Giant Solar Ltd Anmeldelser 

We recently expanded our solar array by adding more Hanchu storage batteries, and the experience was exceptional. Dealing directly with Ray made the entire process incredibly straightforward. He provided expert, honest advice on our project with zero pressure. The installation guy integrated the batteries into our existing system, adding much needed 'earthing' that the original installers had missed, leaving everything completely clean and tidy. The system is performing brilliantly. If you are upgrading your home energy storage, ask for Ray

Swift response, good clear communication and arrangements for visit of their Technician. The technician was on time, skilled and very knowledgeable. He resolved the problem and took time to explain the process and what steps I can take if I had the same issue in the future.

Very responsive. Came out within a few days to look at my nuisance tripping issue on the solar panels. Technician went out and bought the part needed as part of the fallout. No issues since.

Had an excellent experience with Giant Solar, the engineer was early and was very thorough, in fact he went above and beyond as he'd done everything he thought he could do, he'd left and came back as we had an issue with the dongle on the inverter, he tried one final thing to conect the dongle to the router and it worked, more than pleased with his commitment.

I initially rang Octopus and then got some local quotes as Octopus was quoting quite high. When I spoke to Ray he understood that I had done my research beforehand so the discussion was more consultative than "here's what we will do/install".

He understood that I didn't have a suitable location for a battery and agreed to source higher output panels as I wanted to maximise my export as my usage is low. After measuring he found I could get the 8th panel on the roof that other providers said wouldn't fit.

The scaffolders did a great job of handling spanning over the conservatory.

When it came to installation Ray's team worked quickly and got the panels, inverter and related equipment done in two days, while completing a high quality installation. The bird proofing was included and is really good.

The inverter is great, I have an app that allows me to see how much I've saved and what the panels are generating/exporting in real time. It's also a hybrid inverter that allows me to add a battery later if a workable solution becomes available or I get an electric car.

Ray checked in on the system the next day to see how it was performing.

Price was competitive, you might save a little elsewhere but this is a serious investment where you don't want corners cut. All the cabling is straight/tidy (more so than this old house!).

I would recommend Giant Solar to anyone getting solar/battery systems.

I cannot recommend Giant Solar Ltd highly enough. When I was recently in need of solar assistance they came to my rescue, big time!

At the end of 2025 I ran into problems with my solar batteries. They had been installed in 2021 by ESE Solar, a Liverpool-based company. At the end of December 2025 the batteries started malfunctioning. First they ran completely out of charge and then they wouldn’t recharge or hold their charge properly. Not the best start to the new year! I had a solar maintenance plan with ESE so that was obviously where I went for help. Two and a half months later, however, by the middle of March 2026, after raising tickets, exchanging messages, receiving promises of site visits, waiting, waiting and getting nowhere, I was so frustrated that I gave up on ESE Solar.

That’s when I contacted Giant Solar Ltd. Within two days one of their technicians, Nayeem, was in my loft checking out my solar setup and diagnosing the problem. The batteries were dead and needed to be replaced as did the ESE-installed inverter which was faulty and had no doubt caused the initial problem. The equipment was still under warranty but activating the warranties would have to be negotiated with ESE Solar. Having already experienced two and a half months of frustration with ESE, though, I couldn’t hack the prospect of more frustration. So, after talking with Ray of Giant Solar I decided to cut to the chase, ditch the faulty equipment and start again. Forgoing the warranties incurred expense that I could have done without but the batteries and inverter had to be replaced, and I wanted it done sooner rather than later.

Within two weeks Giant Solar had new batteries in place, a replacement inverter installed and all of it connected, and up and running. Customer service as it should be! Now, instead of faulty equipment, endless frustration and uncertainty of service at the hands of ESE Solar, I have functioning equipment, peace of mind and certainty of service knowing that professional, effective and efficient technical expertise and advice is only a phone call away, courtesy of Giant Solar. And with no pesky, impersonal “tickets” to come between me and service. So without hesitation, five stars, huge plaudits and heartfelt thanks on my part to Giant Solar!

