What Are BIPV Tiles

Introduction of BIPV tiles

Building Integrated Photovoltaic (BIPV) systems represent a specialized segment of photovoltaic (PV) technology that involves the integration of energy-generating elements directly into building components. This innovative approach allows building materials to fulfill their traditional construction functions while also generating energy. Unlike conventional systems that require separate mounting structures and allocated space for solar panels, BIPV seamlessly incorporates PV modules into the building envelope. The growing demand for cost-effective PV installations has spurred the development of multifunctional PV products that serve as both building materials and energy sources. BIPV offers several advantages over Building Applied Photovoltaic (BAPV), including lighter weight, enhanced aesthetics, superior wind resistance, and direct incorporation into the building’s design.

BIPV products utilize a variety of photovoltaic cell technologies, which can be broadly categorized into crystalline and thin-film types. Crystalline cells are further divided into two main categories: monocrystalline, known for their higher efficiency, and polycrystalline, which offers slightly lower efficiency. Both types can be customized in various shapes and levels of transparency to meet specific design needs. BIPV applications are diverse, encompassing building roofs, shading systems, external walls, façades, skylights, PV canopies, and balconies. Key multifunctional aspects that drive the use of PV products in architectural design include:

Architectural aesthetics

Light and visual considerations

Sun protection

Thermal insulation

Thermal control

Weather protection

Sound insulation

Recent innovations in BIPV have resulted in the development of various products used in building construction, including foils, tiles, roof slates, thin-film roofs, bifacial cells, dye-sensitized or semi-transparent cells, and solar cell glazing products, alongside traditional PV modules.

BIPV systems can be configured as either grid-connected or off-grid installations. This article will focus on grid-connected BIPV systems, with an overview of their basic structure illustrated in the accompanying figure.

Types of BIPV system

In-roof solar panels

Roof-integrated solar panels function similarly to traditional rooftop panels, but they replace a section of roofing tiles and serve as the primary roof covering. Many people appreciate the aesthetics of these roof-integrated panels, as they align seamlessly with the rest of the roof structure. While roof-integrated photovoltaic (PV) systems are typically about 5-10 percent less efficient than conventional rooftop PV modules due to reduced ventilation, their design appeal makes them a popular choice for new constructions and renovations, where they have proven to be quite effective.

Complete solar roof

Extending the concept of integrated panels, you can eliminate conventional roofing altogether and have a completely solar roof. Specially designed modules can be used to cover the entire roof area, with dummy panels used where generation is not possible.

Solar tiles

If conventional panels have an unsightly appearance, solar tiles may be the way to go. PV units that mimic traditional roof tiles are indeed a growing area, and some amazing products are already available. Whether your entire roof is covered with PV or dummy tiles, you will not be able to tell the difference.

Thin-film solar

Thin-film is a type of solar module widely used in BIPV systems. It's made up of extremely thin layers compared to traditional crystalline materials, resulting in a material that can be used on curved surfaces or semi-transparent facades. Thin film therefore performs better in low light, high temperatures or unfavourable angles.

Solar facades

Most large multi-storey buildings incorporate curtain walls or facades to maximise energy efficiency or design. With the added effect of free, renewable energy, BIPV facades will fulfil this function. While they can be made from crystalline panels, thin-film solar is typically used at vertical angles and in the shade because of its superior efficiency, as the sides of tall buildings are usually vertical and often shaded. The multi-layered nature of BIPV materials also allows it to provide acoustic insulation when used as a building envelope.

Solar glass

Replacing conventional glazing with solar glass to generate energy where roof space is limited, as is often the case in multi-storey buildings. Solar windows and skylights are available in a range of colours and can be fully opaque or up to 50% translucent. As well as generating electricity, solar glass has the added benefits of minimising glare and improving thermal insulation - all of which are critical in large office buildings. PV glazing reflects infrared light, which reduces heat transfer through the glass. This helps to keep heat out in summer.

Coloured panels

Coloured panels can be designed to match existing buildings or for a specific aesthetic. Traditional colours are crystalline blue/black and thin film brown/black, but layers of coloured laminate or glass can be used to achieve alternative colours. Colouring the modules results in a 5% reduction in production.
