I was thinking of building my own solarpannels. How ever there are a lot of guides out there but they all cost money. I found a site pretending they where testing these guides but i could find an actual review ( http://www.selfmade-solarpanels.com ) Does anyone know a site where you can review the best instructions for building your own solarpannel ?
I recommend building your own panel only for the fun of it, not to save money. A homemade panel will cost more per kWh for electricity, because you will not be allowed to connect it to the grid, and therefore must build a standalone system with a battery or batteries.
The best instructions are free. This person provides them http://www.mdpub.com/solar/index.html . Also, see http://www.instructables.com/solar/ for both electric and heating panel projects.
Before spending money on plans from the web, I suggest reading this critique: http://www.nlcpr.com/Deceptions6.php

Since it is a fact that energy cannot die, just change form. Was this universe just created from a previous 1?
Since everything that exists must die, including our sun and solar system and galaxies etc. Then it would make sense that the universe will also die, and a new one will form?
Yes! I don’t often hear the right answer to "Where did the universe come from?"
Because energy becomes matter, and matter becomes energy, it stands to reason that "existence" of matter and energy is the default position of the universe, not "non-existence" as is implied in the question "Why does something exist instead of nothing?"
"Existence is a self-sufficient primary. It is not a product of a supernatural dimension, or of anything else. There is nothing antecedent to existence, nothing apart from it—and no alternative to it. Existence exists—and only existence exists. Its existence and its nature are irreducible and unalterable."

1. Solar Energy Concept: To some this idea may seem morose or even silly, however I believe an engineer would appreciate its value as would anyone who had the good sense to recognize a free multi-billion dollar concept. The idea is to replace the headstones in cemeteries with solar panels that have been etched with the deceased’s information, in any participating cemetery. The panel would be the length and width of the grave. At the base of the grave you would have a small placard. The land that the solar panel is placed on is effectively free, since the plot has been purchased for the deceased. The cost of the panel is effectively free, since it’s cost has been subsidized by switching the headstone for the panel.
Most cemeteries are located close to population centers. This one fact alone would allow real gains in actual recoverable energy by reducing line load losses that prohibit solar energy from obtaining a foothold in communities. The panels initial cost would be offset by the savings in not having to purchase the head stone. ( A rock produces no energy! ) The family of the deceased could be rewarded with an annuity that would help recoup burial cost in part and maybe in full! The solar panels would be clean, quiet, portable and easily upgradeable. The panels could be combined with any other energy sink a particular company might choose (fuel cell, flywheel, compressed air, geothermal storage, etc.). Greater return on equity for the cemetery, less green house gases, greater energy security for America and the world, a more robust and distributed energy source, increased productivity, more jobs and reduced or eliminated cost to the bereaved. The potential gains worldwide are enormous.
I wish you and yours good fortune in all endeavors,
Nice Idea by the way. Great Thinking
I mean what are the material needed to build solar energy for small device from 50mn volts to 24 volts
I may need more info on your Question, I think i can answer if i have more info!!
i have a diy solar panel E-book that may help that we put together its all free
this is the link

If you need more help, you can e-mail me i will try to help
thanks, David
On a clear day the energy of the sun that reaches the surface of the earth is about 1000 watts per square meter, or about 100 watts per square foot.
At best commercially available solar panels can only harvest about 20% of that.
Even still, that is more than most plants capture.
