This was a fairly complex project - five properties in total with two electricity meters. We had solar panels fitted with Naked Solar 8 years ago so I contacted them again for a second set of solar panels and 3 batteries. I also went out to a couple of other suppliers for quotes. Naked Solar were the only company who came back to me and were happy to deliver on such a complex job. It's been done so swiftly and efficiently. I've worked with several members of the team and found without exception that they are knowledgeable, professional, polite and fun. Special mentions to Zoe, Matt, Neil, Luke, Cav, Gary, and Reece. Thanks so much!

We recently had 19 solar panels and a Tesla battery installed by Naked Solar and couldn’t be happier with the service from start to finish.

Communication throughout the whole process with Zoe was excellent — everything was explained clearly and thoroughly, and we always felt well informed. The reporting and documentation provided were detailed and professional, which gave us real confidence in the installation.

The installation team were polite, tidy, and respectful at all times, and the whole project ran smoothly and seamlessly from beginning to end.

We would highly recommend Naked Solar to anyone considering solar and battery installation.

After a couple of disappointing experiences with other suppliers, it was refreshing to discover Naked Solar.

From the first conversation with Joe, through to the survey, installation and follow-up, the service has been exceptional.

They take care of every detail, and the installation team were punctual, tidy, and completed all the work to a high standard.

Our system (20 panels and 18kWh Sigenstor battery storage) is already saving us a small fortune, and will save more once we get registered for grid supply.

I can't recommend Naked Solar's accounts and installation teams enough, and would be delighted to provide them with a glowing reference at any time.

We recently had solar panels fitted and the whole experience was excellent from start to finish. Everything went smoothly from day one, from the initial setup and communication to billing and installation.
The team was very professional throughout, and the installation was carried out efficiently with great attention to detail. It’s clear they take pride in their work.
We would highly recommend this company to anyone considering solar panels. An amazing company to deal with!

Designed and installed my PV and Battery system. With there being so many choices and options they were great. They talked me through each option and explained the advantages and disadvantages of each. The installation went smoothly except for a few technical issues but they stayed until it was working as expected. They arranged the scaffolding and even replaced the broken tiles when they took it down. They are not the cheapest but you do get a quality job with minimal fuss. Overall a great company to deal with and I highly recommend them.

Naked Solar were great to deal with from start to finish. Jake took the time to understand what we were wanting to get out of battery storage and once we'd decided to go ahead the installation team were great. They didn't leave until they'd thoroughly explained the system to us so we understood how it all worked. A great experience all round.

Brilliant from start to finish, we've just had 16 panels installed on our garage and we could not fault Naked Solar.

Zach was our first contact with Naked Solar and he took us through the options we had. He discussed what our views were on technology, length of guarantees we would be looking for and what it is we actually wanted to use solar for - we had time to think / debate and from that he outlined options and we then made a decision in our timescales.

We then had a site visit and Naked Solar came up with a detailed plan and refined cost once the exact details were worked out such as cable lengths / routes within the house etc. We discussed various options and came up with the one which would work best.

Dates were sent for the installation and we had conformation on the scaffolding installation dates. The engineers arrived when planned, as did the scaffolding guys. Everyone knew the plan and they got on with it. All the engineers / electricians were good and a particular shout out goes to Rhys who did most of the electrical work. Frankly, I was dreading some sort of upheaval with all the wiring going in and it was painless. He even arranged the order of what he was going to fit around us.

He explained the technology and got us logged in / set up and we were eagerly waiting for sunrise the next day to see the solar in action. Throughout they were keen to ensure that we were happy with what they were doing and we were and remain so.

Very impressed with the whole Naked Solar team. An extremely professional organisation from the face to face Teams discussions to the technical advisors on a pergola structure being created just to carry solar panels. Nobody was pushy or trying to steer us towards a specific product, they worked with us establishing a budget and advised on a range of ideas which would work for our individual project.

