The energy saving price of photovoltaic curtain wall

Purchase, installation, and O&M costs of the PV curtain wall systems (1 CNY = 0.1387 USD). The benefits of the systems derive from power generation and electricity savings for the air-conditioning system.

To address overheating and save energy in air conditioning, this study proposed novel single- and dual-inlet ventilation PV curtain wall systems (SVPV and DVPV). In summer, the building exhaust is introduced into the channel to strengthen PV cooling, while incoming fresh air is used to preheat dew-point air.

As an effective means of energy conservation and emission reduction, PV curtain wall technology has been extensively promoted since it is not only significant from the perspective of electrical gain but also allows for the collection and reuse of the generated heat in conjunction with air-conditioning systems.

Gas with harmful effect and no noise is a kind of net energy and has good compatibility with the environment. However, due to the high price, photovoltaic curtain walls are now mostly used for the roofs and exterior walls of landmark buildings, which fully reflects the architectural features.

Compared with ordinary curtain walls, PV curtain walls can not only provide clean electricity, but also have the functions of flame retardant, heat insulation, noise reduction and light pollution reduction, making it the better wall material for glass commercial buildings.

The PV curtain wall is the most typical one in the integrated application of PV building. It combines PV power generation technology with curtain wall technology, which uses special resin materials to insert solar cells between glass materials and convert solar energy into electricity through the panels for use by enterprises.
