A new national partnership to mobilize solar customers

Vote for solar and solar joint neighbors to announce the establishment of a new national partnership to mobilize solar customers as a political constituency. The partnership today launched a “I Love My Solar” postcard event that provides solar customers with a fun and easy way to send personalized messages to state and federal elected officials and become part of the National Clean Energy Campaign. .z profile steel

“There are nearly 2 million households and businesses across the country taking solar energy. These are Republicans and Democrats, rural and urban families, and many others who unite to use local sunshine to reduce energy costs and build a better world for future generations, “Anya Schoolman, executive director of Solar United Neighbors, said. “We are excited to work with Vote Solar and industry partners, large and small, to help these solar components play a stronger role in influencing their energy decisions.”

A new national partnership to mobilize solar customers

“Public opinion polls show that strong Americans want to provide more solar energy to our country, regardless of political inclinations, but their voices often disappear during the policy making process. Together with Solar Union’s neighbors, we hope to change that. First, let solar customers easily say solar energy and become part of a more powerful clean energy campaign in all 50 states,” said Rosalind Jackson, general manager of voting foreign relations. Solar energy.

The ilovemy.solar website enables solar customers to easily personalize their own elected officials and provide their own pro-Sun newspaper: state legislators, governors and members of Congress. The online platform allows participants to easily upload photos of their solar systems and customize their own solar support information. This digital content is then converted to a physical postcard and mailed to the appropriate decision maker. Actors have the opportunity to participate in ongoing grassroots advocacy and sports construction activities with voting solar and solar joint neighbors. The event will leverage and complement the advocacy and organizational capabilities of the Solar and Solar Joint Neighbors, which have decades of combined experience in implementing solar policy across the country.c profile steel manufacturer

Abigail Rose Hopper, President and CEO of the Solar Industry Association, said: “I like my solar activity is an exciting way for solar customers to express their opinions in important state and federal government policy debates. “Solar customers, including a wide range of Americans, can support activities such as extending solar investment tax credits and promoting national policies that use more solar energy. The country’s 2 million solar customers are growing rapidly, and we want to ensure that across the country Policy makers can hear their voices loudly and clearly.”

The “I love My Solar” postcard event is being launched and more and more leading solar industry partners are involved, including SEIA, SunPower and Sunrun. Vote Solar and Solar United Neighbors are committed to providing this customer engagement tool to solar industry participants of all sizes in all 50 states.

What is cold-formed steel

Cold-formed steel refers to a finished steel product of various cross-sectional shapes bent by a steel plate or a strip steel in a cold state. Cold-formed steel is an economical thin-section thin-walled steel, also known as steel-refrigerated curved or cold-formed profiles. Cold-formed steel is the main material for making lightweight steel structures c profile steel suppliers. It has a variety of extremely thin, well-shaped and complex sections that cannot be produced by hot rolling.

What is cold-formed steel

Use of Cold-formed steel:

Cold-formed steel-based steel companies. Cold-formed steel is widely used in foreign construction industry and is used as urban rail transit, subway, three-dimensional garage, roof truss, purlins, trusses, rigid frames, wall frames, keels, roof slabs, wall panels, slabs, doors and windows, and even containers. Pipes, cofferdams, steel sheet piles, breakwaters, etc.

Compared with hot-rolled steel, the radius of gyration can be increased by 50-60% and the moment of inertia of the section can be increased by 0.5-3.0 times in the same cross-sectional area, so that the material strength can be used reasonably; That is to say, the steel structure made of the traditional I-beam, channel steel, angle steel and steel plate can save about 30 to 50% of the steel. The important feature of cold-formed steel is that it is an economical section steel, which can produce various complicated sections. It mainly improves the section strength by changing the section shape of the section steel.

In recent years, reticulated shells, shelves, single-story and multi-storey houses with cold-formed steels have also developed rapidly. In developed countries, the construction industry is a large user of cold-formed steel, cold-formed steel accounts for 5% of total steel, cold-formed steel for construction industry accounts for more than 70% of cold-formed steel, and cold-formed steel products are used in construction. Mainly used for cold-formed rectangular tubes for structural use and cold-formed steel for construction. From the perspective of structural mechanics and economy, cold-formed steel and H-shaped steel are combined in the construction industry to be a combination, which can realize the industrialization of industrial plants and residential buildings.

The most complete list of solar advantages

A study published today provides the most complete list of solar advantages – from carbon sequestration to pollinator habitat improvement – ​​and provides an important new framework for analyzing solar projects to better understand the full range of benefits.

Nature Sustainability’s peer-reviewed study was conducted by researchers at the Center for Biodiversity, University of California, Davis, and 11 other organizations. It proposes a framework that can more fully understand and ultimately quantify the benefits of solar energy and identify 20 often overlooked advantages. For example,z profile steel manufacturer, solar panels paired with native plant restorations can increase habitat and increase panel efficiency.

