Project build a solar panel step by step guide to building a solar panel with complete illustrations 4 other gases in the atmosphere


The purpose of this project is to demonstrate how to build a solar panel from individual components (not to mention that I was curious). With the correct components, the cost of constructing a solar panel with longevity against environmental degredation can cost up to 30% less than commercial solar panels of the same Watt rating (not to mention that what you create, based on your assessment of the environment a solar panel would be used in, could actually be more resiliant than a "cookie cutter" manufactured solar panel).

A solar cell’s purpose is to generate electricity through the release of electrons from a material that is bombarded by electromagnetic radiation or photons. Most crystalline solar cells are sensitive to visible radiation from 400 – 700 nanometers, which correspond to 3.1 – 1.8 electron volts, of the visible region as shown by ACEPT W3 Group (1999) and also into the near infrared spectrum. As the wavelength of the electromagnetic radiation increases, the amount of electron volts decreases. This means that infrared radiation has less electron volts than the visible spectrum of light (because it has a larger wavelength than visible light) and ultraviolet and gamma radiation has more electron volts than both the visible spectrum of light and infrared radiation (because they have a smaller wavelength than both infrared and visible light). e gaskell north and south Abramowitz, M., Davidson, M., Neaves, S. (2003) wrote that all forms of electromagnetic radiation originate from the atom which contain orbiting electrons around its nucleus. When those electrons absorb more external energy than they can contain in order to be stable, the extra energy is released in the form of an electromagnetic wave. That electromagnetic wave contains a magnetic field and an electric field, one offset by ninety degrees to the other along the propagation plane.

Noted by Seale, E. (2003) the first silicon solar cell was developed by Russel Ohl in 1941, was similar to a photodiode with a large light-sensitive area. Aldous, S. (2007) wrote that pure silicon, the main component of silicon solar cells, is a poor conductor of electricity in itself. In fact, the silicon atom is missing four electrons in its outer shell. A phosphorous atom, on the other hand, contains five electrons in its outer shell meaning that it can bond with silicon atoms and since it has an extra electron which can be displaced by electromagnetic radiation, energy is created in the process. However, capturing this energy is not possible without creating an electric field. This is done by introducing impurities in the silicon material. As previously mentioned, silicon mixed with phosphorous creates an N-Type semiconductor; N-Type or negative because the phosphorous contains free electrons. Silicon mixed with boron atoms (which contain only three electrons in its outer shell) represents an absence of electrons and becomes the P-Type semiconductor; P-Type or positive. At the plane of where the N-Type and P-Type are joined is where the electric field is generated and the solar cell reaches electrical neutrality. The introduction of photons (electromagnetic radiation) on the N-Type semiconductor (silicon and phosphorous) frees electrons that try to travel to the P-Type semiconductor (silicon and boron) where the photon would remove an electron. electricity rate per kwh philippines The presence of the magnetic field between the two layers prevents this travel from occurring to a degree directly from the N-Type semiconductor to the P-Type semiconductor. This means that when we connect a load to the P and N semiconductors, we observe current (from electron flow) and voltage (from the magnetic field) as the free electrons move from one semiconductor to the other through the load.

A solar cell, in itself, is of little value in our energy consumptive world. Only when solar cells are joined together into arrays or panels do we commonly see their true benefit in delivering mass volumes of energy. Depending on what requires power determines the number of solar panels required. For instance, if you were interested in powering your entire house you would undoubtedly need a lot of solar panels; there is an online calculator that you can use to get an idea of how many solar panels and other components you may need, which you can find at the solar panel battery calculator page.

Monocrystalline 6 inch (156mm) solar cell rated at .5VDC, 6 Amp Peak. You can get new 156mm solar cells in bulk from; however, if you are interested in a set of 36 smaller solar cells, you can get a set from You could also try to locate solar cells from a seller at or

Personally I would not buy solar cell fragments or "grab bags" of broken solar cells as you could easily spend hundreds of hours piecing together enough fragments to come up with 100 Watts of power (not to mention that resistance increases with the more wire to solar cell connections you make; resistance restricts the flow of electricity and generates thermal energy or "heat"). If that’s what you’ve got to work with, hey, that’s okay.

