10.  High variety of BIPV applications are
possible.
 For each of these applications, multiple
BIPV products exist on the market,
with their own specifications.
 In the segment of residential buildings,
cold roofs are the most common BIPV
installations.
 In the segment of commercial
buildings, façade BIPV systems are
much more common, as well as BIPV
skylights.

 Historical BIPV market grew
significantly from 2008 to 2011.
 This can be explained by generous
support schemes for BIPV.
 BUT the definition of BIPV applied in
those years is incomparable to today’s
definition.
 The modification and/or disappearance
of these incentives caused the BIPV
market to sharply slow down.

 Main markets: France, Netherlands,
Switzerland, United Kingdom.
 All BIPV segments are expected to
grow.
 In particular, the residential
segment is expected to lead the

 In 2021, the BIPV market should
represent a total value of more
than 600 M€ at least.
 It could pass the 1 B€ threshold in
2022, and the 1,5 B€ by 2023.
 This steady BIPV market growth
should be led by cost reductions,
increased customization
possibilities, and a pressure to
improve buildings’ sustainability.

14. Stakeholders’ overview
 There is no market-pull: usual
actors of the construction sector
have only a low interest in BIPV
adoption.
 Policymakers also have a
tremendous influence on the
adoption of BIPV, but only have a
medium interest.
 Difference in both interest and
influence between building
occupants and building owners,
which can hinder the process.
 New actors with both skills in
construction and PV have a strong
influence as they could bridge the
knowledge gaps.

15. The value proposition
of BIPV can seem
blurry, especially due
to the cost gap with
conventional PV and
construction
materials
Lack of knowledge &
resistance to change
within the building
sector, creating
difficulties to
collaborate
Lack of standardized
product qualification

strategies can be
more cost‐efficient to

16.  Design technical systems that favour an easy reparability
and replaceability of components
 Think modular and prefabricated to reduce costs
 Develop standards combining both electrical and
construction features
 Consider BIPV as early as possible in the development
process
 Support digitization of procedures

18. What is competitiveness for BIPV?
 Construction component
 Construction system
 Electricity generating unit
 Investment

19.  On average, BIPV roof components are
more expensive than conventional roof
construction elements
 In many cases, the cheapest BIPV
products can come at a lower cost
than high-end conventional
construction materials (e.g. slate tiles)

20. Cost evaluation of
BIPV: as a facade
construction
component
 On average, BIPV facade components
are more expensive than conventional
facade construction elements
 Yet, the cheapest BIPV products can
come at a lower cost than high-end
conventional construction materials
(e.g. stone)
a‐Si‐based curtain wall – Average component cost
c‐Si‐based curtain wall – Average component cost
CIGS‐based ventilated facade – Average component
cost

21. Cost evaluation of
BIPV: as a roof
construction
system
 Most conventional roofing solutions
can be challenged by BIPV solutions.
 In particular, the BIPV solutions based
on “in-roof mounting systems” can be
very competitive
 Tailor-made BIPV solutions are more
expensive but can provide the
advantage of a better aesthetical
integration, and possibly additional
building-related functionalities.

22. Cost evaluation of
BIPV: as a facade
construction
system
 BIPV façade systems can be
competitive with some conventional
systems, in particular high-end
systems.
 Average façade system costs are based
on a wider range of costs due to the
variety of projects’ characteristics (size,
complexity, type and thickness of the
modules). a‐Si‐based curtain wall – Average system cost
c‐Si‐based curtain wall – Average system cost
CIGS‐based ventilated facade – Average system cost

23. Total cost and revenue of ownership
approach
This approach allows to determine whether an investment in a BIPV system is
attractive or not, compared to investing in a competing conventional building
envelope solution
REVENUES
* Initial investment
Extra cost of BIPV compared
to a conventional
construction solution
* Operation and
maintenance costs
* Savings on the
electricity bill for self-
consumed electricity
* Excess electricity fed-
back to the grid

[€/m²] ;
When positive, it indicates that it is worth investing the
extra costs associated to the BIPV system since they will
be compensated by the extra revenues

 Allows to compare easily and rapidly

25. Typical residential rooftop
‐ Installed BIPV capacity : 6‐8 kWp
‐ Surface covered by the system : 50 m²
‐ Annual self‐consumption rate : 30%
BIPV tiles
In‐roof mounted conventional PV system
Roofing BIPV solutions in the residential
segment are globally already competitive.
Generated electricity largely covers the
marginal extra cost due to BIPV and even
generates revenues of more than 200€
per installed square meter of BIPV (over
the entire lifetime of the system), in the
case of an “in-roof mounting system”.

residential BIPV

26. CIGS ventilated facade
c‐Si ventilated facade
Typical commercial facade:
‐ Installed BIPV capacity : 36‐41 kWp
‐ Surface covered by the system : 270 m²
‐ Annual self‐consumption rate : 90%
Compared with BIPV systems on roofs:
 non-optimal irradiation conditions on the
façade
 substantially higher than average end user
costs
The Netherlands & France:
 Quite low compensable retail electricity
prices
 Less optimal irradiation than in southern
European countries
Italy:
 High irradiation
 Relatively high retail electricity prices.
Switzerland:
 BIPV specific direct incentives
 Relatively generous feed-in premium.
