How to install roof solar panel mounting bracket system?

Roof-mounted solar panels that you do not know the three stent types

 For residents of the installation of photovoltaic solar panels, the most common method of fixing components are embedded in the roof bracket system. The meaning of the name is that this stent system components to solar panels placed in parallel, very close to the roof surface. This stent obtained effect is very pleasing, and the wind loads, the effect of wind on the back and move the square building is minimized.

Despite the composition consists of the following part of the commercial supply of the embedded roof bracket system.
A whole system is fixed to the roof of the footing
Track support assembly 2
3 clamp assembly is secured to the track.
 
Tilt bracket
To keep manufacturing costs low, many manufacturers regard the stent embedded roof bracket system to the factory have inclined properties. This same bracket feet fixed to the roof, track assembly with the same support, but behind the assembly of aluminum parts has propped up, it has a slope of the roof, so that the square can be tilted to any desired angle. Many manufacturers of such products are equipped with telescopic legs can make the installer in a certain tilt angle range to make a choice.
 
Ballast stent
Because such buildings watertight willingness overwhelming, so many people, including photovoltaic building owners and enthusiasts, prefer to use ballast stent system, rather than holes in the roof and the tilt bracket system is fixed on it. Ballast stent use phalanx own weight and additional weight makes the positioning matrix, which are the same as in other aspects tilt stand.
 
In addition to the previously mentioned line spacing, before using ballast stent system, also need to consider the following points.
Weight increase above the roof 1: Because the roofs increased ballast weight bracket, must ask a structural engineer for structural assessment. This fee is usually paid by the user, and it will increase the time the front end of the design process.
2 square tilt is limited: because the weight of the system must suppress everything, so it is necessary to reduce the inclination of the square, to minimize the wind force elected, so that the system will not be blown away.
3 water may block: who need to easily flow to the design of the drainage system if the water channel is blocked, it is sometimes possible infiltration of water into the building to happen.
4 roof layout needs to avoid the peaks and valleys: If using ballast system, the stent will be in direct contact with the roof, so it can not cross any of the peaks and valleys (the roof is not really flat, so do it quite difficult), therefore, when the scene, taking into account all the characteristics of the roof, and they make an accurate record.
 
In addition, the metal roof panels can be installed Tianyang Note: Due to the life of the metal roof is very long, so lightweight, low maintenance requirements, particularly the seams unchanged metal roof is the first choice of many people in the roofing. When the metal roof installed solar energy panels days, must pay attention to:
1 sheet metal on the roof will shrink
2 metal sheet fixed to the roof of the method
