Solar Fault Finding in Essex

Trusted Solar Fault Finding
specialists in Essex

With thousands of solar PV systems installed across Essex over the past decade, fault finding and repair is an increasingly important service. Systems underperform for a wide variety of reasons — inverter faults, panel degradation, DC wiring issues, battery problems or simply monitoring failures — and many homeowners don't realise there's a problem until they check their generation figures.

We carry out solar PV fault finding across Essex including Chelmsford, Colchester, Braintree, Witham, Brentwood and Basildon. We work on systems we didn't install, across all inverter brands including SolarEdge, SMA, Fronius, Fox ESS, Solis, Solax, Sofar and Enphase. Most faults are diagnosed and resolved in a single visit.

We also work on systems where the original installer has gone bust — increasingly common as smaller solar companies have closed. We're completely independent and give you an honest assessment of the fault, your options and the realistic cost of repair before any work begins.

We regularly work on Essex systems where the original installer is no longer trading. We'll assess your system independently and advise on whether any component warranties remain valid directly with the manufacturer — some do, even years after the installer has ceased trading.

Common Questions

Solar Fault Finding in Essex — FAQs

How do I know if my Essex solar system is underperforming?+
Compare your generation figures against the same period last year, or against the predicted output in your installation documents. A drop of more than 10–15% warrants investigation.
Can you fix solar panels installed by another company in Essex?+
Yes — we work on any solar installation regardless of who installed it. We carry specialist test equipment for all major inverter brands.
How much does solar fault finding cost in Essex?+
We charge a fixed diagnostic fee covering the site visit, testing and written report. Repair costs are quoted separately after diagnosis — you're not committed to anything beyond the initial visit.
My solar inverter is showing a fault code in Essex — what should I do?+
Note the exact code and fill in our diagnostic form. We can often provide initial guidance before visiting. Don't repeatedly reset the inverter as this can obscure the fault history.

Question 1 of 10
What is the main symptom?
Select the option that best describes what you're experiencing.
Question 2 of 10
What inverter brand do you have?
Check the label on the unit — typically mounted on an interior wall near your consumer unit or in a utility room. Older systems may have the inverter in the loft.
Question 3 of 10
Do you have batteries installed?
Battery faults can mimic inverter or panel issues — knowing upfront helps us bring the right equipment and expertise.
Question 4 of 10
How old is the installation?
Age helps us understand likely fault patterns and whether any components may still be under warranty.
Question 5 of 10
How many solar panels are installed approximately?
Helps us understand the system size and likely string configuration.
Question 6 of 10
Is there a fault code showing on the inverter?
Even a partial code is useful — we can often narrow down the likely cause before we arrive.
Question 7 of 10
Do you have monitoring or an app for your system?
Monitoring data can tell us a great deal about when and how the fault developed.
Question 8 of 10
When did you last notice the system working normally?
This helps us understand whether the fault is recent or has been developing over time.
Question 9 of 10
Who installed your solar system?
This helps us understand whether a warranty claim route may still be available to you.
