How does your energy source create electricity?
1. Photovoltaic (PV devices) or “solar cells” change sunlight directly into electricity. PV cells are grouped into panels that can be used in a wide range of applications from singe small cells that charge just calculator and watch batteries, to systems that power homes, to large power plants that cover numerous acres.

What is its potential?
Because convenient and affordable energy can help a household’s productivity and income potential, its availability can help families and communities break free of poverty.

How much electricity does it use?

This energy is usually calculated in what is called “kilowatt hours” (kWh) or 1,000 W, which equals to the amount of electricity needed to light up a 100 W light bulb for 10 hours.

This was originally developed in order to provide electricity for satellites, but these days many of us own calculators powered by solar cells.

Interesting facts (these aren't ...view middle of the document...

If we covered a small fraction of the Sahara desert with photovoltaic cells, we could generate all the world’s electricity requirements.
All TV and communications satellites are powered by solar energy using photovoltaic cells.
Solar energy is a renewable resource. Although we cannot utilize the power of the sun at night or on stormy, cloudy days, etc., we can count on the sun being there the next day, ready to give us more energy and light. As long as we have the sun, we can have solar energy (and on the day that we no longer have the sun, you can believe that we will no longer have ourselves, either).

of course since the philippines is sunny and hot as hell, this won't really be a problem but then again we have typhoons.

Solar cells are totally silent. They can extract energy from the sun without making a sound. Now imagine the noise that the giant machines used to drill for and pump oil make.

Solar energy is non-polluting. Of all advantages of solar energy over that of oil, this is, perhaps, the most important. The burning of oil releases carbon dioxide and other greenhouse gases and carcinogens into the air.

it might not be a problem about the global warming and co2 thing but carcinogens are bad!

Solar cells require very little maintenance and last a long time

Although solar panels or solar lights, etc., may be expensive to buy at the onset, you can save money in the long run. After all, you do not have to pay for energy from the sun. On the other hand, all of us are aware of the rising cost of oil.

Solar powered lights and other solar powered products are also very easy to install. You do not even need to worry about wires

Disadvantages:
1:One of the main disadvantages is the initial cost of the equipment used to harness the suns energy. Solar energy technologies still remain a costly alternative to the use of readily available fossil fuel technologies. As the price of solar panels decreases, we are likely to see an increase in the use of solar cells to generate electricity.

2:A solar energy installation requires a large area for the system to be efficient in providing a source of electricity. This may be a disadvantage in areas where space is short, or expensive (such as inner cities).

Solar power is also difficult and expensive to store. Another bad thing is that silicon the material that solar cells are made of can be hard to find. Solar energy is a good alternative energy for fossil fuels that can create electricity without any sounds and it is an ecofriendly energy source because it doesn’t emit gases that can harm our ozone layer. Solar energy is not as much danger as electricity, you can use solar energy as more as you want because it’s free and renewable.
