I recently had 18 AIKO 465w NEOSTAR solar panels and a Tesla Powerwall 3 installed at my home by Green Team One, and I couldn’t be more pleased with the experience. From start to finish, the team delivered an exceptional end-to-end service that was both professional and seamless. A special mention goes to Ryan, who handled the panel installation with precision and care. His attention to detail ensured everything was installed perfectly with minimal disruption. The electrical team—Bryn, Josh, and Ellis—were equally impressive. All three were incredibly professional, polite, and tidy throughout the process. Their work was methodical, neat, and performed to a high standard, which left us feeling reassured and confident in the final setup. The installation not only looks great but is performing flawlessly, reflecting Green Team One's commitment to quality and customer satisfaction. It’s rare to find a company where every member contributes to such a high level of service—and Green Team One clearly sets that standard. Highly recommended for anyone considering solar solutions.

I recommend Green Team One to anyone looking to go solar. The whole process from quote to installation went swimmingly smooth. I'm really impressed with the neat and tidy solar panel installation by Ryan, Josh, and Ellis. They were awesomely professional and very helpful from start to finish. They showed up on time and completed the job in less than a day! No glitches, the system fired up and is powering my house with solar-generated energy. They just got on with the job. They're a credit to Green Team One and earned their KFC.

Rare honesty.
I asked for an opinion and advice. They were excellent, absolutely unbiased and this meant that I didn't change my current solar panels nor add a battery as the savings would have been negligable - such honesty is so rare these days. Many thanks

To do a reinstall of a battery storage system

August 21st 2024 I commission an online company (not Greenteam One)to add a battery storage to an existing solar array. They came up with a very attractive quotation so I awarded them the contract. The installation was not only dangerous but failed to meet the warranty for the givenergy products, and other essential regulatory requirements,worse was their abject refusal to correct the work. After a long battle and with the help of my bank I was able to get a significant refund from this rogue company. A very painful and worrying experience. Greenteam one got to hear about my appalling experience and offered to do a complete reinstall of the equipment, which i agreed. What a difference, the professional approach, attention to detail, consideration given to me my property and equipment was first rate. I now have a system that is safe and fully compliant with regulations and warranty. I cannot recommend Rob, Tom and Greenteam one highly enough. An excellent company that deserves to succeed. Thank you, you will always get my recommendation. Be very careful with online companies always go by recommendation.

I used this company to install 2 solar panel arrays together with associated switchgear and battery. From planning through installation to commissioning they were professional, knowledgeable and always courteous. Even the scaffolding sub contractor was quick, polite and efficient.

After many hours researching the world of domestic solar solutions we narrowed the search to three companies for quotes. Not only was Green Team One’s quote the best value proposition, the solution is by far better with a 16 panel 7.04 kWh array, an 8 kWh inverter and a 10.2 kWh battery which maximises the roof generation potential. Personally I usually only complete a review when I get exceptional service and the experience from making the initial contact, the meeting on site with Rob, the following survey, the organisation behind the scenes and the installation team, Green Team One has been exactly that, exceptional. A fantastic team of people with very high and detailed knowledge of solar, passionate about what they do and how to support their clients. There is absolutely no hard sell, they will not press you for an order when they meet you. Rob gave us several ideas and options which were easy to understand and thus help us decide the solution best suited for our needs. From placing the order, all was installed and producing power in just 5 weeks. The office team were extremely helpful no matter how many times I pestered them! The on site teams were all polite, very efficient and the installation is neat, tidy, professional and above all working really well. Our thanks to everyone at Green Team One for an enjoyable experience from a company we would trust to complete further installations should we need them in the future.

Prompt efficient service from initial sales calls and visits, through installation and after sales. The whole process has been simple, low hassle, I hardly noticed the team working on the day of the install. Would highly recommend to everyone. Very happy here in Gloucester with my solar panels and battery, looking forward to a sunny summer.

Absolutely thrilled with the service from Green Team One, from start to finish. Rob spent about an hour at our home, clearly explaining the best solar system for our needs—no pushy sales pitch, no pressure, and no follow-up hounding. Although their quote was slightly higher than a competitor’s, Rob gave us genuine confidence that he’d deliver top-quality products and service—and he absolutely delivered on that promise, and then some. Throughout the process, we interacted with at least 10 different team members, and every single one was professional, knowledgeable, and clearly took pride in their work. It’s rare to see that level of consistency and care across an entire team. Highly recommend!
