What is solar energy?Solar energy refers to the energy from the Sun. The Sun has produced energy for billions of years. It is the source of energy for life forms, the most important. It is a renewable source of energy is not the same as non-renewable resources such as fossil fuels. The technology of solar energy using solar energy to light homes, producing heat, electricity and hot water.The main advantage of solar energy is that it does not produce any pollutants and is one of the cleanest sources of energy. It is a renewable energy source, require low maintenance and easy to install. The only drawback of solar energy is that it can not be used at night and the amount of sunlight received on Earth is dependent on the location, time of day, time of year, and weather conditions.Here are 40 solar eventsFact 1: solar energy is free energy sources and it is found in abundance. Although the Sun is 90 million miles from Earth, it takes less than 10 minutes for light to travel from which many distances.Fact 2: solar energy include heat and light radiation from the Sun can be exploited with a number of modern technologies such as solar energy, heat, artificial photosynthesis, solar architecture, solar and thermal power.Fact 3: solar technology can differentiate into active and passive. The photovoltaic panels and solar thermal collectors exploit the Sun's energy is the example of solar technology works. Passive technologies including building rooms to improve air circulation, spatial orientation to facilitate use of sunlight.Fact 4: the Earth receives 174 Petawatts of incoming solar radiation in the upper atmosphere. About 30% is reflected back into space and the rest is absorbed by the oceans, clouds and land masses.Fact 5: The water cycle is an important result of the insulation material of solar energy. The Earth, the oceans and the atmosphere absorbs solar radiation and temperature increased. Warm air rising from the ocean, causing convection. When this machine increases to higher altitude, clouds are generated by condensation of water vapor. The clouds causing rains, bring the water back to the ground to complete the water cycle.Fact 6: solar energy also has other uses. By means of photosynthesis, solar energy is converted by the chemical energy plants that make biology volume generating fossil fuels.Fact 7: horticulture and Agriculture seeks to make maximum use of solar energy. They include techniques such as planting cycle time and mixing of plant varieties. Green Home is also used to convert light into heat to promote year-round growing of crops specifically.Fact 8: systems solar water heaters are supported using solar energy to heat water. In some areas, 60-70% of water is used in water with a temperature of up to 60 degrees Celsius can be made available by the solar heating system.Fact 3: The solar chimney is ventilation systems passive solar. The axis connecting the Interior and exterior of the building. The activities can be improved by glasses and use heat treatment.Fact 1: solar energy can also be used to make drinking water, brackish or salty. Do not use electricity or chemicals, waste water can be treated. Create the salt from sea water is also one of the oldest uses of solar energy.
