The ultimate guide to the types of roofs suitable for installing household photovoltaic systems!
What kind of roof is suitable for installing photovoltaic panels?
In China, the roofs of buildings are classified based on their appearance into two types: flat roofs and pitched roofs.
Each type has its own advantages in terms of photovoltaic installation conditions.
The pitched roof has a large slope, which ensures smooth drainage during rainfalls.
Moreover, its construction is simple and it is easy to maintain. Installing a photovoltaic power station on a pitched roof does not require the installation of supports; instead, the photovoltaic panels are laid according to the inclination angle of the roof.
Since there is no need to consider the shading between the components, the components can completely cover the roof and are very aesthetically pleasing.
In China, pitched roofs are generally divided into single-pitched and double-pitched types. TCL Photovoltaic Technology has developed two household photovoltaic solutions, namely "Minghui Dian" and "Shuanghui Dian".
Among them, "Minghui Dian" has strong power generation capacity and combines aesthetics with benefits; "Shuanghui Dian" can fully utilize the characteristics of double-pitched roofs and does not depend on the orientation of the roof, allowing users to enjoy double power generation benefits.
In addition, if users want to use their own courtyard for photovoltaic power generation, they can adopt the "Huxue Yu" solution.
The photovoltaic power station in the courtyard can be used as a car shelter, and chickens and vegetables can be raised under the photovoltaic panels, and one can receive "pension" while enjoying the sunshine.
The special solution in the courtyard house - "Garden Truss House" is suitable for users who pursue maximum power generation benefits.
In this solution, the photovoltaic panels cover the entire roof from the top to the courtyard, which not only increases the area of the photovoltaic components to improve power generation efficiency, but also provides shade for the courtyard and does not occupy the activity space of the courtyard.
It can be said to achieve three benefits at once.
To fully leverage the aesthetic advantages of pitched roof photovoltaic power stations, TCL Photovoltaic Technology has created the "Zero Carbon Villa" solution.
Professional designers are responsible for the design of the power station, allowing the blue photovoltaic panels to perfectly blend with the roof, presenting a technological aesthetic with care. At the same time, "Zero Carbon Villa" is equipped with an energy storage system and charging piles, ensuring that the villa is self-sufficient in electricity, ensuring worry-free charging for the car, and creating a green, low-carbon, and intelligent high-quality life for villa owners.
Flat roofs usually adopt the form of cement blocks + photovoltaic supports.
The investment cost is not high, and the economic performance is relatively good.
On flat roofs, the photovoltaic array can be installed at the optimal angle to maximize the power generation efficiency.
Another advantage of installing a photovoltaic power station on a flat roof is that it can provide insulation and cooling for the house.
The engineers of TCL Photovoltaic Technology once tested the cooling effect of photovoltaic roofs in Haikou, Hainan Province.
The results showed that at 15 o'clock, the hottest time of the day, the temperature of the roof with the installed photovoltaic power station was on average about 6 degrees lower than that of the empty roof without installation.
