What are the difference install ways for pv panels?

   The way pv panels are combined with buildings can be divided into two types: pv panels roof installation and pv panels side elevation installation. It can be said that these two pv panels installation methods are suitable for most buildings.As professional solar products manufacturer,Mars explained to you both of them.

      PV panels roof installations mainly include horizontal roofs, sloping roofs and photovoltaic roofs.

     Horizontal roof: On the horizontal roof, the PV array can be installed at the optimal angle to obtain the maximum power generation; the conventional pv array can be used to reduce the investment cost and the economy is relatively good. However, the aesthetics of this type of installation are general.

   Tilted roof: In the northern hemisphere, roofs that are inclined to the south, southeast, southwest, east, or west can be used to mount pv array. On the sloping roof in the south direction, it can be installed at the best angle or near the optimal angle to obtain a larger power generation; conventional pv array can be used, which have good performance and low cost, and therefore have better economy. And it does not conflict with the function of the building, it can be closely combined with the roof, and the appearance is better. The power generation performance of other oriented (positive south) roofs is second.

      Photovoltaic lighting roof: refers to the building element with transparent photovoltaic cell as the lighting roof, which has good aesthetics and meets the needs of light transmission. However, the photovoltaic lighting roof requires transparent components, and the module efficiency is low. In addition to power generation and transparency, the lighting roof components must meet certain mechanical, aesthetic, structural connection and other architectural requirements, high component cost, high power generation cost, and social value for the building, bringing the effect of the green concept.

      The side façade installation form mainly refers to the way of installing pv array on the south wall of the building, on the east wall and west wall of the northern hemisphere. For multi- and high-rise buildings, the wall is the outermost surface with the contact area of sunlight, and the photovoltaic curtain wall is a more common application form. According to the design needs, it can be combined with transparent, translucent and ordinary transparent glass to create different building facades and indoor light and shadow effects. Double-layer photovoltaic curtain walls, point-supported photovoltaic curtain walls and unitary photovoltaic curtain walls are the more common forms of photovoltaic curtain wall installation. In addition to photovoltaic glass curtain walls, photovoltaic facades, photovoltaic awnings, etc. can also be installed on the facade of the building.
