Building Solar Panels By Ben Levanger

Are you looking to build your own solar panels, probably because the cost of buying a solar panel is through the roof. A typical home uses 300 watts of power per day, and if you were to go and buy sufficient solar panels to produce that amount you would need to spend close to ten thousand dollars. Now for a regular family throwing ten thousand dollars towards some solar panels is not a viable option.
That is why I opted for building solar panels. I will show you want you need, and how to avoid costly mistakes. This seemed a little easier then out wind generator that took us a little while to assemble, but was still quite easy with the guide that we followed.
What you need
- A guide - these are readily available on the net
- Some simple tools and a clean work place
- Make sure the guide is tested, and easy to follow - some guides are complicated and end up taking to much of your time and money
The guide that we used focused on installing solar panels, but there was also a section that covered building your own. We set off and starting following their instructions to the letter. Some of the guides online even talk about how you can sometimes get solar panels for free, but we won't cover that.
First you need something to mount the solar cells on. Preferably a piece of plywood, you can use OSB material but plywood is more durable and last better in the weather. OSB will absorb the water when it rains and this can ruin your project. To build your own solar panels you will need to do some soldering to get the appropriate tool.
Always wear safety equipment, when working
Basically building solar panels is quite easy but you have to know where to get the solar panels. Once you have acquired the solar panels it's a matter of soldering the negative and positives wires to make a completed panel. Once you have done this you can mount the solar panel and run the wires. Depending on how much power you are supplying, you can either hook them up to run your washer and dryer, charge batteries, hook them up directly to your meter. You have a few different options but make sure to find a guide, and follow their instructions.
Let me tell you, its pretty cool to see my meter spinning the other way, yeah its taken some work but I now get checks from the electrical company, and I never have to worry about paying them again. Building solar panels was a fun project.

What is Sheet Metal Fabrication?

The processes and techniques of shaping and bending sheet metals to create a variety of components are known as sheet metal fabrication. All sorts of sections and complex shapes can be given to the sheet metals. All products that contain any metal components will be required to proceed through some type of sheet metal fabrication. Many manufacturing fields such as computer, medical, appliances, or electronics often use this metal fabrication process.

Processes of Sheet Metal Fabrication

Different processes such as forming, cutting, and finishing are used in order to reach the final product in sheet metal fabrication.

Cutting

To fabricate a sheet metal at first it has to be cut into different shapes. Then the pieces are modeled or shaped into final pieces.
Shearing and electrical discharge machining are some of the cutting processes in shearing bigger pieces which are sheared into much thinner pieces. The operation of shear stress on a cutting machine will be needed for this process. In EDM conductive materials will then be melted from an electrode spark which comes from a small fully charged electrode that will be surrounded by iodized water.

Different tools like electrical powered shears and tin snips are often used for cutting sheet metals. Computer based equipments like Computer Numerical Control Punch Press or Computer Numerical Control Lasers may also be used. Tin snips is a hand tool that is required and used on a daily basis by a variety of companies. Electrical powered shears is often used and functional by the help of a battery powered electric motor. It has a crank drive and movable cutting blade for properly cutting sheets of metals. Next a laser light will be pressed across the surface of the metal sheet in order to cut in Computer Numeric Control lasers cuts. In order to cut the metal into different sizes or shapes like square, hexagon and circle the Computer Numerical Control Punch Press will need to be used. Water jets can be used to cut sheet metal as well. It uses the high pressure water ranging from twenty thousand to sixty thousand psi in order to cut the metal properly. It doesn’t generate any type heat while its being used for cutting which is an important factor.

Forming

After cutting the metal sheet, it has to be shaped into its required shape to create a component and this process is known as forming. It refers to the variety of ways that are used to shape sheet metal into a variety of forms. While forming a metal sheet take care of the ductility, ability of the sheet metal to allow it to be manipulated without fracturing.

