The concept of BIPV was first proposed by American scholars in the late 1970s. It’s a design that photovoltaic system is integrated into the building, which can assume the functions of traditional buildings while generating photovoltaic power. On the other side, it can save more space in city.Photovoltaic building integration in urban use, has important value and significance.At present, the development of BIPV as a roof is not very long.

The advantages of BIPV

1.There is no need to equip with batteries, which not only saves investment, but also is not limited by the state of battery charge, and can make full use of the power emitted by the photovoltaic system.

2.energy conservation and emission reduction. Photovoltaic arrays absorb solar energy into electricity, greatly reducing the outdoor temperature, wall heat and indoor air conditioning cooling load, so it can also play a role in building energy saving.

3.More energy and less space. BIPV technology can produce more energy than traditional solar panels and require less space

The disadvantages of BIPV

1.High cost.

2.Longer return on investment.

3.The property of building materials is weak. Many commercially available BIPV products fail to meet the most basic building material requirements in terms of key attributes such as water resistance, fire resistance, wind resistance and heat dissipation.

With the continuous improvement of photovoltaic industry maturity, the economy of "photovoltaic + building" is also gradually improving.

With the gradual scarcity of ground power stations and high-quality large-scale roof resources, the huge market of photovoltaic building integration has begun to attract the attention of capitalists in the market, along with the further decline of photovoltaic costs.
