Joju Solar Reviews 62

Positive : Have used Joju for several projects, the installation in the past has been excellent and support great. However….

Negative : Something seems to have changed on the customer services side, they installed a car charger for me last September, I have been chasing them to finish the job / fix a couple of small things / pay them the balance of the invoice… Ive emailed phone calls etc etc... no response despite promises of a call back. I also asked for a quote last year for an unrelated solar inverter replacement, again no response.

Hopefully someone from the company will read this review and come back to me. Perhaps they are now concentrating on corporate customers big projects only ?

Did a good job of installation a few years ago but absolutely zero customer support afterwards. Impossible to get a response from them. Useless.

Installation was fine in 2021 but aftercare has been abysmal. A faulty Tesla battery was voluntarily replaced by Tesla but Joju tried to make us pay for the installation, which is its obligation under the Consumer Rights Act. After thee months of emails and legal letters, they finally relented. Now, I have been trying for three months to have the old battery taken away. Emails and calls are unreturned.

Garbage. I enquired 2 years ago and never got a response. Now I get spammed every week with another marketing email.

Zero sales pressure. Unlimited patience with my many questions. Worked with me rather than just for me to arrive at the optimal configuration and the right products.

We spoke to a few different solar panel providers and got different estimates. Joju came recommended to us by a friend and once we spoke to them we never looked back.

They gave us a competitive price, were excellent at communicating the whole way through and fitted the panels on team with a team of fitters who could not have been more friendly and helpful.

Our panels have been up and running for a month now and we are still pleased with the whole experience.

We are 100% satisfied and always happy to recommend Joju as a result!

I first engaged with Joju Solar in February 2023 when I had solar panels installed at my house in London. As it faced directly east-west I was able to benefit from panels fixed on both the front and back of the roof, seven each side making 14 in total. Being a sole occupier and thus a low user of energy I decided at that time not to opt for a battery. Although that meant that at certain times of the day I was dependent upon drawing power from the Grid, overall the income that I generated over a year from the sale of surplus solar power exceeded that charged to me by my provider for electricity supplied when my requirements could not be covered by the solar panels. The system provided by Joju Solar proved to be very cost effective.

In early 2025 I moved from London to the north of England. My experience with the solar panels at my London home informed my decision to have them installed at my new home. My very positive experience with Joju Solar back in 2023 made this Company my first choice to advise on, plan and install the system.

I am delighted to say that my confidence in my choice of installer was fully justified. My experience from the initial survey stage, through planning, to installation was a pleasurable experience. The new house also faces east-west, so I opted once again for panels on each side, but was able to accommodate ten on each slope making 20 in total. I also decided this time to have a battery. Although the new installation was much larger and included a battery, the overall cost was not significantly higher than the system I had installed in London in 2023. This was largely reflected in a dramatic reduction in the cost of batteries, and the removal of VAT on both batteries and panels.

Since the new system was commissioned in early August I have been entirely self-sufficient in electricity, and a healthy surplus has been exported to the Grid. As the days shorten the daily surplus is expected to reduce. It is too early to predict an average return for a year, but on present performance I anticipate being self-sufficient throughout the annual cycle.

So far as the installation is concerned, JoJu Solar’s teams worked with consideration and courtesy. I was able to liaise with a project co-ordinator who took personal responsibility for the management of the installation from beginning to end. The installation team fulfilled al their obligations in relation to time and the quality of the workmanship was excellent. Questions were answered both courteously and in detail.

I have no hesitation in recommending JoJU Solar.

We had our solar system installed by another provider and we sat waiting for no help for 4 months. I contacted Joju who had us up and running within 24 hours. We lost 4 months of delicious solar energy but I am so impressed with the professional service we got from Joju. Delightful to deal with and they really knew their stuff. Thoroughly recommended!!!

It has been six months since our installation with Joju, and we have nothing but praise for them. We took out time to decide on what we wanted but they never rushed us and we're really pleased with the results. They were professional throughout the design and installation and thus far it has all gone well. The aftercare has been good and we would have no reservations about recommending them.

Excellent advice and communication throughout the project. All aspects well managed, deliveries and execution all on time and to schedule. Full and complete handover with all documents and guarantees. Staff and contractors were friendly and helpful leaving the site tidy and all waste removed.

