Solar Power for Laptop and Notebook

This may seem unbelievable and impossible to do, but many computer geeks go "green" when they travel with a laptop in tow these days. If you're familiar with "extreme" or the distance calculation that does not seem too farfetched. Let us not forget that many professionals enjoy robust recreation, but I can not always leave the office behind.

The idea of solar energy for the calculation of distance is finally catching on. It works for everyone from the cross-country cyclist and camper weekend, the regular working stiffs who have the hard on the job.

Solar energy is not only a possibility, but might be a necessity for those who are remote. Solar panels are used to collect solar energy for direct use or storage in batteries to power later.


Here is how solar energy or photovoltaic energy is produced from the "How Stuff Works" site. If you are not an electrical engineer or scientist of some sort, do not be surprised if it makes light bulbs go off in your head. You can always come back and do further research on the Internet.

"The solar cells that you see on calculators and satellites are photovoltaic cells or modules (modules are simply a group of cells electrically connected and packaged in a box). Photovoltaics, as the word implies (photo = light, PV = electricity), convert sunlight directly into electricity. Once used almost exclusively in space, photovoltaics are becoming more in less exotic ways. They could even power your house. How do these devices ?

Photovoltaic (PV) are made of special materials called semiconductors such as silicon, which is currently the most commonly used. Basically, when light strikes the cell, a certain part of it is absorbed into the semiconductor material. This means that the light energy absorbed is transferred to the semiconductor. The energy of electrons striking loose, allowing them to circulate freely. PV cells also all have one or more electric fields that act in force electrons freed by light absorption to flow in a certain direction. This flow of electrons is a current, and by placing metal contacts on the top and bottom of the PV cell, we can learn that the current use outdoors. For example, the current can power a calculator. This current, with the voltage of the cell (which is the result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce. "

To continue, we will study the smallest handheld devices for cell phones and PDAs, all the way to powerful and fully autonomous remote commercial solar systems. Here are some links that describe the use of solar power for laptops and other wireless devices in the Do-It-Yourself perspective.
