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 both annual test and inspections and one off health checks.
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 of previous years to assess if there’s 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.
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.
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 uneconomical or damaged beyond repair, we will contact the manufacturer to find out whether it is still within its manufacturer warranty period, if your inverter is outside of the warranty time frame then we will provide you with a quotation for a replacement unit.
In our experience manufacturers generally only carry spare parts for larger or high value inverters for example, Fronius and SolarEdge.
If you would like to discuss either your requirements in more detail or would like a quote, please contact us.
