Develop Solar Energy for Economic Growth
It is believed that in just six hours, world's Desert receive more energy from the Sun than human consume in a year. For example, take an area of the size of Indian state of reasonable size in the Sahara desert and fill it with solar panels and you could power the whole of India, rather some surplus may remain.
The move to clean renewable energy is very important when fighting climate change. By using natural resources such as the Sun, wind and tides, energy can be created without any pollution. Presently, we use lot of oil, Gas and coal to power our country, but there are several large solar projects such as in Africa, Europe etc. underway working to harness the power of the desert Sun.
The Sahara is the largest hot desert on Earth (some deserts are cold like Gobi desert in Asia) and can reach temperature of 50 Degree Centigrade.
There are few problems to solve first such as how to stop sand causing damage to the solar panels. Cleaning them daily uses up a lot of water - something that in not in desert. According to NASA estimates, each square meter receives, on average, between 2000 to 3000 kilowatt hours of solar energy per year. If all the sunlight hitting the desert converted into electricity, it would provide 7000 times more power than Europe's total energy demand.
Creation of Solar Energy
Solar panels, known as modules, contain photovoltaic cells made from silicon that transform incoming sunlight into electricity rather than heat. '' Photovoltaic'' means Electricity from Light - Photo = Light, Voltaic = Electricity. Solar photovoltaic cells consists of a positive and negative film of Silicon placed under a thin slice of glass. As the photons of the Sunlight beat down upon these cells, they knock the electrons off the silicon. The negatively - charged free electrons are preferentially attracted to one side of the silicon cell, which creates a electric voltage that can be collected and channeled. This current is gathered by wiring the individual solar panels together in series to form a solar photovoltaic array. Depending on the size of the installation, multiple strings
of solar P.V. array cables terminate in one electrical box, called a fused Combiner. Contained within the Combiner box are fuses designed to protect the individual module cables, as well as the connections that deliver power to the Inverter. The electricity produced at this stage is DC (Direct Current) and must be converted into AC ( alternating current) for use in offices and homes.
In a Solar electric system, that is also tied to the Utility Grid, the DC power from the solar array is converted into 120/240 volt AC power and fed directly into the Utility Power distribution system of the building. The power is net metered which means it reduces demand for power from the utility
when solar array is generating electricity thus lowering the utility bill. These Grid-tied systems automatically shut off if utility power goes offline, protecting workers from power being fed back
into the Grid during an outage.
Contributing clean, green power from solar energy system helps create jobs and is a great way to mitigate the pollution and other problems produced by electricity derived from fossil fuel. Solar powered electrical generating systems help reduce impact on environment and save money.
India's Position
Solar power in India is a fast developing industry. India's per capita energy consumption currently stands close to one-third of World's average. Solar and Wind were once considered costly source of
power, but are now much cheaper than the conventional form of energy. In order to become a world leader in Solar Power, India, cannot rely on importing solar equipment since its immediate necessity
is to develop entire value chain ecosystem to become competitive and head towards sustainable growth.
