Q:How does solar panel help/affect the economy?
sounds like a homework essay question to me
Q:What is the working principle of solar panels?
Based on the above considerations, silicon is the most ideal solar cell materials, which is the main reason for solar cells to silicon-based. But with the continuous development of new materials and related technology development, to other village-based solar cells are increasingly showing attractive prospects.
Q:Where can i buy mini (v - 2v) solar panels?
Radio Shack.
Q:How to prevent shorting out solar panel?
Just cover the panel and cut the wire the voltage will be so low it would be like shorting out a battery
Q:Why are solar panels so expensive?
They are made of costly materials and require expensive manufacturing processes. The market has been limited because people are not catching on very well to the new idea. The more we buy and use solar panels, the more the price will come down.
Q:How do you store energy using a solar panel?
probably a deep discharge lead calcium batteries, with a switching regulator cycloconverter or cycloinverter output to match the current and voltage requirements of the operated device.
Q:DIY kit for solar panel?
Build okorder.com
Q:solar panels in space?
You do realize that the sun is 50 million km away don't you?
Q:can solar panels be refurbished?
Yes, okorder.com/... This is a link that might help you more! You can explore the website on every subject though, to ensure you get the best information possible! Hope this helps! Kintalia
Q:Were solar panels made by copying how plants collect sunlight?
Solar panels were not made to copy leaves. Leaves have molecules that become excited when they are hit by light. They store this energy in ADP molecules and ATP molecules. This works great for biological processes, but until we learn how to use Adenosine Di/Triphosphate to transport energy, we are better off sticking with our solar panels. They produce electricity, which we know how to use.
