More commonly known as solar power systems, photovoltaic systems convert sunlight directly into electricity. Photovoltaic got its name from the process of turning light or photons into electricity or voltage and is called the PV effect.
Some Facts About PV
- A single photovoltaic device is called a cell. A single cell typically produces 1 to 2 watts of power.
- Cells are connected together to form panels and generate greater power.
- Solar panels can be used individually or can be connected to from arrays.
- A complete photovoltaic system is composed of one or more arrays that are connected to the electrical grid.
- In the USA, the largest PV system is found in California and produces 579 megawatts of electricity that is distributed to consumers.
- A solar farm in Cadiz in the Philippines is believed to be the largest in Southeast Asia, generating 135 megawatts.
How do PV Systems Work?
A photovoltaic or solar cell is a sandwich of silicon materials which are conductors. It generates electricity by using sunlight to make electrons jump between the two silicon. Simply put:
- When sunlight shines on the cell, it is absorbed by the upper surface.
- The light particles then carry their energy down through the cell.
- The energy of the photons (light particles) is transferred to electrons in the lower surface of the cell.
- The electrons use the energy to jump out of the cell into the circuit as electricity.
PV Systems in the Philippines
The photovoltaic market in the Philippines may still be small but solar power companies, like SOLREV Energy, are making inroads all over the country. The future of solar energy here is bright, especially since this island nation is always sun-drenched and electricity costs are expensive.
The success of photovoltaic systems comes from a combination of government efforts and power companies’ support. It is very nice to see the government incorporating solar power in government infrastructures. The solar powered streetlights making the streets of metro cities bright, for example.
The advantages of using this renewable and sustainable energy source are getting recognized by everyone. Businesses have started using solar power in their factories and establishments. Filipino homes are also joining the increasing population using photovoltaic systems.
Using energy from the sun can not only decrease your expenses in the long run but can also benefit the environment. SOLREV Energy, a provider of solar panels and equipment, can give you more information on this and educate you even more.
