Technical field of invention: Present invention in general relates to design and develop dual axis energy efficient solar power optimizing system and in particular to a tracking mechanism system for harnessing solar energy. Prior art: Electrical power generation by various conventional and renewable methods plays an important role in GDP growth and standard of living of people in a country. The GDP growth of a country and HDI (Human Development Index) are interrelated. At present HDI of India is 0.609 and it ranks 130th position in the world. The per capita consumption of India is 1010 Kwh/year with 137th portion in the world. In the recent past one of the major thrust in the era of power generation is to generate power by renewable energy systems like wind, solar thermal, solar photovoltaic, biomass generation, biogas and small hydro. The pollution levels, greenhouse gas emission and global worming are the alarming issues which are becoming detrimental to human civilization. Renewable energy systems are proving advantageous to combat these three problems. India is highly polluted country, with non-uniform distribution of population over its land. One of the major issues with government is to increase per capita energy consumption which direct relates to HDI and GDP of country. Hence various attempts are made which are discussed below.

US 8895836 B2 discloses dual axis solar tracker apparatus and method. The dual axis solar tracker apparatus and method uses an azimuth actuator to adjust the azimuth of an attached solar panel and an elevation actuator to adjust the elevation of a panel seat holding the solar panel to track the azimuth and elevation of the sun as it moves through the sky. The panel seat rotatably supports the solar panel with two pins, and a support structure supports the panel seat with an elevation tracking pivot.

STATEMENT: Accordingly following invention provides a design and developed dual axis energy efficient solar power optimizing system. The present invention provides an easy to operate simple and rugged tracking mechanism system for harnessing solar energy with energy efficient tracking system. This newly developed mechanism uses a stepper motor which is programmed and driven by microcontroller (PIC18F452) to track the sun on azimuth angle on daily basis. The sun rise and sun set timings of all 365 days in a year at Nagpur location (79° 7’E; 21°7’N) have been fed into microcontroller. The PIC18F452 has a flash memory for program storage and can be reprogrammed according to new requirement at new locations. The stepper motor receives power from driver circuit which takes commands from microcontroller. The day light hours for which solar radiation is available, changes on each day. They are minimum for 21st December and maximum for 22nd June. The controller compares the daylight hours and starts giving signals for stepper motor movement after 15° advancement of sun during sun rise. It stops giving commands after 150° rotation of solar panel, just before 15° left for sun set. Thus the solar panels track the sun for 150° on azimuth angle on daily basis. The inclination angle (zenith angle) has a change of 8° in every month. This comes out to be 2° for every week. This is done by providing a worm screw arrangement for lifting the housing accommodating stepper motor, worm reduction gear and main shaft for azimuth angle tracking along with solar panels. Thus the optimum tilt of solar panels (w. r. t. vertical) at Nagpur is 46° in December which goes up to 92° in June. This gradually decreases from July and again comes to 46° in December. Thus a total zenith angle travels of 46° (92°- 46°).