Second time we have used Joju. First was for the initial solar and battery install, and was very happy with the process and the final results. So when our pre-existing EV charger was playing up, it made a lot of sense to back to Joju to have them install a replacement and get it fully integrated into the system. Installer (Adam) was very contentious and personable, and kept power down-time to an absolute minimum. Respected our time and property, and install was clean, professional, and am very happy with the result. Doubt we will use them again, as hard to see what else we could add, but will certainly (and have) recommend them to other people wanting a solar install.

JoJu are very happy to take your money for a solar installation but if things go wrong as they have with my Solax batteries and inverter on a couple of occasions it is next to impossible to get them to respond and resolve. There is no point in installing an expensive system if you won’t stand behind your installation work. I’m still waiting for them to resolve a second issue with my inverter and batteries and despite constant chasing - still no resolution I’m afraid

Domestic installation of solar panels, Tesla Powerwall 3, myenergi Zappi and Eddi.

Superb cusomer service before, during and after the installation. Everything happened when expected and the quality of the install is exceptional. Minimal disruption, tidy cabling and overall an outstanding attention to detail and quality.

Could not recommend more highly.

I recently had the pleasure of working with Joju Solar to install a solar energy system at my property, and I couldn’t be more satisfied with the outcome. The system comprises 19 Aiko 470W panels and a Tesla Powerwall 3, installed across three aspects of my house and atop my garden office.

From the very beginning, the project was handled with exceptional professionalism and expertise. I was particularly impressed by the proactive approach of Asha Ponsford-Maguire, who visited my property on very short notice. She spent several hours meticulously measuring and checking everything before I was even committed to anything. This level of dedication stood in stark contrast to other companies that provided generic quotes based on computer simulations and pressured me to make a quick decision.

Joju Solar truly cares about its customers. While some companies seemed uninterested in listening to specific requirements, offering only “cookie-cutter” solutions lacking attention to detail, Joju took the time to design and implement a system truly bespoke to my property. This personalised approach makes perfect sense, as each property has unique characteristics that should be considered.

Special thanks to technical lead Adam Butler and every member of the installation crew. The technical challenges, particularly installing panels on the garden office and routing cables through the entire garden, were managed flawlessly. Their craftsmanship and dedication to excellence were evident throughout the project, making the experience refreshing in an industry where such commitment is increasingly rare.

The Tesla Powerwall 3 has proved to be an excellent choice, offering simplicity and high efficiency without the need for additional inverters. Its built-in hybrid inverter serves as the central hub for all DC and AC conversions, providing ample capacity for future expansion. The Aiko panels have also exceeded expectations with their high efficiency and impressive shade handling, making them a perfect fit for my setup.

None of this would have been possible without the exceptional planning and organisation led by project manager Ben Smith. The complex logistics, including scaffolding and scheduling, were managed seamlessly, resulting in a smooth and efficient progression. The carefully planned milestones, checkpoints, and dynamic adjustments throughout the project made the entire experience stress-free.

Overall, I am thoroughly impressed by Joju Solar’s expertise, professionalism, and commitment to customer satisfaction. They provide bespoke solutions tailored to individual needs, setting them apart from others in the industry. I highly recommend them to anyone considering a solar installation.

I had solar panels with a Tesla Battery installed about 12 month ago and this was installed without any hitches and has been working excellently ever since. Octopus who are my energy supplier have recently introduced a Flux tariff which I decided to take advantage of. To set it up I contacted Joju and Ben Smith a Senior Project Manager took me through it step by step. Being over 70 technology is somewhat of a challenge but Ben was very patient and with minimum fuss I have now got the system working with the new tariff. What amazing after sales service by Joju Solar.

Working with Joju on the installation of our solar system was easy. From the start, their designer was knowledgeable and professional. Our project manager and installation team were also highly professional and efficient. They were responsive to our needs and communication was excellent throughout. We’re very pleased with our system and would recommend Joju as a partner.

Joju Solar worked with my wish list and presented the practical answer. Able to answer all technical questions. Their Project Manager then worked with us enabling late specification changes to be achieved. From start to finish we knew where we were and what was possible. All the roofers and electricians took pride in their work. Tidy and considerate, they worked hard to get the job done, with care and to a high standard. The system working as expected. Couldn't ask for a better installer. Thank you.

Joju took on my project when 3 other companies had turned it down, because of shading and roof pitch. It's working a treat and outperforming my main south facing roof.

Very professional. Top quality workmanship and great after sales care.

Had a GivEnergy battery fitted recently, following earlier Joju solar installations (10 years ago and 18 months ago). Great advice and excellent project manager and installation team
