Why this matters
Solar panels can be a good investment when the system is specified honestly, priced fairly and installed properly. The issue is not solar technology itself. The issue is whether the sale, installation or aftercare matched what you were told.
Payback claims can be misleading when they are presented as certain or when system cost, roof conditions and household usage are not included.
We are not a government scheme, energy supplier or solar installer. Solar Panel Advice Centre helps homeowners organise the facts, understand the likely route and decide whether a free case review is sensible.
Warning signs
you were given a fixed payback period without explanation
the calculation ignored real system cost or likely output
export income was treated as predictable profit
battery or roof assumptions were unclear
the sales pitch focused on long-term gain but glossed over practical limitations
your actual savings make the promised payback impossible
What to keep
- payback illustration or proposal
- contract and system cost
- quote, proposal and system specification
- energy bills, export statements and generation data
- battery and tariff information
- messages or notes about sales promises
Where the issue may fit
The right route depends on how the payback period was presented, which assumptions were used, how the system has performed and what your documents show.
- compare promised payback with actual bills, export and monitoring data
- review whether the sales assumptions were fair
- mis-selling complaint if the sale depended on unrealistic payback
- technical review if output is below expected levels
How a free review helps
A free review is designed to sort the issue into the right category before you spend time on the wrong complaint. You can explain what happened in plain English, then add documents later if they are available.
The review normally looks at the sales promise, the written paperwork, the system specification, the installation position and any aftercare or warranty response.
FAQs
Is a payback period guaranteed?
No. It is normally an estimate based on assumptions.
Why can payback claims be unreliable?
Small changes in usage, export rates, roof angle, shading or system output can change the result.
What if the salesperson promised a specific year?
Write down what was said and compare it with the written proposal and actual performance.
