How You Can Build Your Own Solar Panels

Le 20 décembre 2017, 08:24 dans Humeurs 0

The world wide web is full of do-it-yourself (DIY) electronic books, forums and websites on the topic of homemade solar panels. You'd imagine that every person would have homemade solar panels on their residence with all this information.

One setback is that majority of the people do not recognize whether they really have the essential skills or equipment required to create their own solar panels. Add to that the fact that many homemade solar panels can end up costing as much as pre-made ones when it's all said and done and it's obvious why DIY solar panels aren't popular.

The great news is that it is simpler than most people think. The most difficult job is getting past the initial barrier of speculating if you can do it. Homemade solar panels can be a fun and rewarding DIY project for the entire family as well.

There are 3 major divisions of the solar panel - solar cells, a container, and electronics such as solar wire and control units.

The box or container is the most complicated division of the solar panel.The cells is hit by sunlight on one one side and power is created Most solar systems are direct current so the wiring is fairly straightforward.No knowledge of electronics is essential since most of the controllers, inverters, ready made

However, the boxes have to be clear on one side (where the cells "look out" towards the sky), must be weather proof, relatively shock proof, and light enough that they are easily handled for moving and mounting. The boxes must also have gaps for control cables to exit, a way for someone to access them again to service the solar cells should they need it, etc. Most of the time, when something on a solar system breaks down, it is the panel boxes and not the cells themselves that have the problem.

So building or purchasing a tough, well-bulit boxes is important. Light Steel, aluminum and plastics are the most frequent supplies used to create the boxes. Glass or clear plastic are most often the covering for the top is also most common.

When acquiring ready-made solar panels, the cells are usually the most pricey component. When building your own panels, however, you will probably discover that the boxes were the most expensive component. Once made, test them in detail for weatherproofing before installing the solar cells.

Solar cells can be purchased in ready made panels, wired in a series, or they can be bought individually and rubber cable in a series. Most do-it-yourself panel builders will buy separate cells, as they are often inexpensive and effortless to find. A lot of online stores sell stained, damaged, or otherwise unsatisfactory solar cells at a huge sale. Those with some knowledge of the cells can get these and often fix them or make them usable for their project. If you don't have that kind of knowledge, you are better off getting new cells that have a warranty and which are compatible with one another so you can merely plug them together to string a series.

Most of the time, they will be purchased in "bricks." These are small series of pre-wired cells that can be connected, in turn, with other bricks to make more. They are usually sold in voltage quantities, so a brick might have 1/2 volt (V), a full V, or some other variation. As an example: to charge a car battery (12V), you will need between 16 and 18V. Keep in mind that the voltage measurement for your brick is it's maximum production. In most of the U.S., you can expect to get 50-75% efficiency from a solar panel. Bear in mind when building your series.

Other factors to consider include how to electrical power cable in series and how to add voltages to estimate totals when doing so. Soldering skills are a must for creating solar panels, but are not hard to learn. Purchase some low-cost electronics at a thrift and attempt wiring them together or joining them - such as toys remote controlled cards and make sounds like talking teddy bears. This inexpensive practice will pay off when dealing with costly cells later.

Lastly, handle all of homemade solar panels with care while putting them together. You can easily get in to removing and replace a brick or fix a connection in the panels if you leave plenty of room after assembling in between the cells.

Tips to Reduce Welding Wire Accidents

Le 13 décembre 2017, 07:47 dans Humeurs 0

Welding is a manufacturing process that is used extensively in equipment manufacturing. Welding involves applying heat and flux to 2 metal pieces and fusing them together into one single homogenous joint. Welding can be MIG or TIG and performed manually or robotically. There are many parts, both in equipment and consumables, that are required to perform a welding operation. Weld gas is one such solar wire supply. A high voltage power supply is also required to provide the electrical energy required to produce the weld arc needed to melt the material.

MIG welding uses a very different technique than other types of welding. Welders need to observe safety precautions in order to protect themselves and those around them.

? Fire proof your surroundings. Keep your welding area free of paper, plastic, sawdust and other flammable materials. Make sure a fire extinguisher is close at hand and ready to use.

