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.

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.
