  • ITC policy promotes the rapid development of U.S. Solar Energy
    Apr 15, 2021

    In recent years, renewable energy in the United States has developed rapidly, and the ITC policy has played a large role. The Solar Investment Tax Credit (ITC) policy is one of the most important federal policy mechanisms to support the development of solar and other renewable energy in the United States. As part of US President Joe Biden's $2 trillion US infrastructure employment plan, ITC has again extended the validity period of 10 years this week. The Solar Energy Industry Association (SEIA) estimates that by 2030, extending the ITC policy will increase the share of solar energy in U.S. electricity by a third. Members who support this policy believe that the ITC policy can increase industrial and commercial photovoltaic and household photovoltaic, and reduce carbon emissions. This is an important part of green energy, which can increase employment opportunities, reduce dependence on foreign energy and improve the environment. Holly Christie, the general counsel of Hecate Energy, explained that there are two ways to deal with ITC policies. One is to start construction at the specified time, and the other is to buy 5% of the electricity. "The original intention of the tax credit policy is that the credit should depreciate over time. Therefore, if my project does not start this year, then as the industry starts, there will be a loss of a few percentage points." CORIGY SOLAR's solar mounting system is cost-effective.

  • Newest Trend Zinc-Aluminum-Magnesium (ZAM) Steel For Solar PV Mounting | Corigy Solar
    Dec 01, 2020

    The definition and historical origin of Aluminum-Magnesium-Zinc plating Definition: Aluminium-Magnesium-Zinc is a kind of alloy metal. It is mainly used for surface anti-corrosion treatment of steel and steel products.Initially pure Zinc is used for the surface anti-corrosion treatment of steel products. With the improvement of technology, alloy metals such as Aluminum-Zinc alloy and Aluminum-Magnesium-Zinc alloy have appeared one after another, which increases the corrosion resistance of the metal layer. Origin: It was originally developed and mass-produced by Japan's Nisshin Steel Corporation in the early 21st century. It is said that the purpose of development is to replace stainless steel in certain situation. Currently, it’s available in Jiuquan Iron and Steel, Tangshan Iron and Steel and Baosteel in China. With the industry upgrading, Aluminium-Magnesium-Zinc will be used more and more widely. Composition and classification of Aluminum-Magnesium-Zinc plating Aluminum-Magnesium-Zinc-coated steel sheet refers to a coated steel sheet in which a certain amount of Al and Mg is added to the existing hot-dip galvanized coating or a certain amount of Mg is added to the hot-dip Zinc-Aluminum coating. It has the characteristics of high corrosion resistance and high cutting edge protection performance. China Baowu Iron & Steel group has summarized and analyzed commercial Magnesium plating steel plates, and found that Magnesium content in most coatings is less than or equal to 3%. According to the difference of Aluminum content in the coatings, Aluminum-Magnesium-Zinc plating coatings can be divided into: 1. Low Al content Aluminum-Magnesium-Zinc coating. Aluminum content: 1-3.5%. The coating is formed by adding a certain amount of Al,Mg and other elements on the basis of hot-dip galvanizing. China Baowu Steel conducted its first industrial trial production in June 2016. The coated steel plate has also been tested by a color coating unit. And the color coated steel plate with low Al content Aluminum Magnesium Zinc substrate was developed successfully. The coating is an upgraded version of the corrosion resistance of the hot-dip pure Zinc coating. China Baowu Steel is referred to as BZM coated steel sheet and its color coated steel sheet. 2. Medium Al content Aluminum-Magnesium-Zinc coating, Aluminum content: 5~11% 3. High Al content Aluminum-Magnesium-Zinc coating, Aluminum content: 55%.The coating is formed by adding a certain amount of Mg and other elements on the basis of hot-dip Aluminum-Zinc. China Baowu Steel conducted its first industrial trial production in August 2016. The coated steel plate has also been tested by a color coating unit.

  • 10 Top Roof Solar Energy Questions to Ask- Get the Answers You Need
    Nov 03, 2020

    1. Will the panels reflect light and affect the neighbors? The photovoltaic modules are basically made of coated glass, with a transmittance of more than 93%. Most of the light sources will be absorbed, which will not cause light pollution and affect the neighbors. 2. Will the modules get electric shock after thunder? No, the photovoltaic system has lightning protection and grounding measures. 3. Is it necessary to disconnect the photovoltaic power generation system in thunderstorm weather? Distributed photovoltaic power systems are equipped with lightning protection devices, so it is not necessary to disconnect them. For the sake of safety, it is suggested to disconnect the circuit breaker switch of the combiner box and cut off the circuit connection with the photovoltaic module, so as to avoid the direct lightning stroke which cannot be removed by the lightning protection module. 4. Will the panel generate radiation? Photovoltaic power generation system is based on the principle of photovoltaic effect to convert solar energy into electrical energy, so it will not produce pollution and radiation. Inverter, power distribution cabinet and other electronic devices have passed the EMC (electromagnetic compatibility) test, so there is no harm to human body. 5. How to clean photovoltaic modules? Rain washes PV modules, so no special maintenance is required. If there is attached dirt on the panels, you can simply wipe it with a wet soft cloth soaked with water. 6. Is there any risk of electric shock when wiping with water? There is no danger to wipe with water. The photovoltaic power generation system and modules have insulation and grounding protection. However, in order to avoid electric shock injury to people and possible damage to modules caused by wiping under high temperature and strong light, it is recommended to clean the modules in the morning or late afternoon. 7. Can you step on the modules for cleaning? The modules are load-bearing, but they can't be cleaned by stepping on them, which will cause cracks and damage to the modules and affect the service life and power generation contribution of the modules. 8. Is there a lack of electricity when it's cold in winter? The radiation intensity, sunshine duration and the working temperature of photovoltaic modules directly affect the power generation. In winter, the irradiation intensity will be weak and the sunshine duration will be short, so the power generation will be less than that in summer. However, the distributed photovoltaic power generation system will be connected to the power grid. As long as the grid has power, the household load will not be short of power and power failure. 9. Will installing solar panels damage the roof? If installed correctly and done by professionals, your home roof will not be damaged. In fact, the correct installation of the roof photovoltaic system can protect the roof from damage. Some panels can even make your roof look more beautiful and cool. Corigy Solar c...

