Reviews

4.9

TJS Solar is named as the installer across a wide range of solar and battery jobs. One reviewer reports significant problems: a design that fell from 36 panels to 29, communication dropping off after the deposit, staff arriving hours late, and handover documents with wrong system sizes and a non-existent fourth string, with corrections only made after the reviewer spotted them. That reviewer also says the handover documentation and MCS certificates were held back until final payment, and that the complaint had still not been resolved after months. Many other reviewers describe the installation teams as polite, tidy and informative, and say they kept them updated through the work. One reviewer says the scaffolding company was unhelpful and the scaffolding was still up 10 days after installation.

Significant issues with system size, documentation and aftercare I engaged TJS Solar for a residential solar and battery installation in early 2026. The original design and quotation were for 36 panels. When other installers raised doubts about whether 36 panels would fit, I was reassured by TJS that they would “prove them wrong.” In the end only 29 panels could be installed. After the deposit was paid, communication dropped off noticeably. On delivery day TJS staff arrived many hours late with little prior notice, and I had to help unload the panels myself. The final invoice correctly applied a contractual reduction for the missing panels. The bigger ongoing problem has been the official MCS handover documentation. Multiple versions of the handover pack contained clear errors, including incorrect system size figures and a phantom fourth string in the commissioning reports (when only three strings exist). The Single Line Diagram still did not properly show the Sigen Gateway that provides the backup/island capability I specifically requested. Corrections were only made after I repeatedly identified the problems myself. The handover pack and MCS certificates were also withheld until the final payment had been made. I have spent many months trying to resolve these issues through direct contact with TJS, then via MCS and later through Green Homes Dispute Resolution / RECC. Progress has been slow and the matter remains unresolved at the time of writing. The roofers who attended were professional and helpful. However, the overall experience with sales assurances, post-deposit communication, documentation accuracy, and complaint handling has been poor. Prospective customers should carefully check the detail of any quotation, ask for written confirmation of what will be delivered, and be prepared to scrutinise the handover pack thoroughly.

The installation teams of Mike and Warren did a really great professional job and the standard of equipment installed is excellent.

Tony came out to complete the survey and answered all of our questions. TJS were recommended via a neighbour whose friend had used them. We were happy to go with a recommendation and also supporting a local company was important to us. The workmen who came to complete the installation were great - really polite, informative and respectful. They worked neatly and cleanly and tidied up after themselves. The system was installed and Ryan checked it was functioning correctly, showed us the SIGEN app and answered any questions. We would recommend TJS without hesitation. Our only frustration is with the Scaffolding Company who, despite us explaining we were going away on holiday and really wanted it removed before in order to access our garage, were very unhelpful and 10 days after installation, 5 days after we left for our holiday, still have not taken it away. I would advise TJS to consider this when engaging a scaffold company as it could unfairly reflect negatively on them.

Initial consultation was in-person and everything about configuring the system, how it would be built and payments to be made were explained in understandable language. Installation was quick and efficient and the system is now humming away nicely
