"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."

"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."

"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 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."
