Joju Solar

May 2024 had a 2nd Powerwall installed and upgraded to the Gateway 2 from 1. From start to finish everyone involved was knowledgeable, professional and helpful. Dec 2018: Very helpful and knowledgeable company. Installed a Tesla Powerwall 2 into our existing PV installation, plus a Zappi charger. Very neat, tidy and well supported installation.

We used Joju Solar to install solar panels, 2 Tesla batteries and a Tesla Gateway for us. They did an amazing job from start to finish. Such a lovely company to deal with and very passionate about what they do. I wouldn't hesitate to recommend them . Very knowledgeable as well with a very informative website which is continually updated. Wonderful to deal with such a friendly company that had answers to all my questions.

JoJu solar recently installed 11.2kWp of solar on my roof, and two tesla powerwall batteries. Our aim was to cover off our consumption of electricity in the summer, and reduce it in the winter, with a high summer usage due to a hot tub we run May to September. With an idea of some additional production to be able to operate EV in the future. JoJu were one of 4 firms we had quote, and they weren’t the cheapest, but they quickly understood our needs, they understood what we wanted to do, they didn’t make assumptions and get cookie cutter products out and try and sell them to us, we had one supplier obsessed with our “high summer usage” and how that was unusual, JoJu just got on with it and worked with us. We worked together to design a system that meant we could make maximum use of our produced solar, but also could cope with storing the potential levels of Solar, due to the house having roofs facing mostly east and west we couldn’t have loads of panels facing south, so went with having panels on both roofs, something that came about with an onsite survey, JoJu’s technical chap that came to site looked at the roof, looked at where the sun landed, looked at the existing electrical supply, and made useful suggestions – they were the only people that came to site and looked at the existing electrics! Our system is designed with growth in mind, we’ve got a 10kWp inverter, we’ve got the extra DC cables in the roof and we’ve got a design for adding additional panels to the garage, small bits of thought now which will save a lot of headaches for us and them in the future! We’ve got 2 powerwalls so we can absorb all the power from solar into the batteries, we can turn on the oven, the dish washer, the kettle all at once and not end up pulling from the grid as we’ve gone over the output of a single powerwall, the powerwall inverters can deliver it all – and giving us options to load shift in the winter and make use of products like octopus agile. JoJu showed their knowledge in their recommendations, they offered different products and explained the benefits of each, they helped us make decisions for the right reason between cost, features and look. Most importantly they kept us up to date all the way along the process, always happy to explain if we had questions. Their roofers and electricians did a great job, they were tidy, they were knowledgeable, they worked hard, they got the job done and they took pride in what they did, they worked out solutions to problems along the way, and we’ve come out of it with a very tidy install that looks very aesthetically pleasing. I wouldn’t hesitate but to recommend JoJu Solar, they have been a pleasure to work with, we will be back to look at additional panels and EV chargers in the future with them.

Excellent service throughout. It's thirteen days since the Powerwall was installed, and we haven't used any grid electricity since then. None. Every member of staff, both office and at installation were people I would be glad to have as friends, and I don't say that lightly.

Joju installed solar on my pitched and flat roofs. They listened carefully to the goals of my project (house rebuild) and proposed 2 possible solar configurations. They were easy to work with and the panels look great. I can't wait to activate them in the next few days!

Garbage

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

Zero sales pressure, good result.

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.

5 stars for a great company

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!

Engagement with Joju Solar

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.

Absolutely brilliant. Faultless service. So lovely to deal with

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!!!
