Specialist work
After-sales — the engineer who built it answers the phone
The person who designed and commissioned your system is the person who answers when something looks wrong. That is the whole commitment, and here is exactly what it covers.
One
Person you call
The engineer who designed and commissioned the system
12 / 25–30
Years product / performance warranty
Typical tier-one module terms — from the manufacturer, not from me
5–10
Years inverter warranty, typically
Extension usually available at purchase, not afterwards
Whether this fits
Work out whether you should be talking to me at all
This is for you if
You want the designer accountable rather than a call centre
Diagnosis is faster when the person on the phone already knows your string layout and does not have to be told what was installed.
You will not chase a manufacturer warranty claim yourself
Most people will not, which is how warranties quietly expire unclaimed. Claims are raised on your behalf.
You want the warranty register kept for you
Expiry dates matter far more than warranty length. A claim raised in year eleven and one raised in year thirteen are very different outcomes.
This is not for you if
Anyone needing a 24-hour emergency response commitment. I am one engineer, not a service company with a standby rota, and I will not sell you an availability I cannot personally provide.
Owners of systems installed by others who want ongoing support without an initial inspection. I have to know what is actually there before I can be accountable for it.
Sites wanting scheduled industrial maintenance cycles — planned cleaning programmes and thermal inspection rounds are a separate arrangement, because they are recurring site work rather than support.
Scope
What is included, as deliverables rather than adjectives
- 01 Generation review
- Output checked against expectation when you think something is wrong, or periodically by arrangement.
- 02 Fault diagnosis
- Remote first where monitoring allows it, on site where it does not.
- 03 Warranty claims
- Raised with the manufacturer on your behalf, with the paperwork and the follow-through.
- 04 Warranty register
- Every item with its term and expiry date, kept current so nothing lapses unnoticed.
- 05 A direct number
- The engineer who commissioned your system, not a ticket queue.
Most after-sales promises in Pakistani solar are one line in a quotation — "free after-sales service" — with nothing behind it: no response time, no defined coverage, no named person. It costs nothing to write and it is worth nothing to hold.
What I commit to is narrower and actually keepable. The engineer who designed and commissioned your system is the person who answers when you call. Generation checks, fault diagnosis and manufacturer warranty claims are included on projects I deliver, rather than sold to you afterwards as a service contract.
What I do not publish, and why
I do not publish a guaranteed response time in hours. I could — it would read well on this page and it would cost nothing to type. But I am one engineer, and a number I cannot honour on the week I happen to be commissioning a plant in Vehari is worse than no number at all, because you would have made a decision on it.
What I will do is tell you honestly, in the assessment conversation and before you commit, what my availability realistically looks like and what happens when I am on another site. If you need a guaranteed emergency response, you need a company with a standby rota — and you should have one, rather than a promise from me that would not survive contact with a bad week.
Warranties come from the manufacturer, not from me
This distinction matters and is often blurred. Your panels and inverters are warranted by the companies that made them — typically 12 years product and 25 to 30 years performance on tier-one modules, and typically 5 to 10 years on inverters with an extension usually available at the point of purchase rather than later.
What I add is that you get the paperwork, I keep the register with the expiry dates, and I raise claims on your behalf. That is genuinely valuable, because most owners will not chase a manufacturer claim themselves — and a warranty nobody claims is indistinguishable from no warranty.
An installer who implies the warranty is theirs is either confused or hoping you are. Ask whose warranty it is and what happens to it if they cease trading.
What actually goes wrong, in order of likelihood
- Nothing dramatic — output drifts down as the array soils. Cleaning, not a fault.
- An inverter trips and nobody notices for days. This is the expensive one, and it is why monitoring somebody reads matters more than most equipment decisions.
- A string goes down — a connector, a blown fuse, occasionally a failed module. Sharp drop in one string, obvious in data, invisible from the ground.
- Grid-side disturbance causing nuisance tripping. Frequently a settings question rather than a hardware fault.
- Actual module failure. Rare, and this is where the manufacturer warranty and a maintained register earn their place.
Notice that the first four are not equipment failures. Most of what an owner experiences as "the solar is not working properly" is soiling, an unnoticed trip or a single string — which is why after-sales is mostly a monitoring and diagnosis service rather than a repair service.
Systems installed by someone else
I do take on support for systems I did not build, usually where the original installer has become unreachable. It starts with an inspection, because I cannot be accountable for a system I have not seen — and that first visit quite often reveals that the ongoing problem is a design fault rather than a support gap, which is a different and more useful thing to know.
Questions
What clients ask before they commit
- What does your after-sales support actually cover?
- Generation review when you think something is wrong, fault diagnosis — remote where monitoring allows, on site where it does not — manufacturer warranty claims raised and followed through on your behalf, and a maintained warranty register with expiry dates. On projects I deliver this is included rather than sold as a separate contract, and the person who answers is the engineer who designed and commissioned the system.
- What is your guaranteed response time?
- I do not publish one, deliberately. I am one engineer, and a guaranteed number of hours that I cannot honour during a week when I am commissioning a plant elsewhere would be worse than no commitment, because you would have chosen on the strength of it. What I do is tell you honestly before you commit what my availability looks like and what happens when I am on another site. If you need a guaranteed emergency response, you need a company with a standby rota.
- Who provides the warranty on the panels and inverters?
- The manufacturer, not me — and you get the paperwork. Tier-one modules typically carry a 12-year product warranty and a 25 to 30-year performance warranty; inverters typically 5 to 10 years, with an extension usually available at the point of purchase rather than afterwards. What I add is keeping the register with the expiry dates and raising claims on your behalf, because a warranty nobody chases is worth very little.
- Is after-sales support chargeable?
- Generation checks, diagnosis and warranty claim handling are included on projects I deliver. Scheduled physical maintenance at industrial scale — planned cleaning cycles, thermal inspection rounds — is a separate arrangement, because that is recurring site work with crew time attached rather than support. Where something falls outside what is included I will tell you before doing it, not afterwards on an invoice.
- Will you support a system another company installed?
- Yes, starting with an inspection — I cannot be accountable for a system I have not seen. It is a common enquiry, usually because the original installer has become unreachable. That first inspection frequently establishes that the recurring problem is a design fault rather than a lack of support, which is more useful to know than any amount of ongoing service would have been.
- What happens if my inverter fails after the warranty expires?
- You pay for the replacement, and I will tell you honestly whether replacing that unit or reconfiguring the plant is the better decision at that point. This is also the argument for taking the extended warranty at the point of purchase where one is offered — it is usually much cheaper then than the out-of-warranty replacement later, and it cannot normally be bought retrospectively.
Next step
A site assessment, before anything is quoted
It starts with twelve months of your bills and a visit. If the numbers do not justify the work, that is what I will tell you — and you will have the analysis either way.
