SOLAR POWER

ABOUT

Solar energy, radiation from the Sun capable of producing heat, causing chemical reactions, or generating electricity. The total amount of solar energy incident on Earth is vastly in excess of the world’s current and anticipated energy requirements. If suitably harnessed, this highly diffused source has the potential to satisfy all future energy needs.

In the 21st century solar energy is expected to become increasingly attractive as a renewable energy source because of its inexhaustible supply and its nonpolluting character, in stark contrast to the finite fossil fuels coal, petroleum, and natural gas. click here to load more


The Sun is an extremely powerful energy source, and sunlight is by far the largest source of energy received by Earth, but its intensity at Earth’s surface is actually quite low. This is essentially because of the enormous radial spreading of radiation from the distant Sun.

A relatively minor additional loss is due to Earth’s atmosphere and clouds, which absorb or scatter as much as 54 percent of the incoming sunlight. The sunlight that reaches the ground consists of nearly 50 percent visible light, 45 percent infrared radiation, and smaller amounts of ultraviolet and other forms of electromagnetic radiation.solar energy, radiation from the Sun capable of producing heat, causing chemical reactions, or generating electricity.

The total amount of solar energy incident on Earth is vastly in excess of the world’s current and anticipated energy requirements. If suitably harnessed, this highly diffused source has the potential to satisfy all future energy needs.

The potential for solar energy is enormous, since about 200,000 times the world’s total daily electric-generating capacity is received by Earth every day in the form of solar energy. Unfortunately, though solar energy itself is free, the high cost of its collection, conversion, and storage still limits its exploitation in many places. Solar radiation can be converted either into thermal energy (heat) or into electrical energy, though the former is easier to accomplish.

PHOTOVOLTAIC

Solar radiation may be converted directly into electricity by solar cells (photovoltaic cells). In such cells, a small electric voltage is generated when light strikes the junction between a metal and a semiconductor (such as silicon) or the junction between two different semiconductors. (See photovoltaic effect.)

The power generated by a single photovoltaic cell is typically only about two watts. By connecting large numbers of individual cells together, however, as in solar-panel arrays, hundreds or even thousands of kilowatts of electric power can be generated in a solar electric plant or in a large household array.

The energy efficiency of most present-day photovoltaic cells is only about 15 to 20 percent, and, since the intensity of solar radiation is low to begin with, large and costly assemblies of such cells are required to produce even moderate amounts of power.

SOLAR CELL

When sunlight strikes a solar cell, an electron is freed by the photoelectric effect. The two dissimilar semiconductors possess a natural difference in electric potential (voltage), which causes the electrons to flow through the external circuit, supplying power to the load. The flow of electricity results from the characteristics of the semiconductors and is powered entirely by light striking the cell.

Small photovoltaic cells that operate on sunlight or artificial light have found major use in low-power applications—as power sources for calculators and watches, for example. Larger units have been used to provide power for water pumps and communications systems in remote areas and for weather and communications satellites. Classic crystalline silicon panels and emerging technologies using thin-film solar cells, including building-integrated photovoltaics, can be installed by homeowners and businesses on their rooftops to replace or augment the conventional electric supply.

WHY SOLAR?

  • Non Polluting,
  • No recurring fuel costs,
  • Eco friendly and clean source of power,
  • Life span of more than 25Years – Solar Modules,
  • Highly Reliable, Regulated and Consistent power supply,
  • Very Good Power output with steady Voltage and Frequency,
  • Very Low Maintenance Costs and Cleaning Costs,
  • Installed at site so very less Transmission Loses,
  • High Return of Investment.

The Government of India is backing the harnessing of non-polluting renewable solar energy resources. To promote the use of solar energy for power generation and other uses the Government of India has set up a Solar Mission - a part of the National Action Plan on climate change, with the objective of making solar energy efficient enough to compete with the other power generation options. The Government is now keen in deploying the Photo Voltaic Systems also called as the PV Systems for power generations in various parts of the country where grid connectivity is still not available or feasable.

With the Cost of Solar based systems going down with each passing year and appreciation for the need for development of solar power, solar power projects have been preffered by many individuals and industries. A significant part of the large potential of solar energy in the country could be developed by promoting solar photovoltaic power systems of varying sizes as per the need and affordabilty coupled ensuring adequate Return On Investment(ROI). India is blessed with ample amount of sunlight almost throughout the year, Power generation through solar power plants is turning out to be very efficient and cost effective, Solar power modules have very minimum maintenance cost and very long life more than 25 years.

Now with the facility of Net Metering the excess solar power could be fed back to the Electricity Department clients are making a use of this facility in making their electricity bills redundant by supplying excess energy produced by the Solar Systems back to the Electricity Department.

Understanding the movement of the sun in the sky, during summers let’s say on the 21st of June through winters let’s say on the 21st of December, in the Figure (i) below you will notice that the sun on 21st of June is high up in the sky which is measured at 84° up in the sky from the horizontal plane being the earth in the region of New Delhi whereas in winters the sun declines in the sky up till 38° as measured from the horizontal plane, this distance in degrees between the summer and the winter can be calculated at 46° throughout the year, in the typical region of New Delhi.

figure(i)

Now, Ideally sunlight should fall perpendicularly to the solar panels to be most efficient as shown in Figure (ii), while the sun travels in the sky from June to December this is not the case, for most part the sun is not perpendicular to the solar panels, which results in reduced efficiency of the system.

figure(ii)

While the sun travels in the sky from June to December this is not the case, for most part the sun is not perpendicular to the solar panels, which results in reduced efficiency of the system. We have showed how the panels mounted on fixed structures are less efficient through out the year as the sun moves in the sky for most part of the year, people in New Delhi and adjoining areas fix the panels at angles of 18° – 25° which makes the power generation less efficient, in New Delhi the solar systems mounted on fixed axis are less efficient by 13% as compared to the those perpendicular to the sun’s axis, so we came up with this method of tilting the solar panels throught the year keeping them perpendicular to the sun with most part of the year and called it SUN-ALIGN®

figure(iii)

In fixed structures our general study showed that the efficiency of the generation decreases by 6 % while the sun travels in the sky - 20° away from the perpendicular axis of the solar panel down to 94%, further 10° away from the perpendicular axis of the solar panel the efficiency drops another 7% down to 87%, that is equal to producing 87 unit while you could produce 100 units from the same Solar panels.
