Speaking of the concept of "photovoltaics", many people are relatively unfamiliar. When it comes to solar energy, many people feel so close to our lives, such as common solar water heaters and solar carports. And what is the "home solar power", can my roof be installed?
What is "home solar power"?
The name implies that it is a small solar power generation system for home use, which is installed on an independent roof and is generally composed of solar cell modules, inverters, brackets, and other parts. Solar energy is converted into direct current through photovoltaic modules and then converted into alternating current through inverters for home use. The birth of the "home solar power generation" system conforms to the trend of clean energy applications on the one hand; on the other hand, it conveniently solves the problem of household electricity use and has "clean and environmentally friendly, nearby use, spontaneous self-use, and surplus electricity on the Internet" And other advantages.
Which roofs can be installed "home solar power"
The installation of "home solar power" must be on an independent roof. For example, common residential houses and villas built by residents can be installed. Three types of roofs are very suitable.
Beveled roof
Sloped roofs are generally more beautiful. Due to the large slope of the roof, rainwater is easy to remove, and the construction is simple and easy to maintain. This type of roof is generally adopted in rainy areas.
Installing a solar power station on a sloping roof does not need to increase the support and calculate the inclination. The installation can be carried out according to the inclined angle of the roof itself. At the same time, the installation capacity is not affected by the area. Due to the large slope, it can also play the role of automatic cleaning of the power station. The biggest advantage of installing a solar power station on a sloping roof is that the building integration effect is obvious, that is, it is very close to the roof, it will not affect the aesthetics of the house, and it will also make the roof high-tech.
flat roof
The roof slope is less than 5% (2.86 degrees) is a flat roof, which saves time and effort, is simple and generous, can be used as an event venue, as a drying place, but the flat roof drainage is slow, and it is easy to produce leakage. General heat. The biggest advantage of installing a solar power station on a flat roof is its heat insulation and cooling. It must be known that installing a solar power station can reduce the temperature by 5 ~ 7 degrees, and the effect is very obvious.
For flat roofs, there are two main ways to install solar power stations:
（1) Steel frame shed
The so-called steel shed is to increase the support to install a solar power station, which is equivalent to covering the roof with another layer of a sunshade, which will not affect the roof space.
(2) Bracket installation
In the form of cement pier + photovoltaic support, in order to ensure the power generation, the optimal inclination angle must be determined according to the geographical location of different regions and the actual situation. space.
Sunroom roof
The sun room is also called a glass room. It is a completely non-traditional building built with glass and metal frames to achieve the purpose of enjoying the sun and getting close to nature. Adding a layer of solar power generation equipment on top of the sunroom not only reduces the direct exposure to ultraviolet rays but also provides its own daily electricity.
