Solar repairs, inverter replacement and maintenance in Kent

Signs your system needs attention

Warning lights or error codes on the inverter, a monitoring app that shows nothing, or generation well below the same month in previous years are all reasons to get a system looked at. Physical signs include cracked or discoloured panels, loose cables, scorch marks near isolators and pigeons nesting under the array. Keep a note of your generation meter readings, as they make fault-finding easier. Don't open the inverter or go onto the roof yourself: solar panels produce voltage whenever there's daylight, even when the system is switched off at the inverter.

Replacing an inverter

Inverters usually have a shorter working life than panels, so many systems need a replacement inverter at some point. A like-for-like swap is the simplest option, but if you might add a battery later, a hybrid inverter can be worth considering now. The replacement should be compatible with your panels and wiring, and your installer may need to update the details held by UK Power Networks. If you receive Feed-in Tariff or SEG payments, tell your supplier about the change and keep the new paperwork with your original MCS certificate.

Health checks, cleaning and bird proofing

A periodic health check covers the inverter, isolators, cables, connectors and roof fixings, and tests the electrical side of the system. In Kent, rain usually keeps panels reasonably clean, but systems near farmland, the coast or busy roads may gather more dirt or salt. Cleaning at height needs proper access equipment, so it's a job for professionals. Pigeons nesting under panels can damage cables and make a mess, and mesh fitted around the edge of the array is a common fix. Ask what each visit includes and whether you'll receive a written report.

Solar repairs, inverter replacement and maintenance: common questions

My original installer has closed. Can someone else repair my system?

Yes. Many installers work on systems they didn't fit. Have your MCS certificate, inverter model and any warranty paperwork ready, as this helps them diagnose the fault and check what cover may still apply.

Do solar panels need cleaning?

Not often in most of Kent, as rain does much of the work. Panels near farmland, the coast or under trees may need occasional cleaning. Use a professional with proper access equipment rather than climbing on the roof.

Can panels be removed so my roof can be repaired?

Yes. Installers can take panels down, store them and refit them once the roofing work is finished. Ask your roofer and installer to agree the order of work and who reconnects and tests the system.