One of the big reasons more and more people are adopting solar power is to "go green" or reduce their carbon footprint since studies have been conducted revealing that buildings, houses (or residences) contribute something in the neighborhood of 20,000 pounds of carbon dioxide per year each (you may not have a carbon dioxide generator where you live, but if you consume electricity, natural gas, water, sewer service and so on then those "services" create carbon dioxide as a byproduct of what you are consuming). Others may be adopting solar power because they have no choice (maybe you live on an island, for instance, where there is no power).

Regardless of the reason for getting or making your own solar panels, determine what they will be used for. If you want to provide power for an electric fence, you may only need one 100 Watt solar panel so your investment will be quite low. On the other hand, if you are trying to power your residence with solar panels, you will need more than 100 Watts. electricity allergy What I have found is that for a 1000 square foot residence, you would need roughly eight 100 Watt solar panels per person (this judgement is by no means scientific but a starting ballpark number to look into). To get a more precise reading on the amount of solar panels you would need, use this solar power calculator. Here’s a quick glimpse of what to expect, in terms of power needs, if you use 350kwh of power in a month…you’ll need 2700 Watts of power (27 – 100 Watt solar panels) and roughly 16 – 12VDC, 100Ah deep cycle batteries (batteries incase you plan to use electricity when the sun is not shining).

As you can see, defining the purpose of the solar panels and doing a little research may help a lot in getting an approximation of what it will cost. But, going back to the purpose of this project (to create a solar panel from component parts) can shave upwards of 30% of the cost of the solar panels. But, be ready to put in some work to create a solar panel. It does take time (90% of that time spent soldering like there is no tomorrow). It took me about 12 hours to tin wire, solder that to the solar cells, and then solder the solar cells together…for a single 100 Watt solar panel.

The type of solar cell that I will be using for this guide is the blemished (or class ‘b’) six inch diameter, Siemen’s (now Shell) PowerMax monocrystalline solar cell…you can get class ‘a’ cells but they are more expensive. A perfect operating solar cell (class ‘a’) will normally generate a maximum of approximately .55 VDC, 5.6 Amps and 3 Watts of power (a watt is calculated by multiplying voltage and amperage together). Just as a side note, one horsepower is equal to just over 700 Watts.

• While it is not required, it is recommended that you sandwich the soldered solar cells inside of a protective thermoplastic material such as ethylene vinyl acetate (EVA) sheet or UV resistant Surlyn sheet. Over time, if there is oxygen or other contaminants inside the solar panel, your solar cells will degrade prematurely. If you have one of those types of sheet, place the sheet over the solar cells you’ve just soldered together and use the heat gun on the sheet so that it adheres to the solar cells.

• You will notice that I have placed the solar cells on top of white paper and then soldered them together in advance of heating EVA sheet onto them. The reason for this is that the EVA sheet is a very adhesive material when heated (it also becomes approximately 100% transparent after heating). When flipping over the solar panel in a cardboard frame (so that the other side can have EVA sheet applied to it), the paper can be easily removed; without the paper between the solar panel and the cardboard it would be necessary to peel the inverted EVA sheet and solar panel from the rigid cardboard causing damage to individual solar cells.

• Take the 48 x 48 x 1/8 inch Acrylite UV stabilized transparent sheet and, using a cutting tool, cut it down to a 38 5/16 x 38 5/16 x 3/16 inch sheet. Place glue along the top of the four acrylic bars which were glued to the ABS white sheet. Place glue on top of each of the 1 x 1/4 x 1/4 inch blocks. Line up the Acrylite sheet with the edges of the four acrylic bars and place it firmly on top. Allow the glue to dry.

Congratulations, one solar panel has been created! The next section is here in the event that you want to protect your solar panel from reverse current. Current flowing into a solar panel will damage the solar cells and make them incapable of generating electricity (this typically can happen when you have the solar panel connected directly to a battery; if you have a charge controller, the controller will prevent this from happening). Assuming you don’t have a charge controller, you’ll need to add a rectifier diode to one of the wires coming out of your solar panel to block reverse current. This section will focus on adding the rectifier diode to the back of the solar panel.
