Reliable and Trustworthy
Great service from Green Team One. Communication throughout the process was spot on. We had plenty of notice as to what was happening when. The team took the time to explain the design, the benefits of the equipment and were accommodating to minor changes - while working hard to ensure we understand all the output rates that the different changes made. Overall fantastic service and we are very happy - no hesitation recommending.

A first class service
We finally decided to take the plunge and fit solar panels. I had spoken to a few salesmen in the past but Allan from Green Team One stood out as friendly, helpful but above all knowledgable and was able to answer all my questions and concerns. The team of electricians and roofers were all very friendly and efficient and the whole job was carried out in one day with very little disruption. The handover on the day was clear and helpful. Allan will return the following week to check we fully understand the system. I would strongly recommend Green Team One to anyone in the Tewkesbury area who is thinking of fitting solar panels.

Green Team One - are all you need.
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.

Green Team One solar panel sytem
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.

Excellent service
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.

Solar and Battery, Top System from Top Company
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.

Great work no hassle
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.

Brilliant!
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!

Outstanding service for home battery system in Cardiff
We went with Green Team One to add a home battery system and new EV charger to our existing Solar Edge PV array in Cardiff - and are so glad we did. The service was excellent - they warned me at the start that they didn't chase or push for sales (and that sometimes meant we would have to chase them!) but I personally liked that attitude after we'd experienced the opposite from others we'd had quotes from. The efficiency they showed meant we had our whole system installed and working within 3 weeks of my enquiry. Tom came to assess the site then Brindley and Josh completed the installation. All were incredibly helpful, polite, efficient and professional and then to follow up Rob came out (on a weekend!) to check we were happy with everything and the system was operating well. We have been so excited to see the battery using our solar power to minimise our grid power (even in a cloudy February!) and we've been given some great advice on how to optimise the system for our lifestyle. I would absolutely recommend them, and I'd say their values and mission are values actually lived by the company from what we have experienced. Oh - and the quote was the most competitive too!

Installation of solar panels, battery & EV charger
Green Team One recently installed Aiko solar panels and GivEnergy battery & EV charger at my house and I can highly recommend them. After speaking with several installers, Rob and his team were the frontrunner for their technical knowledge, attention to detail, personal touch, non-pushy sales approach, and willingness to go above & beyond. The installation itself went very smoothly and the electricians & roofers were friendly and left the house tidy. I'm confident I made the right choice with Green Team One, and that they'll be available for any support in future if needed.

Fantastic service - great advice and install
Green Team One just completed our PV install at our house in North Bristol, having completed a similar install at my sister's. They were absolutely fantastic at every stage, the technical advice at the start was comprehensive, the offer was the best combination I had (giving the best final overall net output) and the quality of the installation has been fantastic, from the scaffolders to the electrician and roofer. Plus the after-service has given me a lot of confidence with using the panels and getting on the right tariff. Would strongly recommend to others

I was recommended Green Team One by a neighbour who said their workmanship was high quality and that they had an eye for detail. I can echo that opinion and add to it. They were friendly, fast and accurate, and they talked through all the various options thoroughly and patiently. Solar plus storage is a complex product because the peak power isn?t as important as total energy, but the latter is hard to visualise. The company explained how their proposed design would meet my needs without forcing it on us. I?ve had several helpful messages from them since about the operational aspects and the performance of the hardware has been excellent so far.

We had Aiko solar panels, GivEnergy inverter and battery installed by Green Team One in October 2024. From the initial consultation with Rob, through to the final invoice being paid, Green Team One were a pleasure to deal with. Rob was very thorough and explained how different systems worked, what would work best for us, and tailored the solution to fit our needs. Tom was extremely helpful whilst going through the installation plans and worked with us to find the best route for cabling etc. The installation happened as expected and when promised. I would 100% recommend Green Team One.

Green Team One installed 16 solar panels, an inverter and battery at our property. We originally had another 4 companies quote for the work but they didn't fill us with confidence and failed to fully explain how we could best use the solar to our advantage. Rob spent time with us, explaining the system and advantages clearly and answered all our questions. He was (and still is!) always happy to answer calls and emails from us if we have any questions. The install went very smoothly, all the team we met were very professional and spent extra time with us to ensure the install met our requirements and that we were happy. Afterwards Rob visited us again and talked through the system and explained how to update the settings to best benefit from exporting/importing power as required

Rob arrived to discuss what I wanted from the solar installation. He made some suggestions as to the best solution and we agreed on the number of panels and battery size. A couple of weeks later, the scaffold arrived and the following week the team turned up to fit the system. The team from green team one were very considerate and completed the work with the minimum of disruption. Tom went through the app and showed how the system was set up and how to make some of changes to this once I have the export tariff set up

Green Team One installed solar panels, battery and an inverter for us. We would recommend them to anyone considering a solar system. Rob Johnston and his team were friendly, highly efficient and made a point of ensuring they provided us with best advice to meet our requirements. They also advised us on tarrif options so that we could secure the best import and export tarrifs for our system. Customer care is a priority for them and they visited us after commissioning our system to ensure it was working effectively and efficiently. I have no hesitation in giving Green Team One a five star rating!

14 solar panels installed by Green Team One Ltd. We are very pleased with the whole process. We had appreciated personal visit by Rob with a detailed explanation before a quota was sent. We came with more questions and enquiries later, which were all patiently answered. Installation itself was quick, with no hassle, and with the great attention to detail. Post installation visit provided us with more useful information and advice. Generally very good experience.
