If your solar PV system has stopped generating and you would like to book a diagnostic call out, the cost for this will be £150+vat for a residential system and £250+vat for a commercial system. If you have more than one inverter and array please contact us for a quote.
One of our experienced engineers will diagnose the fault and let you know what is required to get the problem rectified.
Our prices are transparent, no hidden extras and includes up to one hour labour, which, in our years of experience is always enough time to diagnose the fault.
Many people don’t realise that their solar isn’t producing until they speak to their electricity company to provide their generation meter readings for the last quarter and realise that the screen is blank, has a solid red light or hasn’t been recoding kWh’s.
If you find yourself in this situation, there may be a problem with your Solar PV.
Your generation meter may have gone faulty, your inverter may have an internal error, or you may have an internal or external cable fault.
Below are the most common Solar PV faults we come across –
If you are based in Buckinghamshire, Bedfordshire, Northamptonshire, Oxfordshire, Hertfordshire or Cambridgeshire and are experiencing problems with your solar, we can help.
We carry out annual test and inspections and one off health checks for both residential and commercial customers.
As PV systems age, faults can occur which can lead to unwanted down time, reduced power production and increased risk of fire.
It is important to monitor the condition of your system.
We carry out a full test and inspection and where possible compare results with results from previous years to assess if there’s been any deterioration of the cables, switchgear or components. In addition to this we check that the solar array is outputting the correct amount of power given the available irradiance from the sun on the day of the test.
Solar PV is a big investment so it is important to make sure it is functioning correctly and in safe working condition.
Regular inspection and maintenance can prolong the life of the system and ensure optimal performance.
We charge £180+vat for residential solar PV systems up to 4kW and £295+vat for commercial systems up to 10kW. If you have more than one inverter please contact us for a quote.
Below are some images of extreme faults we’ve found when carrying out repair and maintenance on PV systems that have not been maintained, these images highlight why regular maintenance and inspection is important, especially on older systems.
Damaged DC isolator caused by a loose connection.
Burnt out solar panel caused by bird droppings which caused a hotspot over a period of years.
This inverter had completely burnt on the inside, the inverter casing contained the burning and externally the inverter looked normal.
The customer only knew something was not right because of lack of solar generation.
A customer contacted us because his solar wasn’t producing and an error code was showing on his inverter, upon further investigation we discovered that a squirrel had chewed through the cabling and made itself a home.
We carry out a full diagnostic check of your solar PV inverter and will repair where possible.
If your inverter is deemed damaged beyond repair, we will contact the manufacturer to find out whether it is still within the manufacturer warranty period, if it is we will liaise with them on your behalf to get a replacement unit sent out to you. The Manufacturer warranty only covers the unit itself and not the diagnostic call out or installation of the replacement inverter.
If your inverter is outside of the warranty time frame and we can not source spare parts then we will provide you with a quotation for a replacement unit compatible with your specific solar PV array.
In our experience manufacturers generally only carry spare parts for larger or high value inverters for example, Fronius and SolarEdge.
The image below is of a Fronius IG Plus inverter with a faulty power stack, to the right is the replacement part sent by the manufacturer. As soon as this was replaced, the customer was back up and generating again, the part was dispatched the same day we diagnosed the fault.
If you would like to discuss either your requirements in more detail or would like a quote, please contact us.