We booked a diagnostic appointment and this was arranged quickly on a date/time convenient for us.
We were visited by Naeem who thoroughly checked our full system and identified the fault and gave information re the required action needed to resolve the issue.
Naeem explained everything to me and made sure that I was fully aware of what issues had been found, the impact on our system and the various options open to us....thank you so much for your time, expertise and making everything clear for us
Big thanks also to Ray for the great communication received (email and telephone) ......this company really do care about their customers 😀

Would recommend Giant solar, there service was spot on replacing a failed generation metre, all good now. Very quick response.

Excellent service! My system was installed by a installer which was closed. Giant Solar was invited to fix the issue, and they fixed it in the first visit! 100% recommend

Great support and very quick action. Rehan has gone out of his way to organise in order for our solar power installation back to its full generation capability. Not even minding to get his hands 'dirty'.
Well done Rehan and Nayeem!

Goat Solar went above and beyond to fix an intermittent fault with my father in law’s solar panels.

Comms prior to the call-out were carefully handled and pictures of the installation requested so that Giant could be as prepared as possible to fix the problem.

On the day, Nayeem the technician was very careful to ensure he had checked every part of the PV setup and was very thorough in identifying the intermittent tripping problem.

I should particularly comment that Nayeem was also very patient with my father in law who is 90 and loves to talk! He listened patiently and showed interest in his stories of the solar panels and motorbikes etc.

After checking that the fault was resolved, the technician also looked at the connecting infrastructure into the house and followed up with a very thorough report, with photos, of the installation, fault and remedy.

After the visit we had a follow up call from Giant to check that there had been no further issues. I should add that the cost of the visit seems reasonable bearing on mind the expertise required to understand and fix this technology.

I would have no hesitation is recommending Giant Solar, a company that exhibits the kind of customer service long since forgotten by many.

Found this company on CHEKATRADE so knew they had been checked for accreditations and all work done by them thru CHEKATRADE would be reviewed. They came out to do a Solar Panel Health check. Responded to all communication promptly, turned up on time and reviewed the System. Found no faults. Very Polite People and very reasonable cost for service. Would Recommend.

Giant Solar people are helpful honest and gracious. My installers MyEnergy Solutions being ignored me for two years. Did not supply correct documents for registration. Faults occurred with solar panels system The company cut my calls off. I contacted Giant Solar explain to them what has happened. Rehan with engineer came to fix the problem. I am a pensioner. They were professional with courtesy. I would recommend Giant Solar to anyone who is thinking of having Solar panels system. I understand that Giant Solar does roof insulation and heat pumps and Gas boilers. My fellow pensioners give them a call, chances are you might get it for free. I rate Giant Solar as a TOP company where people matters.

Had a problem with my solar panel meter and they diagnosed it and fit a new meter at the visit. My previous one was dead and I didn’t have to pay for a new meter unless it was needed, which was hood.

Excellent service
We were very impressed by the quality, efficiency and empathy that Giant Solar showed in helping us to solve the problems with our solar batteries. Unlike other companies this small job was no problem for them. Rehane was so professional and helpful, he fully understood our problem, arranged for an engineer to attend our property. On the day of the visit Rehane came with the engineer to make sure everything went smoothly. We are so pleased with the results. Thank you.

What a pleasure to deal with this company. where every person you interact with provides a professional service. This company was recommended by a friend. From the point of initial contact through to full completion we were guided through the products, installation process & completion.
A special thanks to Rehan, for his experience & support from start to finish, answering the many questions we had & working with us to resolve/ put our minds at ease. You are a credit to the company.
Also thank you to the professional installers & the support Team.
We would highly recommend this company.

Company delivers on its promises and got it all sorted within a week before my holiday.
From sale, scaffold, survey and installation was seamless and a company who is meticulous on quality.
Great work and I will recommend Giant Solar to family and friends.
5 stars!
