Solar Panel Repair near you

A good technician starts with the data before climbing anything. Monitoring history usually shows whether the whole system, one string or one panel is affected and when the drop began, and most inverters keep a log of fault codes that narrows down the cause. Mention any recent storm, power outage, roof work or router change when you call.

Solar repairs are electrical work on grid-connected equipment, and the usual rules apply. In Ontario, ESA states that anyone you hire to do electrical work in your home must, by law, be a Licensed Electrical Contractor, and that almost all electrical work, including repairing or replacing existing equipment, must be reported with a notification of work. Once the work passes, ESA issues a Certificate of Acceptance, a document worth keeping for insurance and resale.

In Quebec, electrical work done for others is reserved for contractors licensed through the CMEQ, and Hydro-Québec warns never to connect self-generation equipment yourself, because a non-compliant installation can cause a fire, serious injury or death. Before a technician replaces an inverter or adds panels or batteries, ask whether the utility needs to review the change, since the connection was approved for the original equipment.

An inverter that fails after its warranty can sometimes be repaired, but replacement is often the practical choice, and the new unit has to suit the array's electrical characteristics and the utility's connection requirements. A cracked module is usually replaced with the closest compatible match, since exact models go out of production; a poorly matched panel can hold back the whole string, so the technician checks the specifications before ordering.

Roof repairs and reroofing are where many solar problems begin. The racking is fastened through the roofing into the structure, so a roofer can't simply work around it: a qualified solar or electrical contractor disconnects and removes the array, stores it safely, then reinstalls it with new flashing at every attachment, reconnects it and tests it. Coordinate both trades before the tear-off, agree in writing who answers for leaks at the mounts, and check how removal affects your warranties.

A solar system usually comes with several separate warranties: the panel maker's product warranty against defects, a performance warranty promising that output won't decline faster than a stated rate, the inverter maker's warranty and the installer's workmanship warranty on wiring, mounts and roof penetrations. Their lengths and conditions differ, so find the documents before you pay for a repair.

Snow covering the panels is the most visible winter issue and usually the least worrying: production pauses until it slides or melts off, at a time of year when output is modest anyway. What deserves a call is the damage winter can leave behind, and a sunny stretch after a thaw is a good moment to check that production has come back.
