Fault Finding and Repairs
Even though solar PV systems are generally very reliable, sometimes things do go wrong. If your system stops generating energy or doesn't seem to be generating as much as it used to, one of our expert engineers can come and assess system, identify the problem and resolve any issue quickly and efficiently to ensure that your Solar PV System is back to full working order as quickly as possible. All of our call outs include up to 1 hour of labour and luckily we can resolve quite a large range problems within this period.
- Faulty parts including inverters
- Damage by pests such as pigeons
- Storm damage
- Reduction in electricity generation
- Loose electrical connections
Likely faults in the main components of solar photovoltaic (PV) systems
1. Solar array
Solar panels are very reliable as they dont have any moving parts. It is however possible that DC cables that join them together or the connectors can be damaged by water ingress or pests.
2. Roof mounting
If it sounds like the panels are moving in the wind then its best to get it checked out as soon as possible. It could be a failed anchor or a loose clamp.
For some roof integrated systems where the solar power panels replace the tiles and become flush with the rest of the roof the flashing will need to replaced periodically.
3. Inverter
The Inverter is most likely thing to develop a fault in a solar system. There are a number things that can go wrong but always check your fuse box to see if the solar switch has tripped. Otherwise call us for more assistance.
4. Generation meter
If the meter is blank then typically a switch has tripped in your fuse box. Otherwise it will probably need to be replaced. If the meter has stopped going up it means that something has failed within the system

Common PV problems in detail
Inverter failure
Very few components of a solar PV system have moving parts so therefore they are incredibly reliable. The most common component to fail within a solar system is the solar inverter. Sometimes it is obvious that the inverter has failed by the error code but often it requires an solar engineer to check the system to see were the fault lies. If you system is not working our engineer will check that there is power going to the inverter and the DC voltage across the panels is within the correct range. If the power and DC voltage are all fine then the fault lies with the inverter.
Hopefully the inverter is under warranty and the manufacturer will send a replacement model otherwise it will need to be replaced. Some inverters can also be repaired but it is based on the availability of spare parts. Luckily replacing inverters is often a simple process and newer inverters have an estimated working life of about 15 years. Unfortunately Rayotec are not able to work with systems with micro-inverters.
Blank generation meter
The most common cause of a blank generation meter is that a fuse/breaker has tripped in your fuse box. It is simple for you to check but also be aware that sometimes the solar has its own mini fuse box.
Storm damage on solar
Although solar panels are pretty tough they are known to get damaged in high winds. It is generally a projectile which smashes a panel. If you are unlucky and this happens to you the first thing that you should do is contact your insurance company.
If the model of solar panels is still available then it is a simple swap. However if it is not then the whole string of panels may need to be changed as you
can't mix panel types on a single string. We have the design capability to
come up with a solution that works and is acceptable to
insurance company.
Pigeon issues with solar
If there are pigeons nesting under your panels then you should get it dealt with as soon as possible before the damage the array. We have found that adding a mesh border around the panels are the most effective deterrent.
If your solar system seem to be working well then it is best to call a pest control company who also specialise in solar as they will be the most cost effect option. Many can be found on Google. If the solar system is not working then call us as we may have to lift the panels to undertake repairs before the pigeon mesh is fitted.
Reviews

My Solar panel system developed an intermittent fault, which other companies had tried to fix, but failed. I contacted Rayotec Ltd. The initially had problems d9iagnosing the fault, but persisted and was able to identify the failing component and replace it. The system is now up and running normally. During this time the people involved where polite and did every thing they could to assist me in resolving my problem. I would have no problem in recommending this compan7y.

I don’t usually leave reviews but having saved £5000 from a upgraded system we didn’t even need I felt inclined to leave one. We had a free maintenance visit from a company who was in our area at the time who then claimed my panels were horrifically out dated and needed upgrading which struck us as strange seeing as they’ve worked perfectly for 7 years providing a surplus of power and a healthy return. A quick phone call to Rayotech immediately confirmed my suspicions as there’s absolutely nothing wrong with our panels at all!!! I’m grateful to have found a honest company to maintain our solar panels moving forward and would happily recommend them to anyone in similar situations.

We have many years of experience of Rayotec who installed our solar water heating panels and solar generating panels and battery. The firm has been outstanding in everything they have done for us. Yesterday we made rang them to enquire about the use of a Smart meter, which our elecricity supplier is pushing. We received comprehensive and very helpful advice from Perry Viner who also, at our request, told us about another firm who do solar panels as, very sadly, Rayotec no longer install them as we were thinking of increasing our number. Rayotec are happily going to do our maintenance for us. A truly professional company who we would recommend absolutely to anyone.

Rayotec installed our Solar PV system so when the inverter failed, typically only months after the manufacturer's warranty expired, I contacted them about a replacement. I spoke with Reza who gave me two options with prices and when I had made my decision Reza kept me informed of progress of the order and the install date. The wait time for installation was only one week and good communication was maintained throughout this period. Dave came to install the new inverter and he was excellent. He was punctual, very efficient with a high level of expertise, very helpful and always polite - a credit to Rayotec. When Dave identified a further problem with my panel array, caused by nesting Jackdaws between the panels and the roof, he was again very knowledgeable and helpful in recommending a pest control company who could resolve the problem. I am very happy with the service I received from the Rayotec Team and cannot recommend them highly enough.

I've had underfloor heating and solar panels fitted by Rayotec, I'm very happy with both the work done and the top service they gave me. They are friendly, professional, I had a small problem with the boiler system, which they very kindly took the time to explain how it all worked so the issue was resolved. They really went above and beyond the call of duty, and I recommend them highly to others, no problems at all. I'll be booking them again for another job on another property very soon.
Customer, Lingfield
We had our solar panels serviced by Rayotec. The Engineers arrived on time and were very efficient, the men were pleasant and polite and explained in details what they were doing, very helpful
