With the construction of new rural areas, more and more rural families have built new houses, which are not only related to their living standards, but also related to the concept of rural families. As long as some money is collected, most of them will choose to cover New house, no new house, new wife?
How can I make the house beautiful and tall? The roof is an important part. The common roof forms are mainly flat roofs, sloping roofs and flat roofs. What is the difference between installing photovoltaic power plants on these three roofs?
The slope of the roof is less than 5% (2.86 degrees). It is a flat roof. It saves time and effort, is simple and generous, and can be used as an activity site. As a drying place, the flat roof is slow to drain and is prone to leakage. At the same time, in the summer, the house is not General heat.
The biggest advantage of installing a photovoltaic power station on a flat roof is that it is insulated and cooled. It is necessary to know that when installing a photovoltaic power station, the temperature can be lowered by 5 to 7 degrees. The effect is very obvious. For flat roofs, there are two main ways to install PV power plants:
(1) Steel frame shed
The so-called steel frame shed is to increase the bracket to install the photovoltaic power station, which is equivalent to the roof and a layer of awning, which will not affect the activity space of the roof.
(2) Bracket mounting
In the form of cement pier + photovoltaic bracket, in order to ensure the power generation, the optimal inclination angle should be determined according to the geographical location of different regions and the actual situation. In order to ensure that the front row components do not block the rear row components, there must be a gap between the two rows of components. space.
Sloping roofThe slope roof is generally more beautiful. Due to the large slope of the roof, the rainwater is easy to remove, and the construction is simple and easy to maintain. In the rainy areas, this roof form is generally adopted.
The biggest advantage of installing a photovoltaic power station on a sloped roof is that the building integration effect is obvious, that is to say, it is very close to the roof, which does not affect the aesthetics of the house, and can make the roof become high-tech.
Installation of a photovoltaic power station on a sloped roof does not require an increase in the support and calculation of the inclination. The installation can be carried out according to the inclination angle of the roof itself, and the installation capacity is not affected by the area. For example, if the flat roof is installed 3KW, it needs 30 square meters, and the slope roof can be 20 square meters. Due to the large slope, it can also be used to automatically clean the power station.
Flat roofAs the name suggests, it combines the two forms of roofing, so it combines the advantages of both roofs to enrich the building's shape while simplifying the building's shape.
The characteristics of this kind of roof-mounted photovoltaic power station are basically similar to the first two, but the form is more flexible. It can be built on top of a flat roof for installation and insulation, or it can be laid on a sloped roof, depending on personal needs.
The installation of photovoltaic power station on the roof not only plays a role of heat insulation and cooling, but also creates beautiful green effects. It also protects the roof of the house and plays a green and environmental protection role. With the strong support of the country and the leap of the photovoltaic industry Development, photovoltaic power plants will also become standard, become a wealth management products well known to the public.
