Well designed and carefully installed system
I spoke to a number of installers before choosing TEMS. What set them apart was the level of engineering detail in the proposal. Rather than a high-level quote, they provided a properly considered design with panel layout across multiple roof faces, MPPT allocation, structural and wind loading calculations, and a clear explanation of how the system would be configured. It gave confidence that the design had been properly thought through, not just priced up.
My system isn’t straightforward (four roof faces, dual inverters). I made some key design choices myself, including SMA equipment and a north-facing array, and TEMS worked through the implications to ensure everything would perform as intended.
The installation was done to a high standard. One example that stood out was how they handled an issue with the roof tiles. The hidden ridges meant the initially planned rail clamps weren’t a good fit. Rather than push ahead with something suboptimal, they took the time to source a more suitable mounting solution that worked properly with the tiles. That approach summed up the job as a whole: careful and considered, not rushed.
They’re not the cheapest option, but that’s reflected in the design, communication, and installation quality. If you want a system that’s been properly thought through and installed with care, I’d recommend TEMS.
