The sunlight is the primary source of energy on Earth as well as sunlight can be converted straight into power making use of solar panels. Electrical power has actually become crucial in life. It powers the machines that most us make use of daily.

So, what are photovoltaic panels? What if you can create your own?

In this short article, we will show you a uncomplicated approach of building your own functional solar panel.


A photovoltaic panel is normally produced from 6 (6) parts particularly the PV ( solar) cell or solar battery which generates the electrical energy, the glass which covers and safeguards the solar batteries, the structure which offers strength, the backsheet where the solar cells are laid, the junction box where the wirings are confined and connected, and also the encapsulant which serves as adhesives.

Considering that most individuals does not have access to devices in manufacturing solar panels, it is essential to keep in mind and also understand those 6 elements in order for any person to be able to prepare the materials required to develop a do-it-yourself or home-made solar panel.

The products needed on just how to make a photovoltaic panel should be offered for purchase locally or online as well as ought to not go beyond the price of a new solar panel or does not take a long period of time to build.

1.) PV Cell

The first thing to consider when building your very own photovoltaic panel is the solar battery.

Photovoltaic Or Pv (PV) cell or solar battery converts visible light into power. One (1) solar battery however is insufficient to create a useful quantity of power just like the microbot in Baymax (Hero 6) which just ends up being valuable when integrated en masse. This standard device creates a DC (direct present) voltage of 0.5 to 1 volt as well as although this is reasonable, the voltage is still as well little for the majority of applications. To create a useful DC voltage, the solar cells are linked in collection and afterwards encapsulated in modules making the photovoltaic panel. If one cell creates 0.5 volt and also is connected to an additional cell in series, those 2 cells need to then be able to produce 1 volt and also they can after that be called a component. A common component usually consists of 28 to 36 cells in series. A 28-cell module ought to be able to produce about 14 volts (28 x 0.5 = 14VDC) which suffices to charge a 12V battery or power 12V tools.

Connecting two or more solar cells require that you have a basic understanding of series and also identical link which resembles connecting batteries to make up a battery storage space system.

There are two most usual solar cells that can be bought on the market; a monocrystalline cell and also a polycrystalline cell. These 2 can have the very same dimension, 156mm x 156mm, but the primary difference would certainly be efficiency. It is necessary to purchase extra cells to work as backup in case you fail on some of the cells i.e. bad solder, damaged cell, damaged, and so on

. Monocrystalline solar batteries are normally black and octagonal in shape. This kind of solar battery is made of the highest and also purest grade silicon that makes them pricey. Yet they are the most efficient of all sorts of solar cells as well as are often the selection of solar service providers when space is an important element to take into consideration in accomplishing the power they intend to obtain based on their solar system style.

Polycrystalline PV Cells are defined by their blue color and also rectangular shape. These cells are manufactured in a much simpler process which decreases the pureness of the silicon content as well as likewise reduces the performance of completion item.

Typically, monocrystalline cells are much more reliable than polycrystalline cells but this does not indicate that monocrystalline cells do and also outcomes even more power than polycrystalline cells. Solar battery efficiency has something to do with the size of the cells and also every solar panel or cells have an effectiveness ranking based upon conventional examinations when they were made. This ranking is generally in portion as well as the typical worths range from 15% to 20%.

2.) Glass

The glass protects the PV cells while enabling optimum sunlight to travel through. These are usually made of anti-reflective products. Tempered glass is the selection of material nowadays also for unknown as well as brand-new producers although there are still those who utilize level plate glass on their solar panels. Safety glass are developed by chemical or thermal ways and also is lot of times stronger than plate glass making it extra pricey to create yet the rate of making them today is reasonable and affordable. Flat plate glass creates sharp and also long shards when broken instead of tempered glass which shatters safely in little items upon impact, that is why they also call it safety glass. It ought to be noted right here that most amorphous photovoltaic panels uses level plate glass due to the means the panel is built.

Safety glass is what makers make use of in mass producing their photovoltaic panels. In our Do It Yourself project, we suggest to make use of Plexiglas also called acrylic glass which is much safer than the routine normal glass from your local equipment store. It is a little bit costly than normal glass however is weather condition resistant as well as does not break easily. The Plexiglas can also be screwed or glued easily to the structure.

3.) Structure

A framework is normally made from anodized aluminum which gives structure and strength to the solar module. These light weight aluminum structures are also created to be suitable with the majority of solar mounting systems as well as basing tools for very easy as well as risk-free setup on a roof covering or on the ground.

The structure in a factory-built photovoltaic panel is usually the aluminum part where all four sides of the solar panel sheet are placed. Think about it as a skeletal rectangle-shaped framework. The photovoltaic panel sheet by the way is composed of the various other 4 parts and also are split as well as laminated in the adhering to order from top to bottom; the toughened up glass, top encapsulant, the solar batteries, bottom encapsulant, then the backsheet. In our Do It Yourself solar panel, we will certainly be using a wood framework and also the end-result would be something analogous to a picture frame where the picture is the solar cells glued to a non-conductive board, the glass for the Plexiglas top cover, and also the wood part as the frame and backsheet.

4.) Backsheet

The backsheet is the layer of plastic film on the back surface area of the module. This is the only layer shielding the module from dangerous DC voltage. The major function of the backsheet is to shield and also secure the handler from shock and also provide the most safe, efficient, and also reliable electrical conductivity possible.

The backsheet will certainly be a wood plywood where the frame will certainly be screwed on the top and also on the sides. It ought to be noted below that a perforated hardboard (Pegboard) will certainly be made use of to place as well as align the PV Cells and this Pegboard will certainly sit on top of the wood backsheet and also fitted inside the wooden frame.

5.) Junction Box

The junction box is where the incurable cords and also bypass diodes lie and also concealed. The incurable cables are essentially the positive as well as negative cables based on the collection links of the PV Cells and also can be linked to one more photovoltaic panel, a cost controller, a battery system, or to an inverter, relying on the system design. The bypass diode is a safety mechanism that protect against power from getting back to the photovoltaic panel when it is not producing electrical power as in case when it is night time.

There are junction boxes developed for factory-built solar panels that are now readily available to buy online specifically from China. If you are not pressed for time, you can buy online and also await the shipment otherwise you can simply purchase a regular electric junction box from your local equipment store. The objective of the junction box is to safeguard the terminals ( favorable and adverse terminals) from water, dirt, and various other components. This is also where both cables (red for positive and also black for negative) will be originating from. The other end of these 2 cables can additionally be safeguarded by utilizing a PV accessory called MC4 which can additionally be acquired on the internet together with the PV junction box.

6.) Encapsulant

Encapsulant sheets prevent water as well as dust from infiltrating the solar components as well as act as shock-absorbers that shield the PV cells. They have this adhesive bonding capacity to the glass, the PV cells, and the backsheet similar to a glue but more powerful. Encapsulants are usually constructed from Ethylene-Vinyl Acetate or EVA and also are used making use of lamination machines and processes. Photovoltaic panel makers make use of a vacuum cleaner and also a large stove to effectively seal and also treat the EVA sheet onto the photovoltaic panels. Most of us do not have the ability to do this yet lots of still have attempted and also failed while others had differing levels of success.

Encapsulants are slim plastic sheets that are usually laminated on the leading and bottom parts of the solar cell sheet. The bottom encapsulant is the layer in addition to the backsheet where the solar batteries are really put as well as supported.
