air pollution - Sunshine could be the primary source of energy on this planet and sunlight could be converted right into electricity using solar power systems. Electricity is now indispensable in everyday life. It powers the machines that a lot of us use daily.

So, precisely what are solar panels? Let's say you could make your own?

In this post, we'll explain to you an easy way of building your individual functional solar power.

The parts

A solar panel is often made of six (6) components namely the PV (photovoltaic) cell or solar panel which generates the facility, the glass which covers and protects the solar panels, the frame which supplies rigidity, the backsheet the place that the solar panels are laid, the junction box in which the wirings are enclosed and connected, as well as the encapsulant which is adhesives.

Because most people doesn't have use of equipment in manufacturing solar power systems, it is important to note and understand those six components to ensure that anyone to be capable of plan the type of material needed to produce a do-it-yourself or home-made solar power.

The type of material needed concerning how to make a screen must be for sale locally or online and ought not exceed the expense of a whole new cell or will not take a long time to develop.

1.) PV Cell

One thing to consider when building your individual solar panel is the solar panel.

Photovoltaic (PV) cell or solar panel converts visible light into electricity. One (1) solar panel however isn't enough to make a usable volume of electricity such as 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 to a single volt and even though this can be reasonable, the voltage is still too small for many applications. To make a useful DC voltage, the solar cells are connected in series then encapsulated in modules making the solar panel. If one cell generates 0.5 volt and is also attached to another cell in series, these two cells should then be able to produce 1 volt plus they can then be referred to as 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) which can be 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 make up a battery storage system.

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

Monocrystalline solar cells are generally black and octagonal fit. This sort of solar panel is made of the greatest and purest grade silicon making them expensive. But you are the most beneficial of all of solar cells and are more often than not the choice of solar contractors when space is an important the answer to look into in experienceing the power they need to attain determined by their solar system design.

Polycrystalline Electricity cells are characterized by their bluish color and rectangular. These cells are produced in the easier process which lowers the purity with the silicon content plus lowers the efficiency of the product.

Generally, monocrystalline cells tend to 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 connected with how big cells and every solar panel or cells have an efficiency rating depending on standard tests when they were manufactured. This rating is usually in percentage and the common values vary from 15% to 20%.

2.) Glass

The glass protects the PV cells while allowing optimal sunlight to pass through. These are usually made from anti-reflective materials. Tempered glass is the choice of material nowadays even for unknown and new manufacturers although there remain those that utilize flat plate glass on the solar panels. Tempered glass are created by chemical or thermal means and is also often stronger than plate glass making it costlier to produce however the expense of manufacturing them today is cheap and cost-effective. Flat plate glass creates sharp and long shards when broken rather than tempered glass which shatters safely in small pieces upon impact, that is why additionally, they refer to it safety glass. It ought to be noted here that a lot of amorphous solar power systems uses flat plate glass due to the way the panel is made.

Tempered glass is exactly what manufacturers used in mass producing their solar power systems. Inside our DIY project, we propose to work with Plexiglas also referred to as acrylic glass which is safer than the regular normal glass from your local home improvement center. It's kind of expensive than regular glass but is weather resistant and break easily. The Plexiglas may also be screwed or glued easily for the frame.

3.) Frame

A frame is usually made from anodized aluminum which gives structure and rigidity towards the solar module. These aluminum frames can also be made to be works with most solar mounting systems and grounding equipment for easy and safe installation on the roof or in the grass.

The frame inside a factory-built screen is truly the aluminum part where all 4 sides with the solar panel sheet are inserted. Consider it as a skeletal rectangular frame. The cell sheet mind you consists of another 4 components and therefore are layered and laminated inside the following order all the way through; the tempered glass, top encapsulant, the solar panels, bottom encapsulant, then your backsheet. In our DIY screen, we are utilizing a wooden frame and also the end-result could be something analogous with a picture frame where the picture could be the solar panels glued to some non-conductive board, the glass to the Plexiglas top cover, along with the wooden part because frame and backsheet.

4.) Backsheet

The backsheet will be the layer of plastic film on the back top of the module. This is actually the only layer protecting the module from unsafe DC voltage. The principle purpose of the backsheet would be to insulate and protect the handler from shock and offer the safest, efficient, and dependable electrical conductivity possible.

The backsheet might be a wooden plywood where the frame will be screwed on the top and also on the perimeters. It must be noted here that a perforated hardboard (Pegboard) will be utilized to place and align the Electricity cells and also this Pegboard will sit on the surface of the wooden backsheet and fitted inside wooden frame.

5.) Junction Box

The junction box is the place the terminal wires and bypass diodes can be found and concealed. The terminal wires are just the good and bad wires using the series connections from the PV Cells and could be associated with another solar power, electric power charge controller, a battery system, in order to an inverter, based on the system design. The bypass diode can be a protective mechanism that prevent power from ok the cell if it's not producing electricity like true if it is nighttime.

You can find junction boxes made for factory-built solar panel systems which are available nowadays to buy online especially from China. If you're not pressed for time, you can order on the internet and wait for a delivery or maybe you can easily purchase a regular electrical junction box out of your local hardware store. The intention of the junction box would be to protect the terminals (good and bad terminals) from water, dust, and other elements. This can be the place that the two wires (red for positive and black for negative) will likely be coming from. One other end of the wires can also be paid by utilizing a PV accessory called MC4 which may be also 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 PV cells. They have this adhesive bonding capability to the glass, the PV cells, as well as the backsheet similar to a glue but stronger. Encapsulants are often made of Ethylene-Vinyl Acetate or EVA and so are applied using lamination machines and procedures. Screen manufacturers work with a vacuum plus a large oven to effectively seal and cure the EVA sheet on the solar power systems. Most of us would not have the capacity to do this however, many still need tried without success and some had varying numbers of success.

Encapsulants are thin plastic sheets which are usually laminated on the top and bottom elements of the solar panel sheet. The bottom encapsulant is the layer in the backsheet where the solar cells are actually placed and supported. In your project, we'll instead utilize a latex acrylic paint. This paint are not applied to the electricity cells because when attempted, is not going to cause the same distribution or use of the liquid towards the top of the cells which may degrade performance. The paint will likely be applied to the wooden frame, wooden backsheet, also to the Pegboard. This Latex Acrylic paint should be able to 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.
