(1)Solar panel bracket mounting form
The solar panel bracket mounting form is fixed to the outer wall and the roof of the building by two angled plated steel solar panel mounting brackets, and the other pair of brackets are attached to the end of the solar battery module frame. When connected, it constitutes a simple, durable and inexpensive bracket device for mounting a solar array. The cradle device can be made rotatable to adjust the solar cell tilde angle as the season changes, thereby optimizing the performance of the photovoltaic system.
(2) Column installation form
The column installation form uses a vertical column directly fixed to the ground to install a solar cell array. Generally, a 5 to 7 cm diameter steel pipe is suitable as a material for such a solar panel mounting support structure. With this installation method, the solar cell matrix tilt angle can also be adjusted seasonally to optimize the performance of the photovoltaic power generation system.
(3) Ground installation form
When installing a solar cell array on the ground, the pedestal should be pre-made on the ground, then the metal frame should be fixed on the pedestal, and finally the solar cell array should be mounted on the frame. The mounting frame usually consists of two parallel grooved beams. The laterally supported aluminum profiles are fixed on the grooved beams with screws. The strength of the laterally supported aluminum profiles is high to prevent the wind from being blown, and then the solar cells are square. The aluminum frame is screwed to the upper and lower lateral solar panel support aluminum profiles (should be fixed at pre-measured inclination). It is also possible to purchase or make a bracket device with an adjustable tilt angle to adjust the solar cell matrix tilt angle seasonally.
Since the lime component of the concrete corrodes the aluminum material, the metal frame directly mounted on the concrete base should be galvanized steel. In addition, screws, nuts and washers should be made of stainless steel to prevent corrosion. Before selecting the solar cell array installation location, detailed assessment of the local climate and soil pressure capacity should be performed. Ground mounting requires a base of sufficient strength to avoid damage due to excessive pressure. The pedestal must also withstand the tangential (lateral movement) forces caused by the wind. Reference to local building standards can provide a basis for determining pedestal requirements, and prior to installation, ensure that the support members meet these criteria.
(4) Roof installation form
The solar cell array is the connection of multiple photovoltaic modules and is also the connection of more solar cells. There are two types of solar cell arrays combined with buildings: roof mounting and side façade mounting. These two installations can cover the solar cell array installation of most buildings. The main form of PV array roof installation is:
1) Horizontal roof. On a horizontal roof, the solar cell array can be installed at the optimum angle to achieve maximum power generation. The conventional crystalline silicon photovoltaic module can be used to reduce the component investment cost, and the economy is relatively good, but the appearance is general.
2) Tilt the roof solar panel mounting. In the northern hemisphere, roofs that are inclined to the south, southeast, southwest, east, or west can be used to install solar arrays. 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 crystalline silicon photovoltaic modules can be used, which have good performance, low cost and good economy. It has no conflict with the function of the building, and can be closely combined with the roof and has a good appearance.
3) Photovoltaic lighting roof. The transparent photovoltaic cell is used as the building component of the lighting roof, which has good aesthetics and meets the needs of light transmission. The roofing components must meet certain architectural requirements such as mechanics, aesthetics, structural connections, and require transparent photovoltaic modules (transparent components are less efficient and costly), resulting in high power generation costs. But it can enhance the social value of the building and bring the effect of a green concept.
