Six common precautions for the use of photovoltaic modules solar panels

2023-01-04

1, solar cell modules can not be installed in trees, buildings and other shading places, can not be close to the fire or flammable near. The assembly structure should be able to adapt to environmental requirements, select suitable materials and anti-corrosion treatment, to use a strong and reliable method to install components, components or fall from a height, will cause financial damage. The components shall not be disassembled, bent or hit with hard objects to avoid dangerous actions such as stepping on the components. 2. Use spring washers and flat washers to fix and lock the solar panel components on the bracket. The installation of the solar panel is best about 30 degrees to the sun. According to the site environment and the state of the assembly bracket structure, the solar panel components shall be wired in an appropriate manner. image.png 3. The solar panel assembly should correctly link the positive and negative poles in the junction box. The output circuit should be correctly linked to the equipment. The positive and negative poles should not be shorted. Ensure that there is no gap between the connector and the insulating connector. If there is a gap, sparks or electric shocks will occur. 4. Always check whether the hoisting structure falls off. If necessary, tighten the parts and check the link status of each part, each wire, bottom line and plug. image.png 5, often use soft cloth to check the surface of the test component. If you do replace (generally 25 years do not need to replace) solar panel components, should choose the same type of components, can not touch the part of the cable connector, if you really need to use safety equipment (such as insulating gloves, etc.). 6. Please cover the surface of the component with opaque objects or materials when overhauling the component, because the component will generate high pressure under strong light, which is very dangerous. The warranty period of the components is 3 years, and the power attenuation of the components will not exceed 10% within 10 years, and will not exceed 20% within 20 years.

What is the function of solar power system

2023-01-04

1. Solar panels: Solar panels are an important part of the mobile phone software of the solar power system, and they are also part of the practical value of the mobile phone software of the solar power system. Its function is to convert the professional ability of radioactive materials in natural light into electrical energy, or send it to the battery for storage, or to promote the work of the load. 2. Solar controller: The function of the solar controller is to control the operation of the mobile phone software in all systems, and to protect the battery from overcharge and overcharge maintenance. In areas with large temperature differences, a qualified controller should also have the function of temperature compensation. In the mobile phone software of the solar road street light system, there must be a light-controlled switch and a time-controlled solar street light operation. 3. Battery: generally valve-controlled maintenance-free lead-acid batteries. In the mobile phone software of small and medium-sized systems, in cold weather areas, it is necessary to configure a solar gel battery, which can be used at low temperatures, has high efficiency and is not easy to be damaged. Its function is to store the electric energy of the solar panel when the sun is shining, and then release it under certain circumstances. 4. Variable frequency power supply: split wave type and sine wave type. In order to provide electric energy for 220VAC electrical products, it is necessary to convert the DC regulated power supply in the solar power system software into AC circuit energy, so it is necessary to use DC AC variable frequency power supply.

Seven advantages of industrial roof photovoltaic power generation

2023-01-04

For most industrial and commercial owners, installing photovoltaic power stations on the roof of factories or enterprises can not only reduce the energy consumption of enterprises, but also make full use of idle resources, play the role of energy conservation and emission reduction, and bring economic benefits to enterprises. The seven advantages of industrial roof photovoltaic power generation 1. Use idle roof ground to revitalize fixed assets and increase corporate income and added value 2. Save peak electricity charges for enterprises (peak power generation during the day Z more), and the rest can be sold online 3. Reduce the internal temperature of the factory, improve work comfort, warm in winter and cool in summer 4. Take advantage of the advantages of the building, not limited by the resource distribution area, safe and reliable, no noise, no pollution 5. Adopt access to the near user side, without long-distance transportation, and avoid the loss of long-distance transmission lines 6. The solar power generation system has a short construction period and short time to obtain energy, which is convenient and flexible. It can add or reduce the solar energy array according to the load increase or decrease, and avoid waste 7. Good return on investment can run for at least 25 years. The ideal clean energy is fuel-free, low operating costs, and less prone to polluting waste during power generation.

Ride and play on Huandao Road, and you don't have to worry about no electricity or network anymore!

Division I obtained two standards

2018-01-16

The technical specifications for solar lawn lamp system and independent solar photovoltaic power supply system drafted and edited by our company have been evaluated by the State General Administration of Quality Supervision, Inspection and Quarantine and have obtained two national standards (standard numbers: GB/T 35264-2017,GB/T 33766-2017), which indicates that our solar lawn lamp system and independent solar photovoltaic power supply system are ahead of the same industry.

European Environmental Association experts praise solar yacht

2017-12-04

On December 6, 2017, experts from the European Environmental Protection Association were invited to Xiamen, China, to inspect the environmental protection and governance of Xiamen. Experts came to Yundang Lake and experienced the first domestic solar cruise ship jointly developed and produced by Xiamen Guanyu Technology Co., Ltd. and others. The experts all gave thumbs up and praised the solar cruise ship for energy saving, environmental protection, low-carbon, and technology. It has no oil pollution, no exhaust gas, and fully realizes zero carbon emissions. It is a truly green tour boat. Experts from the European Environmental Protection Association believe that it can be widely used in green business reception, green tourism and leisure in inland rivers, lakes, coastal and other water systems. It is understood that the European Environmental Protection Association, headquartered in London, is the earliest and most influential environmental law public welfare organization in Europe. The Association brings together lawyers and scientists to provide positive solutions to local, national and global environmental challenges. In 2015, the European Environmental Protection Association came to China to support the Chinese government to strengthen environmental governance, support the drafting and implementation of environmental laws and regulations, carry out environmental law enforcement training and knowledge exchange, and improve its law enforcement capabilities.
