Building Integrated Photovoltaics: Gravitating Towards Green Technology

Energy & environmental issues have been a major concern these days. To cope-up with such issues, the photovoltaic system was invented in 1970s. Later, in 1990s, a major upgrade was seen in the solar & photovoltaic industry. The photovoltaic panels were designed in such a way that it could be installed into the building envelope, offering dual functionality. Popularly known as Building Integrated Photovoltaics system, the AEC stakeholders could leverage their benefits for both, aesthetics as well as for energy generation in a building structure. However, the BIPV modules were not so popular at first due to the inadequate efficiency it offered for the cost. Gradually, the scientists and engineers started working on the module and were successful in upgrading the systems which offered a leap of benefits over the conventional photovoltaics & BIPV systems. Ultimately, the efficiency of the Building Integrated solar systems was increased with a considerable reduction in its cost. Still, the scientists are working on to upgrade the photovoltaic system in order to provide maximum efficiency to the users, with a significant decrease in its manufacturing cost.

What Is Building Integrated Photovoltaics?

Building Integrated Photovoltaics or BIPV is a modern day upgrade to the conventional solar cells or the solar systems, for generation of electrical energy from the solar energy. The BIPV technology in construction enables the production of energy on-site, transforming the users from energy consumers to energy producers. It extensively uses the solar energy and converts it into the electrical energy which can further be transmitted to various houses, offices, buildings and so on, as per their requirements.

Building Integrated Photovoltaics is somewhat similar to the conventional solar systems as it functions in the similar way for the production of electrical power from the solar energy, which is available in abundance. BIPV, however, serves the architectural industry as well as it fulfills the aesthetic requirements of the building. Unlike traditional solar panels, the installation of the BIPV panels is not just restricted to to the rooftops. Instead, they can be installed in the envelope of the building i.e the roof, facade and windows, as well, like regular glass panels which offers an aethetically pleasing view to the exterior of the building or an apartment.

What Are The Major Functions of A BIPV System?

The Building Integrated Photovoltaic solar systems mainly serves the following purpose:

• Aesthetics – The BIPV module are installed in the exterior part of the building, which is known as the envelope. Like the glass cladding, the Building Integrated Photovoltaics panels ensure appealing exterior aesthetics of the building.
• Energy Generation – The photovoltaic system generates adaquate amount of electrical energy from solar energy to fulfill the energy requirements of the building. The emergy generated by the photovoltaic cells is environment friendly. Hence there is no harm to the environment also.

Benefits of BIPV

Building Integrated Photovoltaics offer a plethora of benefits to the Architecture, Engineering & Construction (AEC) Industry. Let us explore the advantages of incorporating the BIPV solar system in a building, as given below:

• Compared to conventional solar systems, BIPV technology is more effective with an ability to produce more electricity while taking up less area. Scientists are still working on the BIPV panels and systems to enhance its effectiveness and reduce the cost as well.
• Since Building Integrated Photovoltaics do not contaminate the environment, they are an environmentally beneficial technology.
• If you employ BIPV in the building or in your business, it has a good effect on your organisation.

Disadvantage of BIPV systems

The use of BIPV technology in building design possess a few drawbacks which are likely to be considered when installing the system.

• The cost of the system is its biggest drawback. The cost of the system depends on how much energy the system can generate and how much energy the building requires.
• Some structures require a lot of energy, while others only require a small amount. In addition, BIPV technology has an impact on the building's design. The BIPV system is installed on a roof and needs room. In order to endure heavy winds, it also needs a lot of room.
• Weather dependence, a longer rate of return on investment, decreased efficiency, etc. are other significant negatives of the BIPV system which can be taken for consideration.

Wrapping-Up

While the initial cost of a building integrated solar power system is high, one must also consider the cost-benefit ratio it will provide over its entire lifespan. With proper maintenance, you can expect solar panels to last for a considerable amount of years. Installing a BIPV system in your building can thus help you achieve your sustainability goals.
