The water from the dam flows down through pipes and rotates the turbines of generators to produce electricity. First sunlight may be absorbed converted and retransmitted as lower energy radiation with longer wavelengths such as infrared light.

Solar Panel Technology Ppt

Solar thermal panels are filled with water which heats up in the sunlight.

Solar energy and the atmosphere ppt. Glass sheets Evaluation COLLECTOR ENERGY BALANCE Cheap design possible Energy required to heat water from 20 to 100C. Solar energy accounted for 01 per cent of world. Infrared radiation is reradiated into lower atmosphere warming.

Ii The electricity produced does not cause pollution. Using solar energy can have a positive indirect effect on the environment when solar energy replaces or reduces the use of other energy sources that have larger effects on the environment. Once sunlight does enter the atmosphere lets look at what happens next.

Atmosphere does all four things Most important among these is absorption of longwave Earth-reemitted or transformed radiation Various gases capture this energy which warms the Earths atmosphere 100 total 100 total 7 Earth radiation to space 63 Sky radiation to space 30 100 Reflected Radiation Solar radiation Outflow Inflow 96 Radiation to Surface 159 total 12 Conduction 20 Condensation 159 63 107 20 Radiation to space Solar. Solar photovoltaic PV cells use the suns energy to convert are made from two layers of silicon crystal. Solar Power Power derived directly from sunlight Seen elsewhere in nature plants We are tapping electromagnetic energy and want to use it for heating or convert it to a useful form usually electricity Renewable-we wont run out of sunlight in its current form for another 4-45 billion years.

Total energy enter the earths atmosphere. Without the atmosphere it would be -18C -04F About 33C or 594F colder. Solar shortwave radiation vs.

Solar energy and Earths Rotation Primary forces - initiate water movement wind stress density differences thermal expansion Secondary forces - modify direction and intensity of flow coriolis effect gravity friction shape of the ocean basins. Atmosphere is the most important component of the earths climate. 20108 1-800-875-5029 Exploring Solar Energy Student PAGE 5.

However some toxic materials and chemicals are used to make the. Solar energy systemspower plants do not produce air pollution or greenhouse gases. The heated water is then pumped through a tank heating the water that is connected to the taps in the house.

0013 waste and fossil fuel. Radiation -Heat Transfer The Greenhouse Effect and Atmospheric Warming Water vapor CO 2 CFCs NOs absorb infrared energy. Solar energy is free and its supplies are unlimited.

Solar Energy and Earths Atmosphere. Atmosphere delays transfer of. How Solar Energy Can Benefit The Environment - Solar energy provides many benefits for the environment over traditional electricity generation process as it saves the water protects earth from the greenhouse effect reduces air pollution and several more like this.

Solar power is generated directly from sunlight photons. From Sun to Earth The Seasons Atmospheric Composion Temperature and Funcon Variable Atmospheric Components Earths Orbit Average distance from Earth to. It cannot be controlled by any one nation or industryIf wecan improve the technology to harness the suns enormous powerwemaynever face energy shortages again.

Advantages-i Flowing water is a renewable source of energy. Two classifications of heat energy Layering of earths atmosphere General atmospheric density Normal adiabatic lapse rate and unusual twists Problems that generate pollution Lets put the Earth and Sun into perspective. PowerPoint PPT presentation.

The highest solar resource potential is in the Red Sea area including Egypt and Saudi Arabia. There are three processes that can take place once sunlight enters the atmosphere. Bodies with temperatures at this level or lower would emit their radiation in the longwave band.

General the absorption of solar radiation by substances in the Earths atmosphere results in temperatures that get no higher than 1800 C. 174 petawatts or 174X1015 Watts Solar. It does not pollute or otherwise damage the environment.

The rest is absorbed into Earths atmosphere. Further this emission of radiation is in all directions so a sizable proportion of this energy is lost to space. The Solar Atmosphere Spectral lines only tell us about the part of the Sun that forms them photosphere and chromosphere but these elements are also thought to be representative of the entire Sun.

Chromosphere Chromosphere seen during full Solar eclipse Chromosphere emits very little light because it is of low density Reddish hue due to 3 2 6563 nm line emission from Hydrogen. Solar power is power generated directly from sunlight. Natural Solar Energy Greenhouse Effect The infrared visible and UV waves that reach the Earth take part in a process of warming the planet and making life possiblethe so-called greenhouse effect About 30 of the solar energy that reaches Earth is reflected back into space.

1011 World solar energy resources and market The worlds overall solar energy resource potential is around 56 gigajoules GJ 16 megawatt-hours MWh per square metre per year. The primary source of all energy on planet Earth is from the sun - plants get energy from the sun for photosynthesis and weotheranimals eat the plants to gain energy heat from the sun also drives atmospheric circulation which controls the wind tides and waves. 140C in September 2015 Double glazing required Insulation material cheap Collector model THERMAL IMAGE Solar thermal collector tests COLLECTOR IN OPERATION RESULTS 140C with 23C ambient temperature 700 Wm2 insolation stagnation temperature Important cost factor.

Disadvantages-i The initial cost is high. Iii The water stored in dams can also be used to control floods and for irrigation. A real greenhouse traps heat inside.

320 kJkg Operating temperature of 120C with 60 efficiency possible Energy. Solar Energy Seasons and the Atmosphere The Solar System Sun and Earth Solar Energy.
