When the Tanjent Energy team pulled up to this property in NW London, it was clear this wasn’t going to be a straightforward job — and we wouldn’t have it any other way.

The roof was a patchwork of challenges: a traditional slate pitched section meeting a flat felt roof, a heavily tree-shaded south face, tight scaffold access, and an already-congested garage. Exactly the kind of installation that separates good solar engineers from great ones.
“The south-facing pitch — the obvious choice — was almost entirely shaded by mature trees. So we looked elsewhere.”
Rather than forcing panels onto a suboptimal aspect, the Tanjent Energy engineers surveyed every available surface and settled on a north-west pitched section and the top flat roof. Both offered meaningfully better real-world generation than a shaded south pitch ever could. It’s a reminder that compass direction is just one factor — shading analysis always tells the fuller story.

Getting materials up safely was its own puzzle. With scaffold access limited by the property’s layout, we carefully coordinated our installation sequence to work efficiently within the constraints — no shortcuts, no compromises on safety.

Inside the garage, the challenge shifted to the battery installation. Space was at a premium, and fitting a Tesla Powerwall and its gateway in the conventional side-by-side arrangement simply wasn’t viable. The solution? Tanjent Energy positioned the Powerwall and gateway on opposite sides of the garage — a clean adaptation that kept the installation code-compliant and fully accessible for future servicing.

The result is a system tailored precisely to this home. Not a template dropped on a difficult site, but a genuinely engineered solution. That’s the Tanjent Energy standard.
