Why service your solar?

Protect your investment for years to come

Solar panels need very little attention, but like any electrical system they benefit from regular checks. Loose connections, inverter faults, damaged cables or debris on the panels can quietly reduce your output, and some issues can become a safety risk.

Our NICEIC approved and MCS accredited engineers service and repair solar PV, inverters, batteries and EV chargers across Devon, whoever installed your system.

What’s included

What a solar service covers

A thorough check of your whole system, with a clear report and honest recommendations.

Panel and mounting inspection

A visual check of panels, frames, fixings and roof penetrations for damage or wear.

Electrical testing

Testing of DC strings, AC circuits, isolators and connections to confirm the system is safe.

Inverter health check

Checking error logs, ventilation and connections, and updating settings where needed.

Battery check

Reviewing battery health, charge behaviour and settings if you have storage.

Performance review

Comparing your generation against what your system should be producing.

Report and recommendations

A clear summary of what we found and any work we recommend, with no pressure.

Something not right?

Signs your system needs attention

If you notice any of these, it’s worth getting your system checked by a qualified engineer.

Inverter showing an error

A red light, fault code or blank display usually means the inverter has stopped generating.

Lower generation than usual

A drop compared with the same month last year can point to a fault or shading.

Monitoring app offline

Your system may still be running, but you can’t see if something has gone wrong.

Battery not charging

A battery that isn’t charging or discharging properly may need its settings or hardware checked.

Isolator or breaker tripping

Repeated trips can point to an insulation fault, water ingress or a failing component.

Visible damage

Cracked panels, loose cables or slipped fixings should be checked as soon as possible.

In an emergency

What to do if your system fails

If your system has failed or been damaged, only take action if it is safe to do so. Daylight keeps solar panels producing power, so the DC cables from the panels can stay live even when everything else is switched off.

Never touch damaged panels, cables or connectors
If it is safe, switch off the AC isolator, then the DC isolator at the inverter
Keep people away from any damaged equipment
Call us for an emergency callout, or 999 if there is fire or immediate danger

FAQs

Solar servicing FAQs

How often should my solar system be serviced?

We recommend a service every one to two years for home systems, and at least once a year for commercial systems. Regular checks keep your system safe, catch issues early and help keep warranties valid.

Will my solar panels work in a power cut?

Not as standard. Grid-connected systems switch off automatically during a power cut to protect engineers working on the network. If you have a battery with an emergency power supply (EPS), it can keep selected circuits running.

How do I isolate my solar panels?

If it is safe to do so, switch off the AC isolator (usually near your consumer unit or inverter), then the DC isolator at the inverter. Remember that panels still produce power in daylight, so never touch damaged panels or cables. If you’re unsure, call us.

Do you service systems you didn’t install?

Yes. We service and repair solar PV, inverters, batteries and EV chargers whoever installed them.

My inverter is showing an error. What should I do?

Make a note of the error code or light pattern and check whether your monitoring app shows a fault. Some errors clear after a restart, but repeated or persistent faults need an engineer. Get in touch and we’ll help you work out next steps.

What maintenance do solar panels need?

Very little. A periodic visual check, keeping an eye on generation in your app and a regular service are usually all that’s needed.
