Project Build A Solar Panel: Step by step guide to building a solar panel with complete illustrations. Introduction 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).
How I built an electricity producing Solar Panel. Several years ago I bought some remote property in Arizona.
I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. In my attempt to escape city slicker yuppies (you know the kind, the ones that like to blab loudly on their cell phone while they work on some business administration degree in a cyber cafe somewhere in Trendyland.) and their light pollution, I found a great piece of remote property. The problem is, it's so remote that there is no electric service available. That's not really a problem. No electricity equals no light pollution. Homemade 63 Watt Solar Panel. Hybrid solar panel (photovoltaic and thermal)
I am not going to repeat all the details on how to build a solar panel, there are plenty of other instructables for this (search tool is your friend!).
I will give some basics, though... and then focus more on the "hybrid" nature of my panel (PV + thermal). General characteristics: - about 0.5 m^2 area, at a maximum of 1 kW/m^2 of irradiation and 12% efficiency this should produce UP TO 60 W of electrical power. (at the same time this means that about 440 W of thermal power could potentially be harnessed!).
Materials: - 36 cells, 3"x6". SOLAR PANEL DIY MAKE YOUR OWN SOLAR PANEL BUILD SOLAR PANELS. Build your own solar-powered water pumping station by Jeffrey Yago, P.E., CEM Issue #91. In the last issue, there was an excellent article by Dorothy Ainsworth on water pumping using mechanical windmills.
In this issue I will address another form of "free" water pumping. There are many remote applications where a solar-powered water pump is more cost effective than installing a conventional grid-connected AC pump. I recently designed a solar-powered pumping system for a local farmer wanting to pump water from a lake up to a watering trough for cattle in a distant fenced field. We have also designed larger systems to pump directly from drilled wells up to elevated storage tanks, which provide gravity-fed water back down to remote ranch buildings. Basic system description These solar applications made economic sense because the location was too remote to run a long power line. By adding a storage tank and increasing the size of the pumping system, excess pumped water can be stored, which can continue to supply water during the night or when it's cloudy and the pump is off.

I am an astronomer and wanted a place to practice my hobby far away from the terrible light pollution found near cities of any real size. I found a great piece of property. The problem is, it's so remote that there is no electric service available. That's not really a problem. No electricity equals no light pollution. One thing I noticed right away about my property is that most of the time, the wind is blowing. More details on this project and my other alternative energy projects including my home-built solar panels, and my home-built biomass gasifier can be found on my web site.

Bicycle Pedal Power Generator FAQ Frequently Asked Questions. Magnet DIY Energy. How to Produce Power With Magnets. Electromagnetic induction. Electromagnetic induction is the production of a potential difference (voltage) across a conductor when it is exposed to a varying magnetic field.
It is described mathematically by Faraday's law of induction, named after Michael Faraday who is generally credited with the discovery of induction in 1831. History A diagram of Faraday's iron ring apparatus. Change in the magnetic flux of the left coil induces a current in the right coil. How to Build a Super Magnet. Where Can I Buy Strong Magnets? How to Build Your Own Uninterruptible Power Supply. Edit Article Edited by Evildave, Brandywine, Jonathan E., MBD123 and 15 others In the event of extended blackout, you may have critical systems (such as computer or medical equipment) that must remain running no matter what.
This guide will yield one scalable uninterrupted power supply system. You may extend it with power generation, or solar/wind/etc. as you see fit. Alternator. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines.
An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators. History Alternating current generating systems were known in simple forms from the discovery of the magnetic induction of electric current in the 1830s. The early machines were developed by pioneers such as Michael Faraday and Hippolyte Pixii. Radial Air core alternator. Radial Air core alternator Fun! These are simple radial air core alternators that anyone with a drill and jig saw can build. Below are the basic parts for a single magnet 3 phase alternator... 2 plastic triangles sized to match the width of the magnet your using, 1 magnet, some small wooden dowl, 2 1/4" round steel stock ( cut bolts work well ), and some 1/4" bar stock that closely matches the thickness and width of the magnet your using.
Also, some copper magnet wire for the coils. Below shows the basic frame assembled... Next you'll wind 3 coils that will fit around the frame... I used 100 turns of #28 wire as an experiment and it worked pretty well but you can adjust the amount of turns you want based on the voltage you need. Lay the 3 coils over the triangles and tape the coils together. How to Design Your Own Homemade DC to AC Inverter. How to make your own 400 Watts DC to AC inverter from an old UPS. Transformer. A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. Electromagnetic induction produces an electromotive force across a conductor which is exposed to time varying magnetic fields. Commonly, transformers are used to increase or decrease the voltages of alternating current in electric power applications.
Since the invention of the first constant potential transformer in 1885, transformers have become essential for the transmission, distribution, and utilization of alternating current electrical energy. A wide range of transformer designs are encountered in electronic and electric power applications. Transformers range in size from RF transformers less than a cubic centimeter in volume to units interconnecting the power grid weighing hundreds of tons.
