What Are Solar Panels?

The sun is the primary supply of energy on Earth and sunlight may be transformed directly into electricity using photo voltaic panels. Electricity has grow to be indispensable in life. It powers the machines that most us use daily.

 

So, what are photo voltaic panels? What when you can create your personal?

 

In this article, we will show you a straightforward methodology of building your individual purposeful solar panel.

 

THE COMPONENTS

 

A photo voltaic panel is normally manufactured from six (6) components namely the PV (photovoltaic) cell or photo voltaic cell which generates the electrical energy, the glass which covers and protects the photo voltaic cells, the body which supplies rigidity, the backsheet where the photo voltaic cells are laid, the junction box the place the wirings are enclosed and linked, and the encapsulant which paneles solares serves as adhesives.

 

Since most individuals doesn’t have access to gear in manufacturing photo voltaic panels, it is very important note and understand these six elements to ensure that anybody to be able to plan the materials wanted to create a do-it-yourself or residence-made photo voltaic panel.

 

The supplies needed on learn how to make a photo voltaic panel must be available for buy locally or online and shouldn’t exceed the price of a model new photo voltaic panel or doesn’t take a very long time to build.

 

1.) PV Cell

 

The primary thing to consider when building your own solar panel is the photo voltaic cell.

 

Photovoltaic (PV) cell or photo voltaic cell converts visible light into electricity. One (1) solar cell however just isn’t sufficient to supply a usable quantity of electricity very like the microbot in Baymax (Hero 6) which solely turns into helpful when combined as a group. This primary unit generates a DC (direct present) voltage of 0.5 to 1 volt and though this is reasonable, the voltage continues to be too small for many applications. To produce a helpful DC voltage, the solar cells are connected in sequence after which encapsulated in modules making the solar panel. If one cell generates 0.5 volt and is related to another cell in series, those two cells ought to then be able to supply 1 volt and they can then be called a module. A typical module usually consists of 28 to 36 cells in series. A 28-cell module must be able to provide roughly 14 volts (28 x 0.5 = 14VDC) which is enough to charge a 12V battery or power 12V devices.

 

Connecting or more solar cells require that you’ve got a fundamental understanding of series and parallel connection which is similar to connecting batteries to make up a battery storage system.

 

There are most common photo voltaic cells that can be bought out there; a monocrystalline cell and a polycrystalline cell. These can have the same dimension, 156mm x 156mm, however the main distinction can be efficiency. You will need to buy additional cells to serve as backup in case you fail on a number of the cells i.e. bad solder, broken cell, scratched, etc.

 

Monocrystalline photo voltaic cells are often black and octagonal in shape. This type of solar cell is made of the highest and purest grade silicon which makes them expensive. However they are essentially the most environment friendly of all types of solar cells and are virtually always the selection of photo voltaic contractors when area is a vital factor to consider in achieving the power they need to attain based on their photo voltaic system design.

 

Polycrystalline PV Cells are characterised by their bluish shade and rectangular shape. These cells are manufactured in a much simpler process which lowers the purity of the silicon content material and also lowers the effectivity of the end product.

 

Generally, monocrystalline cells are more environment friendly than polycrystalline cells but this doesn’t mean that monocrystalline cells carry out and outputs more power than polycrystalline cells. Solar cell efficiency has something to do with the dimensions of the cells and each solar panel or cells have an efficiency rating based on normal tests once they were manufactured. This ranking is normally in proportion and the common values range from 15% to 20%.

 

2.) Glass

 

The glass protects the PV cells while permitting optimum sunlight to pass through. These are normally made of anti-reflective materials. Tempered glass is the selection of material nowadays even for unknown and new producers though there are still those that utilize flat plate glass on their photo voltaic panels. Tempered glass are created by chemical or thermal means and is many times stronger than plate glass making it more expensive to supply however the worth of manufacturing them at the moment is reasonable and value-effective. Flat plate glass creates sharp and lengthy shards when broken as opposed to tempered glass which shatters safely in small items upon impact, that’s the reason in addition they call it safety glass. It must be noted right here that the majority amorphous photo voltaic panels uses flat plate glass because of the way in which the panel is constructed.

 

Tempered glass is what manufacturers use in mass producing their solar panels. In our DIY project, we recommend to make use of Plexiglas also called acrylic glass which is safer than the regular regular glass from your local hardware store. It is a bit costly than common glass however is climate resistant and doesn’t break easily. The Plexiglas can also be screwed or glued easily to the frame.