I had naked solar install 16 panels with solar skirt and 2 Tesla power wall 3 batteries. After install I asked about adding 4 more panels. They was more than happy to accommodate me and was installed really fast and work was done to a very high standard. I would recommend naked to anyone looking for solar install and battery installs very professional and kept me updated on everything that was happening.

You can't fault this company, nothing is too much trouble. Everything is explained thoroughly and whoever you deal with is polite and helpful. From everyone involved ,scaffolders/solar installers/electricians/office staff ,they are all so helpful and polite. They also tidy up each day. If we could we would give 10stars! Would definitely recommend this company.

We looked around at various companies before using naked and we are very happy we chose them.
Very local to us which is obviously great. Price wise comparable to everyone else but the service levels from initial calls to information and installation were excellent. Everyone we spoke to or met at the house were polite, professional, friendly, knowledgeable and just generally seemed to care about what they were doing.
Our roof provided some difficulties for them but they got it done, overcame problems and finished to a high standard.
Thanks so much to you all.

Highly recommended. Did a really professional over the air diagnostic job on a faulty Solar Edge installation, successfully transferred the ownership of the system, fixed the problem and arranged for the Solar Edge to cover the cost via their warranty. Brilliant service, and they're local. 100% recommend.

🌞 **Exceptional Service from Naked Solar – Highly Recommended!**

We recently had solar panels installed by Naked Solar while undergoing a roof replacement, and we couldn’t be more impressed with the entire experience. From start to finish, Naked Solar demonstrated professionalism, flexibility, and outstanding customer care.

One of the standout aspects was their willingness to coordinate directly with our roofing company. This ensured the scaffolding met both parties’ needs, streamlining the process and saving us time and hassle. Their proactive communication made a potentially complex project feel effortless.

Now that the system is up and running, we’re thrilled to be enjoying complete self-sufficiency with our electricity. While registration with the grid takes a few weeks (so we can sell surplus energy), Naked Solar guided us through every step. The only minor downside is the standing charges, but they will reduce once we switch to a new Octopus contract post-registration.

The installation team were friendly, respectful, and kept us informed throughout. On the admin side, communication was timely and clear, and everyone we dealt with was incredibly knowledgeable.

If you’re considering solar, we wholeheartedly recommend Naked Solar. Feel free to reach out if you have any questions—I'm happy to share more about our experience!

We’ve just had our solar panels installed by Naked Solar and the whole experience has been excellent. From start to finish everything was handled so smoothly. The team were professional, friendly and clearly cared about the details — they even cleaned out our gutters while they were up there, which was such a thoughtful touch. The scaffolders were polite and respectful, and the installation itself was neat and tidy.

The panels are already performing brilliantly and we’ve seen huge savings on our bills. It’s a great feeling to be generating so much of our own clean energy and to know the system is working exactly as promised.

Naked Solar have been fantastic, and we’re more than happy to recommend them to anyone considering solar.

Naked Solar did a really professional job. They talked us through the options and helped us select the right equipment. The panels look sleek on the roof and they hid the wiring well. On sunny days we are completely self sufficient and our electricity bill is £0, plus we can sell our excess energy to the grid. Fantastic company from start to finish.

Naked Solar have just increased the capacity of my solar PV system to 25kW. The process was an absolute pleasure from beginning to end. Communication at all stages has been prompt and the can-do attitude of their admin and sparkies was so refreshing!
My only regret is with myself - for not getting them to do the initial PV installation in the first place! In future, if I need ANY related work to be done, Naked Solar will be my first choice.

Very pleased with my naked solar experience. Ollie was very helpful in the early stages of going through designs and pricing up several different quotes as well as being a helpful contact for updates throughout. Ben provided the design exactly as I wanted tailored to my needs. On the day of install the roofers Josh and Nathan were punctual and polite and happy to go about their work. Tom the electrician was also very polite and helpful going through the installation. I have no doubt that the install team took pride in their work. All the people I have dealt with during this process have been great and I would definitely recommend naked solar.

