Currently humans have to think to use alternative energy , such as solar power , wind power, biomass power, geothermal power, and other reserves as the depletion of natural resources, especially petroleum . The one that is now so much choice is solar power .

Since the last few decades, solar energy has been used in various countries. If properly exploited, solar energy predicted to provide the needs of the world’s energy consumption. Solar energy has its advantages, which can be used free of nature, as well as CO2-free making it environmentally friendly. With a tropical climate conditions sunlight throughout the year, Indonesia also has the potential to generate significant solar energy.

Solar cell or photovoltaic cell (solar cell), is a semiconductor device that is capable of converting sunlight into electrical energy. This transformation is called the photovoltaic effect. Solar power generation is competitive with conventional methods because it has aged long enough in use, no fuel needed, lower operational costs and quick in installation. If you assume, the cost of solar power will be quite low after depreciation. Hiroshi Morimoto explains, Group General Manager, Solar System Development Group Sharp Corporation Japan. “The use of photovoltaic modules extensively, can prevent climate change caused by global warming” said Hiroshi.

How Solar Cell Works.
Hiroshi said, the workings of solar power generation system, using a grid-connected photovoltaic solar cell panels. Module photovoltaic solar cells convert solar energy into DC electrical current. DC electric current generated will be channeled through an inverter (power regulator) which converts it into AC power, which will also automatically set up the whole system.

AC power will be distributed through the indoor distribution panels that will generate electricity as needed electronic equipment (televisions, radios, air conditioning, etc.). Large and the cost of electricity consumption used to be measured by Watt – Hour Meters.

Advantages of Solar Cells.
According to Hiroshi, the use of photovoltaics has several advantages when compared with other power plants, namely :
• clean and pollution free
• operates without any parts that need to be assembled.
• generate electricity without noise.
• requires almost no maintenance.
• electricity generated can be used for any purpose , anywhere , does not need big investment or security checks such as the nuclear industry.
• does not require the cost of transportation such as oil , coal , uranium and plutonium.
• durable and long lasting ( can reach 25 years ) .
