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 projekct with zero pressure. The installation guy integrated the batteries into our existing system, adding much needed 'earthing' that the oroginal 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

I cannot recommend Giant Solar highly enough. From the initial quotation through to installation and commissioning, the whole process was professional, straightforward and completely stress-free. Ray was excellent throughout. He took the time to answer every question honestly, explained the options clearly without any sales pressure, and was always available when I needed advice. Great work, thank you.

My solar panels had stopped working after I had spray foam insulation removed. Giant Solar where very efficient, and professional in diagnosing and fixing the fault. And went above and beyond in their service. A pleasure to deal with, they clearly care about their work and their customers.

At the end of 2025 my solar batteries and inverter malfunctioned. The company responsible for the initial purchase and installation weren’t too interested in helping fix the problem. After two and a half months of frustration, I ended up contacting Giant Solar Ltd. Within two days one of their technicians, Nayeem, was on site. Two weeks later new upgraded batteries were in place and a replacement inverter had been installed. Problem fixed! So, ten stars to Giant Solar, particularly Nayeem and Ray, for their prompt, professional, effective and efficient technical expertise, advice and service.

No sooner was my job listed than Giant Solar of Wolverhampton were in touch. Details were exchanged, a deposit was paid and within two days one of their technicians turned up and completed the job very efficiently. I was absolutely delighted with the service that was provided.

Excellent, prompt, professional service. Couldn’t have asked for more. Good communication throughout the job and excellent technical prowess. Would I recommend Giant Solar Ltd? Absolutely. No hesitation whatsoever! Five giant stars.
