Solar photovoltaic building is a new concept of applying solar power generation. It is a perfect combination of solar photovoltaic system and modern architecture. The photovoltaic modules are laid on the outer surface of the building structure to provide electricity, and the solar power generation system is integrated with buildings such as roofs, skylights, and curtain walls. , building green and environmentally friendly housing.
Photoelectric curtain wall, that is, pasted on glass, inlaid between two pieces of glass, can convert light energy into electricity through batteries. This is — solar photovoltaic curtain wall. It uses photovoltaic cells and photovoltaic panel technology to convert sunlight into electrical energy, and its key technology is solar photovoltaic cell technology. Solar photovoltaic cells use the photon energy of sunlight to move the electrons of the irradiated electrolyte or semiconductor material to generate a voltage, which is called the photoelectric effect.
In addition to the performance of ordinary curtain wall, the biggest feature of photoelectric curtain wall is the function of converting light energy into electrical energy. Solar cells use the photon energy of sunlight to move electrons in the irradiated electrolyte or semiconductor material to generate a voltage.
Advantage:
It requires no fuel, no waste gas, no waste heat, no waste residue, no noise pollution, and can be used to generate electricity. Because it can generate electricity, it can pay less electricity bills, and it can also sell excess electricity to the Electricity Bureau in foreign countries. It can be seen that the photoelectric curtain wall itself is a benefit. After adding photoelectric formwork to the photoelectric curtain wall, traditional building materials can be saved, for example, the photoelectric formwork can replace the polished natural building materials. The photovoltaic curtain wall also greatly reduces the burden on the environment, as it protects natural resources from loss.
In traditional power plants, it is most common to use fossil fuels to generate electricity, while using photovoltaic templates to generate 100 kWh can save 26 liters of fuel or 50 kilograms of coal, which also means that 57 kilograms of carbon dioxide and 71 grams of carbon dioxide are emitted. Sulfur dioxide and 75 grams of nitrogen oxides.
Feature:
1. Energy saving – Since the photoelectric curtain wall is used as the outer protection system of the building and directly absorbs solar energy, it avoids the excessive temperature of the wall and the roof, which can effectively reduce the temperature rise of the wall and roof, reduce the air conditioning load, and reduce the energy consumption of air conditioning .
2. Protect the environment – the photovoltaic curtain wall generates electricity through solar energy, it does not need fuel, does not generate waste gas, has no waste heat, has no waste residue, and has no noise pollution.
3. New and practical – relieve the power demand during the peak period of electricity consumption during the day, and solve the power supply situation in areas with power shortages and areas without electricity and low electricity. It can generate electricity and use it in place, reducing the cost and energy consumption of the current transportation process; at the same time, it avoids the additional occupation of precious building space for placing photovoltaic array panels, and integrates with the building structure, eliminating the need for a separate support structure for photovoltaic equipment. , but also between expensive exterior decoration materials, reducing the overall cost of the building.
4. Special effects – The photoelectric curtain wall itself has a strong decorative effect. Various photovoltaic modules are used in the middle of the glass, and the colors are various, which makes the building have rich artistic expression. At the same time, the back of the photoelectric template can also be lined with the designer’s favorite color to adapt to different architectural styles.
