Exactly what is Solar Energy?
Solar energy refers to energy from the sun. Solar energy innovations use the sun’s energy to light houses, produce hot water, heat houses and electrical power.
The major advantage of solar energy is that it does not produce any toxins and is among the cleanest source of energy. It is a renewable source of energy, needs low maintenance and are simple to set up. The only limitation that solar energy possess is that it can not be used in the evening and quantity of sunlight that is gotten on earth is depends upon place, time of day, time of year, and weather.
Solar Energy Truths – Below are 10 Facts on Solar Energy
Truth 1: Solar energy is a totally free source of energy and it is discovered in abundance. The sun is 90 million miles from the earth, it takes less than 10 minutes for light to travel from that much of distance.
Reality 2: Solar energy which consists of glowing heat and light from the sun can be harnessed with some modern technology like photo-voltaic, solar heating, synthetic photosynthesis, solar architecture and solar thermal electrical power.
Truth 3: The solar technology can be identified into active and passive. Photovoltaic panels and solar thermal collectors which harness solar energy are examples of active solar innovation. Passive innovation includes building rooms to enhance air circulation, orienting space to positively utilize sunshine.
Truth 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.
Reality 5: The water cycle is a crucial result of solar insulation. The earth, oceans and atmosphere take in solar radiation and their temperature rises.
Truth 6: Solar energy has also another use. By means of photosynthesis, solar energy is converted by green plants into chemical energy which develops the bio mass that comprises the fossil fuels.
Fact 7: Cultivation and farming look for to make the optimum use of solar energy. These consist of techniques like timing of mixing and growing cycles of plant varieties. Environment-friendly houses are likewise utilized to transform light into heat to promote year round cultivation of special crops.
Truth 8: Solar powered hot water systems make use of solar energy to heat water. In particular areas, 60 to 70 % of water used locally for temperatures as high as 60 degree Celsius can be offered by solar heating.
Fact 9: Solar chimneys are passive solar ventilation systems. Shafts connect the interior and exterior of the structure. The operating can be improved by glazing and making use of thermal mass materials.
Reality 10: Solar energy can also be used for making safe and clean, saline or brackish water. Without utilizing electrical power or chemicals, waste water can be dealt with. Creating salt from sea water is likewise among the oldest uses of solar energy.
