Governments around the world have implemented a variety of incentive policies to promote the development and application of solar energy and other renewable energy. Among them, solar energy is considered to be a promising energy source. Generally speaking, solar power generation systems are mainly divided into two types, one is centralized, such as large-scale northwest ground photovoltaic power generation system; the other is distributed, such as industrial and commercial enterprise factory roof pv power generation system.

The energy produced by the sun for every hour of exposure to the earth can meet the global energy demand throughout the year. Unlike traditional energy sources that require refining and burning fossil fuels and occupy an area that is time-consuming, anyone can purchase and install solar modules and enjoy abundant solar resources. In the long run, the use of solar energy can also save significant and long-term electricity costs.

1.Save electricity costs

The installation of solar energy systems can significantly reduce monthly electricity costs and dependence on the grid, and the energy independence brought about can protect users from rising electricity costs and rising fuel prices. According to analysis and forecast, the efficiency of photovoltaic power generation will continue to rise, which makes solar energy a high-yield solution and long-term investment in the future.

2.Increase house value

According to reliable data, houses with solar energy systems are sold at a rate of 20% faster than houses without installation, at a premium of 17%. Installing solar racking systems can make houses more attractive and have a higher resale value.

3.Reduce carbon footprint

Unlike traditional fossil energy, the use of solar energy will not emit harmful gases to the environment. As a sustainable carbon-free energy solution, solar energy is essential for slowing climate warming and avoiding further damage to the environment.

Roof mounts allow solar customers to mount solar panels to existing space on their roofs. They are suitable for structures that are relatively modern and can support the full weight of a solar system. Compared to ground mounts, they are simpler and less expensive to install and generally do not require additional structural support.

The flat-roof mounting system has widespread applications on both residential and commercial buildings.

The main difference for commercial applications is that the flat-roof mounting system is applied to large flat rooftops, like manufacturing plants or stores. Roofs in these buildings have a tilt but not as much as the slopes that we see on residential roofs.

Flat-roof systems are installed on a rather spacious and level surface. These systems are easy to install and have the benefit of pre-assembly.

Reasonable photovoltaic support foundation can improve the wind load resistance and snow load resistance of the solar pv mounting systems. Rational use of the characteristics of solar mounting structures, we can further optimize its dimension parameters, save materials, and make contributions to further reduce the cost of solar racking system.

The following is a comparative analysis of the advantages and disadvantages of different foundation.

1.Cement pier foundation support

Flat roof concrete foundation support is currently the most commonly used installation form in flat roof solar power stations. According to the form of foundation, it can be divided into strip foundation and independent foundation; the connection between the support column and the foundation can be connected by anchor bolts or directly embedded the columns into the concrete foundation. Advantages: Good wind resistance, no damage to roof.

Disadvantages: Long construction period.

2.Concrete ballast bracket

Ballasted solar mount systems are designed without penetration on rooftop or pouring of concretes. Specially suitable for residential concrete roof power station. It have been treated with high quality anti-corrosion treatment and is suitable for installation in harsh weather conditions with long service life.

Advantages: Easy installation and save construction time

Disadvantages: Wind resistance is relatively poor.

What's the function of solar pv mounting systems on the roof?

1.The photovoltaic system on the roof can "regulate" the indoor temperature. Beat the heat in summer and keep warm in winter.

2.Rooftop solar mounting systems, using sunlight to generate green electricity, really achieve the actual action of energy conservation and environmental protection.

3.Directly connected to the network on the client side, there is no need to increase the voltage, which saves a lot of cost and time.

4.The combination of solar mounting system and roof makes the reinforced concrete roof revitalized. At the same time, the original homogenized roof shows its personality, which is also an effective display of beauty and social responsibility. In addition, domestic photovoltaic power generation enjoys the national subsidy per kilowatt hour, and the national grid will recycle the unused electricity.

At present, the solar pv panel mounting systems widely used in the roof has two construction methods: one is that the inclined tile uses the track to tile the panels, and the other is that the horizontal roof uses the bracket to support the panels, both based on the roof's sun angle and lighting effect, so as to ensure the maximum efficiency of the panels' power generation.

Introduction of fixed solar mounting structure

Fixed solar mounting structure, which means photovoltaic array does not rotate with the change of solar incidence angle, but receives solar radiation in a fixed way. According to the setting of tilt angle, it can be divided into three types: fixed tilt solar mounting bracket, solar mounting system for pitched roof and adjustable tilt solar mount. Here we emphatically introduce the fixed tilt solar mounting bracket.

The fixed tilt solar mounting bracket, which the tilt angle is fixed, and the annual accumulated radiation is the largest. Firstly, the best installation angle is calculated, and then all best solar panels in china are fixed with this angle. It can be simply classified by three types.

1) Concrete foundation solar racking system: There are many kinds of solar pole mount. According to the geological conditions of different projects, the corresponding installation methods can be selected.

Ground screw solar mount structure: It can be divided into narrow leaf continuous ground screw pile and wide leaf interval ground screw post.

Rammed pile ground mounting solution: The pile is mainly driven into the ground by C type/H type steel or other steel. The installation is very easy.
