Solar Enrgy and What is Solar Power

Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP) Solar energy is energy generated from heat or light from the sun, which can be used to produce heat, light, hot water, electricity, and cooling in a wide range of applications. When we say that something from the solar panels, we mean that the energy it uses has been converted directly from solar energy or sunlight. Solar energy is often called "alternative energy" sources of energy to fossil fuels such as oil and coal.

History of photovoltaic technology

We used the Sun for drying clothes and food for thousands of years, but only recently have we been able to use it to produce electricity.

History of photovoltaic technology has more than a hundred years, but it was not until the mid-20th century that scientists at the Bell Telephone discovered that an element called silicon produced an electric charge when exposed to sunlight. However, the earliest solar batteries have been expensive and not very efficient, only a part of the conversion of sunlight into electricity. Today, solar panel technology has greatly improved efficiency.

What is solar energy supply, which makes it such an attractive source of energy?

Solar energy is completely free and inexhaustible source of fuel
• No fuel, waste or pollution is expelled in its use.
• In remote areas or small villages, solar energy can be a saving grace. Sometimes it is the only real way to produce energy in a place that is not capable of drawing energy from other sources.
• It can be used for low-power, as well as larger-from chargers, pocket calculators and solar garden lights to the air-conditioned vehicles and satellites.
Solar energy can be an integral part of any combination of clean, renewable energy to meet the country's electricity needs while reducing harmful greenhouse gas emissions.
