Building-integrated photovoltaics
Building-Integrated PV (BIPV)
Building-integrated photovoltaics (BIPV) treat solar as a material of the building itself: the roof, a façade, a glazed element or a canopy that also generates electricity. We design and specify residential BIPV for architect-led projects and contemporary self-builds.
What building-integrated PV really means
BIPV — building-integrated photovoltaics — describes solar that does a building's job as well as generating power. Rather than sitting on top of a finished surface, the modules are the surface: the weathering layer of a roof, the cladding of a wall, the glass of a canopy or rooflight.
It is a different discipline from bolting panels onto a completed house. A BIPV element has to satisfy the architecture, the building envelope and the electrical design at the same time, which is precisely why it belongs in the drawings from an early stage rather than being retro-fitted at the end.
Where BIPV earns its place
- 1 Contemporary self-builds where the roof or a wall is a deliberate architectural surface and framed panels would undermine it.
- 2 Glazed elements — canopies, verandas, brise-soleil and rooflights — where semi-transparent PV glass provides shade and generation together.
- 3 Extensions and outbuildings whose form is being designed from scratch, so the generating surface can be resolved as part of the composition.
- 4 Projects pursuing a strong sustainability narrative, where visible, considered integration is part of the point.
Designed in, from the drawings out
We work from the architect's intent. Whether you bring us a concept, a set of planning drawings or a fully detailed package, we resolve the PV as a building element — junctions, weathering, fixings and cable routes worked through so the installed result matches the render.
Because BIPV terminology is used loosely across the industry, we are careful to specify exactly what a system is: a genuine integrated element, not a framed panel described as integrated. That clarity protects both the design and its performance.
Frequently asked questions
What is the difference between BIPV and ordinary solar panels?
Ordinary panels are mounted on top of a finished roof or wall. Building-integrated PV replaces the building element itself — the roof covering, cladding or glazing also generates electricity — so it has to be designed as part of the fabric rather than added afterwards.
Is BIPV only for commercial buildings?
No. Commercial BIPV — façades and large canopies — is more visible in the market, but the same principles apply to homes. We focus specifically on residential and architect-led BIPV, which is far less well served.
When should BIPV be considered in a project?
As early as possible. Because integrated PV forms part of the weathering and structural design, it is far easier and cheaper to resolve at concept or planning stage than to introduce once a roof or façade has been detailed.
