Solar energy refers to energy from the sun. The sun has produced energy for billions of years. It is the most important source of energy for life forms. It is a renewable source of energy unlike non- renewable sources such as fossil fuels. In 1839, Alexandre Edmond Becquerel discovered the photovoltaic effect—that is, the ability to create an electric current from the sun’s rays. Shortly after, Russell Ohl invented the first solar panel cell in 1941 and the first commercial panel was put out by Bell Laboratories in 1954. Some Important facts and Info On Solar Panels Fact 1: Solar energy is a completely free source of energy and it is found in abundance. Though the sun is 90 million miles from the earth, it takes less than 10 minutes for light to travel from that much of distance. Fact 2: Solar energy which comprises of radiant heat and light from the sun can be harnessed with some modern technology like photo-voltaic, solar heating, artificial photosynthesis, solar architecture and solar thermal electricity. Fact 3: The solar technology can be distinguished into active and passive. Photovoltaic panels and solar thermal collectors which harness solar energy are examples of active solar technology. Passive technology includes constructing rooms to improve air circulation, orienting space to favorably use sunlight. Fact 4: The earth gets 174 Petawatts of incoming solar radiation in the upper atmosphere. About 30% is reflected back to space and the rest is absorbed by oceans, clouds and land masses. Fact 5: The water cycle is an important result of solar insulation. The earth, oceans and atmosphere absorb solar radiation and their temperature rises. Warm air rises from the oceans causing convection. When this air rises to high altitudes, clouds are created by condensation of water vapor. These clouds cause rains that bring water back to the earth’s surface which completes the water cycle. Fact 6: Solar energy has also another use. By means of photosynthesis, solar energy is converted by green plants into chemical energy which creates the bio mass that makes up the fossil fuels. Fact 7: Horticulture and agriculture seek to make the maximum use of solar energy. These include techniques like timing of planting cycles and mixing of plant varieties. Green houses are also used to convert light into heat to promote year round cultivation of special crops. Fact 8: Solar powered hot water systems utilize solar energy to heat water. In certain areas, 60 to 70% of water used domestically for temperatures as high as 60 degree Celsius can be made available by solar heating. Fact 9: Solar chimneys are passive solar ventilation systems. Shafts connect the interior and exterior of the building. The functioning can be improved by glazing and using thermal mass materials. Fact 10: Solar energy can also be used for making potable, brackish or saline water. Without using electricity or chemicals, waste water can be treated. Creating salt from sea water is also one of the oldest uses of solar energy. Fact 11: Clothes can be dried in the sun using clothes lines, cloth racks etc. Fact 12: Food can be cooked, dried or pasteurized using solar energy. Fact 13: Solar power is the most exciting use of solar energy.
