Solar Energy Facts

source:conserve-energy-future\r\n\r\nThe consumption of non-renewable sources like oil, gas and coal is increasing at an alarming rate. The time has finally come to look after some other renewable sources of energy i.e. solar, wind and geothermal energy. Although many countries have started utilizing solar energy extensively but still they have to go a long way to exploit this energy to fulfill their daily demand for energy. Here are few facts on solar energy that can help you assess the potential of solar energy to meet global requirements.\r\n

What is Solar Energy?

\r\nSolar 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. Solar energy technologies use the sun’s energy to light homes, produce hot water, heat homes and electricity.\r\n\r\nThe main benefit of solar energy is that it does not produce any pollutants and is one of the cleanest source of energy. It is a renewable source of energy, requires low maintenance and are easy to install. The only limitation that solar energy possess is that it cannot be used at night and amount of sunlight that is received on earth is depends on location, time of day, time of year, and weather conditions.\r\n\r\nSolar_energy_facts\r\n

Below are 40 Facts on Solar Energy

\r\nFact 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.\r\n\r\nFact 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.\r\n\r\nFact 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.\r\n\r\nFact 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.\r\n\r\nFact 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.\r\n\r\nFact 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.\r\n\r\nFact 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.\r\n\r\nFact 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.\r\n\r\nFact 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.\r\n\r\nFact 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.\r\n\r\nFact 11: Clothes can be dried in the sun using clothes lines, cloth racks etc.\r\n\r\nFact 12: Food can be cooked, dried or pasteurized using solar energy.\r\n\r\nFact 13: Solar power is the most exciting use of solar energy. It is how solar energy is converted into electricity by using either photo-voltaic (direct method) or concentrated solar power (Indirect). Large beams of sunlight are focused into a small beam using mirrors or lenses in the case of concentrated solar power. Photoelectric effect is used by Photo voltaic to convert solar energy into electric energy.\r\n

\r\nFact 14: Solar chemical processes replace fossil fuels as a source for chemical energy and can make solar energy storable and transportable. Photosynthesis can create a variety of fuels. Technology for producing Hydrogen is a major area of solar chemical research.\r\n\r\nFact 15: Thermal storage systems can store solar energy in the form of heat by using common materials with high specific heat such as stone, earth and water. Solar energy can be stored also in molten salts.\r\n\r\nFact 16: The oil crisis of 1970 revealed the delicate nature of fossil fuels as a source of energy for the world. As such research in alternative, renewable energy technology like that of solar and wind energy gained momentum.\r\n\r\nFact 17: Solar energy is being recognized as the future of alternative energy sources as it is non polluting and helps combat the Greenhouse effect on global climate created by use of fossils fuels.\r\n\r\nFact 18: Common domestic use of solar energy is from solar panels which absorb solar energy to use for cooking and heating water.\r\n\r\nFact 19: Solar energy produce no pollution, have no environmental effects and is ecologically acceptable.\r\n\r\nFact 20: Solar energy is one of the most widely used renewable source of energy. One can use renewable energy technologies to convert solar energy into electricity.\r\n\r\nArray_of_solar_panels\r\n\r\nFact 21: Space missions by various countries use solar energy to power their spaceships.\r\n\r\nFact 22: Solar energy is very reliable source of energy.\r\n\r\nFact 23: With new advancements in scientific researches, solar energy could be more affordable in future with decreasing costs and increasing efficiency.\r\n\r\nFact 24: Solar energy could prove to be the major source of renewable energy because of its massive potential and long-term advantages.\r\n\r\nFact 25: The earth receives about 1,366 watts of direct solar radiation per square meter.\r\n\r\nFact 26: The largest solar power plant in the world is located in the Mojave Desert in California, covering 1000 acres.\r\n\r\nFact 27: Solar energy is the preferred mode of creating power where the need is temporary. For e.g.: temporary fairs, mining sites, Olympics.\r\n\r\nFact 28: Solar energy can also be used to power calculators.\r\n\r\nFact 29: Solar panels are virtually maintenance free since the batteries require no water or other regular service and will last for years. Once, solar panels are installed, there are no recurring costs.\r\n\r\nFact 30: Solar power can significantly reduce the electricity bills. Moreover, there are many tax incentives and rebate programs designed to spur the use of solar, and save home owners money at the same time.\r\n\r\nFact 31: Solar power is noise pollution free. It has no moving parts, and does not require any additional fuel, other than sunlight, to produce power.\r\n\r\nFact 32: A home solar panel system consists of several solar panels, an inverter, a battery, a charge regulator, wiring, and support materials. Sunlight is absorbed by the solar panels and is converted to electricity by the installed system. The battery stores electricity that can be used at a later time, like cloudy days or during the evening.\r\n\r\nFact 33: By relying on battery backup, solar energy can even provide electricity 24×7, even on cloudy days and at night.\r\n\r\nFact 34: Solar Energy is measured in kilowatt-hour. 1 kilowatt = 1000 watts.\r\n\r\nFact 35: Though solar energy is used on a wide scale, it only provides a small fraction of the world’s energy supply.\r\n\r\nFact 36: Solar energy is used in many applications including Electricity, Evaporation, Biomass, Heating water and buildings and even for transport.\r\n\r\nFact 37: Large investment is one the primary reason why solar energy is not still not used by many people all over the world.\r\n\r\nFact 38: Solar energy has been used for over 2700 years. In 700 BC, glass lenses were used to make fire by magnifying the sun’s rays.\r\n\r\nFact 39: The sun is also the main source of non-renewable fossil fuels (coal, gas and petroleum) which began life as plants and animals millions of years ago.\r\n\r\nFact 40: Clouds and pollution prevent the sun’s rays from reaching the earth.\r\n\r\nEvery year the sun beams to the earth energy to sustain global needs of energy for the entire year. Solar energy is a technology used to convert solar energy into other forms like electrical energy to meet global requirements. As of now only one tenth of global energy needs is supplied by solar energy but the potential for the future is mind boggling.\r\n\r\n- See more at: http://www.conserve-energy-future.com/various-solar-energy-facts.php#sthash.xZFyn3Ba.dpuf

