Solar Energy Power And Solar Energy Advantages

What is Solar Energy Power?

Solar Energy is stored in the form of Petroleum, natural gas, wood & hydroelectricity. It has been used to power all the machines. There are side effects inefficiencies other limitations in the above forms of solar energy. Now efforts are being made run the machines by converting direct Solar Energy. When we start using solar energy for chemicals electrical & thermal processes, we will start understanding the physical world around us. After understanding this, if we start using the solar energy, our life will change completely.
Solar Energy Power will become 2nd natural source for all, when the rulers, economists, managers, engineers & all other understand the solar power, our environment, pattern of life, structured form will change.
The Shift from passive fossil fuel age to new solar power energy will be quite difficult. We will have to learn the new techniques to save our earth.
Very interesting to know, every year 3 ½ times the energy needed by all of us falls on our roof tops. So far this resource of energy has been ignored. This solar energy is available sufficient to every body in quality & quantity. We must plan the future use of solar power energy.

Solar Energy Statistics

Sun transmits energy. 1.5 X 1021 watt-hours (thermal) of solar radiation is received by upper atmosphere of Earth every year. This energy is 23,000 times that of used by the human population. Sun produces two-billion times the energy used by the human population.
It is measurement of power density of solar radiation outside Earth’s atmosphere and over the entire solar spectrum
Most reliable (1981) value for the solar constant is 1370 + 6 w / m2 according to the World Meteorological Organization.
8% power, is in the ultraviolet wavelengths
47% power, is in the visible spectrum
45% in the infrared region
Solar constant. is not constant, due to the shape of Earth’s orbit.
It is+ 3.4% about January 3, when Earth is closest to the Sun. – 3.3% from average about July 5, when Earth is at its greatest distance from the Sun
Solar radiation reduces in force before reaching Earth’s surface. This is due to reflection, scattering and absorption by atmosphere that reduces part of energy. Solar radiation reaching earth is more than 10,000 times the total world’s energy use.
Diffuse radiation: Radiation scattered by striking gas, molecules, water vapor or dust particles.
Clouds are most important scattering and reflecting agents ,These are capable of reducing radiation up to 80%.. But it can not be predicted.
The radiation from the Sun is called direct or beam radiation.
Global radiation is total solar radiation on the surface .
Modern Research In Solar Technology is focused on most efficient
ways of capturing solar energy. It also researches to convert captured energy to useful purposes. Other power sources which are the indirect forms of solar energy: wind, biomass, hydro power and the tropical ocean surfaces. Most of these energy resources is largely untapped.
Major technologies using solar energy
(1) The heat content of solar radiation is used to provide moderate-temperature heat for space comfort conditioning of buildings,
(2) Moderate and high – temperature heat for industrial processes and high –
(3) Temperature heat for generating electricity.
(2) Photovoltaic’s convert solar energy directly into electricity.
(3) Biomass technologies exploit the chemical energy produced through photosynthesis (a reaction energized by solar radiation) to produce energy – rich fuels and chemicals and to provide direct heat for many uses.
(4) Wind energy systems generate mechanical energy, primarily for conversion to electric power.
(5) Finally, a number of ocean energy applications are being pursued; the most advanced is ocean thermal energy conversion, which uses temperature differences between warm ocean surface water and cooler deep water to produce elect
Depending on atmospheric thickness and content
Atmospheric absorption and scattering amount of solar radiation depends upon the distance through which the radiation travels.
Spectral irradiance is a function of air mass.
Air mass zero represent zero mass of air through which the Sun’s rays must pass
The solar declination, the angle between the Earth-Sun line and Earth’s equatorial plane,
It varies as Earth circles the Sun and this affects the solar radiation reaching the ground.
Amount of solar energy incident on a horizontal surface at sea level
=ranges up to 2400 Btu/ft2 – day (7 kWh/m2-day).
The sites between latitudes 35° N and 35°S receive between 2000 and 3500 h of sunshine per year; higher latitudes receive less.
