The increasing use of electric vehicles (EVs) presents a great chance for the building sector to adopt green methods and incorporate renewable power sources into construction. Building-integrated photovoltaics (BIPV) provides a way that not only produces clean power but also improves the visual appeal of structures. This article examines the architectural innovation in BIPV for EV mobility, looking at its uses, technical progress, difficulties, and prospects.

Uses of BIPV in EV Mobility

BIPV systems can be used in various ways to support EV mobility:

  • EV Charging Stations: Perhaps the most typical use of BIPV is seen in carports or parking shade structures with PV panels built directly into them. These structures provide a clean and renewable source of power for charging electric vehicles, reducing dependence on fossil fuels and aiding the reduction of carbon in the transportation sector.
  • Parking Structures: BIPV can be built into parking structures, providing shade and generating electricity to power charging stations and lighting. This creates a sustainable and energy-efficient parking setting.
  • Building Fronts and Roofs: BIPV fronts and roofs can generate electricity to power EV charging stations located within the building or in nearby parking areas. This allows buildings to become net-zero energy structures and support the growing demand for EV charging setup. A smart and logical application of BIPV in suitable areas is an important and clear step to achieve net-zero energy buildings.
  • BIPV Roofs for EV Charging: Studies have indicated the competitiveness of BIPV roof solutions in several European countries, including France, Switzerland, and Germany. These systems, with a typical capacity of 7 kWp, a 30° tilt, and a south direction, have shown positive net present value (NPV) due to various revenue streams, such as feed-in tariffs, investment support, and VAT reduction/exemption, in addition to savings from self-used electricity.
  • Photovoltaic Windows and Solar Windows: Photovoltaic windows and solar windows integrate solar cells within the glass used in windows, allowing light to pass through while generating electricity. This inventive approach maximizes the use of building surfaces for power generation while keeping natural light and transparency.

Architectural Innovation in BIPV Front Design

Architects and designers are finding inventive ways to build BIPV into building designs, creating visually appealing and functional structures. A crucial part of maximizing the value of a BIPV system is planning for environmental and structural factors in the early stages of the architectural design. Some examples include:

  • Photovoltaic Windows: Solar cells can be built into glass fronts and windows, allowing buildings to generate electricity while keeping natural light and transparency.
  • Solar Roof Tiles: BIPV roof tiles smoothly integrate solar technology into the roof design, providing an aesthetically pleasing and energy-efficient substitute to traditional roofing materials.
  • Solar Covers and Carports: BIPV can be used to create solar covers and carports that provide shade and generate electricity for EV charging in parking lots and public spaces. These structures not only serve a practical purpose but also improve the visual appeal of the surrounding setting. Charging stations are no longer mere utilitarian structures; they are becoming architectural landmarks that smoothly blend with their surroundings.

Technical Progress in BIPV for EV Charging

Recent progress in BIPV technology has further improved its efficiency and combination with EV charging systems:

  • Two-way Charging: This technology allows EVs to not only take power from the grid but also send it back, turning them into mobile energy storage units. This can support grid stability and provide backup power during outages. Two-way charging transforms EVs into active participants in the energy system, enabling them to both take from and supply power to the grid or homes.
  • Clever Charging Solutions: Clever charging systems optimize the charging process by considering factors such as electricity prices, grid demand, and user preferences. This can reduce costs and pressure on the power grid.
  • Fast Charging: Progress in charging technology has led to quicker charging times, making EVs more convenient for everyday use.
  • Wireless Charging: Wireless charging is an inventive technology that allows EVs to charge without wires through charging pads embedded in the pavement. This technology gets rid of the need for physical cables and connectors, making EV charging more convenient and user-friendly.

Difficulties and Prospects

Building BIPV into EV charging setup presents both difficulties and prospects:

Environmental and Economic Benefits


Using BIPV for EV charging offers significant environmental and economic benefits:

Environmental Benefits

  • Reduced Greenhouse Gas Emissions: BIPV generates clean power, reducing dependence on fossil fuels and lowering carbon emissions.
  • Improved Air Quality: EVs charged with BIPV-generated electricity produce zero tailpipe emissions, adding to cleaner air quality.
  • Sustainable Transportation: BIPV supports the move to sustainable transportation by providing a renewable power source for EV charging.

Economic Benefits

  • Reduced Energy Costs: BIPV can significantly reduce energy bills by generating electricity on-site.
  • Increased Property Value: Buildings with BIPV systems can have higher property values due to their energy efficiency and sustainability features.
  • Financial Benefits: Government benefits and tax breaks can further improve the economic benefits of BIPV.
