(1) The roof should have enough sunlight
In my country, the roof where the photovoltaic power generation system is installed should face south as much as possible. We are in the northern hemisphere. When the photovoltaic tiles face south, the solar radiation is better and the power generation is also high. In addition, the roof should be prevented from being blocked by obstacles such as trees, mountains and tall buildings to ensure that the amount of light shining on the solar panels is sufficient.
(2) The roof should have enough utilization area
In fact, the power output of the photovoltaic power generation system depends to a large extent on the area of the solar panels you install. The usable area directly determines the installed capacity of the photovoltaic system.
(3) Identify the roof type
Identify the roof type, whether it is a flat roof or a pitched roof, or a metal roof, or the composition of the roof, whether it is concrete, ceramic tiles, terracotta tiles or a whole exposed material. Different types of roofs have different installation methods for photovoltaic tiles.
(4) Pay attention to waterproofing
If the building does not have a good waterproofing system, the roof may not meet the use function within its life cycle, which will affect the service life of the photovoltaic tiles.
(5) Pay attention to load-bearing capacity
The photovoltaic system must be built on the roof. If the roof's bearing capacity cannot meet the photovoltaic construction, the project will not be established.
(6) Pay attention to fire prevention, lightning protection and subsequent maintenance
The safety of the photovoltaic system itself and the building safety, including fire prevention and lightning protection maintenance channels; pay attention to effective protection of all contact points, lightning protection must be integrated with building lightning protection, and pay attention to reserving maintenance channels to ensure the safety of subsequent maintenance.
