Converts Sunlight "DIY" Solar Panel and Wind Power reviewed

Question by : Building solar panel what is the most effective one and chippest?
Hi , I am from Argentina.
The prostitue we have as a president dediced to get electricity bill 400 % higher.
So, what is a good way to start getting everything with solar energy, I have seem somebody doing a solar panel with black painted cans of soda. What other alternatives do I have.
Thanks

Javier, those black painted cans were most likely for a passive collector to get heat from the sun. This is one way of using solar energy. This leads into a vast array of applications. There are units that reflect the sun light into a narrow beam that is a few millimeters thick, but is as long as the reflector is with the light focused on a pipe that carries water, or some other working fluid to where the heated fluid is to be used. If done properly, and safely, you could make water into steam to drive a turbine to make electricity. That, however, requires tracking systems to keep the reflectors pointed at the sun. The best way, least expensive of any, but still will be expensive to set up, is photo=voltiac panels. These absorb sunlight and turn it into electricity. These should be used to charge batteries for the time when the sun is not out, or at night. Within practical limits, your battery bank can not be to big. Trying to make your own photo-voltiac panels is out of the question. Those silican wafers from which the electricity producing panels are made require special manufacturing processes, which unless you are extremely rich, are beyond your means. You will need to buy such panels, and yes, they are expensive. That is out weighed by how long they will last, which barring physical damage, or a high enough reverse voltage applied to them, those panels should last for 20 or more years. Good luck with what you want to do. Begin small and work up to a large system, as large as you need it to be.
