Solar Mounting Systems – What is it?

Every photovoltaic project has to have construction to install solar panels. Except for BPV where construction systems are integrated with buildings, solar modules need to install somehow. The solar mounting system can be different in case of many factors like:

  1. Place where PV Module will be mount 
  2. Project specification
  3. Tracking systems or standard system
  4. Movable or Stationary
  5. For specific modules like bifacial or BIPV e.g. facade systems
  6. Material from which mounting system is made e.g. aluminum or steel

To check each photovoltaic mounting system’s characteristics and answer the question of what system is for specific needs, AKCOME Metals Company will be analyzed.

Ground Mount Solar Racks.

For big PV investment and utility-scale solar projects mostly is used Ground mounting systems. Probably it’s the most efficient system for making solar installations. This solar solution is :

  • flexible and it can be created on many different configurations 
  • mostly easy to make if it standard solar project
  • most effective with bifacial modules like HJT N-type
  • When solar panels are on tracker construction, achieved maximum power 

Most of the ground systems are used for centralized PV power plants, which are mostly on large scale (up to hundreds of MWs) and installed in harsh environments (used in mountains, deserts, etc.). The corresponding ground system is economical, safe and stable with strong environmental resistance and multi-terrain adaptation which are particularly important. Akcome Metals has developed a variety of materials, structures and foundations to perfectly respond to the different application needs of customers.

Shed System, Carports and other specialist ground mount solar systems.

A shed-structure system is a more flexible and convenient photovoltaic power generation system that can be installed on the original shed or can directly replace the original building materials (saving construction costs) during new shed construction. This kind of solution can also be used for power generation and energy can be used for greenhouse lighting, charging and integration into the grid with economic benefits.

1. The most common structure for Agriculture is a greenhouse. It has a stable structure, high intensity and light transmittance of over 90%. Various activities can be carried out around the agricultural greenhouse, such as:

  • agricultural education,
  • agricultural research,
  • agricultural excursions,
  • etc.

The agricultural greenhouse offers city dwellers the opportunity to be close to nature and relax, experiencing a beautiful place outside the city.

Features of Greenhouse photovoltaic:

  • High power output.
  • You can freely adjust the light transmission.
  • You can meet the lighting needs of an agricultural greenhouse for different plants by modulating the density between the modules and the lighting glass.
  • Save water
    You can save water thanks to the built-in drainage system.
  • Automatic control of the agricultural greenhouse
  • The panel’s power generation automatically supplies light and water and regulates the temperature.

Intelligent Solar System Tracking, what is it?

The angle of the sun’s rays has a great influence on the energy capacity of a power plant. Tracking Stem helps you get the best sun angle by tracking the sun to maximize energy production. (Different dimensions can help increase from 10% to 20%).
Such technology is widely available, especially for new projects in the US and European countries.

The solar tracking system is widely used in solar panels and it is a device that directs the HJT modules towards the sun. The payload on trackers can be not only photovoltaic panels but as well reflectors, lenses or other optical devices. The sun tracking system is used to increase the overall power harvesting efficiency.

Features of solar tracking Systems? 

Safe and stable Simplified drive system: The whole array adopts rotary reducer drive to the control system, with low failure rate, and maintenance is easy.

High-quality slewing drive system: Stable self-locking mechanism can effectively protect the safety of the equipment.

The maximum single die installation power can reach 144KW with high drive torque and excellent environmental adaptation.

Design and stability testing: Bolt locking is used to avoid module slide problems that may be caused by insecure bolts. The tracking systems have undergone rigorous structural calculations to ensure product strength and stability.

Convenient and flexible Greater adaptability: can be flexibly used in projects such as ground systems, roof systems, agriculture, and fisheries linked systems.

Product assembly without welding: fewer categories of fasteners (less than 8 types).

Shorter installation time without the need for large equipment and Easy structure and convenient setup.

Intelligent and efficient functions for remote monitoring, maintenance and remote diagnostics.

Intelligent protection: intelligent control, which can realize bad weather identification automatic protection.

Multiple Operation Modes:

  • Rollback:
  • Remote Boot;
  • Pause;
  • Restoration;
  • Wind and snow resistance.
 

Types of solar tracking Systems? 

The solar tracking system includes types like a:

  • single-axis tracker, 
  • single-axis solar tilt tracker,
  • a fixed solar tracker,
  • and a dual-axis solar tracker.

 

Linear Single Axis Solar Tracker:
This kind of tracker can track the sun in an east-west direction and can only track the azimuth of the sun.

The sun tracking system should include a mounting bracket for solar panels(especially for Bifacial, Glass-glass HJT), a horizontal shaft, a rotary drive mechanism, a wind speed sensing device, and a tracking controller.

Features and Application Single Axis Solar Tracker:
The single-axis tracker is characterized by simple structure and low cost. Suitable for lower latitudes with large angles to the height of the sun. Its energy generation efficiency is 30% higher than solar panel constant tracking. The solar tracking system can be installed at ground or roof level.


2. Dual Axis Solar Tracker:
A two-axis solar tracker consists of a vertical shaft facing south and north, and several horizontal shafts mounted on a vertical shaft. Each little square of the solar module can rotate vertically around a vertical shaft and horizontally around a horizontal shaft. The sun tracking system consists of a horizontal shaft, vertical shaft, east-west putter, sun height angle putter, connecting rod, bracket, module bracket, sun tracking probe, wind speed probe and controller.
