Description
Solar energy is an inexhaustible resource. The sun produces vast amounts of renewable solar energy that can be collected and converted into heat and electricity. Texas, due to its large size and abundant sunshine, has the largest solar energy resources among the states. Several other states, however, lead the nation in terms of using solar energy, mostly due to state policies and incentives that encourage the installation of solar energy systems. California is the nation’s largest solar energy market by far, and has effective state initiatives promoting the industry. Other states with notable markets for solar energy include New Jersey, Arizona, Colorado and New York.
Even so, in 2006 solar energy accounted for just 0.01 percent of all U.S. electricity, mainly because of its higher costs compared to other power options. 1. Solar energy plays an even smaller role in the Texas electricity market. Still, Texas has the sunshine, manufacturing base and research institutions needed to become a leader in the development of solar energy.2 The state is well positioned to compete with other states and countries in a global solar energy market worth $10.6 billion in 2006.3 One study estimates that Texas could capture about 13 percent of all new jobs and investments related to solar photovoltaic technologies by 2015, primarily in manufacturing.
Solar Thermal
Solar Thermal Technology is employed for collecting & converting the sun energy to heat energy for application such as water & air heating, cooking & drying, steam generation, distillation, etc. Basically a solar thermal device consists of a solar energy collector - “the absorber”, a heating or heat transferring medium and a heat storage or heat tank. Solar thermal technology employs an elaborate use of a black body, good heat conducting materials, insulation and reflectors. Solar geyser, solar concentrators, solar cookers, solar still are some example of devices based on solar thermal technology.
Solar Photovoltaic (SPV)
Solar Photovoltaic Technology is employed for directly converting solar energy to electrical energy by the using “solar silicon cell”. The electricity generated can be utilized for different applications directly or through battery storage system. Solar PV has found wide application in rural areas for various important activities besides rural home lighting. Remote villages deprived of grid power can be easily powered using the Solar Photovoltaic technology. The economics of rural electrification can be attractive considering the high cost of power transmission and erratic power supply in the rural areas.
Solar Passive for Buildings
In Solar Passive the solar energy can be put into use by incorporating appropriate designs in buildings itself to maximize utilization of solar energy for various purposes such as lighting, seasonal air conditioning, water & space heating/cooling and thereby reduce external energy inputs.
WORKING
Our project is working on solar energy. Solar energy is an inexhaustible resource. The sun produces vast amounts of renewable solar energy that can be collected and converted into heat and electricity. Our project’s main advantage is that it is totally pollution free and this type of technology is very useful in monsoon season when clouds are there at some place and sunlight is there on other place.
In our project we have use.LDR sensor which is named as Light Dependent Resistor. It sense the light due to which motor starts and stop. This sensor is attached none the reflector. Reflector is bolted with the horizontal angle plate which is bolted with bearing cap on stand of container. So with the reference of that bearing reflector revolve around it axis. Motor is connected with the LDR (Light Dependent Resistor) circuit. For the supply of electric current 12v battery is used.
ADVANTAGE
• Unlike oil, gas, ethanol, and coal plants, space solar power does not emit greenhouse gas
• Unlike coal and nuclear plants, space solar power does not compete for or depend upon increasingly scarce fresh water resources.
• Unlike bio-ethanol or bio-diesel, space solar power does not compete for increasingly valuable farm land or depend on natural-gas-derived fertilizer. Food can continue to be a major export instead of a fuel provider.
• Unlike terrestrial solar and wind power plants, space solar power is available 24 hours a day, 7 days a week, in huge quantities. It works regardless of cloud cover, daylight, or wind speed.
• Unlike nuclear power plants, space solar power does not provide easy targets for terrorists.
• Unlike coal and nuclear fuels, space solar power does not require environmentally problematic mining operations.
• Space solar power will provide true energy independence for the nations that develop it, eliminating a major source of national competition for limited Earth-based energy resources.
• Space solar power will not require dependence on unstable or hostile foreign oil providers to meet energy needs, enabling us to expend resources in other ways.
• Space solar power can take advantage of our current and historic investment in aerospace expertise to expand employment opportunities in solving the difficult problems of energy security and climate change.
• Space solar power can provide a market large enough to develop the low-cost space transportation system that is required for its deployment. This, in turn, will also bring the resources of the solar system within economic reach.
CONCLUSION
By this project we have conclude that solar energy is very effective & efficient energy. Use of this energy can solve the energy problem of the world.
This project is echo friendly & does not make any harm full gases as by product. Source of this energy is unlimited.
Using solar energy for thermal purpose is very easy to understand & implement. Solar energy is converting into heat energy and that heat energy is being used in our project.
