Start with the right questions

A clear diagnosis is the first useful result

Low solar output can have several causes, from weather and shading to an equipment fault or a monitoring problem. That is why a repair enquiry should begin with observations, not a preselected replacement part. A qualified provider can review the system history, inspect the installation and recommend further testing where it is justified.

Ask for the diagnosis and proposed remedy in writing before approving additional work. The report should distinguish an urgent safety issue from a performance concern and show what the provider has actually checked. SolarQuery helps you reach the right kind of specialist; repairs, warranties and payments are arranged directly with them. If there is smoke, fire or an immediate electrical hazard, seek urgent local assistance rather than waiting for an enquiry response.

What to include in the brief

A clear scope makes better conversations.

Choose the work you need, then agree the exact responsibilities with your provider.

01 / SCOPE

Inverter fault assessment

Share the displayed fault code, model and when the issue occurs. A technician can distinguish equipment problems from wider electrical or operating conditions, then explain whether repair, manufacturer support or replacement is the appropriate next step.

02 / SCOPE

Low-generation investigation

Compare generation records with the system’s history and local conditions. Ask the provider to consider weather, shading, soiling, outages and equipment condition before concluding that the panels have deteriorated or that a larger system is needed.

03 / SCOPE

Electrical fault diagnosis

Qualified personnel can assess wiring, connections, protective devices and related electrical equipment. Agree a clear inspection scope and safe access arrangements. Homeowners should not open equipment, handle exposed wiring or repeatedly reset a system that is tripping.

04 / SCOPE

Module and string testing

Where initial findings justify it, ask about detailed tests that can help locate underperforming sections. The provider should explain why the test is needed, what evidence it produces and how that evidence informs the proposed remedy.

05 / SCOPE

Thermal inspection

Thermal imaging can support an investigation into abnormal heating. Ask the specialist to interpret findings alongside operating conditions and other checks, rather than treating a coloured image alone as a complete diagnosis or a reason for replacement.

06 / SCOPE

Repair verification and records

After authorised work, request the findings, replaced-component details and commissioning or test records relevant to the repair. Agree how restored operation will be checked and whom to contact if the same symptom appears again.

Discuss my requirements
Different sites. Different priorities.

Find the approach that fits your project.

A single fault or warning

Best suited to a specific error message, repeated trip or failed component. Share when it started and whether anything changed recently, such as building work or a storm, to help the provider prepare for the visit.

An unexplained performance drop

Useful when the system appears to run but generation is consistently below expectations. Supply historical readings and bills if available, and ask for a staged investigation that separates measurement problems from actual generation losses.

A wider plant condition assessment

Consider a broader review after prolonged downtime, a change of maintenance provider or recurring faults across a commercial plant. Agree the equipment coverage, test selection and prioritised findings expected in the final report.

Before you commit

The details worth discussing.

Make safety the first question

Describe visible damage or unusual smells from a safe location without approaching electrical equipment. Stay away from damaged panels, exposed cables and flooded equipment. A competent professional should decide the safe inspection and isolation process; a web enquiry is not emergency support.

Check warranty routes first

Keep installation invoices, serial numbers and previous service records available. Ask whether the installer or manufacturer needs to approve the work before another contractor intervenes. A product warranty, workmanship warranty and paid repair service can have different responsibilities and exclusions.

Separate diagnosis from repair approval

Confirm the visit or diagnostic fee and what it covers before booking. Ask the provider to request your approval for parts, extra testing or repeat visits. A well-defined first visit helps you compare offers without pretending the fault is already known.

Keep a useful record of symptoms

Note dates, error messages, unusual shutdown patterns and relevant changes at the property. Photographs of an accessible display can help, but never climb onto the roof or open a cabinet for evidence. Good observations help the provider investigate efficiently.

Cost and scope

Understand what shapes the quotation.

Repair pricing depends on the diagnosis. A first-visit fee may cover inspection but exclude parts, specialist testing, access equipment or further attendance. Ask for those boundaries clearly, then request an itemised repair proposal. Compare the expected benefit, warranty position and remaining equipment life before agreeing to a replacement.

  • System capacity and the equipment involved
  • Diagnostic depth and specialist instruments required
  • Site access, travel and repeat attendance
  • Replacement parts, manufacturer support and warranty status

Questions before you enquire

A little more clarity.

These answers can help you prepare. Your provider should confirm the details for your property and the work required.

Ask about my project
Why are my solar panels producing less electricity?

Weather, seasonal sunlight, shading and dirt can affect generation, as can equipment faults. A monitoring connection problem may also make the figures look unusual. Compare records over a meaningful period and share them with a provider. One low reading does not establish that the panels are faulty.

My inverter keeps tripping. Should I keep resetting it?

Repeated trips need professional investigation. Repeatedly restarting the system can leave the underlying fault unresolved. Record the message from a safe position and contact an appropriate service provider or the manufacturer’s support team. Do not open the inverter or attempt electrical work to clear the fault yourself.

Can a provider repair a system installed by someone else?

Some providers accept existing installations from other installers, subject to assessment, location and equipment support. Mention this when you enquire and share the original records. Ask whether diagnostic work could affect an existing warranty and whether manufacturer authorisation is needed before repairs can proceed.

Does a thermal scan find every solar problem?

No. Thermal imaging can reveal unusual temperature patterns, but it is one tool within an investigation. The result needs interpretation and may require electrical or performance checks. Ask why it is recommended for your case and what additional evidence the provider will use before proposing corrective work.

Will SolarQuery send a technician immediately?

Our team first checks your requirements and looks for a relevant provider for your area and equipment. Attendance depends on that provider’s availability and agreed scope. This is not an emergency service. If immediate danger is present, keep clear and contact local emergency or electrical assistance.
