The boundless of potential of solar energy to revolutionize the way we live should not be underestimated. The best way to get a real understanding of its promise is to make a focused study of the topic and learn everything you can about solar energy. The article below provides you with a wonderful jumping off point.
If you’re thinking about installing solar panels to generate your own electricity, make sure that the roof you’ll be installing them on gets plenty of good sunlight. Good sunlight occurs between 9am and 3pm. You’ll generate the most electricity if your roof receives full, exposed sunlight between those hours every day.
If you decide to put solar energy panels on your home, remember to keep them clean. Your solar panels must reflect the sun’s rays in order to store the sun’s energy for use in your home or business. If they are dirty, they can not effectively do this. By keeping them clean, you will get the most bang for your buck!
Position solar panels on the east or west side of your home or business. Since the sun travels from east to west throughout the day, placing solar panels on areas of your roof that face north or south is a waste. You’ll get much better energy returns by following the same path as the sun.
Fossil fuels that are used around the world do not help our environment. In fact, the cause a great deal of damage to the world we live on. Solar energy will provide us with the power we need without causing any damage to our earth. There will be no more gases, carcinogens or even carbon dioxide produced by solar energy.
There really is no limit when it comes to the power of solar energy to alter our daily lives. In order to truly grasp what solar power has to offer, you need to acquire as much knowledge as possible from the voluminous sources available on the subject. The article above serves as a handy framework for doing just that.

Manila, Philippines – Sitero Francisco Memorial National high School in Barangay Ugong, Valenzuela City had just installed a 1Kw photovoltaic solar panel capable of powering nine-classroom in a building. This will be the first solar powered school in the country.
This projects was headed by Cesar Villareal (School Principal) and Jamesone Tan (Science Department Head). By searching for a good sponsor, Tan found Wanxiang Americ Corp, Universal Solar (Wanxiang Energy Division) and funded the project through the Foundation for Environmental Education (FEE). A six solar panels, where shipped from Illinois, USA by Wanxiang America. Valenzuela’s City government handled the cargo and installations. The solar panels that where shipped cost around 500K.
These solar panel is capable of generating 1Kw to 5Kw of electricity depends on the intensity of the sunlight. The usual setup for a solar power was applied here, means that the solar panel’s cells collect sunlight and convert them to electricity and distribute them to the class room, some excess energy that where gathered where stored to series of batteries to be used at night .
“Once operational, the solar project will help students become more aware of their energy needs, the science behind it and other vital issues on energy utilization,” Villareal said.

Massachusetts Institute of Technology (MIT) scientist had just made another breakthrough in the solar power technology, they had successfully printed a solar cells on a paper. Well its seems that nano technology is beginning to grow. In a press conference last Tuesday as mentioned in the CNET news, Susan Hockfield, MIT’s president, and Paolo Scaroni, CEO of Italian oil company Eni, officially Lunched the Eni-MIT Solar Frontiers Research Center. The research center had been investing millions of dollars and also receiving funding from the National Science Foundation as said by Vladimir Bulovic, the center’s director.

The MIT researchers are using a carbon-based dye materials and the cells had a 1.5 to 2 percent accuracy in converting sunlight to energy. The research was headed by MIT professor Karen Gleason and has submitted the paper for scientific review and not had been published yet.
Well this kind of breakthrough in the solar technology could be a better help for us when published. Its could be cheaper than the conventional solar panel and lighter. I see many application could benefits this especially countries that in need of alternative power source.

Solar panel, also known as photovoltaic module or photovoltaic panel is a device that collect light energy and convert it to electricity. It uses photovoltaic cells most commonly known as the solar cells. its development was started by a french physicist Antoine-César Bacquerel in his 1839 research. By observing its effect while doing an experement with the solid electrode dipped in an electrolyte solution(the one used in a battery) he notice a voltage was developed when the electrode is exposed to sun light.
Around the 40’s solar cells, however, had a one percent energy conversion efficiency. It was then develop in the 50’s by three American researchers, Daryl Chapin, Gerald Pearson and Calvin Fuler(creator of the first solar panel). They design a silicon base solar cell and manage to increase its conversion efficiency up to seven percent. In their research, by exposing some strips of silicon solar cell to sun light, it capture the free electrons and convert it to electrical current. A year after, Bell Laboratories funded the research and manufacture the first (prototype) solar battery. It was comercialized
Now, many company and institution are developing the use of solar panel like in toys, small electronic gadgets, alternative power source for homes, to power a space station, solar powered supply for laptop computer and they are now developing the use of it for cars and other kinds of transportation. There are many university that are now competing in developing a solar powered rasing car and based on my research a one was held last October 7, 2007 in Australia it was the World Solar Challenge. A technology like this could give a lot of contribution in our future needs.