  • How to select and install solar mounting structure for different ground foundations?
    Oct 12, 2020

    As we all know, the selection of appropriate photovoltaic support is an important link to ensure the safe and efficient operation of the entire photovoltaic solar system. According to the foundation, the installation of ground solar panel mounting system can be roughly divided into two categories:ground pile installation and cement foundation installation. Let's analyze the difference between them: 1.Ground Pile Installation:The advantages of ground pile installation are that:not limited by seasonal temperature,convenient to pull out,and does not affect the reuse of the installation site. It can be roughly divided into two types: Hammered pile:Before installation, geological soil test is needed to determine the appropriate hammering depth. Then measure the distance and drive the pile into the ground directly with a pile driver. This method is fast and adaptable. The round pipe, rectangular pipe, sigma type and H-type pipe shown in the figure below are applicable and can be selected according to the actual situation. The solar mounting bracket in the figure below is the hammered pile installation. Its features are: the pile is driven into the ground directly with a pile driver, which is fast; the parts and components are well matched,so the installation is convenient;and the maintenance and repair are convenient. Ground screw:when the ground of installation site is too hard or there are too many crushed stones so the pile cannot directly hammer into the ground, we will choose the ground screw installation. The ground screw is driven into the ground and the structure is fixed on it.The combination of ground screw structure is flexible and diverse, and its application range is wide. The common ground screw bracket can be seen in the figure below. The solar mounting system in the figure below is the ground screw installation. Its advantages are: spiral ground pile is used to adapt to various types of geology; the beam is made of aluminum rail with strengthened design;and the installation and fixation of components are simple and convenient. 2.If the installation site is not suitable for plug-in piles, cement foundation can be selected for installation. The advantages of cement foundation installation are that it is not affected by the ground soil and is very stable. It can be mainly divided into the following two types: Precast cement block foundation: according to the wind speed of the project site, the counterweight of the cement foundation can be calculated,then the cement block can be made in advance refer to the data. After transporting the cement block to the project site,you can fix the bracket on the cement block with bolts. Directly fixed with cement: another form of cement foundation is to directly pour cement on the support in to ground. Compared with the above cement block foundation, this method saves the time of bolt connection and fixation, but requires higher positioning accuracy of supporting pile during pouring. CORIGY SOLAR is a pr...

  • Why Choosing Zinc Aluminum Magnesium Coated Steel As Your Solar Mounting Structure
    Sep 22, 2020

    In the past ten years, solar energy has been rapidly developed and widely applied in the photovoltaic markets. With the increasing awareness of environmental protection, consumers' willingness to install photovoltaic products has gradually increased, which not only improves the environment, but also promotes the progress of photovoltaic technology. There is an urgent need to find a high-quality material that should be as light as possible, reduce the load on the building, ensure the beauty of the bracket,service life of up to 25 years and do not need to maintain the bracket frequently.Zinc Aluminum Magnesium steel is a good choice. The chemical composition of the Zinc Aluminum Magnesium steel is: 11% aluminum, 3% magnesium and the remaining all zinc. Due to the compound effect of these elements, the corrosion inhibition effect is further improved. In addition, it has excellent processing performance under severe conditions such as stretching,stamping,bending, painting,welding, etc.). It has a hard coating and excellent damage resistance performance.Compared with ordinary galvanized and aluminum-zinc coating products, it can achieve better corrosion resistance.And even if you use a hard tool to scratch or destroy the protective film on the surface of the steel,it’s self-healing property will solve this problem in a short time. Solar photovoltaic supports need to have a highly corrosion- resistant as it’s exposed to wind,rain and snow.Especially now that environmental problems such as acid rain and air pollution are becoming increasingly severe. The Zinc Aluminum Magnesium steel is composed of a dense alloy coating. It is the most precise and best coating material. Under the same coating, the service life of Zinc Aluminum Magnesium steel is 10-20 times that of galvanizing steel. It has a long service life, and the coating at the incision site has self-healing properties. It does not require post-dipping and post-processing procedures, which effectively guarantees the life of the bracket for more than 25 years. The advantage of using Zinc Aluminum Magnesium steel in the photovoltaic industry: 1.Good paint adhesion 2.Cutting edge self healing property 3.Scratch resistance 4.Rub resistance 5.Coating peel resistance
