Most calls to a solar electrician in Cyprus have nothing to do with the panels. Modules themselves fail rarely. What fails is the inverter, the DC isolator sitting on the roof, the plugged connectors between strings, and the AC side running back to the consumer unit — and all of that is work for a registered electrical contractor rather than a general handyman. So the first question to put to anyone quoting is not what it costs. It is whether they are registered to certify the work once it is finished.

The ten questions we get most

  1. The system produced nothing today. Is it the panels or the inverter?
  2. Do I have to call the company that installed it, or can any solar electrician take the job?
  3. Does the person doing the work legally have to be registered?
  4. There is a brown mark and a warm smell around the rooftop isolator. How urgent is that?
  5. The inverter throws an insulation or earth-fault error, usually after rain. What causes it?
  6. Is there such a thing as an emergency solar electrician, and will anyone come out at the weekend?
  7. My installer has closed down. Can somebody else take the system over?
  8. I want to add a battery. Does that mean a fresh application to the Electricity Authority?
  9. One string reads lower than the other. Shading, fault, or normal?
  10. Can the same electrician fit an EV charge point while they are on site?

Short answers

Panels or inverter. Panels degrade slowly; inverters stop. If output went from normal to zero between one day and the next, look at the inverter, its AC breaker and the DC isolator before anyone goes near the array. A total loss overnight is almost never a module problem.

Original installer or anyone. Any registered electrical contractor can work on the system. Whether they want to is a different matter — some decline work on inverter brands they cannot get parts for locally, which is a real constraint on an island this size.

Registration. Yes. Work on a grid-connected installation has to be carried out and certified by a registered electrical contractor, and the certificate is what your connection paperwork rests on. ETEK holds the register of qualified professionals and the Electricity Authority of Cyprus deals with the connection side; both are worth a check before you agree to anything.

Burnt mark at the isolator. Treat it as urgent. Discolouration or heat at a DC isolator means a loose or arcing connection carrying direct current, which does not self-extinguish the way an AC arc does. Shut the system down at the inverter and the AC breaker, leave the roof alone, and get an electrician out that day.

Insulation faults after rain. Water finding its way into a connector, a damaged cable sheath rubbing on a roof edge, or a junction box that has taken UV damage. It often clears once the roof dries and comes back on the next shower, which is exactly why people ignore it. It is a fault, not a quirk.

Emergency call-outs. They exist, and they are priced differently from a booked visit. Outside normal hours you are paying for the response as much as the repair. If the system is simply producing nothing and nothing smells hot or looks damaged, a booked visit on a weekday is the cheaper and equally safe choice.

Installer gone. Common enough. The practical problem is rarely the wiring — it is that the previous company holds the inverter's monitoring account and sometimes the only record of how the strings were laid out. Ask for both in writing before you need them.

Adding a battery. Storage changes the installation, so expect the paperwork to change with it. What is being altered is how the property behaves at the meter, and that is the Electricity Authority's concern rather than your electrician's preference. Have the installer confirm what has to be resubmitted before ordering equipment.

Uneven strings. A consistent gap between two strings usually means different orientation, different module counts or a shading pattern. A gap that appears mid-morning and closes by afternoon is shading. A gap that appeared suddenly is a fault.

EV charge point. Usually yes, and doing both in one visit avoids paying twice for the same access. What decides it is the incoming supply and the existing consumer unit, not the solar system.

Where the answer depends

Price for the same fault moves for reasons that have little to do with the fault itself.

Access. A ground-floor inverter in a garage in Latsia and a rooftop isolator on a hillside plot in Peyia are different jobs. Steep access roads there limit vehicle and platform size, and where a platform cannot get in, the labour goes up. Our district pages record where access is the constraint rather than the distance.

Roof type. Most Cypriot houses have flat concrete roofs with the array on tilt frames, which makes safe access straightforward and repair time short. Pitched tile roofs and apartment blocks are slower, and on a block the roof is usually common property, so you may need the management committee before anyone climbs up.

Grid position. In dense tourist-area networks like Germasogeia, solar export applications often need a load assessment on the local connection, which turns a simple addition into a sequenced job. That is a scheduling issue, not an electrician issue, but it lands in the same quote.

Season. Summer is peak fault season because inverters run hottest exactly when they are working hardest, and it is also when everyone else calls. If a system has a known intermittent problem, chasing it in April costs less waiting time than chasing it in August.

Distance. Travel is priced into most day rates outside the main contractor bases. A Paphos-based electrician quoting for Polis Chrysochous is quoting for the drive as well.

What nobody asks but should

  1. Who holds the monitoring account?

    The portal login is usually created by the installer in their own name. When they leave the market, you lose the history that would show an electrician when the fault started. Ask for the account to be transferred to you at handover, and check that it actually was.

  2. Is there a string diagram anywhere?

    A single sheet showing how many modules are on each input, and where the isolators are, takes the tracing work out of every future visit. Most systems in Cyprus do not have one. Ask for it while the people who built it are still reachable.

  3. Is the DC isolator rated for this roof?

    It is the most UV-exposed component in the whole array and the one that fails most often here. Enclosures rated against temperate-climate exposure chalk and crack considerably faster on a Cypriot roof, so its condition belongs on every maintenance visit.

  4. Can the inverter still be supported locally?

    Ask whether the brand has an importer in Cyprus and what a replacement unit's lead time looks like. An orphaned inverter is a working system that stops for weeks instead of days.

  5. Are the fixings right for a coastal site?

    Near the water — Kato Paphos being the obvious case — salt-laden air is standard, and galvanised or marine-grade fixings are what belongs on the roof. Mixed metals on a coastal mounting system are a corrosion problem, and salt air brings the day it shows forward rather than pushing it back.

Common questions

Can I isolate the system myself before an electrician arrives?

You can turn the inverter off and switch off its AC breaker at the consumer unit, and that is worth doing if something is clearly wrong. Do not go to the roof and do not touch the DC side. The array is live whenever there is daylight on it, and there is no switch that changes that.

Does an annual electrical check make sense on a small domestic system?

It makes more sense here than the equipment manuals assume, because the combination of UV, heat and salt ages the exposed components faster than the temperate-climate figures they were written against. Connections, isolator condition and earthing are the parts worth eyes on.

How do I check someone is actually registered?

Ask for the registration and check it against the professional register rather than against a printed logo. The electrical service pages on this site list contractors with their registrations shown, and the price pages give you the current ranges to hold a quote against.
