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!
