Solar Panel Inspection Cost: $150 to $350 + What It Covers

How much does a solar panel inspection cost

A basic inspection is $150 to $300 (Fixr) or $150 to $350 (Angi, July 2026). Service companies price a takeover inspection higher and credit it against repairs: EnergyAid starts at $299 for former Titan customers, Forme Solar charges $350 to $500 in Southern California. SolarEdge sells a $99 remote System Health Check that reports component status and warranty coverage without a visit. A pre-closing inspection when buying a house with solar is $150 to $500 (EnergySage, June 2026).

What a solar inspection includes

• Per-panel or per-string production readings compared with the system's rated output and the monitoring history.
• Inverter status, error log, firmware and the condition of the DC and AC disconnects.
• Roof penetrations: flashing, sealant and any sign of water entry, inside the attic where accessible.
• Racking torque and grounding continuity.
• Wiring and connectors for UV damage, rodent damage and overheating, including the junction boxes behind panels.
• Monitoring gateway connection and account ownership.
• A written report with photos, which is the document a buyer, insurer or lender asks for.

Solar inspection when buying a house with solar panels

Order it before the inspection contingency ends, alongside the home inspection. The report answers the four questions that matter: does the system produce what the listing claims, is the roof under it sound, is the equipment under warranty and registered, and is the system owned or leased. A general home inspector does not climb onto arrays or read inverters; a solar contractor does. The buying guide covers the paperwork side.

Solar inspection after the installer goes out of business

The inspection is how an orphaned system gets a new baseline. It documents the state of the system on a known date, transfers the monitoring account, registers the equipment with the manufacturers if the installer never did, and produces the list of what needs fixing and what is covered. For Freedom Forever, Titan and other closures, it is also the evidence behind a proof of claim or a request to a lender. If your installer is gone, check the bankruptcy tracker for who holds your account, then come back here for the repair.

Drone and thermal inspections

Thermal imaging finds hot spots (failing cells, bad connections) that a visual check misses, and drones make it practical on steep or tile roofs. Angi puts a drone-assisted thermal inspection at $100 to $300 (March 2026), though that figure is for homes generally rather than solar specifically. For a residential array a conventional per-panel reading from the monitoring data is usually enough; thermal is worth it when production has dropped and the app shows nothing obvious.

An inspection that finds nests under the array leads to a critter guard; one that finds an electrical fault leads to a licensed electrician, and the technician or electrician guide explains which trade does what.
