Here are the case studies of the different BIPVs that are located all over Asia
Skylight BIPV
In the Daito University, Itabashi Campus,there are installations of Solar Panels within the building facades in which it actually put it at an advantage where they can produce energy at any time of the day.
The university uses Skylight BIPV. By using Skylight BIPV, the amount of sunlight that comes into the building is quite a fair bit where it can provide and reduce the bills used to provide for the amount of energy used to power up the appliances in the campus.

Ajinomoto Stadium or previously known as the Tokyo Stadium is a Multi-Purpose Stadium. Over the years, an improvement has been made whereby engineers have installed skylight BIPVs that are not only a source of providing electricity but also acts as a shelter.
Having skylight BIPVs allows sunlight to go through and at the same time harvest the energy at the use of it’s advantages. Compared to the old roof, the stadium stands looked slightly darker than now when they change the roof to skylight rooftop.

The first ever BIPV building was built in Japan. The type of BIPV used on the building are sunshade BIPVs, where they allow sunlight to pass through and also control the heating & cooling load.
Besides that, the orientation of the BIPV, is that it follow the Sun’s Orientation. As you can see, the BIPV is tilted at a certain degree and it’s not parallel to the window. The BIPV technology they’re using is transparent monocrystalline
From there, they could harvest as much energy as they can & their maximum power capacity they could harvest out of this BIPV is 20kWp.

In Korea, the Federation of Korean Industries have created a building with a curtain wall of BIPVs. The Building Owner have decided to use BIPV. To incorporate BIPV to it’s building, first they must determine the optimal areas through a model called Ecotech. After reviewing on each façade of the building, South, East & West, it came to a conclusion where they will install the BIPV on the West Façade as it receives the most direct radiation & sunlight. Besides, they also install it on the roofs. The BIPV system was based on the layout that would maximize the number of 5×5 monocrystalline silicon cells. And the total number of BIPV panels were used is 1,130 with 211883 5×5 Monocrystalline silicons cells. The Total Energy they harvested from the direct sunlight is about 844028kWh.

In Jiangxi province of China has been equipped with BIPV modules from the company, Hanergy. Hanergy has applied 6000m² of its BIPV product, called HanWall Oerlikon modules on the building façade. Claiming that this is the biggest photovoltaic glass curtain wall in China.
Using BIPV, the building is able to generate electricity as well as reduce solar radiation for the indoor space leading to cooling of the temperature inside the building. The electricity generated by the modules will majorly used to power indoor lighting, ventilation system and air-conditioning to reduce the building’s dependence for electricity on national grid.
