       Solar PV system repairs from £90

If you’ve found out that your solar PV system isn’t working properly, or at all, it’s probably come as something of a shock.

Many systems were sold with false promises of 20+ years maintenance-free, and just a few years in you find yourself facing a repair bill. Most problems where the inverter is not at fault are down to poor workmanship by the installers.

You may find that the original installer is no longer trading, and that your workmanship warranty insurance isn’t worth the paper it’s printed on.

We can come to your home and diagnose the fault for £90 .

Terms and conditions: This fee covers up to one hour and is for work within a reasonable travelling distance to your location . We are happy to consider working any where in the UK but a reasonable

charge would be made to cover the additional fuel and time. If your system is repairable within the one

hour, you would be charged for any parts used.

If we need to replace the inverter or another part not held in the van then we will need a second visit. In these cases we will usually be able to offer a fixed price quotation for the repair.

If access to the roof is necessary then a further visit may be necessary to erect a safe means of access.

Inverter faults

Where there is still warranty left on the inverter, we will raise a claim with the inverter manufacturer and obtain and fit a replacement unit. The majority of inverters will have a five year warranty, although there

are exceptions to this.

If the inverter is out of its warranty, we will quote for a good quality replacement with a ten year warranty. There are also upgrade options available for a premium system with a twenty year warranty that will outlast your Feed in Tariff.

Inverter faults require two repair visits, one to diagnose the fault and then one to repair or replace the inverter.

 String faults (i.e. faults with the d.c. cables)

This is the second most common fault, and it tends to manifest itself when a system with incorrectly made d.c. connections has been exposed to a few years of our changeable British weather.

The standard of workmanship in many installations is exceptionally poor, with connectors not fitted correctly and cables not kept supported off the roof surface. You can often see this from the ground by looking underneath the solar panels.

Badly fitted connectors allow water ingress, which leads to corrosion. If the cables and connectors are in contact with the roof surface, it is likely that they will accumulate organic debris such as leaf mulch and (particularly near the coast) bird droppings. As this biodegrades it releases ammonia, which will penetrate the connections and accelerate corrosion. Some arrays also suffer from uninvited guests such as pigeons

or gulls

Corrosion of the connectors introduces an electrical resistance in the connections. This causes the connectors to heat up, which can be a fire hazard. Often the inverter will detect a leakage current and will report an insulation resistance fault (also known as Riso or isolation fault). The inverter will shut down to reduce the likelihood of fires.

In some other installations, we have found that the strings are connected incorrectly, i.e. including panels from more than one roof orientation on the same d.c. string. The effect of this is that the solar panels work against each other resulting in much lower yields than expected.

Most solar PV systems are on the roof, meaning that a scaffold is usually required for remedial work.

Due to the cost of having these faults repaired many customers choose to upgrade their panels with Tigo power optimisers at the same time.

This has many benefits including better system performance and unsurpassed monitoring of every part of the solar PV system. We then also give them a twenty year warranty and offer ongoing remote monitoring of the system, effectively taking the customer’s installation under our wing.


Other faults

If your system is tripping the circuit breaker, it could be that the installer has fitted the wrong type of circuit breaker, which we can replace for you.

Although quite rare, the FIT meter can fail and either stop counting up or (in the case of LCD devices) have a blank screen.

Isolators can suffer thermal damage, usually as a result of loose connections or putting in the wrong type of isolator. We have even found cases where installers have fitted an a.c. isolator where a d.c. isolator should be, which are often burned out. This is a fire risk, as we carry all these components in the van, these faults can usually be resolved in one repair visit.

Is your roof letting the rain in?

Roof leaking in?

Finally, your solar PV system may be working very well, but you’ve discovered a stain on your ceiling because the rain is getting in. A correctly fitted roof mounted solar array will never leak in. If you have this problem then we need to inspect the roof and quote for a permanent repair. This often necessitates reinstalling or replacing the mounting structure of the solar panels and will be costly. We are often asked if we will do a ‘quick fix’ with sealants or flashband. We don`t advise this as a cure, but if your budjet at this time is stretched we will help with the understanding that it is a temporary measure (where possible)


Effective system monitoring is an area that has often been ignored, particularly in earlier systems when fewer monitoring products were available. Simply relying on your meter readings means that discovering a fault with your solar PV system may take several months. With a personal display you can see your yields instantly.

We can retrofit monitoring systems from simple displays to remote meter reading systems (useful for landlords).

If you have a hot water cylinder then why not ask us to install an immersion heater controller to maximise your energy savings?

Tigo technology increases system yields and provides unrivalled system monitoring, including every panel’s individual performance. With unsurpassed reliability and a 20 year warranty, it is an excellent upgrade