First Solar and Apple sign $848 million 130 MW deal

\r\nsource:pv-magazine.com\r\n\r\n11. FEBRUARY 2015 | APPLICATIONS & INSTALLATIONSFINANCIAL & LEGAL AFFAIRSMARKET & TRENDS | BY:  JONATHAN GIFFORD\r\n

First Solar has signed a 25-year PPA with Apple for 130 MW of a 150 MW plant. Under the deal Apple will pay $848 million for electricity from the plant, which First Solar will begin construction on in mid-2015

Apple with power its headquarters and stores, in a virtual sense, with electricity from the California Flats array.\r\n

\r\n

\r\n

\r\nFirst Solar continues to pursue its strategy of supplying utility-scale solar to large electricity consumers with the latest deal seeing it supply computing giant Apple. Both companies share prices rose on news of the deal, with Forbes noting an almost 5% surge in First Solar shares and Apple 1.9% by the close of trading yesterday.\r\n\r\nThe solar park will be located in Monterey County south of San Francisco on a property owned by Hearst Corporation. Apple will vitrually power its Californian headquarters and its stores will the clean electricity produced at the site. The project will cover 2,900 acres (8,094 square meters).\r\n\r\nThe remaining 20 MW of the 150 MW California Flats Solar Project not purchased by Apple will be sold to Pacific Gas & Electric (PG&E) under a “long term PPA.”\r\n\r\n”Apple’s commitment was instrumental in making this project possible and will significantly increase the supply of solar power in California,” said Joe Kishkill, First Solar’s CCO. Kishkill noted that Apple is demonstrating how large companies can source 100% of their electricity from renewable sources.\r\n\r\nThe solar park received unanimous approval from the Monterey County Planning Commission with final regulatory sign off to be provided by the Monterey County Board of Supervisors.\r\n\r\nForbes notes that the California Flats Solar Project is the fourth solar farm Apple has funded. Two Apple PV arrays are located in North Carolina and one in Nevada.\r\n\r\nGreenpeace celebrated the deal, in a statement today, saying that other Fortune 500 CEOs should look to Apple as positive renewable energy roll model.\r\n\r\n”It’s one thing to talk about being 100% renewably powered, but it’s quite another thing to make good on that commitment with the incredible speed and integrity that Apple has shown in the past two years,” said Greenpeace Senior IT Sector Analyst Gary Cook. However he added that Apple “still has work to do to reduce its environmental footprint.”\r\n\r\nFirst Solar claims that the Apple project marks the industry’s largest commercial power deal.\r\n\r\n
