Devices those convert solar energy into electricity are known as solar panels. A single solar panel is a collection of solar cells largely spread on a surface and they work together to provide enough power to be useful. Solar Panels are also known as Photovoltaics which means, basically, “light-electricity.
Solar cells in solar panels are made of silicon, like semiconductors. They are constructed with a positive layer and a negative layer, which together create an electric field, just like in a battery.
These days solar panels for homes are extensively popular as they have specific advantages as an energy source. Once installed, its operation generates no pollution and no greenhouse gas emissions and the material used for making solar panels – silicon has large availability in the Earth’s crust.
With the rising prices and undeniable depletion of fossil fuels, people have switched to solar power for their needs as it is a renewable source of energy.
Some of the advantages of solar power are mentioned below.
- Renewable Energy Source
- Reduces Electricity Bills
- Diverse Applications
- Low Maintenance Costs
- Technology Development
Some facts about solar panels in Melbourne, Victoria
