Integration of Photovoltaic buildings

It is generally believed that pv can only be installed on the roof, but the combination of PV and building is one of the important fields of pv application in the future. Its development prospect is very broad, and it has huge market potential. Today guangxi photovoltaic power generation xiaobian and we talk about the integration of photovoltaic and architecture.

The integration of photovoltaic buildings has obvious advantages:

(1) The integration of solar photovoltaic buildings is a green energy generated by the application of solar power generation, which will not pollute the environment. The solar energy is relatively clean and free of charge, and the development and utilization process will not produce any ecological side effects. It is also a kind of renewable energy, inexhaustible.

(2) Photovoltaic array is generally installed on the idle roof or outer wall without taking up extra land, which is especially important for urban buildings with expensive land; Summer is the peak season of electricity consumption, which also coincides with the period of large sunshine volume and large photovoltaic system generating capacity, which can play a role in peaking the power grid.

(3) The integrated solar photovoltaic building technology adopts the grid-connected photovoltaic system, which does not need to be equipped with batteries. It not only saves investment, but is not limited by the charged state of batteries, and can make full use of the electricity generated by the photovoltaic system.

(4) Play the role of building energy conservation. Photovoltaic array absorbs solar energy and converts it into electric energy, which greatly reduces the outdoor comprehensive temperature, reduces the heat of the wall and the cooling load of indoor air conditioning, so it can also play a role in building energy conservation. Therefore, the development of integrated solar photovoltaic building can "save energy and reduce emission".

According to different ways of combining photovoltaic phalanx with buildings, the integration of solar photovoltaic buildings can be divided into two categories:

One is the combination of photovoltaic phalanx and architecture. In this way, the PHOTOVOLTAIC array is attached to the building, and the building plays a supporting role as the photovoltaic array carrier.

The second is the integration of photovoltaic phalanx and architecture. In this way, photovoltaic modules appear in the form of building materials, and photovoltaic phalanx becomes an integral part of the building.
