Very professional throughout, Ray took time to explain the works so everything went smoothly, they arrived and completed exactly as agreed, and went out of their way to make the installation as good as possible. I've no hesitation recommending Giant Solar.

I am struggling to find words to describe how pleased I have been with Giant Solar. From first consultation to final handover we were made to feel like the most important customer that they had. We were asked our opinions and desires with regards to every aspect of system design and equipment placement to best suit our desires. They did everything possible to make the fit look as pleasing as possible, even if it made their work more difficult. I would highly recommend these guys to anyone considering solar power.

The Giant Solar guys gave a really friendly, careful, knowledgeable and professional service from start to finish. Ray was our main contact and he regularly kept me up to date with how things were going throughout. I would not hesitate to recommend them. 1st class service.

Excellent service

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!

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!

Great service from the company! Since my previous installer closed the business, and Giant Solar gave me a reasonable quote, and job was done smoothly and efficiently in their first visit. This saved me from trouble as I got no support from the company who provided the warranty.

This was a difficult job, replacing 15 year old panels, using old rails, and then reconnecting the electrics to the original inverters. The system was checked and is proving to work properly. I didn’t know that inverters wear out, if they fail I will have no hesitation in calling you out to replace them. The team were professional and conscientious. Many Thanks Chris Ball

Goat Solar went above and beyond to fix…

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.

Every step along the way these have been brilliant. Rehan has been my contact all the way through, from quote to after sales. Top man, he even visited the other day (phoning ahead first) to see how we were doing with it. Our setup (10 panels and a battery) is currently on track to make us about £5 profit this August, compared to the £70 bill we had the June before installation. The installation itself was a doddle and the two blokes that did it were hilarious with their bickering. The scaffolding had gone up about three days before and was down within a few days too. Compare this to my neighbours who used a different company and still had their scaffolding up two months later. Can't recommend these enough.

From start to finish had a great experience with Giant Solar. We replaced a broken inverter but took the opportunity to move it to another position. Rehan was extremley knowledgable and popped out to make sure we were getting compatible equipment. Great communications. Technician on the day was amazing, very neat, very tidy and did a fantastic job. Well done guys, you genuinley exceeded expectations.

I had the pleasure of working with Giant Solar to install a solar system and battery for my home, and I couldn't be happier. From the initial consultation, the team was incredibly helpful in understanding my specific needs and designing a system that perfectly suited my requirements. They explained the different options and guided me in selecting the best components for the job. Their expertise and dedication to creating an optimal solution were truly impressive. Throughout the installation process, they were highly professional and efficient, ensuring I understood how the system works and what to expect. I appreciated how they went above and beyond to support me, offering valuable advice on maximizing the benefits of my new system and being readily available to answer questions. Thank you, Giant Solar and especially Rehan, for helping me take a significant step towards a more sustainable future!

I sent an email to Giant Solar enquiring about an additional battery for my solar scheme. They responded within an hour and having ascertained my requirements provided an immediate very competitive quotation. Once I accepted the quotation they agreed to undertake the work within three days. Their Engineer, Nayeem arrived on time and under took the work to an excellent fashion. He went at great length to inform me of all the details and ensure that I fully understood all aspects of the installation. He ensured that he did not leave until he had cleared up all brick dust and any mess leaving everything looking perfect. Three weeks later Nayeem contacted me by telephone as a follow up to ensure that I was totally happy with the equipment and installation. An excellent company which I would have no hesitation in using again or recommending to anyone. Also an excellent and diligent employee.

Health Check on Solar Panel System

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 are friendly and professional. Their customer service is excellent - they followed up our initial enquiry promptly and were able to answer our questions in a clear way. Their technician who installed a new inverter for us worked efficiently, explaining in a straightforward way on what would be happening with the installation. We were very satisfied with the work carried out.

Giant Solar company are helpful honest and gracious where people matters. My installers MyEnergy SolutionsLtd ignoring me for two years. The company installed the solar panels system 21st September 2023 didnot supply the correct documents for registration with National Grid. Sending grid wrong information. Faults occurred with the solar panels system. I contacted them by watsup email and phone calls and by Facebook. The company cut my calls off. With Check a Trade I contacted Giant Solar and explained to them what has happened. Rehan came with the engineer came to fix the problem. I am a pensioner. They were totally professionals and courteous. I would recommend Giant Solar to anyone who are thinking of having solar panels system installed. I understand that Giant Solar heat pumps and Gas boilers. My fellow pensioners give them a call. Chances are that you might get it for free. I rate Giant Solar as a TOP company where people matters. They are always available when there's a issue with solar panels system. Giant Solar will NEVER IGNORE YOU. Giant Solar are treating as a valued customer.

What a company!!! Absolutely fantastic, service brilliant. When speaking with them I felt that they were genuine, to the point that before making a visit they ran through a series of questions to make sure nothing simple had caused the problem. When the technician visited he was very pleasant, clearly knowledgeable and soon identified the problem and the fix. It was a pleasure to deal with this company A+++

Solar meter problem quickly resolved

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.

We were very happy with the service we received from Giant Solar Ltd, they were prepared to help us when others had sought to try and sell us unwanted or unnecessary items costing a lot of money. Some were not prepared to help with a small job. Thank you to Rohan for making the process seamless and professional. We would definitely recommend them to others.

Excellent service

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.

Also thank you to the professional installers & the support Team. We would highly recommend this company.

Excellent! Left in the capable hands of Giant Solar and nothing but praise to the Company. Sale to Install carried out within 2 weeks and a professional manual recieved within a week, so was able to start claiming export sooner than expected. Speedily service but with attention to detail and always there to help.

I made it clear from the beginning that the workmanship and presentation is very important for me as I am in the process of renovating my home. I must say, it exceeded my expectations. With mixed information from different installers, it was a daunting process to begin with, but I’m so glad I went with Giant Solar. A stress free journey with very competitive prices. Great knowledge with experienced installers and no long winded sales pitch either. Straight to the point! It started to rain but the installation team kept on working. I want to thank the Support Team and Installers for its efforts and highly recommend Giant Solar. Not many companies like this around.

Such a professional Company. Really happy going ahead with Giant Solar. They helped me with my export registration and kept me updated throughout with a beautiful presented Handover Pack. The installers were polite and kept me updated at each stage with no cutting corners. Great tutorials and the App works great with all information in real time. Many don't bother once they have taken your money but Giant Solar were prompt with their updates after installation. I am well pleased. Thank you!
