Solar energy refers to the use of energy from the sun to generate electricity or heat. The energy is captured through the use of solar panels, which convert sunlight into electrical energy through the use of photovoltaic (PV) cells. Solar energy is a renewable source of energy, which means that it can be used without depleting natural resources or harming the environment.
There are two main types of solar energy systems:
- Photovoltaic (PV) systems: PV systems are the most common type of solar energy system, and are used to generate electricity. PV systems consist of solar panels that are connected to an inverter, which converts the DC power generated by the panels into AC power that can be used to power homes, businesses, and other facilities.
- Solar thermal systems: Solar thermal systems are used to generate heat, and are often used for hot water heating or space heating. These systems consist of solar collectors, which absorb the heat from the sun and transfer it to a fluid, such as water or antifreeze, which is then circulated to provide heat.
Solar energy has many advantages over traditional sources of energy. It is a renewable source of energy, which means that it can be used without depleting natural resources or harming the environment. Solar energy is also cost-effective, as the cost of solar panels has decreased significantly in recent years. In addition, solar energy can be used in remote areas where it is difficult or impossible to access traditional sources of energy.
