Solar Panel Inspection in Barnegat, NJ: What a Pro Catches
Solar panels are built to last 25+ years — but the roof underneath them, and the workmanship holding them up, deserve a check-up long before then. We recently performed a solar panel inspection in Barnegat, New Jersey, on a system that was running fine day-to-day. From the ground, everything looked normal. Up close, it was a different story. Here's exactly what a professional solar inspection here in Ocean County catches.
Why get a solar panel inspection?
Most homeowners never look at their array after installation day. But mounting hardware, flashing, wiring, and monitoring equipment all age — and a small issue caught early is far cheaper than a roof leak or a system that's quietly stopped producing. A professional inspection tells you whether your solar installation is actually protecting your roof and your investment. On this Barnegat system, it surfaced five issues the owner had no way of knowing about.
The system we inspected
- Location: Barnegat, NJ (Ocean County)
- Modules: 35 panels
- Installed: 2017
- Microinverters: Enphase
- Racking: Rockit
- Main panel: Square D
Finding #1: The roof mounts weren't staggered
This was our biggest structural concern. When solar roof mounts are lined up in a straight column instead of being staggered, the weight of the array concentrates on the same rafters top-to-bottom, rather than spreading the load across the roof structure. Over time, that uneven load can become a real problem.
For reference, this is the kind of staggered, evenly spaced mounting layout that shares the load across multiple rafters the way it should:
Finding #2: The system had stopped reporting
One or more Enphase microinverters wasn't producing, and the system wasn't reporting in at all. The culprit was an outdated 3G cell card that can no longer keep the equipment online. Until it's updated or connected to Wi-Fi, there's no way to monitor how the solar system is actually performing — so a dead panel can go unnoticed for months.
Finding #3: Flashing, extra mounts, and debris
A few smaller issues rounded out the report. More than 20 mounts were overhanging the shingle line, where flashing needs to sit properly to keep water moving down the roof. We also found extra mounts drilled outside the array that serve no purpose — every unnecessary roof penetration is one more potential leak point — plus some minor debris on the panels. None are emergencies on their own, but each is worth addressing.
Our verdict
Rated 7 / 10. Overall, we'd rate this solar installation a 7 out of 10. The first fix is getting it connected to the internet right away so the equipment can be monitored. Our other big concern is the mounts not being staggered — we'd recommend having that examined by a pro before it becomes a structural issue down the road.
How often should you have your solar panels inspected?
For most rooftop systems in New Jersey, a professional solar inspection every 3–5 years is a smart baseline — and sooner if you notice a drop in production, a roof leak, or you've just bought a home with existing panels. Coastal Ocean County weather is hard on roofs and hardware, so staying ahead of small issues pays off.
