air pollution - Sunlight could be the primary energy source on this planet and sunlight could be converted right into electricity using solar panel systems. Electricity is now indispensable in your life. It powers the machines that many us use daily.

So, precisely what are solar power systems? Suppose you can create your individual?

In this post, we will explain to you an easy way of building your own personal functional solar panel.

The ingredients

A solar panel is often made of six (6) components namely the PV (photovoltaic) cell or solar cell which generates the electricity, the glass which takes care of and protects the solar panels, the frame which offers rigidity, the backsheet in which the solar cells are laid, the junction box the location where the wirings are enclosed and connected, and the encapsulant which is adhesives.

Because most people won't have usage of equipment in manufacturing solar power systems, it is important to note and understand those six components to ensure that that you be able to plan materials had to develop a do-it-yourself or home-made cell.

Materials needed on the way to create a solar panel must be available for purchase locally or on the internet and ought not exceed the expense of a fresh solar panel or doesn't take too much time to build.

1.) PV Cell

Think about consider when building your own cell could be the solar panel.

Photovoltaic (PV) cell or solar panel converts visible light into electricity. One (1) solar panel however isn't enough to create a usable volume of electricity such as microbot in Baymax (Hero 6) which only becomes useful when combined as being a group. This basic unit generates a DC (dc) voltage of 0.5 to at least one volt even though this really is reasonable, the voltage remains to be too small for most applications. To make a useful DC voltage, the solar panels are connected in series after which encapsulated in modules making the solar power. If someone cell generates 0.5 volt and is connected to another cell in series, those two cells should then be able to produce 1 volt plus they will then be known as a module. A typical module usually is made up of 28 to 36 cells in series. A 28-cell module are able to produce roughly 14 volts (28 x 0.5 = 14VDC) that's enough to charge a 12V battery or power 12V devices.

Connecting a couple of cells require that there is a basic understanding of series and parallel connection which has similarities to connecting batteries to create up an assortment storage system.

There's two most common solar cells that can be purchased on the market; a monocrystalline cell and a polycrystalline cell. Both of these may have exactly the same size, 156mm x 156mm, nevertheless the main difference can be efficiency. You will need to purchase additional cells for everyone as backup in case you fail on many of the cells i.e. bad solder, broken cell, scratched, etc.

Monocrystalline solar panels are often black and octagonal in shape. This type of solar panel consists of the highest and purest grade silicon causing them to be expensive. But they're the perfect of all types of cells and are typically the choice of solar contractors when space is a the answer to look into achieving the power they need to attain determined by their solar system design.

Polycrystalline PV Cells are seen as a their bluish color and rectangular. These cells are made within a much easier process which lowers the purity of the silicon content as well as lowers the efficiency with the end product.

Generally, monocrystalline cells will be more efficient than polycrystalline cells however does not mean that monocrystalline cells perform and outputs more power than polycrystalline cells. Solar panel efficiency has something related to the dimensions of the cells every screen or cells offer an efficiency rating based on standard tests whenever they were manufactured. This rating is often in percentage along with the common values range from 15% to 20%.

2.) Glass

The glass protects the Electricity cells while allowing optimal sunlight to secure. These are typically created from anti-reflective materials. Tempered glass could be the choice of material nowadays even for unknown and new manufacturers although there remain those that utilize flat plate glass on their solar panels. Tempered glass are set up by chemical or thermal means and it is often times stronger than plate glass so that it is more expensive to create but the price 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 additionally, they think of it as safety glass. It should be noted here that most amorphous solar power panels uses flat plate glass with the way the panel is made.

Tempered glass is exactly what manufacturers used in mass producing their solar power systems. In your DIY project, we advise to utilize Plexiglas otherwise known as acrylic glass that's safer compared to the regular normal glass from the local home improvement store. It's kind of expensive than regular glass but is safe from nature's elements and doesn't break easily. The Plexiglas can also be screwed or glued easily to the frame.

3.) Frame

A frame is generally made from anodized aluminum which gives structure and rigidity towards the solar module. These aluminum frames will also be built to be suitable for most solar mounting systems and grounding equipment for simple and safe installation on the roof or in the grass.

The frame inside a factory-built solar power is often the aluminum part where all sides from the screen sheet are inserted. Think of it as a skeletal rectangular frame. The solar panel sheet in addition is made up of one other 4 components and so are layered and laminated inside the following order all the way through; the tempered glass, top encapsulant, the solar cells, bottom encapsulant, then the backsheet. In our DIY cell, we are utilizing a wooden frame along with the end-result will be something analogous with a picture frame the location where the picture is the cells glued to a non-conductive board, the glass for that Plexiglas top cover, and also the wooden part because the frame and backsheet.

4.) Backsheet

The backsheet may be 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 function of the backsheet is always to insulate and protect the handler from shock and supply the safest, efficient, and dependable electrical conductivity possible.

The backsheet will be a wooden plywood where the frame will be screwed ahead and also on the edges. It should be noted here which a perforated hardboard (Pegboard) will probably be accustomed to place and align the Solar cells and this Pegboard will lay on the surface of the wooden backsheet and fitted inside wooden frame.

5.) Junction Box

The junction box is how the terminal wires and bypass diodes are located and concealed. The terminal wires are basically the good and bad wires based on the series connections with the Solar cells and could be associated with another solar power, electric power charge controller, an electric battery system, or an inverter, with respect to the system design. The bypass diode is a protective mechanism that prevent power from ok the solar power when it's not producing electricity like the case when it is nighttime.

You will find junction boxes suitable for factory-built solar panels which can be available these days to purchase online especially from China. If you're not short on time, you can order web wait for an delivery otherwise you can just get a regular electrical junction box from the local home improvement center. The objective of the junction box would be to protect the terminals (positive and negative terminals) from water, dust, as well as other elements. This is also the place that the two wires (red for positive and black for negative) will be originating from. The opposite end of the wires can be paid by employing a PV accessory called MC4 which may be also purchased online together with the PV junction box.

6.) Encapsulant

Encapsulant sheets prevent water and dirt from infiltrating the solar modules and function shock-absorbers that protect the Solar cells. They have got this adhesive bonding chance to the glass, the Electricity cells, and the backsheet much like a glue but stronger. Encapsulants usually are created from Ethylene-Vinyl Acetate or EVA and therefore are applied using lamination machines and operations. Screen manufacturers make use of a vacuum plus a large oven to seal and cure the EVA sheet on the solar power systems. Many people don't have the capability to try this however, many have tried without success and some had varying levels of success.

Encapsulants are thin plastic sheets which are usually laminated at the top and bottom aspects of the solar panel sheet. Underneath encapsulant may be the layer over the backsheet in which the solar cells are in fact placed and supported. Inside our project, we're going to instead use a latex acrylic paint. This paint won't be put on the pv cells because when attempted, won't bring about the same distribution or application of the liquid towards the top of the cells that may degrade performance. The paint will likely be used on the wooden frame, wooden backsheet, also to the Pegboard. This Latex Acrylic paint should be able to protect the wooden parts from UV rays and can better resist blistering and cracking overtime. This paint, although water-soluble, can dry quickly and becomes water-resistant.
