Solar energy - Electricity Generation: Solar radiation may be converted directly into solar power (electricity) by solar cells, or photovoltaic cells. In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors.
Solar energy comes from the limitless power source that is the sun. It is a clean, inexpensive, renewable resource that can be harnessed virtually everywhere. Any point where sunlight hits the Earth's surface has the potential to generate solar power. Solar power is renewable by nature.
People now use many different technologies for collecting and converting solar radiation into useful heat energy for a variety of purposes. We use solar thermal energy systems to heat: Solar photovoltaic (PV) devices, or solar cells, convert sunlight directly into electricity.
The output of a solar power system is measured in watts. Solar energy—also known as solar power, solar generation, or solar radiation—is the most abundant, renewable source of energy. A renewable energy source is an energy source that can be regenerated.
Solar energy is an environmentally friendly energy source. Learn the advantages of solar power and how to incorporate solar generation into your everyday life.
