I'll start by saying I've been in the solar industry for over 14 years now and have never met a more incompetent and shady business operation such as Growth Panel... We were interested in running a marketing campaign for our solar business across the UK and found Growth Panel selling solar leads and digital marketing services so made an enquiry.
I decided to give them a call and the ONLY phone number provided on their website was funny enough a mobile number directed to a young guy (Harry) which matches the Owner of the business on his Linkedin. I thought.. it must be a pretty small company if the Owner himself has his mobile on his homepage taking inbound enquires... Never the less, this in itself would not be a problem, however I asked questions about their service and he failed to answer the most basic questions... He was rude and kept avoiding my questions which was a horrible 15-minute phone conversation and experience overall...
If you're a business looking to make a decision is ask yourself why does a company claiming to be the #1 Solar Marketing Agency for leads in the UK have no Social Media - Facebook Page? How can you spend your customers marketing budget if they don't have a social media presence yourself on the exact platforms you claim to be experts in?
I have never seen a reputable digital agency not have their own business page...
Linkedin Page only has about 4 employees at the time of writing this review... Says you're in business for 2 years, but claim to be the #1 agency in the UK?
This does not seem legitimate and a massive red flag..
This was not all that completely put me off doing business with them.. They were more deal breakers..
On their website they have multiple "Awards" displayed from genuine Reviews sites like Clutch.co, so I contacted Clutch.Co and the company confirms they never heard of Growth Panel and have NEVER given them any Awards, so I showed them their website screen shot clearly showing the award badge and "fake rating" and the person I spoke with at the company said it was Fake and they have not been issued any awards and could not find another review page link to their company anywhere!
Honestly, I still can't get over how Growth Panel UK advertise as the #1 Solar Marketing Agency when they is NO Facebook Page? I have never seen a solar leads agency or any digital marketing agency have ZERO Facebook page and run Paid ads for their clients...
All the reviews here on Trustpilot appear to all be posted within 1 Month as well back around (March 2024).
It's good that Trustpilot is actually a solid trustworthy site and will not allow Growth Panel to remove all genuine reviews and hide mine. Trustpilot is at least ethical and they are happy to show REAL negative customer reviews and feedback...
This is just my personal experience, but businesses should be careful with companies with no social media presence claiming to be the best social media marketing experts in the country with FAKE Awards.
I would Never do Business and highly recommend others spend your money elsewhere.
- Just my two cents.
Be careful!

Growth Panel really helped my business with SEO & get higher in the rankings on Google - would definitely recommend their services.
The lads created a compelling and visually stunning website for my solar business.
It’s generated a lot of traffic which has converted into sales for me.
Great job, would highly recommend them.
Highly recommend Harry and James. Experts in the solar space with initiative marketing strategies.
I'm not the kind to leave a review usually, but this time around i had to stop to give those guys some love.
We needed a rebranding at my solar installation company, because i guess we were doing things the old way. We tried 2 different companies, claiming the moon, but we were disappointed with the results.
That is when Growth panel showed up in the first results of our quest for a relooking. And not only they executed the job flawlessly, but they exceeded our expectations.
This translates into how easy flowing our communication was with the team at Growth Panel. They completely understood the challenges we were facing and suggested an action plan.
Deadlines were fulfilled, promises were kept. The new website helped us ranking in the first page of google search after only a few months. The website looks stunning and achieved greater conversion rate.
To be fair, we'd say it was one of the best return on investment we did this year, as our experience with Growth Panel was efficient, spot on and overall a great value for money.
So bottom line, we recommend to anyone owning a solar business to have a chat with those lads. They really know what they're doing.
We have given the Growth Panel team full control of marketing for our solar business. They have completely re-branded our business, built a seriously professional website and begun lead generation off the back of this.
They have taken the stress out of marketing for us, and we are flooded with enquiries for Solar, Battery Storage & EV Chargers.
The best in the business and we look forward to continuing to work with the team for years to come.
Last year, we realised our website was outdated.
Our conversion rates were dropping and the amount of bugs was causing users to click off.
Something had to change.
Fortunately, a friend (also in the solar game) referred me to Harry and the Growth Panel guys.
Now.. our site isn’t small.
The site build was 15 pages (not a small job to get right!) and they absolutely nailed it.
It’s fast and easy for our customers to use.
They listened to our needs, and designed the site with our specific solar/marketing knowledge baked into it.
They got our brand voice just right, and the site design is GORGEOUS.
The best part?
They got the site built in just over 2 weeks.
The results and feedback tells us everything we need to know.
10% lift in conversion and people telling us how much they love our branding.
The solar game is getting extremely competitive— a slick and fast website is a competitive advantage if you ask me! And the ROI is obvious.
If you want to get ahead in Solar this year, I’d highly recommend reaching out the Harry and the team.
We have so far had a great experience with growth panel and the team especially Harry and James they know what they are on about and have increased our revenue. Thanks guys
Harry and James have excelled in our agreement and have already in a few weeks demonstrated how efficient they are at delivering exceptional results.
It’s an absolute pleasure to work with you guys, looking forward to a prosperous future.
Overall, my experience with growth panel was fantastic! The team was professional, knowledgeable, polite and easy to work with throughout the entire process. They listened to my needs and delivered an outstanding website that exceeded my expectations. The design was visually appealing, user-friendly, and perfectly showcased my business. They listened to everything I wanted and really felt like they cared. Communication was clear and prompt, and any revisions or updates were quickly addressed. I would highly recommend growth panel to anyone looking for a top-notch website.
Very pleased with the website created by Growth Panel. 8k was a lot to invest, but this has been solid investment. I took this to the board of directors (which wasn’t easy to pass), but we’re all buzzed with what was produced. The most noticeable change is speed. This is crucial to solar as leads need to be dealt with fast before they go to competitors.
Harry and his team always go above and beyond. He has an excellent attention to detail, is very thorough in his consultation and exceed our expectations
Brilliant and would recommend to any other solar firms looking for growth
Thanks!!
Really trustworthy company. Pleasure to work with. And have helped us out alot. Have given us free advice and actually care about your success, Feels like you're dealing with people and not some disconnected corporate entity.
Really hold them in high regards.