? Protect your eyes. The MIG process produces an intensely bright light that can burn the cornea. Wear a full face control cable mask while using the arc.

? Protect skin from UV light. The MIG welding process generates light with a strong UV component. It's essential to wear gloves and to cover as much of your body as possible in order to avoid sunburn. Protective clothing serves a dual purpose since this type of welding is far more likely to spit out dangerous globules of molten metal.

? Ensure proper ventilation. MIG arcs give off ozone, while aluminum and its alloys give off fumes that can lead to heavy metal poisoning. Leave the garage door open and if you're working for extended periods of time, wear a vapor mask.

MIG (Metal Inert Gas) is a type of specialty rubber cable referred to as an arc welding process, first developed in the 1940s for working with soft metals such as aluminum and copper. The MIG process doesn't deploy traditional welding rods as such, but instead uses a welding gun, a unit to advance welding cable, a power supply, an electrode welding wire and a protected gas supply. You can shop for this equipment and other welding supplies online at various related internet websites.

One of the most popular trades out there today is that of a welder. Welding can be a very difficult task. That is why no one should attempt to weld if they do not know what they are doing. If you are one of the people that know how to weld than you know that there are many different supplies that are needed when it comes to welding. Often times welding supplies can be hard to find and if you do find them they are really over priced. One of the best ways to find all of your supplies would be to look online. You will be able to find just about everything you could ever need when it comes to electrical power cable. The best thing about it is that you can get the stuff delivered right to your door. Also you will be amazed at how much cheaper you can get some of the stuff online rather than at the local store.

Welding is an incredibly demanding profession and the need to adopt appropriate safety measures to stay safe at all times. Let us take a look at the must-have Welding supplies you need at your Welding shop. Safety is definitely the first priority when it comes to Welding. There are different array of health hazards that you need to be careful about as a welder. The intense amount of light generated during the Welding process, is not only harmful to the eyes but also the skin. The first thing that you need to have in your Welding supplies is a basic protective Welding suit.

Cables Used For Welding Machines

Le 11 décembre 2017, 08:24 dans Humeurs 0

This is a very specific house electrical wiring used for welders called "welding cable". Yes, it's as simple as asking your supplier for welding cable and they will ask you what color insulation and what AWG size you need. There is typically black and red in stock and you can get orange from most suppliers at a slightly higher price.

Residential Welders

Welders used in garages and small shops usually use the smaller AWG sizes of electrical wire size because they don't require as much power as larger welding machines. Smaller gauge sizes are 6 AWG, 4 AWG and 2 AWG which are cut-to length on many websites online. That means you can buy 84 feet if your application requires that amount. Simply input the quantity, pick the color and on some website you'll be able to get free shipping on order over $250.

Commercial Welders

Larger welding machines used larger cables because they require more power. Be careful because some industrial applications also require approvals, more protection and even more flexibility. Industrial applications have much more going on in the warehouse, or job site, such as multiple welding machines, large equipment and outdoor environmental conditions to worry about.

The industrial style power cable manufacturers is referred to as Super Vu-Tron which comes in an orange color jacket for safety reasons. It has UL, CSA and MSHA approvals so that it's much easier to pass inspection when necessary. The insulation is much more durable for added industrial use and daily ware and tare. Super Vu-Tron also uses 34 AWG copper strands instead of 30 AWG copper strands for added flexibility.

Cable Colors

If you're looking for a color of welding cable other than black, red or orange you may be required to purchase a minimum amount and wait about 4-6 weeks. It will have to be manufactured from scratch and, in order for it to be worth it for the manufacturer, there will need to be a minimum amount purchased. Now, your supplier may work with you by purchasing the minimum amount and splitting it with you, since they probably get many requests for it each day.

Cable Lugs

Many suppliers will also have the ability to terminate lugs on each end of the armored cable for you. Lugs can be expensive, depending on the AWG size you're going to be working with, so make sure you ask questions and understand everything about your purchase before buying it. When suppliers add lugs to the cable it may take an additional week or two to receive the product.
