Photovoltaic people must know! 

Colour steel tile roof installation of industrial and commercial power station of the six processes

In the photovoltaic subsidy reduction, flat price online trend, industrial and commercial photovoltaic project, due to photovoltaic power generation and load power consumption relative synchronisation, self-generated high proportion of self-consumption, electricity prices are relatively high, investment returns and other advantages, become the meat and potatoes in everyone's eyes. So, which roofs are suitable for the installation of photovoltaic power plants?

Common, industrial and commercial photovoltaic project installation form mainly in three forms: colour steel tile roof tiling type, cement roof array type and cement roof scaffolding type; in the large-scale industrial and commercial photovoltaic project inside, most of the roof to the colour steel tile structure is mainly, therefore, the enterprise in the installation of photovoltaic power station, colour steel tile tiling type is very close to its own needs.

The main structure of colour steel tile also has several kinds: upright lock edge type, angle chi type, T type and snap type, etc. According to the relevant photovoltaic industry website statistics, at present on the market colour steel tile flat paved photovoltaic project installation most commonly used is the angle chi type structure, and wuhan kwa new energy of industrial and commercial colour steel tile flat paved photovoltaic project is mainly to the angle chi type structure to pave, and at the same time kwa suggests that industrial and commercial photovoltaic project to this structure to pave! We also suggest that industrial and commercial PV projects should be laid with this kind of structure, which is easy to install and safe.

We also according to have done the industrial and commercial colour steel tile paving photovoltaic case, summed up its installation advantages:

1, solid and sturdy, using special fixture fixed on the tile surface;

2、Easy to install, install the aluminium guide rail on the upper end of the fixture, lock it with bolts, and systematically check the installation position and torque of each component and bolt at regular intervals;

3、It has direct protection against light radiation and rain erosion problems, and improves the service life of colour steel tiles;

4, wind resistance and heat insulation, reduce the ambient temperature of the plant and enhance the strength of wind resistance;

5 colour steel tile idle roof use, safe and worry-free, long service life, power generation and increase income and light.

Then what are the processes when the photovoltaic project landed? Take China as an example:

1, site survey, according to customer demand to determine the programme

(1) before installation, the company arranged professional technical designers to the project site with the help of drones to survey, survey: the whole colour steel tile plant structure or steel frame structure, colour steel tile roof above whether there are sundries (such as the installation of the exhaust fan), shading shadows and observation of the colour steel tile belongs to which type of structure.

(2) technical designers and business personnel, project management to determine the design programme and specific design blueprints, into the field before reviewing the blueprints again, you can enter the field construction and installation. Different colour steel tile structure have corresponding type of fixture supporting installation. (Here show is upright lock edge type fixture, angle chi type fixture)

2、Project record of Development and Reform Commission

3、Project material preparation

5、Electricity formalities declaration, grid connection

4、Project materials into construction:

(1) Steel structure column point positioning

(2) Welding of steel structure frame

(3) Steel structure surface treatment (welding point grinding, fluorocarbon paint spraying)

(4) Structural waterproof bracket, drainage gutter and downpipe installation

(5) Module installation

(6) Installation of grid-connected inverter, grid-connected box, AC and DC lines

6、System operation and maintenance