The most complete list of solar advantages

“Solar is more beneficial than most people think,” said Greer Ryan, co-author of the center’s renewable energy and research experts. “We hope that utilities, regulators and legislators will now be able to better understand the importance of solar energy. This will lead to the expansion of rooftop solar energy, more community solar development and low prices for everyone.”

This study is the first of its kind. It also marks a partnership between the Center and the University of California at Davis to advance the future of “wild energy”, emphasizing that solar systems benefit not only humans but also the potential of the entire planet.

“The first step in creating a wild energy future is to understand the true value of solar energy,” said Dr. Rebecca R. Hernandez, assistant professor of the John Muir Environmental Research Institute at the University of California, Davis, and the first author of the paper. “By focusing on all the benefits of renewable energy, we can begin to build an energy system that benefits people, wildlife and wildlife.”

In the report the authors:

Establish a framework to describe the 20 benefits of different space installations, including rooftop solar energy, solar energy on contaminated land, solar energy over functional water bodies such as reservoirs, water treatment zones and irrigation channels, and solar energy coexisting with agriculture and grazing;steel c profile manufacturer

Understanding that as renewable energy development accelerates the response to the climate crisis, it should not have unnecessary negative impacts, especially when technology and resources can be used to maximize positive impact; and

It is recommended how the framework can play a role in policy and regulatory decisions to ensure a sustainable energy transition.

The basic detail of galvanized z profile steel

The base material of the galvanized z profile steel is a cold-rolled steel sheet as an original plate, and a hot-dip galvanized coating is formed on the surface of the original plate, that is, a plated plate, and an organic coating is applied on the surface of the plated plate to form a coated plate. The coated plate is subjected to rolling cold bending, and the formed steel plate having a wave-shaped cross section along the width direction of the plate is a pressed color steel plate. Cold rolling is processed from hot-rolled sheets at room temperature, although the steel sheet is heated during the processing because of rolling, although it is called cold rolling.

The basic detail of galvanized Z-profile steel

Zinc-plated Z-shaped steel is cold-rolled due to continuous cold deformation of hot rolling. The mechanical properties are relatively poor and the hardness is too high. It must be annealed to restore its performance. The unannealed is called rolling hard roll. Annealing is a metal heat treatment process in which the metal is slowly heated to a certain temperature for a sufficient period of time and then cooled at a suitable rate. The purpose is to soften the material or workpiece that has been cast, forged, welded or machined, to improve plasticity and toughness, to homogenize the chemical composition, and to remove residual stress. The use of cold-rolled oil can effectively reduce the friction coefficient, low rolling energy consumption, high surface brightness and uniform rolling thickness; good cooling effect, can quickly take away rolling heat, protect rolls and rolled parts; good annealing performance, will not Produces oil burning phenomenon; has short-term anti-rust performance, can provide temporary rust protection for rolling stock.

Zinc-plated Z-shaped steel is an ideal steel material that can be used to make many products, including welded balls. Then everyone knows how to use C-shaped steel to make welded balls? It seems that it is still necessary for experts to introduce us. There are two types of methods for making solder balls, one is hot rolling and the other is cold rolling. The welding balls appearing on the market are basically hot rolled. First, the steel plate blank is hot rolled into a hemisphere, and then a sphere is formed by means of loading and unloading processing and assembly welding. The welded ball produced in this way has a fatal weakness, which is easy to produce uneven wall thickness. As for the roundness of the C-shaped steel ball, it must be controlled in the state to avoid large errors. Otherwise, it will not only affect the assembly size of the ball, but also cause the node to be eccentric, making the finished ball diameter smaller.

One of the development directions of galvanized Z-shaped steel is to continuously meet the needs of various applications and achieve multiple functions on the product. Electrical control cabinet column profiles, shelf profiles, etc. need to be pre-punched before forming. Due to the high geometrical requirements of the hole pitch and the hole, it is not allowed to produce large deformation during the bending process. Therefore, the simulation research and control measures of the pre-punching hole shape distortion of the cold bending machine are very important. Taking the pre-punched sheet as an example, a new method for controlling the distortion of the hole shape during cold forming of the cold bending machine was obtained by field experiment. Steel Profile suppliers

The mechanism of the hole distortion was analyzed and the experimental results were summarized. At the same time, the computer simulation software was used to simulate the machining process, and the field experiment results were compared with the computer simulation results. The working principle of the application is mainly to place the steel on the cold bending machine, and after contacting the roller driven by the reducer, the pressing handle is fed tightly to start the motor oil pump set, and the high pressure oil output by the electric oil pump passes through the overflow valve. In this process, the required pressure can be adjusted to enter the poly-block into the electro-hydraulic valve. The electro-hydraulic valve and the jog switch control the cylinder to work, the working cylinder advances, and the I-steel and the three supporting rollers are pressed without bending. When the deformation starts, the length of the cylinder re-propulsion is 10mm-15mm every time. The main motor is turned forward or reversed. The main motor drives the I-beam to work repeatedly.
