veterans - Sunshine could be the primary energy source in the world and sunlight can be converted into electricity using solar power panels. Electricity is now indispensable in life. It powers the machines that many us use daily.

So, what exactly are solar power panels? Imagine if you may earn your personal?

In this article, we are going to show you an easy way of building your individual functional solar panel.

The ingredients

A solar panel is normally constructed from six (6) components namely the PV (photovoltaic) cell or solar cell which generates the facility, the glass which provides coverage for and protects the solar panels, the frame which provides rigidity, the backsheet in which the solar cells are laid, the junction box the place that the wirings are enclosed and connected, along with the encapsulant which can serve as adhesives.

Because most people doesn't have access to equipment in manufacturing solar panel systems, you will need to note and understand those six components to ensure that anyone to have the ability to plan the types of materials required to produce a do-it-yourself or home-made screen.

The types of materials needed on the way to produce a solar panel have to be available to buy locally or on the internet and shouldn't exceed the expense of a new solar panel or does not take a long time to build.

1.) PV Cell

One thing to consider when building your own personal solar panel is the solar cell.

Photovoltaic (PV) cell or solar panel converts visible light into electricity. One (1) solar panel however is not enough to produce a usable amount of electricity just like the microbot in Baymax (Hero 6) which only becomes useful when combined like a group. This basic unit generates a DC (household power) voltage of 0.5 one volt even though that is reasonable, the voltage remains to be too small for some applications. To generate a useful DC voltage, the solar panels are connected in series then encapsulated in modules making the screen. If one cell generates 0.5 volt which is linked to another cell in series, these two cells should then manage to produce 1 volt plus they may then be called a module. A normal module usually consists of 28 to 36 cells in series. A 28-cell module should be able to produce roughly 14 volts (28 x 0.5 = 14VDC) that's enough to charge a 12V battery or power 12V devices.

Connecting two or more cells require that you've a basic knowledge of series and parallel connection which is similar to connecting batteries to produce up an assortment storage system.

There's two most common cells that can be bought in the market; a monocrystalline cell as well as a polycrystalline cell. Those two will surely have exactly the same size, 156mm x 156mm, but the main difference could be efficiency. It is important to purchase additional cells to serve as backup in the event you fail on a number of the cells i.e. bad solder, broken cell, scratched, etc.

Monocrystalline solar cells are often black and octagonal in shape. This kind of solar cell is made from the greatest and purest grade silicon making them expensive. However they are the most beneficial of all of solar cells and they are typically selecting solar contractors when space is a factor to look into in experienceing the power they would like to attain based on their solar system design.

Polycrystalline Solar cells are seen as their bluish color and rectangular shape. These cells are manufactured within a easier process which lowers the purity of the silicon content and also lowers the efficiency in the product.

Generally, monocrystalline cells are more efficient than polycrystalline cells but this doesn't imply that monocrystalline cells perform and outputs more power than polycrystalline cells. Solar panel efficiency has connected with the dimensions of the cells and each solar power or cells offer an efficiency rating determined by standard tests once they were manufactured. This rating is often in percentage as well as the common values vary from 15% to 20%.

2.) Glass

The glass protects the Electricity cells while allowing optimal sunlight to give. These are usually manufactured from anti-reflective materials. Tempered glass could be the selection of material nowadays even for unknown and new manufacturers though there continue to be people who utilize flat plate glass on his or her solar power systems. Tempered glass are made by chemical or thermal means and is more often than not stronger than plate glass which makes it more expensive to produce however the tariff of manufacturing them today is cheap and cost-effective. Flat plate glass creates sharp and long shards when broken in contrast to tempered glass which shatters safely in small pieces upon impact, that is why they also call it safety glass. It should be noted here that most amorphous solar panel systems uses flat plate glass with the way the panel is made.

Tempered glass 's what manufacturers used in mass producing their solar panels. In our DIY project, we recommend to use Plexiglas also referred to as acrylic glass which can be safer than the regular normal glass from your local shop. It's kind of expensive than regular glass but is safe from nature's elements and doesn't break easily. The Plexiglas can even be screwed or glued easily for the frame.

3.) Frame

A frame is normally made of anodized aluminum which offers structure and rigidity on the solar module. These aluminum frames are also built to be works with most solar mounting systems and grounding equipment for simple and safe installation over a roof or on the ground.

The frame inside a factory-built cell is truly the aluminum part where all four sides of the cell sheet are inserted. Refer to it a skeletal rectangular frame. The solar power sheet mind you is composed of one other 4 components and therefore are layered and laminated inside the following order throughout; the tempered glass, top encapsulant, the solar panels, bottom encapsulant, then a backsheet. Inside our DIY solar power, i will be employing a wooden frame and the end-result could be something analogous into a picture frame the place that the picture may be the solar cells glued to some non-conductive board, the glass for the Plexiglas top cover, and also the wooden part as the frame and backsheet.

4.) Backsheet

The backsheet is the layer of plastic film for the back top of the module. Here is the only layer protecting the module from unsafe DC voltage. The main aim of the backsheet would be to insulate and protect the handler from shock and provide the safest, efficient, and dependable electrical conductivity possible.

The backsheet is a wooden plywood in which the frame is going to be screwed ahead and so on the sides. It must be noted here that a perforated hardboard (Pegboard) will probably be used to place and align the Solar cells which Pegboard will sit down on the top wooden backsheet and fitted inside wooden frame.

5.) Junction Box

The junction box is the place the terminal wires and bypass diodes are situated and concealed. The terminal wires are basically the bad and the good wires based on the series connections of the PV Cells and can be connected to another solar panel, electrical controller, an assortment system, in order to an inverter, based on the system design. The bypass diode is really a protective mechanism that prevent power from okay the solar panel if it is not producing electricity as in true when it's night time.

You will find junction boxes made for factory-built solar power systems which can be now available to buy online especially from China. If you aren't short on time, you can order on the internet and wait for delivery or else you can just obtain a regular electrical junction box out of your local home improvement store. The intention of the junction box is always to protect the terminals (negative and positive terminals) from water, dust, as well as other elements. This is where the two wires (red for positive and black for negative) is going to be via. One other end of the wires may also be paid by utilizing a PV accessory called MC4 which may be purchased online alongside the PV junction box.

6.) Encapsulant

Encapsulant sheets prevent water and dirt from infiltrating the solar modules and serve as shock-absorbers that protect the Electricity cells. They've got this adhesive bonding capacity to the glass, the PV cells, and the backsheet similar to a glue but stronger. Encapsulants are generally made from Ethylene-Vinyl Acetate or EVA and they are applied using lamination machines and operations. Cell manufacturers utilize a vacuum along with a large oven to properly seal and cure the EVA sheet on the solar power systems. Many of us don't have the power to try this but some still have tried and failed while others had varying amounts of success.

Encapsulants are thin plastic sheets that are usually laminated at the top and bottom aspects of the solar cell sheet. The underside encapsulant is the layer in the backsheet the place that the solar panels are actually placed and supported. In our project, we are going to instead utilize a latex acrylic paint. This paint won't be placed on the solar cells because when attempted, will not lead to an identical distribution or application of the liquid on the top of the cells that may degrade performance. The paint will be applied to the wooden frame, wooden backsheet, also to the Pegboard. This Latex Acrylic paint are able to protect the wooden parts from UV rays which enable it to better resist blistering and cracking overtime. This paint, although water-soluble, can dry quickly and becomes water-resistant.