Nothing was too much trouble; questions were answered with enthusiasm and a high level of product knowledge.

The installation team were amazing and took great care to make sure that the job was done perfectly and were a pleasure to have in our home. Above all, it was so refreshing to work with a team of people who clearly love their job, the company that they work for and care about the product they are selling - what a great team!

We chose Naked Solar to install our PV panels and battery on the day that we met the company as they impressed us so much. From the outset, Kristie worked with us and our designer Ben to work out the best package for us, including several redesigns so that we could compare the differences. We are heavily reliant on electricity in our home and have two EVs to charge so the right combination of PVs and battery was crucial. We never felt rushed, and questions were answered quickly during, and after, the design phase. All of this was managed exceptionally well by Kristie. The overall quality of workmanship by the installation team was exceptional. Great care was taken to install the system with the least damage/disruption at the house. The controls were installed in our utility room that had been recently decorated and how Rhys, our electrician on the install, managed to do the work without a single mark on the walls was remarkable. Similarly, the team of installers, Carlos, Zach and Harry managed to cause minimal disruption, even in the immediate aftermath of Storm Darragh, to carry out a fantastic job. Thank you all for your patience and respect shown to us throughout the planning and installation. We would be very happy to recommend, without reservation, Naked Solar and wish you great success in the future.

I cannot recommend Naked Solar enough. They are a great team of professionals, none of whom are pushy at any point in the process. I was on the fence with installing panels and a battery, had no idea about the pros and cons, options available etc. Over a period of months (yes I took quite a while to think on it!) Kieran & Jack handled every query of mine, educated me, projected different scenario outcomes for me.

Eventually I landed on a package that I felt was right for me and my home, at which point the wheels were set in motion. The scaffolding went up, the scaffolders were punctual and efficient, then a few days later the installation took place. It took just less than 2 days for 10 panels and a battery to be fitted. It was working immediately and the guys showed me how to use the app to monitor and control the settings. I'm immensely pleased with the products and the standard of installation.

If I have any constructive feedback it would simply be that there was some confusion over whether a trench would be needed between the house and the garage. From what the Naked Solar electrician said to me when he arrived, it would always have been needed - so a brief call between the head office and the electrician would most likely have solidified that sooner in the process for me. As I needed to dig the trench, it would have been ideal to know a bit sooner that it would definitely be needed.

I am a big fan of this firm and would recommend them to anyone in the South West looking into Solar technologies.

Naked solar were great to deal with. Very personal response to all enquiries, and lots of details provided regarding the cost/benefit over time of the solar installation they proposed for us. I was impressed at how bespoke the assessment of solar potential for our property they provided was at the quote stage. Would highly recommend them.

My experience of Naked Solar was outstanding from beginning to end.
Everything was completed to a very high standard and the work ethic of everyone involved was second to none.
Particular thanks must go to Jake who discussed the initial options with me and was very patient while I got my head around the multiple choices available to me.
On the day of installation Carlos and Gary arrived on time and completed the roof installation in an efficient and considerate manner. The two electricians, Gary and Tom were both exceptional ensuring that all their work met my expectations and that everything was as I wished.
Without exception they were all very polite and friendly and cleared everything up after themselves.
I have no hesitation in recommending Naked Solar as a Company as their attention to detail and the care of their employees is second to none.
Thank you all for your help and I look forward to having you work on my house again when I expand the system.
Kind regards,
Nigel Flitton

Excellent pre installation advice and information. Arrived on time and installed with the minimum of fuss. After installation, the service was equally good and totally attentive to all of our questions. Looks good and works as advertised.
Many thanks.

Quite simply, the best company I’ve ever worked with. The pre-sales service, communication, installation, and electricians were all excellent from start to finish. Nothing was ever a problem and the whole system was installed perfectly within the timescales discussed. The whole system is working well, and we are already discussing future options. Nice work and a great team, thank you very much.
