(1) Installed on the idle roof or wall, without rated land or additional equipment, suitable for densely populated local applications.

(2) Photovoltaic solar panels can generate electricity in place, use electricity in place, within a certain distance can save the power station to the power grid investment, for the networked household system, the power generated by the photovoltaic array can supply the construction load, but also into the grid, in the summer to alleviate peak power demand.

(3) Because the photovoltaic array is installed on the outer envelope structure such as the roof and wall, it absorbs solar energy and converts it into electricity, greatly reducing the outdoor induction temperature, reducing the wall heat and indoor air conditioning cooling load, which not only saves energy, but also helps to ensure indoor air quality.

Avoid solar panel air pollution and waste pollution caused by the use of general fossil fuel power generation, which is more important for today and the future with strict environmental requirements.

Because of the componentization of photovoltaic cells, photovoltaic arrays are very simple to install, and can be arbitrarily selected power generation capacity.

The green electricity generated by thin film solar cell skills is provided to the internal use of the building, which plays the role of heat insulation to greatly improve the internal comfort of the building, so that the construction of energy saving and consumption reduction and photovoltaic power generation have reached the ideal situation of useful complementarity. BIPV modules can use the solar power irradiated on the surface of the building to reduce the indoor solar radiation by 60%. The double silver glass in the lighting area can reduce the heat transfer coefficient by 21% in the high light transmittance, in summary, the average decrease of room temperature 5-8 degrees Celsius, reducing the north-south temperature difference, warm in winter and cool in summer, heat preservation and insulation, because of the change in room temperature, the power consumption of air conditioning is estimated to decrease by 15%.