Rolling, shape flat pieces of metal over and over by the use of roll stands, Bending and forming, hand based process used to get the desired shape on the sheet metal, Punching, used to punch holes in the metal, Welding, used to join pieces of sheet metal together, Stamping, tools and dies are used to stamp designs into the metal, Hardware and fastener creation methods, used to add latches or handles to the sheet metal, are the processes of forming sheet metal.

Finishing

Every sheet metal goods have to go through the process of finishing to eliminate or to polish rough spots and edges.
After going through all of these processes we find finished sheet metal goods.

Now-a-days, with the advancement of technology, many of these techniques are now applied with the use of computer controlled machinery. Instead of opening a factory to create their own metal products, a company might hire a sheet metal fabrication specialist to do the work for them. This gives the company more time to focus on marketing and promotion and can also save money.

Sheet metal work and Its Types



By: Stuart Small

By: Stuart Small

The formation of sheet metal, thin and flat pieces metals of varying thicknesses is known as sheet metal work. Different types of sheet metal works include:

  • Deep drawing

  • Cutting

  • Perforating

  • Spinning

  • Press brake forming

  • Roll forming

  • Rolling

  • Stamping

  • Bending

  • Ironing

  • Wheeling

  • Decambering


Deep drawing

Drawing process where the depth of the part being made is more than half its diameter is known as deep drawing. In this process, metal blank is stretched around a plug then make it move into a die, a molding cutter. Kitchen sink is a perfect example of deep drawing technology. Aerospace, automobile, dairy, lighting, pharmaceuticals, and plastics are the industries that are rely on deep drawing process.

Cutting

To give the sheet metals different shapes it has to be cut into tiny pieces. To cut sheet metals various tools from hand tools to very large powered shears are used. CNC (Computer Numerical Control) and Lasers cutting or multi-tool CNC punch press are the most modern sheet metal cutting processes.

Perforating

Perforating is used to design, produce, and fabricate metal to meet the precise specification. Perforated metal offers a solution that is both decorative and functional.

Spinning

Spinning, performed by hand or by a CNC lathe, is the process in which a disk or tube of metal is rotated at high speed and formed into an axially symmetric part. The process has both artisans and commercial applications. To produce architectural detail, specialty lighting, decorative household goods and urns artisans use the process and among its commercial application include rocket nose cones, cookware, gas cylinders, brass instrument bells, and public waste receptacles.

Press brake forming

In need of a metal housing for a particular part, brackets for machines and equipments, metal framing, and even decorative touches press break forming is used. It is considered as an ideal solution for those who are in need of replacement parts, large numbers of brackets, and fastening solutions as well as prototypes for almost any type of machinery.

Roll forming

The process includes a large strip of metal to be passed through continuous sets of rolls, or stands to collect the needed cross-section profile. For producing parts with long lengths or in large quantities it is an ideal process. The process of roll forming is a simpler one.

Rolling

In this process a metal sheet is passed through a pair of rolls. On the basis of the shape of the final product rolling is classified into two classes-- Flat, shape of the product is either classed as sheet or plate, and Profile rolling, the final product may be a round rod or other shaped bar. Hot rolling and cold rolling are the two types of rolling according to the temperature of the metal rod.

Stamping

Punching by using a machine press or stamping press, blanking, embossing, bending, flanging, and coining are the different operations that are associated with stamping. This is both a single stage and a multiple stage operation.

Bending

Process in which a metal is deforming plastically to change its shape is known as bending. In this process one axis of the material is deformed not the surface area of the material. Press breaks are usually used for bending. As a flexible process it is used for getting different shapes.

Ironing

The process of uniformly thinning the work piece in a specific area is known as ironing in the metal sheet forming.

Wheeling

To use English Wheel to form smooth, compound curves from flat sheets of metal is known as wheeling.

Decambering

The process of removing camber, or horizontal bend, from strip shaped materials is known as decambering. Flattening or leveling processes resemble in decambering.
