The integration of renewable energy technologies into the building
sector is critical for achieving climate and energy targets,
particularly within the framework of the European Union’s
decarbonization policies. Building-integrated photovoltaics (BIPV) offer
a promising solution by enabling the dual function of building envelope
components and on-site electricity generation. However, the widespread
adoption of BIPV faces significant barriers, including high initial
investment costs, design and integration complexity, fragmented
standardisation and a shortage of skilled labour. This study
systematically identifies, evaluates and prioritises the key factors
influencing the implementation of BIPV technologies using a hybrid SWOT
(strengths, weaknesses, opportunities, threats) and Analytic Hierarchy
Process (AHP) methodology. A comprehensive literature review and a
modified Delphi method involving expert input were employed to select
and rank the most relevant factors in each SWOT category. The results
indicate that external factors—particularly regulatory requirements for
energy efficiency, renewable energy adoption and financial
incentives—are the most significant drivers for BIPV deployment.
Conversely, competition from building-attached photovoltaics (BAPV),
high investment costs and the complexity of integration represent the
main barriers and threats, compounded by internal weaknesses such as a
lack of qualified workforce and fragmented standardisation. The findings
underscore the importance of targeted regulatory and financial support,
standardisation and workforce development to accelerate BIPV adoption.
This research provides a structured decision-making framework for
policymakers and stakeholders, supporting strategic planning for the
integration of BIPV in the construction sector and contributing to the
transition towards sustainable urban energy systems
