Photovoltaic Solar Panels Made Easy - How They Work And How They Are Made

Creating photovoltaic solar panels is by no means an easy task, even the technically minded may find it a challenging feat to assemble from scratch.  It is a relatively new innovation in harvesting the Sun’s energy and has only been around for around 60 years. So there is not that much information on the subject and modification and improvement of the technology is an ever constant. With this said there are two ways that the average person can create photovoltaic solar panels. These methods can be termed semi-DIY and full-DIY. This article will cover how these processes work and how you can build photovoltaic solar panels.

However before we get into the details, lets discuss how photovoltaic (PV) solar panels work.

Although there may be a collection of other solar devices out on the market that have the ability to heat water for example, those particular mechanisms are unable to produce electricity. On the other hand the photovoltaic solar panels talked about in this particular case are those that have the capability to produce electricity or energy from sunlight. Most people can intuitively understand how heat from the Sun can be utilized but it’s not as clear how light can be used.

In professional solar panels, the material used in the PV cell reacts with sunlight of a certain frequency. This reaction ‘throws loose’ an electron. When many PV cells are connected from a negative to positive terminal, the negatively charged electrons flow to the positive terminal. This is an electrical current. This can be stored and used to power appliances or anything else that is powered by electricity.

There are basically two ways to approach this specific project.  People who intend to install photovoltaic solar panels in their homes can either choose between semi-DIY or getting it professionally installed. A full-DIY solution used copper to produce photovoltaic cells and is really a funky project to undertake but is not really a practical option to supply electricity to the home.

Semi do-it-yourself will require the purchase of solar panel kits and then assembling their parts. In most cases, these kits aren’t overly complicated and come with complete easy-to-follow step-by-step instructions.  These are recommended for those with moderate skills when it comes to handy-man work.  On the other hand, the full do-it-yourself photovoltaic solar panels are a little more complicated.  Advanced skills and a whole lot of patience are required to assemble a solar panel from scratch.

Semi Do-It-Yourself

There are a lot of places one can purchase a photovoltaic solar panels kit from. Some major hardware stores sell these types of kits but another option would be to purchase one online as the variety and model types are endless.  Most kits will come with mounting devices, installing hardware, wiring kits, and the photovoltaic cells themselves.  They should also come with either a set of video or print instructions. Some localities require that only licensed workers perform these types of jobs so it may be best to check first. You can also get guides or manuals that show you how to make PV cells but leave the sourcing of the materials up to you. The advantage of these guides over complete kits is that they are cheaper and generally suggest cheaper alternatives to find the materials than an all in one kit.

Full Do-It-Yourself

Creating photovoltaic solar panels from scratch will obviously require more work.  In a nutshell here are the few basic steps required to create a fully functional solar panel.

Firstly, you will need to obtain raw copper sheeting and then heat it for around half an hour.  This is to form a layer of copper oxide on the sheet’s surface.  After it cools, it should be kept along with non-oxidized copper sheeting.  A solution of salt water must also be added and the sheeting should be submerged in a split-proof glass panel.  The wiring would then need to be fixed and the mounting jacks put in place.  A normal household will need a number of these panels to ensure that enough energy is produced. These of course are just the beginnings of constructing photovoltaic solar panels.

More people are thinking about putting solar panels into their homes. This is becoming easier with the introduction of DIY kits or DIY manuals. There are also incentives to get professionally made panels. It seems pretty clear that this is a energy source that will be used by more and more households as we go forward.
