Quick definition
A standard solar installation sits on top of your existing roof, held up by racking. BIPV skips that step entirely. The solar cells themselves are built into a product that replaces the roofing, siding, or window material outright, so the solar function and the building material are the same physical piece.
Solar shingles are the best-known residential example, but BIPV also includes solar facade panels and solar-integrated skylights used mostly in commercial buildings.
At a glance: BIPV products typically cost meaningfully more per watt than standard racked panels, largely due to lower per-unit efficiency and higher manufacturing complexity.
Why it matters
Most homeowners choosing solar aren't thinking about aesthetics as their top priority, and standard racked panels are the cheaper, more efficient, more widely available choice for the vast majority of installations. BIPV exists for the segment of the market where appearance genuinely matters more than squeezing out the lowest cost per watt, which is exactly why the Department of Energy has noted that despite being commercially available for over a decade, BIPV adoption has been slower than predicted. For the numbers behind BIPV (building-integrated PV), the solar panel calculator in our System Sizing section walks through the calculation step by step.
Historic districts and strict HOA communities are a common example. Some historic preservation boards won't approve a visible racked solar array on a street-facing roof, but will approve solar shingles that read as a normal roof from the street. In those specific situations, BIPV isn't a luxury upgrade, it's sometimes the only path to installing solar at all.
The tradeoff is real, though. BIPV products generally cost more per watt and often produce less power per square foot than standard panels, a cost driver NREL's own residential BIPV pricing analysis breaks down in detail, since some of the engineering goes toward making the product function as durable roofing or siding material, not just a power generator. Anyone weighing BIPV should compare that tradeoff honestly against a standard system rather than assuming the integrated look comes free.
Where you'll see this
The BIPV building integrated PV cost estimator gives a starting price range for a BIPV installation based on your roof size.
If you're weighing solar shingles against a standard racked system, the solar shingle vs traditional panel cost comparison tool lays out the real cost and output difference side by side.
This term comes up most in historic district and HOA-restricted solar projects, in new construction where roofing and solar are being planned together, and any time a homeowner asks specifically about solar shingles. The higher upfront cost is worth weighing against what it actually nets out to after incentives, using the savings with ITC applied calculator to see the after-credit picture.

Frequently asked
Solar shingles are the most common residential example of BIPV. They replace standard roof shingles entirely rather than sitting on top of them, which is exactly what defines the BIPV category.
Usually yes, often significantly more per watt of capacity. Part of that premium reflects the added roofing or facade material cost being built into the product, but BIPV still typically costs more than standard panels plus separate roofing material bought individually.
Appearance is the main draw. BIPV products, especially solar shingles, look far closer to a normal roof than a standard racked array, which matters to homeowners in historic districts, HOA-restricted neighborhoods, or anyone who simply prefers a low-profile look.
Generally, no, not per square foot. BIPV products often have lower efficiency than standard panels of the same physical size, since some material and design tradeoffs go toward achieving the integrated, low-profile appearance instead of maximizing raw output.
