According to the different installation methods of the combination of double glass solar panel and building, it can be divided into photovoltaic building integration and photovoltaic building addition.

①Installed on the roof or wall of an idle house, no additional land or additional equipment is required, and it is suitable for use in densely populated areas.

②Double glass solar panel can generate electricity in situ and consume electricity in situ. Within a certain distance, it can save the investment of the power station and power grid. Connected to the grid, it can alleviate peak power demand in summer.

③Because the photovoltaic array is installed on the outer protective structure such as the roof and the wall, it absorbs solar energy and converts it into electric energy, which greatly reduces the outdoor comprehensive temperature, reduces the heat gain of the wall and the cooling load of the indoor air conditioner, which not only saves energy, but also Helps ensure indoor air quality.

④ It avoids the air pollution and waste residue pollution of double glass solar panel panels caused by the use of general fossil fuels for power generation, which is more important for today and the future with strict environmental protection requirements.

⑤Because of the componentization of photovoltaic cells, the installation of photovoltaic arrays is very simple, and the power generation capacity can be selected arbitrarily.

The green power generated by thin-film double glass solar panel battery technology is used to provide internal use of the building, and at the same time it plays a role of heat insulation, which greatly improves the comfort inside the building, and makes the building energy saving and photovoltaic power generation achieve an ideal state of effective complementarity. BIPV modules can effectively use the solar power irradiated on the building surface to reduce indoor solar radiation by 60%. The double silver glass in the lighting area can reduce the heat transfer coefficient by 21% while having high light transmission. In summary, the average The room temperature is lowered by 5-8 degrees Celsius, the temperature difference between the north and the south is narrowed, the winter is warm and the summer is cool, and the heat preservation and heat insulation are used. Due to the change of the room temperature, the power consumption of the air conditioner is estimated to be reduced by 15%.
