Privacy policy
If you are dealing with solar savings promises, finance issues, poor installation, underperformance, faulty systems or warranty disputes, your documents and complaint history may need a clearer review pack.
Quick eligibility check
Solar performance
Review output, savings promises and underperforming systems.
Finance concerns
Organise finance agreements, repayments and sales explanations.
Installation issues
Keep installer reports, faults, warranties and repair evidence.
Complaint replies
Track installer, lender and warranty-provider responses.
Common problem
Disputes often stall because key documents, dates, payments and responses are spread across emails, apps, statements, screenshots and complaint portals.
Quaerens helps organise the evidence and prepare a clearer summary so the issue can be reviewed more effectively.
You may want a review if:
Escalation route
A strong solar file does not only look at the installer. Depending on how the system was sold and paid for, the review may also consider finance providers, card providers, warranty providers, manufacturers and complaint routes.
Compare the sales quote, expected output, finance terms, warranties, MCS documents, DNO approval and actual performance.
The route may involve the installer, finance lender, card provider, warranty provider or manufacturer depending on the paperwork.
Where regulated finance is involved, the lender usually has up to 8 weeks to respond before Financial Ombudsman Service escalation may be considered.
If the first response is weak or incomplete, the evidence can be organised for a clearer next step or specialist review.
Specific issues worth flagging early:
Organise documents, screenshots, contracts, receipts and correspondence relating to solar savings promises, finance issues, poor installation, underperformance, faulty systems or warranty disputes.
Turn scattered dates, payments, replies and complaint history into a clearer timeline.
Prepare a more structured case summary and wording for the relevant complaint or review route.
Simple process
Share the issue, value affected, timeline, documents and responses received so far.
We help structure the documents, payments, correspondence and key dates into a clearer review pack.
You receive a clearer view of the evidence, possible gaps and practical escalation options.

Estimated Review Suitability
Potentially suitable
This is only a broad guide. Actual suitability depends on documents, evidence, deadlines, responses received, value affected and whether the issue is appropriate for paperwork-based review.
Start ReviewCompensation reasons
Solar disputes can arise from the way the system was sold, the way it was installed, or the finance used to pay for it. A proper review should look at all three areas because the strongest recovery route may not always be the installer alone.
You may be entitled to compensation where the installation was poor, incomplete, unsafe, or did not perform as promised.
Many solar disputes turn on what was said before signing and whether the savings, benefits, grants or warranty position were explained accurately.
Where solar panels were bought using finance or a credit card, the lender or finance provider may also need to be reviewed.
What Quaerens looks for
We look at the contract, sales paperwork, finance documents, MCS or warranty information, generation figures, repair history, complaint replies and any evidence showing what was promised compared with what actually happened.
Useful evidence
If the response does not match the evidence, a clearer timeline and document pack may help move the issue forward.

If promised savings, finance terms, installation quality or warranty support did not match what you were told, your solar paperwork may deserve a structured review.

Read this guide →Recovery routes
Solar panel claims are not always limited to the installer who fitted the system. If the installer has stopped trading, refused support, or failed to resolve the issue, there may still be other routes worth reviewing.
The realistic route depends on how the system was sold, how it was paid for, what was promised, what finance or warranty documents exist, and what financial loss has been caused by the system.
Where the company is still trading, the claim may involve the installer, sales company, or business responsible for the promises made about performance, savings, suitability or installation quality.
If the solar system was sold with finance, the finance provider may be an important route to review, especially where savings, affordability or the true cost were not properly explained.
Panels, inverters, batteries and workmanship may be covered by warranties, guarantees, certification schemes or insurance-backed protection that should be checked carefully.
In many solar disputes, the strongest losses can include poor generation, failed savings, unsuitable finance, repair costs, inverter or battery failure, electrical faults, unexpected bills, warranty refusal and the cost of putting the system right.
Quaerens can provide a free, no-obligation assessment report setting out what level of compensation appears realistic and which routes may be taken to seek recovery based on the evidence available.

Evidence and escalation route
Solar panel disputes often involve several possible routes at the same time: the installer, the sales company, the finance provider, the warranty provider, the manufacturer, or a card provider. The strongest route depends on what was promised, how the system was paid for, what went wrong, and what evidence shows the financial loss.
A review should compare savings projections, generation estimates, warranty promises, finance explanations and installer statements against bills, monitoring data and real performance.
Where credit, point-of-sale finance or card payments were used, lender complaint routes, Section 75 arguments or Financial Ombudsman escalation may be relevant depending on the facts.
The file should separate repair costs, underperformance, failed equipment, unsuitable finance, lost savings and warranty failures so the complaint is not vague or easy to dismiss.
A formal complaint is normally sent first to the business or finance provider. Where a regulated finance complaint is rejected or not answered within the required complaint period, escalation to the Financial Ombudsman Service may be considered. Quaerens can help organise the evidence and wording so each route is approached in a structured way.
Example solar situations
A homeowner was shown high savings and export-income projections, but bills and monitoring data later showed the system was producing far less than expected.
The installer stopped responding after faults appeared, leaving the homeowner with inverter errors, battery problems or roof-related issues and no clear warranty route.
The monthly repayments, total cost, suitability or cancellation rights were not clearly explained before signing, so the payment route and lender complaint position needed review.
