Electech is, hands down, the best customer experienced I've had from a small trader/builder. I found them via Trusted Traders and the whole experience, from beginning to end, has been outstanding. They helped me design the system as I wanted it, answered my questions, made their recommendations and respected my decisions,. To top it all up, they even provided the best quote! The installation (13 solar panels + Powerwall 3 + extension pack) went smoothly. They ran the unusually long cable exactly the way I wanted it, left everything tidy - except for a few cable ties here and there :-) - and it all worked beautifully from day one. They also spoke directly to Tesla when I complained that the battery wasn't behaving the way I wanted. The Tesla team provided a quick update to the software and it's all perfect now. A few weeks after the installation, Tom from their support still replies to me almost immediately whenever I message him with a question or concern. An additional nice detail: they originally quoted for 14 panels and without considering that the cable would need to be longer than usual. Still, when only panels fit on my roof, they discounted the price of the panel from the invoice. No questions asked. Well done to the whole Electech team.
