Quick Facts
What BIPV is
Building Integrated Photovoltaics (BIPV) are photovoltaic products designed to replace conventional construction materials in the building envelope. Instead of installing standard solar panels on top of a finished roof, BIPV uses solar-generating tiles, shingles, glass, or panels as the actual roof, facade, or other building surface. The photovoltaic function is integrated into the building material, rather than added to it.
The category covers a wide range of products. Solar facades use opaque or semi-transparent PV glass as exterior cladding. Solar roof tiles and shingles look like conventional tiles but generate electricity. Solar skylights combine daylight and electricity generation. Solar canopies and pergolas serve as outdoor shading structures that produce power.
BIPV is distinct from BAPV (Building Applied Photovoltaics), which is the term for solar panels mounted on top of existing buildings (conventional rooftop solar). BAPV is what most Indian rooftop installations are. BIPV is a smaller but growing premium segment.
Categories of BIPV products
Solar facades and curtain walls: Photovoltaic glass-glass modules replace conventional curtain wall glazing. Modules can be opaque (full solar generation) or semi-transparent (partial daylight transmission). Used in commercial office buildings, atria, and architectural facades.
Solar roof tiles and shingles: Small PV elements designed to look like clay, slate, or asphalt tiles. Tesla Solar Roof is the best-known international product. Indian manufacturers offer their own solar tiles for premium residential applications.
Solar skylights: Photovoltaic glass replaces conventional skylight glazing, providing both daylight and electricity. Used in commercial atria, malls, and institutional buildings.
Solar canopies and pergolas: Photovoltaic panels integrated into outdoor shading structures such as parking shades, walkways, and rooftop terraces. Hybrid use case between BIPV and conventional rooftop.
Solar windows: Semi-transparent PV glass replaces conventional windows. Efficiency is lower than opaque PV because most of the light must pass through for daylighting.
Solar parapets and railings: Vertical PV panels integrated into rooftop parapet walls or balcony railings, capturing oblique sun without requiring rooftop space.
Indian context
The BIPV market in India is small but growing. Drivers include premium architecture in commercial and institutional projects, sustainable building certification (IGBC, LEED, GRIHA), and the growing focus on net-zero energy buildings.
A few specialised Indian manufacturers and importers serve the market. Vikram Solar, Adani Solar, and Premier Energies offer BIPV products in their portfolios. International players such as Onyx Solar, Issol, and AGC Solar serve premium projects through Indian distributors.
Notable Indian BIPV installations include the CEPT University BIPV facade in Ahmedabad, several IGBC platinum-rated office buildings in Bengaluru and Pune, and pilot solar tile installations in residential premium projects.
Government policy currently treats BIPV the same as conventional solar for net metering, subsidy, and DISCOM applications. ALMM-listed BIPV modules qualify for residential subsidy under PM Surya Ghar.
BIPV versus BAPV
| Factor | BIPV | BAPV |
|---|---|---|
| Role in building | Replaces building material | Added on top of finished building |
| Cost per kWp | 2 to 4 times higher | Standard |
| Aesthetic integration | High | Lower (visible mounting) |
| Energy yield per kWp | 60% to 85% of optimal | 90% to 100% of optimal |
| Installation timing | During construction or major renovation | Retrofit anytime |
| Roof or facade options | Yes | Roof only |
| Available area | Whole envelope | Roof only |
| Custom sizes | Common | Standard sizes only |
For most Indian projects, conventional BAPV remains the better economic choice. BIPV is selected when architectural integration, premium aesthetics, or net-zero building requirements justify the cost premium.
Costs and economics
BIPV CAPEX ranges from Rs 90,000 to Rs 200,000 per kWp installed, against Rs 45,000 to Rs 65,000 for conventional rooftop solar. The premium reflects custom module sizes, integration with building structure, glass-glass construction, and lower production volumes.
When BIPV replaces a conventional cladding material that would have cost Rs 4,000 to Rs 8,000 per square metre, part of the premium is recovered through avoided cladding cost. Net additional cost is typically 50% to 100% above conventional rooftop solar.
The economic case for BIPV is rarely standalone IRR. It usually involves a combination of energy generation, architectural value, sustainability certification points, and building owner brand preference.
Indian use cases
Premium office buildings in Mumbai, Bengaluru, Delhi, and Hyderabad using solar facades to support net-zero or LEED platinum certifications.
Institutional and academic buildings (universities, research centres) using BIPV as both an educational demonstration and an architectural feature.
Premium residential bungalows in Delhi-NCR, Mumbai, and Bengaluru using solar tiles to maintain traditional roofline aesthetics while generating electricity.
Commercial atria and skylights at malls and corporate campuses using semi-transparent PV glass.
Hotel and hospitality projects using BIPV canopies, pergolas, and integrated parking shades.
Heritage building solar projects where conventional rooftop installations would damage the building’s historical appearance.
Common mistakes
Specifying BIPV without considering the building’s orientation and self-shading. BIPV facades on north-facing walls produce little energy.
Comparing BIPV CAPEX to conventional rooftop on a per-kWp basis without accounting for the building material it replaces.
Underestimating the design coordination effort. BIPV requires architect, structural engineer, MEP consultant, and solar EPC to work together from early design.
Choosing BIPV products without verifying long-term warranty support. Some BIPV products from boutique manufacturers have limited service networks.
Forgetting the impact of partial shading on BIPV facades from adjacent building elements (cornices, sun-shades, balconies).
Best practices
Engage the BIPV specialist during the architectural concept phase, not after the building is designed.
Specify ALMM-listed BIPV modules for subsidy eligibility under PM Surya Ghar where applicable.
Use shading and orientation analysis specific to the BIPV surfaces, since they often deviate significantly from solar optimum.
Coordinate with structural and waterproofing consultants to ensure BIPV products meet building envelope requirements.
Document the BIPV system’s specifications, warranty, and maintenance access for the building owner and future renovation teams.
Standards and references
BIPV products must meet IEC 61215 (design qualification) and IEC 61730 (safety), the same as conventional solar modules. Building integration must also meet the relevant National Building Code (NBC India) provisions for facade cladding, roofing, glazing, and fire safety. Specialised BIPV standards under IEC TS 63163 are emerging for products that bridge building and solar codes.

Key takeaways
Building Integrated Photovoltaics (BIPV) replace conventional construction materials with photovoltaic equivalents, integrating solar generation into the building envelope. The category spans solar facades, roof tiles, skylights, canopies, and windows. CAPEX is 2 to 4 times higher than conventional rooftop solar, justified by architectural integration, sustainability certification, and net-zero building requirements. The Indian market remains small but growing, with applications concentrated in premium commercial, institutional, and high-end residential projects.
