Bay Area.

To schedule a visit or ask a question about your specific system, go to gelferelectrical.com. Provide your address, a brief description of what's going on, and any inverter or battery details you have. I'll follow up to confirm availability and timing.
