What exactly are Solar Panels?

veterans - The sun's rays will be the primary source of energy in the world and sunlight may be converted directly into electricity using solar panel systems. Electricity has become indispensable in everyday life. It powers the machines that many us use daily.

So, what exactly are solar power systems? What if you can create your own?

In the following paragraphs, we're going to show you a basic technique of building your individual functional solar panel.


A cell is usually constructed from six (6) components namely the PV (photovoltaic) cell or solar cell which generates the facility, the glass which covers and protects the solar cells, the frame which provides rigidity, the backsheet in which the solar panels are laid, the junction box in which the wirings are enclosed and connected, and the encapsulant which serves as adhesives.

As most people doesn't need use of equipment in manufacturing solar power systems, it is important to note and understand those six components for that you be able to plan materials had to produce a do-it-yourself or home-made cell.

The materials needed regarding how to create a solar panel should be available to buy locally or on the web and must not exceed the expense of a new solar power or won't take too much time to create.

1.) PV Cell

The first thing to consider when building your own personal screen may be the solar panel.

Photovoltaic (PV) cell or solar cell converts visible light into electricity. One (1) solar cell however is not enough to make a usable amount of electricity just like the microbot in Baymax (Hero 6) which only becomes useful when combined as a group. This basic unit generates a DC (direct current) voltage of 0.5 to at least one volt and although this really is reasonable, the voltage remains to be too small for some applications. To produce a useful DC voltage, the solar panels are connected in series and then encapsulated in modules making the cell. If an individual cell generates 0.5 volt which is linked to another cell in series, these two cells should then be able to produce 1 volt and they will then be termed as a module. An average module usually includes 28 to 36 cells in series. A 28-cell module can 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 solar cells require that you've got a basic understanding of series and parallel connection which is similar to connecting batteries to generate up an assortment storage system.

There are 2 most popular solar cells that can be purchased on the market; a monocrystalline cell and a polycrystalline cell. These two can have exactly the same size, 156mm x 156mm, nevertheless the main difference could be efficiency. It is important to purchase additional cells for everyone as backup in case you fail on a few of the cells i.e. bad solder, broken cell, scratched, etc.

Monocrystalline solar cells are often black and octagonal in form. This type of solar cell is made of the best and purest grade silicon making them expensive. But you are the best of all sorts of solar panels and so are almost always the option of solar contractors when space is a vital the answer to consider in having this power they wish to attain depending on their solar system design.

Polycrystalline Electricity cells are seen as their bluish color and quadratique. These cells are manufactured inside a much simpler process which lowers the purity of the silicon content plus lowers the efficiency of the end result.

Generally, monocrystalline cells are more efficient than polycrystalline cells however, this does not mean that monocrystalline cells perform and outputs more power than polycrystalline cells. Solar cell efficiency has connected with the size of cellular structure and each solar panel or cells have an efficiency rating based on standard tests after they were manufactured. This rating is normally in percentage and also the common values range from 15% to 20%.

2.) Glass

The glass protects the PV cells while allowing optimal sunlight to feed. These are typically created from anti-reflective materials. Tempered glass could be the collection of material nowadays for unknown and new manufacturers though there remain those that utilize flat plate glass on their own solar power systems. Tempered glass are manufactured by chemical or thermal means and is many times stronger than plate glass making it more costly to make however the expense of manufacturing them today is affordable and cost-effective. Flat plate glass creates sharp and long shards when broken instead of tempered glass which shatters safely in small pieces upon impact, that's the reason additionally, they refer to it as safety glass. It ought to be noted here that a majority of amorphous solar panels uses flat plate glass because of the way the panel is constructed.

Tempered glass is what manufacturers use within mass producing their solar panel systems. Within our DIY project, we suggest to utilize Plexiglas also known as acrylic glass which can be safer compared to regular normal glass from a local hardware store. It's kind of expensive than regular glass but is safe from nature's elements and break easily. The Plexiglas can even be screwed or glued easily for the frame.

3.) Frame

A frame is usually made from anodized aluminum which supplies structure and rigidity towards the solar module. These aluminum frames are also built to be appropriate for most solar mounting systems and grounding equipment for simple and safe installation over a roof or on the ground.

The frame within a factory-built solar power is often the aluminum part where all four sides in the solar power sheet are inserted. Consider it a skeletal rectangular frame. The solar power sheet in addition comprises the opposite 4 components and they are layered and laminated in the following order all the way through; the tempered glass, top encapsulant, the cells, bottom encapsulant, then your backsheet. In our DIY cell, we will be using a wooden frame and also the end-result would be something analogous with a picture frame the place that the picture will be the solar panels glued to some non-conductive board, the glass for the Plexiglas top cover, along with the wooden part as the frame and backsheet.

4.) Backsheet

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

The backsheet would have been a wooden plywood the location where the frame will probably be screwed on the top and also on the perimeters. It needs to be noted here a perforated hardboard (Pegboard) will be employed to place and align the PV Cells which Pegboard will sit on the top of wooden backsheet and fitted in the wooden frame.

5.) Junction Box

The junction box is when the terminal wires and bypass diodes can be found and concealed. The terminal wires are basically the positive and negative wires using the series connections from the PV Cells and is associated with another screen, electric power charge controller, an electric battery system, or an inverter, based on the system design. The bypass diode can be a protective mechanism that prevent power from ok the solar panel when it's not producing electricity such as the truth if it's nighttime.

You will find junction boxes made for factory-built solar power systems which are available nowadays to purchase online especially from China. If you aren't tight on time, purchase online and wait for delivery otherwise you can simply obtain a regular electrical junction box from the local home improvement store. The objective of the junction box is always to protect the terminals (good and bad terminals) from water, dust, as well as other elements. This is also where the two wires (red for positive and black for negative) is going to be via. The opposite end of the wires can also be paid by using a PV accessory called MC4 that may also be purchased online with 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 have got this adhesive bonding capability to the glass, the PV cells, as well as the backsheet much like a glue but stronger. Encapsulants are usually manufactured from Ethylene-Vinyl Acetate or EVA and are applied using lamination machines and processes. Solar panel manufacturers work with a vacuum as well as a large oven to correctly seal and cure the EVA sheet onto the solar power panels. Many people will not have the capacity to make this happen but many have tried without success although some had varying amounts of success.

Encapsulants are thin plastic sheets which can be usually laminated at the top and bottom areas of the solar panel sheet. The bottom encapsulant will be the layer over the backsheet where the cells are in reality placed and supported. Inside our project, we'll instead utilize a latex acrylic paint. This paint won't be placed on the electricity cells because when attempted, won't lead to an identical distribution or putting on the liquid for the surface of the cells which may degrade performance. The paint will probably be placed on the wooden frame, wooden backsheet, also to the Pegboard. This Latex Acrylic paint can protect the wooden parts from Ultra violet rays and may better resist blistering and cracking overtime. This paint, although water-soluble, can dry quickly and becomes water-resistant.
