what countries around the world use solar power to create electricity ( e.i. photovoltaic, concentrating solar power) please leave a web site. thanks! here’s section with some articles that could be helpful to you http://renewableenergyarticles.blogspot.com/2009/11/solar-energy.html

So if you had sunlight passing through the atmosphere at the equator on the a solar panel perpendicular to the direction of the light waves, how much energy in watts would it produce? I want the answer so I can … Continue reading →

I’ve been thinking about solar energy – photovoltaic panels – but I’m having doubt’s about how effecient it will be. (I live in Denmark – Scandinavia). Which photovoltaic cells can perform best under the weather-situation in Denmark, what is cheapest? … Continue reading →

I’m wondering how long a given solar panel needs to produce before it "makes up for" the energy used in it’s creation. How much energy does it take to make a 1 watt solar panel? I realize there are many … Continue reading →

The sun’s waves hit a photovoltaic cell and excites the electrons within layers of the cell. The excited electrons jump back and forth, creating electricity. This electricity is captured by wires running through the PV cells and sends the electricity … Continue reading →

ok so i have cardboard box 4 silver reflector cards 1 black panel base with cover 1 bottle connector 1 soft wax, adhesive tape 2 thermal indicator stickers (printed 70 degrees Celsius (158 degrees farenheit) and 40 degrees celsius (104 … Continue reading →

I’m looking for something besides the usual fuel cells, solar collectors, photovoltaic cells, waste-to-energy, hydro-electric, etc. I think I read somewhere about harnessing body heat for energy. Anyone know anything about that or can give me some links on that … Continue reading →

‘m looking for reliable info on the manufacturing of photovoltaic solar cells, especially costs (energy, materials, disposal, etc.). Thanks for your help, Check these reports:

Me and a good friend were thinking of possibly in a couple of years starting a small energy business, but were not sure if we should use solar thermal collectors, solar photovoltaic panels or wind turbines? im pretty sure wind … Continue reading →

hey guys i just needed a confirmation on my answers.. here is the questions. pls need help.. As regards solar energy, mirrors are used to a. generate steam b. shine light on passive solar collectors c. shine light on photovoltaic … Continue reading →
