Solarsolar panel installation - ADNLITE

With the increasing development of photovoltaics, how to choose suitable photovoltaic brackets according to local conditions is an important link to ensure the safe and efficient operation of the entire solar power system. Starting from the installation form, the existing Solar panel bracket can be roughly divided into two categories: Bracket on the ground; Bracket on the roof. Now ADNLITE will start from different application scenarios to introduce how to choose the photovoltaic support suitable for the project site.

Precautions during the design, material selection, and construction of Solar Panel Bracket

1 The installation structure of the solar panel bracket should be simple, strong, and durable. The material of the photovoltaic array bracket must be able to withstand various harsh environments on the project site to ensure 25 years of weather resistance, corrosion resistance, and structural strength. Electroplated aluminum profiles, electroplated steel, and stainless steel are all ideal choices. Meanwhile, the welding of the bracket must meet the requirements of the national standard “Code for Acceptance of Construction Quality of Steel Structure Engineering” (GB50205-2001). The weight of the array bracket should be reduced as much as possible when it meets the design requirements, so as to facilitate transportation and installation.

2 During the construction of the photovoltaic array foundation and support, it is necessary to avoid damage to related buildings and ancillary facilities as much as possible. If local damage is unavoidable due to construction needs, it should be repaired in time after the completion of the construction.

3 When installing photovoltaic arrays on the roof, the embedded parts of the base should be firmly welded or connected to the main structure of the roof. If welding or connection is not possible due to structural restrictions, measures should be taken to increase the adhesion between the base and the roof. And use the wire tensioning method or bracket extension fixing method to fix. After the foundation is made, the damaged roof or the involved parts should be waterproofed in accordance with the requirements of the national standard “Roofing Engineering Quality Acceptance Specification” (GB50207-2002) to prevent water seepage and rain leakage.

4 The frame and support of the photovoltaic cell module should be reliably connected to the grounding system.

Fixed form of ground installation of solar power system

1: Hammer into the ground

Measure the distance at the installation site, and drive the column into the ground directly by using the pile driver, which is convenient and quick. Before installation, geological and soil testing is required to determine the appropriate penetration depth.

The following types of profiles are suitable for hammer-in-ground piles, which can be selected according to actual conditions:

Hammer into the ground




Fast and adaptable;


Not restricted by seasonal temperature;

It is convenient to remove the piles and does not affect the reuse of the installation site.

2: Spiral pile

When it is inconvenient to hammer the column directly into the ground because the installation site is too hard or there are too many crushed stones, spiral piles can be used. Drive the screw-in steel pipe into the ground, and then fix the column on it.

Adaptable, Flexible;

Not restricted by seasonal temperature;

It is convenient to remove the piles and does not affect the reuse of the installation site.

3: Precast cement foundation

If the installation site is not suitable for plug-in piles, you can choose to make a cement foundation. The brackets are placed on the cement foundation and fixed with bolts.

Precast cement foundation










High strength and high precision;

Strong adaptability to the ground.

4:Direct cement pouring

Another form of cement foundation is to pour the bracket and cement together directly. Compared with the above, this method saves the time for bolting and fixing,but requires higher positioning accuracy of the support column during pouring.

Dual-axis tracking Bracket

According to the control mode, the dual-axis tracking system can be divided into time control type and light control type.

According to the geographical location and local time, the incident angle of sunlight is calculated in real-time, and the photovoltaic module is adjusted to the specified angle through the control system, which is also called astronomical control mode or clock control mode.

The incident angle of sunlight is measured by the sensing device, so as to control the rotation of the photovoltaic module and track the incident angle of sunlight, also known as the light-sensing control method.

Color steel tile roof solar panel installation system

Color steel plate roofs are usually installed in non-penetrating ways such as buckles, concealed buckles, and overlocking. In special cases, they can be installed through penetration.

First understand what a color steel roof is: steel formed by cold pressing or cold rolling of a thin steel plate. The steel plate adopts organic coating thin steel plate (or color steel plate), galvanized thin steel plate, anti-corrosion thin steel plate (including asbestos asphalt layer),or other thin steel plates.

Installation Precautions

1:First, repair the roof with wooden or bamboo board construction plank roads to prevent the material from being directly stepped on the roof slab during the secondary transportation, which will cause the roof slab to be deformed, and the sealant will come off and leak water.

2:Identify the position of the original structure roof purlin, and mark the specific position with the elastic ink line. the connection between the bracket and the color steel plate must be at the roof purlin position.

3: When walking on the roof, the construction personnel must wear insulated soft-soled shoes and walk through the troughs. The sundries on the roof slab must be removed every day to prevent rust and scratches on the roof slab.

4: there must be no omissions in all locations where sealing paste needs to be applied. After installing the outer roof panel, remove all the debris and iron filings on the roof. If the roof panel coating is found to be scratched, it must be repaired with a color board special repair paint. If the rivets and self-tapping screws are empty, they should be repaired with rivets and sealing paste at any time, and the rubber gaskets should not be damaged.
