Most forecasts show that global solar energy usage will double in the next few years, with the rapid development of solar energy industries in South America and Asia. Solar energy is a wise business choice, because with the development of society, renewable energy will bring cost efficiency and at the same time benefit the environment.

Sino Green is a professional solar mounting system manufacturers. It can plan and design according to the different individual needs of customers, and tailor-made solar power generation systems with reasonable configuration, excellent cost performance, and various powers.Through continuous technological innovation and optimization of system solutions, we will continue to enhance the competitiveness of the industry, so that inexhaustible, inexhaustible, and ubiquitous green new energy such as solar and wind energy will enter thousands of households and create a better for mankind. To contribute to the future, as Chinese solar manufacturers go all out to expand production capacity as soon as possible.

There are many benefits of solar photovoltaic power generation:

1. Photovoltaic power generation is very suitable for rural areas with idle roofs. Those who have self-built houses can use the roof for investment and gain income.

2. Solar power generation is safe and reliable, and solar energy is an inexhaustible clean energy source.

3. Solar energy is a very ideal clean energy. Solar power generation does not produce any waste, and it does not produce the greenhouse effect, noise and toxic gases.

4. The production of solar energy greatly reduces operating costs because it does not require fuel.

5. Solar power generation is relatively easy to install, easy to maintain, and generally not easy to be damaged because it has no moving parts.

It can be seen that there are many advantages of solar power generation, which not only saves operating costs, but also facilitates installation and maintenance, and has a long service life.

There are four common methods for installing solar cell arrays on the roof:

bracket installation;

independent installation;

ƒ direct installation;

integrated installation.

Bracket installation

In the bracket installation method, the battery assembly is supported by a metal frame and presents a preset inclination angle. For the square array installed with brackets, the brackets are fixed on the roof with screws. This installation method will cause problems such as increased roof load-bearing and wind stress. However, since the air flow path completely surrounds the battery assembly, the assembly can maintain a relatively low operating temperature, thereby improving efficiency. Some bracket installation methods can adjust the inclination angle according to the season to improve the efficiency of the photovoltaic system.

Independent installation

Independently install the battery modules on the frame on the roof, which is parallel to the inclination of the roof.

Angle, and 10 ~ 20cm high from the roof. The supporting crossbars are fixed on independent frames, and the components are fixed on these crossbars. The independent installation method provides a free flow path for the square array. The disadvantage of the independent installation method is that it is difficult to maintain the square array and replace the roofing material.

Direct installation

The direct installation method installs the battery modules directly on the cover of the ordinary roof, so there is no need for supporting frames and cross bars. The components must maintain the integrity of the roof covering seal, so the roof must be sealed with a suitable sealant frequently.

The air flow of the direct installation system cannot flow around the square array components, which results in the component working temperature in this installation method being approximately 20°C higher than other installation methods. Since the electrical connection of the square array cannot be fully observed, this brings difficulties to analysis, repair and maintenance.

Integrated installation

The integrated installation method installs the battery modules directly on the roof rafters, and replaces the conventional roof covering with the battery modules. The square array is sealed with glazed butyl synthetic rubber or gasket material equipped with metal slats. This installation method is suitable for occasions where the roof orientation and inclination are suitable for sunlight. This kind of system is easy to ventilate, so it can ensure that the battery phalanx runs at an efficient operating temperature. Because the connection lines of the solar panels are exposed in the attic, it is easy to check and repair the lines.

The photovoltaic glass curtain wall is also an integrated installation method. In this way, the solar cell is sandwiched between two layers of ultra-white glass. Solving the heat dissipation problem of the solar cell is the key technology used in this way.
